1.4. Terminologies and acronyms

This section will define commonly used terms in this manual. These terms are related to

Internetworking, and defined in regards to their use with Pro Series.

MAC address

On a local area network or other network, the MAC (Media Access Control) address is the computer's unique hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)

It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique

Identifier) number and 6-digit hardware identifier number. The Pro Series has the following MAC address template: 00-01-95-xx-xx-xx. The MAC address can be found on the bottom of the original package.

Host

A user’s computer connected to the network

Internet protocol specifications define "host" as any computer that has full two-way access to other computers on the Internet. A host will have a specific "local” or “host number" that, together with the network number, forms its unique IP address.

Session

A series of interactions between two communication end points that occur during the span of a single connection

Typically, one end point requests a connection with another specified end point. If that end point replies, agreeing to the connection, the end points take turns exchanging commands and data ("talking to each other"). The session begins when the connection is established at both ends and terminates when the connection is ended.

Client/Server

Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request.

A server is a computer program that provides services to other computer programs on one or many computers. The client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.

2.3. Accessing the Web Browser Management Interface

The Pro Series supports both HTTP and HTTPS (HTTP over SSL) protocols. The Pro Series also provides has its own Web management pages. To access the Pro Series Web management page, enter the IP address or resolvable hostname of the Pro Series into the web browser’s URL/Location field. This will direct the user to the Pro Series login screen. The user must authenticate themselves by logging into they system with a correct user name and password. The factory default settings are:

Login: root Password: root

Note: Before accessing the Pro Series Web management page, the user must check the IP address

(or resolvable Hostname) of the Pro Series and Subnet mask settings.

Figure 2-18 Login screen of the Pro Series web management

Figure 2-18 shows Login screen of the Pro Series web management.

Figure 2-19 shows the configuration homepage of the Pro Series Web management interface. A menu bar is provided on the left side of the screen. The menu bar includes the uppermost configuration menu groups. Selecting an item on the menu bar opens a tree view of all the submenus available under each grouping. Selecting a submenu item will allow the user to modify parameter settings for that item. Every page will allow the user to [Save], [Save & apply] or [Cancel] their actions.

After changing the configuration parameter values, the users must select [Save] to save the changed parameter values to the non-volatile memory. To apply all changes made, the user must select

[Apply Changes]. This option is available on the bottom of the menu bar. Only when the user selects

[Apply changes] will the new parameter values be applied to the Pro Series configuration. The user also can select [Save & apply] to save parameters and apply changes in one step.

If the user does not want to save the new parameter values, the user must opt to [Cancel]. All changes made will be lost and the previous values restored. But the changes that are already saved or applied cannot be canceled.

3. Network Configuration

3.1. IP Configuration

The Pro Series requires a valid IP address to operate within the user’s network environment. If the IP address is not readily available, contact the system administrator to obtain a valid IP address for the

Pro Series. Please note that the Pro Series requires a unique IP address to connect to the user’s network.

The users may choose one of three Internet protocols in setting up the Pro Series IP address: i.e.,

•

Static IP

•

DHCP (Dynamic Host Configuration Protocol)

The Pro Series is initially defaulted to STATIC mode, with a static IP address of 192.168.161.5

. Table

3-1 shows the configuration parameters for all three IP configurations. Figure 3-1 shows the actual web-based GUI to change the user’s IP configuration.

3.1.1. Using a Static IP Address

When using a Static IP address, the user must manually specify all the configuration parameters associated with the IP address of the Pro Series. These include the IP address, the network subnet mask, the gateway computer and the domain name server computers. This section will look at each of these in more detail.

Note: The Pro Series will attempt to locate all this information every time it is turned on.

IP address

A Static IP address acts as a “static” or permanent identification number. This number is assigned to a computer to act as its location address on the network. Computers use these IP addresses to identify and talk to each other on a network. Therefore, it is imperative that the selected IP address be both unique and valid in a network environment.

Note : 192.168.1.x will never be assigned by and ISP (Internet Service Provider). IP addresses using this form are considered private. Actual applications of the Pro Series may require access to public network, such as the Internet. If so, a valid public IP address must be assigned to the user’s computer.

A public IP address is usually purchased or leased from a local ISP.

Subnet mask

A subnet represents all the network hosts in one geographic location, such as a building or local area network (LAN). The Pro Series will use the subnet mask setting to verify the origin of all packets. If the desired TCP/IP host specified in the packet is in the same geographic location (on the local network segment) as defined by the subnet mask, the Pro Series will establish a direct connection. If the desired TCP/IP host specified in the packet is not identified as belonging on the local network segment, a connection is established through the given default gateway.

Default gateway

A gateway is a network point that acts as a portal to another network. This point is usually the computer or computers that control traffic within a network or a local ISP (Internet service provider).

The Pro Series uses the IP address of the default gateway computer to communicate with hosts outside the local network environment. Refer to the network administrator for a valid gateway IP address.

Primary and Secondary DNS

The DNS (Domain Name System) server is used to locate and translate the correct IP address for a requested web site address. A domain name is the web address (i.e. www.yahoo.com

) and is

25

usually easier to remember. The DNS server is the host that can translate such text-based domain names into the numeric IP addresses for a TCP/IP connection.

The IP address of the DNS server must be able to access the host site with the provided domain name. The Pro Series provides the ability to configure the required IP addresses of both the Primary and Secondary DNS servers addresses. (The secondary DNS server is specified for use when the primary DNS server is unavailable.)

3.1.2. Using DHCP

Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network administrators manage and automate the assignment of IP addresses centrally in an organization's network. DHCP allows the network administrator the ability to Provise and distribute IP addresses from a central point and automatically send a new IP address when a computer is plugged into a different network location.

When in static IP mode, the IP address must be entered manually at each computer. If a computer is moved to another network location, a new IP address must be assigned. DHCP allows all the parameters, including the IP address, subnet mask, gateway and DNS servers to be automatically configured when the IP address is assigned. DHCP uses a “lease” concept in assigning IP addresses to a computer. It limits the amount of time a given IP address will be valid for a computer. All the parameters required to assign an IP address are automatically configured on the DHCP server side, and each DHCP client computer receives this information when the IP address is provided at its bootup.

Each time the device is reset, the Pro Series broadcasts a DHCP request over the network. The reply generated by the DHCP server contains the IP address, as well as the subnet mask, gateway address, DNS servers and the “lease” time. The Pro Series immediately places this information in its memory. Once the “lease” expires, the Pro Series will request a renewal of the “lease” time from the

DHCP server. If the DHCP server approves the request for renewal, the Pro Series can continue to work with the current IP address. If the DHCP server denies the request for renewal, the Pro Series will start the procedure to request a new IP address from the DHCP server.

Note : While in DHCP mode, all network-related parameters for the Pro Series are to be configured automatically, including the DNS servers. If the DNS server is not automatically configured, the user may manually configure the settings by entering the primary and secondary DNS IP addresses. To force an automatic configuration of the DNS address, set the primary and secondary DNS IP addresses to 0.0.0.0 (recommended).

A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the network administrator. This means that the DHCP client, i.e. the Pro Series, receives a different IP

26

address each time it boots up. The IP address should be reserved on the DHCP server side to assure that the user always knows the newly assigned Pro Series address. In order to reserve the IP address in the DHCP network, the administrator needs the MAC address of the Pro Series found on the label sticker at the bottom of the Pro Series.

3.2. SNMP Configurations

The Pro Series has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1 and v2 protocols. Network managers like NMS or SNMP Browser can exchange information with Pro

Series, as well as access required functionality.

SNMP protocols include GET, SET, GET–Next, and TRAPs. With these functions, a manager can be notified of significant events (TRAPs), query a device for more information (GET), and make changes to the device state (SET). SNMPv2 adds a GET–Bulk function for retrieving tables of information and security functions.

With the SNMP configuration panel, the user can configure MIB-II System objects, access control settings and TRAP receiver settings. The manager configured in this menu can perform both information exchange and action control. Figure 3-2 shows a SNMP configuration screen via a web interface.

27

Figure 3-2 SNMP Configuration

3.2.1. MIB-II System objects Configuration

MIB–II System objects configuration sets the System Contact, Name, Location, and Authenticationfailure traps used by the SNMP agent of the Pro Series. These settings provide the values used for the

MIB-II sysName, sysContact, sysLocation, sysService and enableAuthenTrap.

Brief descriptions of each object are as follows, sysContact: Identification of the contact person for the managed system (Pro Series), and a description of how to contact the person. sysName: Name used to identify the system. By convention, this is the fully qualified domain name of the node. sysLocation: The physical location of the system (e.g., Room 384, Operations Lab, etc.). sysService(Read Only) : A series of values, separated by commas, that indicate the set of services that the system provides. By default, Pro Series only supports an Application(7) service level.

28

EnablePoweronTraps: Indicates whether the SNMP agent process is permitted to generate power-on traps.

EnableAuthenTrap: Indicates whether the SNMP agent process is permitted to generate authentication-failure traps. The value of this object overrides any configuration information; as such, it provides a means whereby all authentication-failure traps may be disabled..

EnableLoginTrap: Indicates whether the SNMP agent process is permitted to generate system login traps for console, telnet and Web access.

If users need support for adding or modifying MIBs, please contact Sena technical support.

For more information about the MIBs and SNMP, see the RFCs 1066, 1067, 1098, 1317, 1318 and 1213.

3.2.2. Access Control Configuration

Access Control defines accessibility of managers to the Pro Series SNMP agent. Only the manager set in this menu can access Pro Series SNMP agent to exchange information and control actions. If there is no specified IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can access the Pro Series SNMP agent.

3.2.3. Trap Receiver Configuration

The Trap receiver defines managers, which can be notified of significant events(TRAP) from the Pro

Series SNMP agent.

3.2.4. Management using SNMP

The Pro Series can be managed through the SNMP protocol using NMS (Network Management

System) or SNMP Browser. Before using the NMS or SNMP Browser, the user must set the access control configuration properly so that the Pro Series permits host access where the NMS or SNMP

Browser is executed. Figure 3-3 shows a screen shot of a typical SNMP browser with MIB-II OIDs of the Pro Series SNMP agent.

29

Figure 3-3 Browsing MIB-II OIDs of Pro Series SNMP agent using SNMP Browser

(AdventNet MibBrowser)

3.3. Dynamic DNS Configuration

When users connect the Pro Series to a DSL line or use a DHCP configuration, the IP address might be changed whenever it reconnects to the network. It can therefore be very difficult to post all related contacts for each new IP address. In addition, if the administrator only has access through the remote console, there is no way to know if an IP address has changed, or what the new IP address is.

A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue.

By using the Dynamic DNS service, users can access the Pro Series through the hostname registered in the Dynamic DNS Server regardless of any IP address change.

By default, the Pro Series only supports Dynamic DNS service offered at Dynamic DNS Network

Services, LLC (www.dyndns.org). Contact Sena technical support for issues regarding other Dynamic

DNS service providers.

To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set

30

up an account in their Members' NIC (Network Information Center - http://members.dyndns. org). The user may then add a new Dynamic DNS Host link after logging in to their Dynamic DNS Network

Services Members NIC.

After enabling the Dynamic DNS service in the Dynamic DNS Configuration menu, the user must enter the registered Domain Name, User Name, and Password. After applying the configuration change, users can access the Pro Series using only the Domain Name.

Figure 3-4 shows the Dynamic DNS configuration web interface.

Figure 3-4 Dynamic DNS Configuration

3.4. SMTP Configuration

The Pro Series can send an email notification when the number of system log messages reaches to certain value and/or when an alarm message is created due to an issue with serial port data. The user must configure a valid SMTP server send these automatically generated emails. The Pro Series supports three SMTP server types:

•

SMTP without authentication

•

SMTP with authentication

•

POP-before-SMTP

These examples can be seen in Figure 3-6 . Required parameters for each SMTP configuration include:

•

SMTP server IP address

•

SMTP user name

•

SMTP user password

•

Device mail address

The device mail address specifies the sender’s email address for all log and alarm delivery emails.

31

SMTP servers often check only the sender’s host domain name of the email address for validity.

Consequently, the email address set for the device can use an arbitrary username with a registered hostname (i.e. [email protected]

or [email protected]) .

The SMTP user name and SMTP user password are required when either SMTP with authentication or POP-before-SMTP mode is selected.

Figure 3-5 SMTP Configurations

3.5. IP Filtering

Figure 3-6 SMTP mode selection in SMTP configuration

The Pro Series prevents unauthorized access using an IP address based filtering method. The users can allow one of the following scenarios by changing the parameter settings:

- Any host cannot access a specific service of the Pro Series

32

- Only one host of a specific IP address can access a specific service of the Pro Series

- Hosts on a specific subnet can access a specific service of the Pro Series

- Any host can access a specific service of the Pro Series

The IP filtering feature for access to Telnet console, SSH console, Web server or each port may be enabled or disabled. The factory default of the filtering feature is “All services and ports are accessible from any host”.

The meanings of each parameter in IP filtering configuration are as follows,

Interface

Apply IP filtering rule to the incoming packet of Pro Series. This is fixe parameter as eth0(Read-

Only).

Option and IP address/mask

Input field to describe a specific range of host on the network. The user may allow a host or a group of hosts to access the Pro Series. The user must then enter the IP address and subnet of access. Any user on a remote host must stay in the specified subnet boundary to access the

Pro Series. To allow only a specific host to access the Pro Series, enter the IP address of the specific host and just give 255.255.255.255 for the subnet with Normal option. To allow any hosts to have access to the Pro Series, give 0.0.0.0 for both of the IP address and subnet with

Normal option also. Refer to Table 3-2 for more details.

Service

Service which will be applied to the IP filtering rule. User can select one of Telnet, SSH, HTTP,

HTTPS or each serial port

Chain rule

Set the basic rule for the host to access the Pro Series as one of Accept or Drop.

33

Figure 3-7 IP filtering Configuration

The Pro Series also provide users with simple configuration way to block the specific services or serial ports from all hosts. If user set any service option as “Drop all”, then all access to the service from external will be blocked.

3.6. SYSLOG server configuration

The Pro Series supports a remote message logging service, SYSLOG service for the system and port data logging. To use the remote SYSLOG service, the user must specify the SYSLOG server’s IP address and the facility to be used. Figure 3-9 shows the SYSLOG server configuration page of the supplied Web interface.

Figure 3-9 SYSLOG server configuration

To receive log messages from the Pro Series, the SYSLOG server must be configured as “remote reception allowed”. If there is a firewall between the Pro Series and the SYSLOG server, there must be a rule that allows all outgoing and incoming UDP packets to travel across the firewall.

The Pro Series supports SYSLOG facilities from local0 to local7 . The user can employ these facilities to save messages from the Pro Series separately in the SYSLOG server.

35

If the SYSLOG service is enabled and the SYSLOG server configuration is properly set up, the user may configure the storage location for the system log or port data log of the Pro Series as

SYSLOG server. For more information about the configuration of port/system log storage location, please refer to section, 4.2.8

Port Logging and 5.2

System Logging.

3.7. NFS server configuration

The Pro Series supports NFS (Network File System) service for system or port data logging functions.

To use this service, the user must specify the IP address of a NFS server and the mounting path on the NFS server. Figure 3-10 shows the web based NFS server configuration page.

Figure 3-10 NFS server configuration

To store the Pro Series log data to the NFS server, the NFS server must be configured as “read and write allowed”. If there is a firewall between the Pro Series and the NFS server, there must be a rule that allows all outgoing and incoming packets to travel across the firewall.

If the NFS service is enabled and the NFS server configuration is properly set up, the user may configure the storage location for the system log or port data log of the If there is a firewall between the Pro Series and the SYSLOG server, there must be a rule that allows all outgoing and incoming

UDP packets to travel across the Pro Series as the NFS server. For more information about the configuration of the port/system log storage location, please refer to section, 4.2.8

Port Logging and

5.2

System Logging.

3.8. TCP service configuration

If a TCP session is established between two hosts, it should be closed (normally or abnormally) by either of the hosts to prevent the lock-up of the corresponding TCP port. To prevent this type of lock-

36

up situation, the Pro Series provides a TCP “keep-alive” feature. The Pro Series will send packets back and forth through the network periodically to confirm that the network is still alive. The corresponding TCP session is closed automatically if there’s no response from the remote host.

To use the TCP “keep-alive” feature with the Pro Series, the users should configure three parameters as follows:

TCP keep-alive time:

This represents the time interval between the last data transmission and keep-alive packet submissions by the Pro Series. These “keep-alive” messages are sent to the remote host to confirm that the session is still open. The default time value is 15 sec.

TCP “keep-alive” probes:

This represents how many “keep-alive” probes will be sent to the remote host, until it decides that the connection is dead. Multiplied with the “TCP ‘keep-alive’ intervals”, this gives the time that a link is forced to close after a “keep-alive” packet has been sent for the first time. The default is 3 times

TCP keep-alive intervals:

This represents the waiting period until a “keep-alive” packet is retransmitted due to no acknowledgement by the original Chinatown. The default value is 5 seconds.

By default, the Pro Series will send the keep-alive packets 3 times with 5 seconds interval after 15 seconds have elapsed since the time when there’s no data transmitted back and forth.

Figure 3-11 TCP keep-alive configuration

37

4. Serial Port Configuration

4.1. Overview

The serial port configuration capability allows the user to configure the host mode of each port, serial communication parameters, cryptography, port logging parameters and other related parameters.

The serial port’s host mode can be set as any of the following:

TCP :

The Pro Series operates as a TCP server and client. If the connection is not established, it accepts all incoming connections from any registered remote hosts and connects to the registered remote hosts if there is any data from the serial devices. Otherwise, it will send data back and forth. In summary, the Pro Series will work as if it is virtually connected to the remote host.

UDP :

The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.

Modem emulation :

Select this mode when the serial device already supports modem AT commands or users want to perform the session control by using AT commands. Only TCP session is supported.

With the port-logging feature while in console server mode, the data sent through the serial port is transferred to MEMORY or NFS server’s storage . The user can also define keywords for each serial port that will trigger an email or SNMP trap notification. This will enable the user to monitor the data from the attached device.

Using MEMORY to store data will result in loss of all information when the Pro Series is turned off.

Use the NFS server to preserve the serial port log data.

The serial ports can be configured individually or all at once. Table 4-1 summarizes the configuration parameters related to the serial port configuration.

Users can enter descriptive information for each port based on the device attached to it. This can include the device type, vendor, and/or location.

Figure 4-3 Port title configuration

4.2.3. Host Mode Configuration

The Pro Series operating mode is called the “host mode.” Three host modes are available: TCP mode ,

UDP mode, Modem emulation mode .

TCP mode

The Pro Series works as both TCP server and client. This mode works for most applications, since it will transfer the data either from serial port or from TCP port. If there is no connection established on a TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the registered remote hosts and redirects the data.

UDP mode

The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol.

Modem emulation mode

Select this mode when the serial device already supports modem AT commands or users want to perform the session control by using AT commands. Only TCP session is supported.

41

Figure 4-4 shows the main workspace screen for the host mode configuration.

Figure 4-4 Host mode configuration

4.2.3.1. TCP mode

For easier understanding of TCP modes, a simplified State Transition Diagram is often used. And to help users understand the diagram, the TCP state of the Pro Series is briefly described as follows.

- [Listen]

It represents “a waiting for a connection request from any registered remote host”. It is a default start-up mode when it is set as TCP mode.

- [Closed]

It means “no connection state”. If the data transfer between a remote host and the Pro Series is completed, the state is changed to this state as a result that either of the remote host or the Pro

Series sent a disconnection request. After this, the state is automatically changed to [Listen] mode.

- [Sync-Received]

The state is changed from [Listen] to [Sync-Received] if one of the remote hosts has sent a connection request. If the Pro Series accepts the request, the state is changed into [Established].

- [Sync-Sent]

42

If the Pro Series has sent a connection request to a remote host, the state is changed from

[Closed] to [Sync-Sent]. This state is maintained until the remote host accepts the connection request.

- [Established]

It represents “an open connection”. If one of the hosts, the remote host or the Pro Series, accepts a connection request from the other, the connection is opened and state is changed into

[Established].

- [Data]

When it is in [Established] state, data from a host will be transferred to the other one. For easier understanding of the TCP session operation, we called the state as [Data] state when actual data transfer is performed. Actually, the [Data] mode is a part of [Established] state as is described in the RFC 793 [Transmission Control Protocol]. This is a normal state for the data transfer phase of the connection.

The Pro Series works as either TCP server or client according to the situation. This will be the typical mode for most applications, since it will transfer the data either from serial port or from TCP port. The default TCP state is [Listen] which is the same as that of TCP server mode.

1) Typical State Transition

[Listen] --> [Sync-Received] --> [Established] --> [Data] --> [Closed] --> [Listen]

Or

[Listen] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed] --> [Listen]

The initial state is [Listen]. If there are data coming from the serial port, it will connect to the remote host as a TCP client and then transfer data through the TCP port. If there is incoming connection request from the remote host, it will accept the connection as a TCP server, and then transfer data through the serial port. Thus, users can assume that the Pro Series is always connected to the specified remote host.

2) Operations

Serial data transfer

Whenever the serial device sends data through the serial port of the Pro Series, data will be accumulated on the serial port buffer of the Pro Series. If the buffer is full or the time gap reaches the inter-character timeout (See Options in section 4.4 for details on inter-character timeout ), the

Pro Series connect to the registered remote host(s). If a TCP session has not been established yet. If the Pro Series succeeds in connecting to the remote host, the data in the serial port buffer will be transferred to the host. Otherwise, all the data stored in the buffer will be cleared.

Session disconnection

43

The connected session will be disconnected when the remote host sends disconnection request or when no data transfer activity is found through the serial port for certain amount of time, which is “ Inactivity timeout ” (See Options in section 4.4 for details on Inactivity timeout ). All the data remained in the serial port buffer will be cleared when it is disconnected.

Connection request from remote host

All the incoming TCP connection requests will be rejected in TCP client mode.

3) Parameters

TCP listening port

This is the TCP port number through which remote host can connect a TCP session, and, send and receive data. Incoming connection request to the ports other than TCP Listening Port will be rejected. The Pro Series does restrict the port number from 1024 to 65535 and if it is set as 0 only outgoing connection is permitted. (TCP server mode)

User authentication

If the User authentication options is enabled, user can access the port after entering correct user

ID and password. Please refer to the section 5.8 User administration for details of user management.

Telnet protocol

In TCP mode, Pro Series support Telnet Com Port Control Option (RFC2217 compliant) so that user can control serial parameters like baud rate, data bits and flow control option using his local

RFC2217-compliant Telnet client program. (Please refer to section 4.2.6 Serial port parameters for more detail information about serial parameters)

Usually this option is used with the RFC2217-compliant COM port redirector so that user can control parameters of serial ports of Pro Series using his serial port application program.

For this purpose, SENA OEM version of Serial/IP from Tactical Software, LLC is bundled with Pro

Series. Please refer to documentations of Serial/IP for more detail information about using the

COM port redirector. (Please refer to section Appendix 5 Using Pro Series with Serial/IP for more detail information)

Max. allowed connection

The Pro Series supports multiple connections from external host(s) to a serial port up to 32. But if there are remote host connections by the remote host list configuration already, possible number of connection is reduced to (Max. allowed connection - remote host(s) connected already). For example, if user set Max. allowed connection as 32 and if there are 3 connections from Pro Series to remote hosts, which are configured in the remote host list, then maximum number of connection from external hosts to a serial port will be reduced to 29 (=32 – 3). For more detail

44

information for remote host list configuration , please refer to 4.2.5 remote host list configuration section.

Cyclic Connection

If Cyclic Connection function is enabled, the Pro Series will make an attempt to connect to the user-defined remote host(s) at a given interval even if there’s no incoming serial data from the device connected to that serial port. If there is data on the remote host(s) to be sent to serial device, it can be transferred to the serial device via Pro Series’s serial port after the connection is established. Eventually, users can monitor the serial device periodically by making the remote host send the serial command to the Pro Series whenever it is connected to the remote host. This option is useful when users need to gather the device information periodically even if the serial device does not send its data periodically. Figure 4-6 shows the State Transition Diagram of the session operations in TCP mode.

Inactivity Timeout

When Inactivity Timeout function is enabled, connection between remote host(s) and Pro Series will be closed automatically if there is no data transmission during the value which is set in

Inactivity Timeout configuration.

4.2.3.2. UDP mode

The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol and only one pre-defined remote host is able to communicate with the Pro Series. Users do not have to

46

configure cyclic connection, since UDP is a connectionless protocol.

1) Operations

If a remote host sends a UDP datagram to the one of UDP Local port of the Pro Series, Pro Series first checks whether it is from one of the hosts configured on remote host configuration.

If the remote host is one of the hosts configured on remote host configuration , then Pro Series transfers the data through the serial port. Otherwise, the Pro Series discards the incoming UDP datagram. But user can force Pro

Series accept all incoming UDP datagram regardless remote host configuration by setting Accept UDP datagram from unlisted remote host parameter as ‘Yes’. If there is any incoming data from the serial port, the Pro Series transfers the data to the remote host defined on remote host configuration . If the remote port is not opened, the Pro Series will not transfer the data.

2) Parameters

UDP receiving port

The concept is the same as TCP listening port . See TCP mode parameters in the section 4.2.4.1 for details.

Max. allowed connection

The concept is the same as that of TCP communication. TCP mode parameters in the section

4.2.4.1 for details.

Accept UDP datagram from unlisted remote host

If Accept UDP datagram from unlisted remote host function is set as ‘No’, Pro Series will accept only incoming UDP datagram from the remote host(s) configured on remote host configuration .

On the contrary if Accept UDP datagram from unlisted remote host function is set as ‘Yes’, Pro

Series will accept all incoming UDP datagram regardless remote host configuration.

Send to recent unlisted remote host

If Send to recent unlisted remote host function is set as ‘Yes’, Pro Series sends data to the remote host, which has connected Pro Series recently. Recent unlisted remote host is a remote host, which has accessed a corresponding serial port of Pro Series but is not configured on remote host configuration. Surely, Pro Series also send data to the hosts, which are configured on remote host configuration. If Send to recent unlisted remote host function is set as ‘No’, Pro Series sends data only to the host(s) which are configured on remote host configuration. Pro Series maintains a recent unlisted remote host during the Inactivity Timeout .

Inactivity Timeout

In UDP mode, Inactivity Timeout is used in maintaining recent unlisted remote host. If there is no data transmission between unlisted remote host and serial port of Pro Series during Inactivity

47

Timeout, Pro Series will not send data from a serial port to the recent unlisted remote host again.

Namely, Inactivity Timeout in UDP mode is the time maintained recent unlisted remote host list by

Pro Series.

NOTE: If user set Inactivity Timeout as 0 in UDP mode, Pro Series does not allow any new connection from/to remote host if the number of current remote host exceeds Max. allowed connection .

4.2.3.3. Modem emulation mode

In modem emulation mode, the serial port process acts as if it is a modem attached to the serial device. It accepts AT modem commands and answers to them, as modems would do. It also handles the modem signals correctly. Modem emulation mode is useful in the following cases.

- There already exists a modem attached to the users’ serial device.

If users’ serial device already has a modem for phone-line connection, it can be just replaced by the Pro Series for Ethernet connection. What users need to do is to use an IP address (or domain name) and port number instead of phone number as a parameter of ATA/ATDT commands.

- It is required to send serial data to the multiple remote hosts.

If the serial device should send data to the multiple hosts, modem emulation mode is required.

For example, the first data from the serial device can be sent to the first data acquisition server and the second to the second server. What user device has to do is to change the IP address (or domain name) and port number parameters whenever the device sends ATD(T) XXX command.

By using the modem emulation mode of the Pro Series, users can have their serial device connected to the Ethernet network easily, which is cheaper than using phone line modem. Table 4-2 is a summarized AT command table which is supported by the Pro Series. Figure 4-6 shows the typical case of the serial port command flow when ATDA command is used to connect to the Ethernet network.

4.2.4. Remote host configuration

Remote host configuration is the list of hosts that will receive data from serial port of Pro Series when there is data transmission from a serial port of Pro Series.

In TCP mode, user can also configure secondary remote host(Backup host) that will receive data from serial port if Pro Series fails to connect to primary remote host. But if connection to primary remote host can be made, Pro Series dose not send data to secondary remote host until connection to primary remote host failed. And the maximum possible number of primary remote host is limited up to

4.

In UDP mode, user can configure only primary remote host because there is no way for Pro

50

Series to check status of primary remote host, so secondary remote host is meaningless.

The maximum number of remote host is limited up to 8 in the Pro Series. Figure 4-7 shows

Remote host configuration pages of the Web UI. (TCP mode)

Figure 4-7 Remote host configuration

4.2.5. Cryptography configuration

The Pro Series supports encrypted sessions for only TCP mode including modem emulation mode

(not UDP mode).

51

4-8 Cryptography configuration

4.2.5.1. Secure Sockets Layer(SSL) cryptography method

By setting the cryptography method as SSL, the Pro Series can communicate with other device supporting SSLv3 cryptography method in encrypted sessions.

SSL was developed by Netscape for use between clients and servers. SSL layers on top of any transport protocol and can run under application protocols such as HTTP. SSL aims to be secure, fast, and adaptable to other Web protocols. SSL provides data security for applications that communicate across networks. SSL is a transport-layer security protocol layered between application protocols and

TCP/IP.

To initiate SSL sessions, exchange of messages called the SSL handshake is required between two devices (Server and Client). The SSL protocol uses a combination of public-key and symmetric key encryption. Symmetric key encryption is much faster than public-key encryption, but public-key encryption provides better authentication techniques. The handshake allows the server to authenticate itself to the client using public-key techniques, and then allows the client and the server to cooperate in the creation of symmetric keys used for rapid encryption, decryption, and tamper detection during the session that follows. The details of handshake process step involved can be summarized as follows:

52

1. The client sends the server the client's SSL version number, cipher settings, randomly generated data, and other information the server needs to communicate with the client using

SSL.

2. The server sends the client the server's SSL version number, cipher settings, randomly generated data, and other information the client needs to communicate with the server over

SSL. The server also sends its own certificate and, if the client is requesting a server resource that requires client authentication, requests the client's certificate.

3. The client uses some of the information sent by the server to authenticate the server. If the server cannot be authenticated, the user is warned of the problem and informed that an encrypted and authenticated connection cannot be established. If the server can be successfully authenticated, the client goes on to next step.

4. Using all data generated in the handshake so far, the client (with the cooperation of the server, depending on the cipher being used) creates the premaster secret for the session, encrypts it with the server's public-key (obtained from the server's certificate, sent in step 2), and sends the encrypted premaster secret to the server. SSL differ in the way this "shared" master secret is created

5. If the server has requested client authentication (an optional step in the handshake), the client also signs another piece of data that is unique to this handshake and known by both the client and server. In this case the client sends both the signed data and the client's own certificate to the server along with the encrypted premaster secret.

6. If the server has requested client authentication, the server attempts to authenticate the client.

If the client cannot be authenticated, the session is terminated. if the client can be successfully authenticated, the server uses its private key to decrypt the premaster secret, then performs a series of steps (which the client also performs, starting from the same premaster secret) to generate the master secret.

7. Both the client and the server use the master secret to generate the session keys, which are symmetric keys used to encrypt and decrypt information exchanged during the SSL/TLS session and to verify its integrity--that is, to detect any changes in the data between the time it was sent and the time it is received over the SSL connection.

8. The client sends a message to the server informing it that future messages from the client will be encrypted with the session key. It then sends a separate (encrypted) message indicating that the client portion of the handshake is finished.

9. The server sends a message to the client informing it that future messages from the server will be encrypted with the session key. It then sends a separate (encrypted) message indicating that the server portion of the handshake is finished.

10. The SSL handshake is now complete, and the SSL session has begun. The client and the server use the session keys to encrypt and decrypt the data they send to each other and to validate its integrity.

Figure 4-9 Typical SSL Handshake Process

The Pro Series can act as a SSL server or as a SSL client depending on status of TCP mode. If TCP connection with SSL is initiated from remote host first, Pro Series acts as a SSL server during the SSL handshake process. On the contrary, if TCP connection with SSL is initiated from serial port of Pro

Series first, Pro Series acts as a SSL client during the SSL handshake process.

4.2.5.2. RC4 cryptography method

In RC4 cryptography mode, the Pro Series encrypt and decrypt all TCP stream using Key string. The

Pro Series can communicate each other via RC4 cryptography mode with same Key string.

54

4-10 RC4 Cryptography configuration

4.2.6. Serial port parameters

To connect the serial device to the Pro Series serial port, the serial port parameters of the Pro Series should match exactly to that of the serial device attached. The serial port parameters are required to match this serial communication. The parameters required for the serial communication are: UART type, baud rate, data bits, parity, stop bits, flow control DTR/DSR behavior and inter-character timeout.

UART type

First of all, the Pro Series and the serial device must agree on the serial communication type, which is one of RS232 mode, RS422/RS485 full mode or RS485 half mode. User can set the serial communication type by using DIP switch near by serial port. To change the serial communication type, change the position of each DIP switch as shown on Figure 4-11.

55

Figure 4-11 Serial communication type and DIP switch configuration

For more information about pin out of serial port and wiring diagram, please refer to Appendix

1 Connections section.

NOTE : Please turn off the power of the Pro Series device before changing the position of DIP switch. Changing the position of DIP switch while the power is on may cause a damage to the device.

Baud rate

The valid baud rate for the Pro Series is as follows:

75, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, and

230400

The factory default setting is 9600.

Data bits

Data bits can be between 7 bits and 8 bits. The factory default setting is 8 bits.

56

Figure 4-12 UART configuration

Parity

Parity can be none, even or odd . The factory default setting is none.

Stop bits

Stop bits can be between 1 bit and 2 bits. The factory default setting is 1 bit.

Flow control

The factory default setting of the flow control is None . Software Flow Control using XON/XOFF and hardware flow control using RTS/CTS are supported by the Pro Series.

Software flow control method controls data communication flow by sending special characters

XON/XOFF(0x11/0x13) between two connected devices. And hardware flow control method controls data communication flow by sending signals back and forth between two connected devices.

Note:

Flow control is supported only in RS232 and RS422 mode. RS485 mode does not support any kind of flow control method.

DTR/DSR behavior

The purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP

57

connection state by using serial port signal. The DTR is a write-only output signal, whereas the

DSR is a read-only input signal in the Pro Series side.

The DTR option can be set to one of three types: always high, always low or high when

TCP/UDP is opened . If the DTR behavior is set to high when TCP/UDP is opened , the state of the

DTR pin will be maintained high if the TCP/UDP connection is established.

The DSR input behavior can be set to one of two types: none or allow TCP/UDP connection only by high . If user sets the DSR input behavior as Allow TCP/UDP connection only by HIGH,

TCP connection to remote host from Pro Series is made only when the DSR status is changed from low to high. And TCP connection to remote host is disconnected when the DSR status is changed from high to low. And also Pro Series accepts TCP connection from the remote host only when the DSR status is high. In case of UDP mode, Pro Series receives UDP data from the remote host only when the DSR status is high. But In modem emulation mode, the connection to the remote host will be disconnected when the DSR status is changed from high to low regardless of the value of DSR behavior.

Serial device connected to Pro Series can control TCP/UDP connection of Pro Series by controlling DTR signal of it.

Note:

1. DTR/DSR behavior configuration will not be effective when the modem is enabled.

2. DTR/DSR behavior does not effective in RS422 and RS485 mode.

Inter-character timeout

This parameter defines the interval that the Pro Series fetches the overall serial data from its internal buffer. If there is incoming data through the serial port, the Pro Series stores data into the internal buffer. The Pro Series transfers data stored in the buffer via TCP/IP, only if the internal buffer is full or if the inter-character time interval reaches to the time specified as inter-character timeout . If inter-character timeout is set as 0, then data stored in the internal buffer will be transferred immediately without any delay.

Optimal inter-character timeout would be different according to your application but at least it must be larger than one character interval within specified baud rate. For example, assume that the serial port is set to 1200 bps, 8 Data bits, 1 stop bit, and no parity. In this case, the total number of bits to send a character is 10 bits and the time required to transfer one character is

10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.

Therefore, you have to set inter-character timeout to be larger than 8.3 ms. The inter-character timeout is specified in milliseconds.

58

4.2.7. Modem configuration

The Pro Series supports direct modem connection to the serial port of it. When user wants to connect modem to a serial port, he must configure Modem init-string and DCD behavior on modem configuration page. The Pro Series supports modem connection only when host mode is set as TCP mode .

Enable/Disable modem

By enabling this menu, user can attach a modem directly to the serial port of Pro Series. If this parameter is enabled, Pro Series considers this port will be used for modem use exclusively.

Modem init-string

User can specify modem initialization string for his modem in Modem init-string parameter. When a serial port is set as modem mode by setting Enable/Disable modem parameter as Enabled, Pro

Series sends modem initialization string to the serial port whenever rising edge of DTR pin is detected or parameter related with serial port configuration is changed.

DCD behavior

If DCD behavior is set as Allow TCP connection only by HIGH, Pro Series permits a connection from the remote host only when the DCD status of serial port is high. This feature is useful when user want to use a serial port only for dial-in modem mode. In this case, if there is no connection through modem already, Pro Series dose not permit TCP side connection.

Automatic release modem connection

If Automatic release modem connection is set as Enable, modem connection will be closed by Pro

Series if all TCP connections are closed once at least one TCP connection is opened. If this option is set as Disable, modem connection will not be closed by Pro Series even if all TCP connections are closed. Please note that actual phone line connection will be closed if one of modems closes connection, regardless of this option. That is, this option can be used for Pro

Series to disconnect modem connection by itself when all TCP connections are closed.

If user want to use dial-out function, he should set DCD behavior as None because he must be able to access modem connected to a serial port to send dial out command to the modem first.

59

Figure 4-13 Modem configuration

4.2.8. Port Logging

With the port logging feature, the data sent through the serial port is stored to MEMORY or a mounting point on an NFS server.

Enable/disable port logging

This parameter defines whether to enable or disable the port-logging feature. The factory default setting is [disabled].

Port log storage location

The port log data can be stored to the Pro Series internal memory the mounting point on an NFS server. If the internal memory is used to store port log data, the port log data will be cleared when the Pro Series is turned off. To preserve the serial port log data, set the storage location to be the

NFS server. To do this, the user must configure the NFS server in advance. Please refer to the

60

section 3.7 NFS server configuration for details of NFS server configuration.

Port log buffer size

This parameter defines the maximum amount of port log data to be logged. When using internal memory to store the log data, the total size of the port buffer cannot exceed 10 Kbytes.

When using an NFS server to store log data, the maximum port buffer size is unlimited. The user should configure the NFS server to ensure that the port logging system works properly.

Figure 4-14 Port logging configuration

4.2.9. Port event handling configurations

The Pro Series provides a user for a means of monitoring or reacting to data from serial device attached to a serial port of it through Port event handling configuration. Namely, user can define keywords for each serial port that will trigger the email/SNMP notification or command sent to the serial port directly on Port event handling configuration. And this will enable the user to monitor the data from the attached device or to manage/control a device attached serial port directly when predefined keywords are detected. At the same time, the status of the connection between the Pro Series and the serial device and the status of the TCP connection between the Pro Series and remote hosts could be monitored and managed in the same way of the port keywords as well.

Each reaction can be configured individually upon each event. Reaction can be an email delivery,

SNMP trap sending, command sending or either combination of all reactions.

Port event handling

If the user wants to enable port event handling feature, set Port event handling as enable. This is a global parameter so if this feature is disabled, the Pro Series does not take any actions on port

61

events.

Notification interval

To prevent Pro Series from being trapped in handling port event, there is a Notification interval parameter. Pro Series will send notification email or SNMP trap every Notification interval even it detect predefined keyword within Notification interval. The smaller value of this parameter will result in immediate response for predefined keyword and heavy usage of system resources. The largest value accepted by user is recommended to prevent system resource usage minimization.

NOTE: The port command in keyword response does not be affected by this parameter. Port command will be sent immediately when the corresponding keyword is detected.

Email notification

This parameter enables or disables Email notification feature of Pro Series. When Pro Series sends Email notification, it used SMTP server configured in SMTP server configuration. If the

SMTP server is not configured correctly or disabled, Email feature gets disabled also. For details of SMTP server configurations and descriptions, please refer to section 3.4

SMTP Configuration .

Subject of Email

This parameter set the subject of Email that will be sent by Pro Series when pre-defined keyword is detected.

Recipient's Email address

This parameter set mail recipient who will receive notification mail when pre-defined keyword is detected.

SNMP trap notification

This parameter enables or disables SNMP trap notification feature of Pro Series.

Subject of SNMP trap

This parameter set the subject of SNMP trap that will be sent by Pro Series when pre-defined keyword is detected.

62

Figure 4-15 Port event-handling configurations

SNMP trap receiver’s IP address

This parameter set IP address of SNMP trap receiver that will receive SNMP trap notification when pre-defined keyword is detected.

SNMP trap community

This parameter set a community that will be included in SNMP trap message when pre-defined keyword is detected.

SNMP trap version

This parameter set a version of SNMP trap, which will be sent when pre-defined keyword is detected.

63

Event keywords

The user can assign event keywords so that the Pro Series takes some actions such as sending email notification, sending SNMP trap notification or sending pre-defined command to a serial port if the keyword is detected at the serial port.

Event keyword

User can specify any words, which he/she wants to set as a keyword.

Email notification

User can select enable or disable for the Email notification action on keyword selected.

SNMP trap notification

User can select enable or disable for the SNMP trap notification action on keyword selected.

Port command

Pro Series supports direct reaction to a device attached to serial port when pre-defined keyword is detected. User can specify command or string, which will be sent to a serial port on this menu.

4.2.10. Copy port configuration

User can copy port configuration of one port to another ports. User can finish all port configuration conveniently using this function. There are two methods in copying port configuration. One is “Copy current port configuration to” specified ports and another is “Copy current port configuration from” specified port.

NOTE:

Port title, TCP port number and UDP port number are not copied by this function.

5. System Administration

The Pro Series display the system status and the log data via a Status Display Screen. This screen is to be used for management purposes. System status data includes the model name, serial number, firmware version and the network configuration of the Pro Series. The Pro Series can also be configured to deliver log data automatically via email to a specified recipient with the system-logging feature.

The users can configure the Pro Series’s device name, date and time settings, and reload factory default settings in this menu group. The users can also upgrade the firmware of the Pro Series using the web interface, remote consoles or serial console.

5.1. System Status

Figure 5-1 System status display

65

5.2. System Logging

The Pro Series provides both the system logging feature and the system log status display. The user may configure the Pro Series to enable or disable the system logging process, the system log buffer size, as well as select the log storage location.

System log storage location

The system log can be stored in the Pro Series internal memory , the mounting point on an

NFS server or the SYSLOG server . If the internal memory is used to store system log data, the log data will be cleared when the Pro Series is turned off. To preserve the system log data, set the storage location to be SYSLOG server or NFS server. To do this, the user must configure the corresponding media in advance. Unless the media is properly set up, the log will not be written to a specified storage location properly.

The Pro Series can also be configured to send log data automatically if the number of logs unsent reaches a pre-defined number. If enabled, the user must set parameters to initiate the creation of a email. These parameters would include the number of logs required to trigger an email, the recipient’s email address, etc. Figure 5-2 shows the configuration and system log view screen.

Figure 5-2 System log configuration and view

5.3. Change Password

The password for the administrative system user(root) of Pro Series can be changed using this menu.

This password is required when user wants to access serial console, telnet/ssh console or Web UI of

Pro Series. (Please refer to the section 5.8 User administration for details about port user management)

66

Figure 5-3 Changing the password

5.4. Device Name Configuration

The Pro Series has its own name for administrative purposes. Figure 5-4 shows the device name configuration screen. When user changes Device name, hostname of Pro Series will be also changed.

Figure 5-4 Device name configuration

Please note that user cannot set space character as one of device name. And If user sets blank as Device name then hostname is set as IP address of Pro Series automatically.

And also the device name is utilized for management program, HelloDevice Manager.

5.5. Date and Time Settings

The Pro Series maintains current date and time information. The PS410/810’s clock and calendar settings are backed up by internal battery power. (Please note that PS110 does not have a battery for internal clock. Current date and time setting will not be retained after system rebooting. So it is recommended to use NTP server to maintain correct date and time in PS110 model)

The user can change the current date and time, as shown in Figure 5-5 .

67

Figure 5-5 Date and time configuration

User also uses the NTP(Network Time Protocol) sever for setting the time of the Pro Series as shown in Figure 5-6 . If the NTP feature is enabled, the Pro Series will obtain the date and time information from the NTP server at each reboot. If the NTP server is set to 0.0.0.0, the Pro Series will use the default NTP servers. In this case, the Pro Series should be connected from the network to the

Internet. The user may also need to set the time offset from UTC depending on the users’ location.

Figure 5-6 NTP configuration

5.6. Factory Reset

The user may restore the factory default settings at any time using this menu. (User can also restore the factory default settings using the reset switch near by serial console port.)

Figure 5-7 Factory Reset

5.7. Firmware Upgrade

Firmware upgrades are available via serial, remote console or web interface. The latest upgrades are available on the Sena web site at http://www.sena.com/support/downloads/.

68

Figure 5-8 shows the firmware upgrade web interface.

To upgrade firmware via the web:

1. Select the latest firmware binary by clicking browse button.

2. Select and upload the selected version.

3. Once the upgrade has been completed, the system will reboot to apply the changes.

Figure 5-8 Firmware upgrade

To use either a remote or serial console to upgrade your firmware, the TELENT/SSH or terminal emulation program must support Zmodem transfer protocol. The previous settings will be retained after the firmware upgrade

To upgrade firmware via a remote console:

2. Connect the terminal emulation program using either TELENT/SSH or a serial console port.

Specifies the number of transmitted datagrams discarded. These are datagrams for which no problems were encountered to prevent their transmission to their destination, but which were discarded (for example, for lack of buffer space.) This counter would include datagrams counted in

Datagrams Forwarded if any such packets met this (discretionary) discard criterion.

OutNoRoutes :

Specifies the number of datagrams for which no route could be found to transmit them to the destination IP address. These datagrams were discarded. This counter includes any packets counted in Datagrams Forwarded that meet this "no route" criterion.

ReasmTimeout :

Specifies the amount of time allowed for all pieces of a fragmented datagram to arrive. If all pieces do not arrive within this time, the datagram is discarded.

ReasmReqds :

Specifies the number of datagrams that require reassembly.

ReasmOKs :

Specifies the number of datagrams that were successfully reassembled.

ReasmFails :

Specifies the number of datagrams that cannot be reassembled.

FragOKs :

Specifies the number of datagrams that were fragmented successfully.

FragFails :

Specifies the number of datagrams that need to be fragmented but couldn't be because the IP header specifies no fragmentation. For example, if the datagrams "Don't Fragment" flag was set, the datagram would not be fragmented. These datagrams are discarded.

FragCreates :

Specifies the number of fragments created.

7. CLI guide

7.1. Introduction

The root user can access the Linux console command line interface (CLI) of the Pro Series via the serial console or TELENT/SSH. In the CLI, the user can perform standard Linux commands to view the status of the Pro Series, edit the configuration, apply configuration changes.

7.2. Flash partition

The Pro Series internal flash is partitioned as shown in the table below. The user can access files at

/var directory at his own risk. Simply accessing these files will not affect the Pro Series after rebooting.

However, if the user invokes the command saveconf, the changes in the configuration file will be committed to the internal flash memory area of the Pro Series. This will result in the changes being kept after the reboot sequence. Invalid configuration changes can affect the Pro Series behavior. At worst, it may cause the Pro Series to be inoperable.

Appendix 4. Guide to the Bios menu program

A 4.1. Overview

The bios menu provides a way to recover the Pro Series unit using TFTP as a disaster recovery option and to diagnose the system hardware. If the user presses the <ESC> key within 3 seconds after the

Pro Series unit is powered up, he will enter the bios menu program. From this menu program, the user can set various system parameters, test system hardware, and perform firmware upgrades.

NOTE:

For PS110, the bios menu will be displayed only when the Data/Console switch is located at the

Console side.

A 4.2. Main menu

After entering the bios menu program, the user will see following main menu page:

A 4.4. Hardware test menu

Using the Hardware test menu, the user can test hardware components. There are three hardware test modes:

- One time

- Looping (without External test in Auto test)

- Looping (with External test in Auto test)

If the user selects One time , an auto test or each component test is performed just once. In this mode, the ping test to the remote host (server IP address) and UART test are also performed once.

If the user selects Looping (without External test in Auto test), the auto test is performed repeatedly until the user presses the <ctrl-c> keys. In this mode, the ping test to the remote host (server IP address) and UART test are not performed.

If the user selects Looping (with External test in Auto test)’, auto test is performed repeatedly until the user presses the <ctrl-c> keys. And, the ping test to the remote host (server IP address) and

UART test are also performed repeatedly.

Note:

To perform the test on the Ethernet and UART properly, the user must connect an Ethernet cable to the Ethernet port of the Pro Series and must plug the loopback connector to all the serial ports of the

Pro Series. There must exist a remote host with a valid IP address. The default server IP address is

92

192.168.0.128 and it can be changed using the [Firmware Upgrade] menu. Otherwise, the test may not be performed properly.
