IV.5

Configuration via Serial Mode or Telnet Port

Configure the unit so that it can communicate on a network with your serial device.

The WFS802b unit is configurable using a terminal program to access the serial port locally. Using this terminal program to respond to prompts is referred to as the Setup Mode. A Telnet connection may also be used to configure the unit over the network.

The unit’s configuration is stored in nonvolatile memory and is retained without power. You can change the configuration at any time. The unit performs a reset after the configuration has been changed and stored.

Note: The menus in this section show a typical device. Not all devices display information in the same manner.

Server Configuration

The unit’s basic server (i.e. network) values display upon selecting Server (option 0 from the

Change Setup menu). The following sections describe the configurable parameters within the

Copyright © Dr Robot Inc. 2005

98

Server configuration menu.

Set the IP Address

If DHCP is not used to assign IP addresses, enter it manually. The IP address must be set to a unique value in the network. Enter each octet and press Enter between each section inputted.

The current value is displayed in parentheses.

IP Address : ( 0) ( 0) ( 0) ( 0)

Set the Gateway IP Address

The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP address of the router connected to the same LAN segment as the unit. The gateway address must be within the local network.

The default is N (No), indicating the gateway address has not been set. To set the gateway address, type Y. At the prompt, enter the gateway address.

Set Gateway IP Address (N) ? Y

Gateway IP addr ( 0) ( 0) ( 0) ( 0)

Set the Netmask

A netmask defines the number of bits taken from the IP address that are assigned for the host part.

Netmask: Number of Bits for Host Part (0=default) (0)

The unit prompts for the number of host bits to be entered, then calculates the netmask, which displays in standard decimal-dot notation when the saved parameters are displayed (for example, 255.255.255.0).

Table IV.4 Standard IP Network Netmasks Representing Host Bits

Change Telnet Configuration Password

Setting the Telnet configuration password prevents unauthorized access to the setup menu via a Telnet connection to port 9999 or via web pages. The password must have

4 characters.

Change telnet config password (N) ?

An enhanced password setting (for Telnet access only) of 16 characters is available under

Note: A password is not required to access the Setup Mode window via a serial

connection.

DHCP Name

There are three methods for assigning DHCP names to the unit.

.

Default DHCP Name: If the DHCP name is not changed and the IP is 0.0.0.0, then the

DHCP name defaults to CXXXXXX (XXXXXX is the last 6 digits of the MAC address shown on the label on the bottom/side of the unit). For example, if the MAC address is 00-20-

4A-12-34-56, then the default DHCP name is C123456.

.

Custom DHCP Name: Create your own DHCP name. If using an IP address of 0.0.0.0, then the last option in Server configuration is Change DHCP device name. This option allows you to change the DHCP name to an alphanumeric name (LTX in the example).

Change DHCP device name (not set) ? (N)

Enter new DHCP device name : LTX

.

Numeric DHCP Name: Change the DHCP name by specifying the last octet of the IP address. When using this method, the DHCP name is LTXYY where YY is the last octet of the IP address. If the IP address specified is 0.0.0.12, then the DHCP name is LTX12.

This method only works with 2 digit numbers (0-99).

IV.5.3

Channel 1 and Channel 2 Configuration

Select option 1 Channel 1 or 2 Channel 2 from the Change Setup menu to define how the serial port responds to network and serial communications .

The following sections describe the configurable parameters within the Channel configuration menu.

Figure IV.5 Serial and Telnet Port Parameters

Baudrate

The unit and attached serial device, such as a modem, must agree on a speed or baud rate to use for the serial connection. Valid baud rates are 300, 600, 1200, 2400, 4800, 9600

(default), 19200, 38400, 57600, 115200, 230400, 460800, or 921600. The current value is displayed in parentheses.

Port Number

The Port No setting represents the source port number in TCP connections. It is the number that identifies the channel for remote initiating connections. The port number functions as the TCP/UDP source port number for outgoing packets. Packets sent to the

Copyright © Dr Robot Inc. 2005

101

unit with this port number are received to this channel. The port number selected is the

Incoming TCP/UDP port and Outgoing TCP/UDP source port.

Port No (10001) ?

The current value is displayed in parentheses. The default setting for Port 1 is 10001. The range is 1-65535, except for the following reserved port numbers:

Reserved (77F0h)

Note: It is recommended to not use the reserved port numbers for this setting as incorrect operation may result.

Use Port 0 for the outgoing local port to change with each connection. The port range is

50,000 to 59,999. Each subsequent connection increments the number by 1 (it wraps back around to 50,000).

Only use this automatic port increment feature to initiate a connection using TCP. Set the port to a non-zero value when the unit is in a passive mode or when using UDP instead of TCP.

Connect Mode

Connect Mode defines the unit’s connection method and its reaction to incoming connections over the network. The current value is displayed in parentheses.

Manual Connection Attempts to connect when directed by a command string received from the serial port. The first character of the command string must be a C (ASCII 0x43), and the last character must be either a carriage return (ASCII 0x0D) or a line feed (0x0A). No blanks or space characters may be in the command string. Between the first and last command string characters must be a full or partial destination IP address and

103

can include a destination port number.

The IP address must be in standard dot-decimal notation and may be a partial address, representing the least significant 1, 2, or 3 bytes of the remote IP address. The period is required between each pair of IP address numbers.

If present, the port number must follow the IP address, must be presented as a decimal number in the range 1-65535, and must be preceded by a forward slash (ASCII 0x2F). The slash separates the IP address and the port number. If you omit the port number from a command string, the internally stored remote port number starts a connection.

If a partial IP address is presented in a command string, it is interpreted to be the least significant bytes of the IP address and uses the internally stored remote IP address to provide the most significant bytes of the IP address. If the IP address entered is 0.0.0.0/0, the device server enters Monitor Mode.

For example, if the remote IP address already configured in the unit is 129.1.2.3, then an example command string would be

C3/7. (This would connect to 129.1.2.3 and port 7.) You may also use a different ending for the connection string. For example, C50.1/23 would connect you to 129.1.50.1 and port

Hostlist If this option is set to True, the device server scrolls through the host list until it connects to the first available device listed in the host list table. Once it connects, the unit stops further attempts. If this connection fails, the unit continues to scroll through the table until it is able to connect to the next available IP address in the host list.

Hostlist supports a minimum of 1 and a maximum of 12 entries. Each entry contains the IP address and the port number.

c) Datagram Type

Directed UDP When selecting this option, the prompt requests the Datagram type. Enter 01 for directed or broadcast UDP.

When the UDP option is in effect, the unit uses UDP datagrams to send and receive data.

d) Modem Mode

In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device.

It accepts AT-style modem commands, and handles the modem signals correctly.

Copyright © Dr Robot Inc. 2005

105

Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with WFS802bs, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character response).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network

TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1-character response).

Without Echo In Modem Mode, echo refers to the echo of all of the characters entered in command mode; it does echo data that is transferred. Quiet Mode (without echo) refers to the modem

When an active connection is in effect, the unit transfers data and does not process commands received from the serial interface.

When a connection is terminated or lost, the unit reverts to command mode. When an active connection is in effect, the unit terminates the connection if it receives the following sequence from the attached serial device:

.

No serial data is received for one second.

.

The character sequence +++ is received, with no more than one second between each two characters.

.

No serial data is received for one second after the last + character. At this time, the unit responds affirmatively per the selected echo/response mode.

.

The character string ATH is received, terminated with a carriage return. The unit responds affirmatively according to the selected echo/response mode and drops the network connection. The serial interface reverts to accepting command strings.

If this sequence is not followed, the unit remains in data transfer mode.

(6) When modem_control_in transitions from a high state to a low state, the network connection to or from the serial port drops.

Flush Mode

The FlushMode (buffer flushing) parameter controls line handling and network buffers with connection startup and disconnect.

FlushMode ( 0) ?

Select between two different packing algorithms (the current configuration is displayed within the parentheses). Available Flush Mode options are:

Table IV.14 Flush Mode Options

Input Buffer (Serial to Network)

Pack Control

The packing algorithm defines how and when packets are sent to the network. The standard algorithm is optimized for applications in which the unit is used in a local environment. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN).

Adjusting parameters in this mode can economize the network data stream. Pack control settings are enabled in Flush Mode. Set this value to 00 if specific functions are not needed.

Packing Interval:

Packing Interval defines how long the unit should wait before sending accumulated characters. This wait period is between successive network segments containing data. For alternate packing, the default interval is 12 ms.

Trailing Characters:

In some applications, CRC, Checksum, or other trailing characters follow the end-of-sequence character; this option helps to adapt frame transmission to the frame boundary.

Send Characters:

.

If 2-Byte Send Character Sequence is enabled, the unit interprets the sendchars as a

2-byte sequence; if this option is not enabled, the unit interprets them independently.

.

If Send Immediately After Characters is not set, any characters already in the serial buffer are included in the transmission after a "transmit" condition is found. If this option is set, the unit sends immediately after recognizing the transmit condition

(sendchar or timeout).

Note: A transmission might occur if status information needs to be exchanged or an acknowledgment needs to be sent.

DisConnTime (Inactivity Timeout)

Use this parameter to set an inactivity timeout. The unit drops the connection if there is no activity on the serial line before the set time expires. Enter time in the format mm:ss, where m is the number of minutes and s is the number of seconds.

DisConnTime (0: 0) ?:

To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds

(99 minutes, 59 seconds). The default is 0.

SendChar 1 and SendChar2

Enter up to two characters in hexadecimal representation

SendChar 1 ( 0) ?

SendChar 2 ( 0) ?

If the unit receives a character on the serial line that matches one of these characters, it sends the character immediately, along with any awaiting characters, to the TCP connection.

This action minimizes the response time for specific protocol characters on the serial line

(for example, ETX, EOT). Setting the first SendChar to 00 disables the recognition of the characters. Alternatively, the unit can interpret two characters as a sequence.

Telnet Terminal Type

Copyright © Dr Robot Inc. 2005

110

This parameter displays only if the terminal type option is enabled in Disconnect Mode. If this option is enabled, use the terminal name for the Telnet terminal type. Enter only one name.

If the terminal type option is enabled, the unit also reacts to the EOR (end of record) and binary options, which can be used for applications such as terminal emulation to UNIX hosts.

Channel (Port) Password

This parameter appears only if the channel (port) password option is enabled in Disconnect

Mode. If the option is enabled, set a password on the serial port.

WLAN Settings

Without adequate protection, a wireless LAN is susceptible to access by unauthorized users. As such, WFS802b includes the Wired Equivalent Privacy (WEP) encryption standard as an additional means of security.

To modify WLAN and WEP settings, select 4 WLAN from the Change Setup menu.

Enable WLAN

The current value is displayed in parentheses. By default, WLAN is enabled on WFS802b.

Enable WLAN (Y) ?

Find Network Name

Enter the name of the network in which the WFS802b unit resides. The current value is displayed in parentheses.

Find network name (DRI_IBSS) ?

Enable Ad Hoc Network Creation

The current value is displayed in parentheses. By default, Ad Hoc network creation is enabled on WFS802b.

Enable Ad Hoc network creation (Y) ?

Name (DRI_IBSS) ?

Country 0=US, 1=FR, 2=JP, 3=Other (0) ?

Channel (11) ?

Enter Y to enable Ad Hoc network creation and display configurable parameters:

1. At the Name prompt, enter the network name as text and hit Enter. The default name displays in parentheses.

2. Select a Country by entering 0, 1, or 3. By default, 0 (United States) is selected. Press

Security

As an additional security measure, enable WEP on the WFS802b. The current value is displayed in parentheses. By default, WEP is disabled on WFS802b.

Security 0=none, 1=WEP (0) ?

Data Rate

WFS802b permits the control of the transmission rate. The default is a data rate up to

11Mbps. The current value is displayed in parentheses.

Data rate, Only : 0=1, 1=2, 2=5.5, 3=11 Mbps or

Up to: 4=2, 5=5.5, 6=11 Mbps (6) ?

Power Management

Power management reduces the overall power consumption of the WFS802b unit. Enabling power management increases the response time. The current value is displayed in parentheses.

Enable power management (N) ?

Expert Settings

Note: Change these settings via Telnet or serial connections only.

Caution: Only an expert should change these parameters. These changes hold serious consequences.

TCP Keepalive Time

TCP Keepalive time defines how many seconds the unit waits during a silent connection before checking whether the currently connected network device is still on the network. If the unit does not receive a response, it drops that connection.

TCP Keepalive time in s (1s – 65s; 0s=disable): (45)?

ARP Cache Timeout

When the unit communicates with another device on the network, it adds an entry into its ARP table. ARP Cache timeout defines the number of seconds (1-600) the unit waits before timing out this table.

ARP Cache timeout in s (1s – 65s; 0s=disable): (600)?

IV.5.7

Security Settings

Note: As recommended, set security over the dedicated network or over the serial setup. If the parameters are set over the network (Telnet 9999), someone else could capture these settings.

Caution: Disabling both Telnet Setup and Port 77FE prevent users from accessing the setup menu from the network.
