Introduction
The Aport-31x Ethernet serial server connects RS-232, 422, 485 serial devices to an
Ethernet LAN/WAN providing a reliable communication connection. Existing
Windows based serial software using standard Windows API does not have to be
modified to communicate over an Ethernet LAN to a serial device. The Aport-31x
virtual COM port will make this an easy transition.
The Aport-31x operates in “Direct IP Mode”, “Virtual COM Mode”, and “Paired
Mode”. The Aport-311 has one asynchronous DB-9 serial port and Aport-312 has two
asynchronous DB-9 serial ports, they all have one 10/100 Mbps Ethernet RJ-45
connection. The Ethernet port will auto-select 10BaseT or 100BaseTX.
The Aport-31x Windows driver installs virtual COM ports in the Device Manager of
the operating system. The virtual COM port is designed to establish a connection with
the Aport-31x. This in turn will allow communications with the connected serial
device in the same manner as a device connected to the COM port on a PC. The LAN
becomes transparent to the serial device and the software running on the PC.
The Aport-31x can be configured as a TCP or UDP Client/Server. In direct IP and
virtual COM modes, Aport-31x should be configured as a server. Aport-31x also
offers a Heart Beat feature to insure a reliable communications connection.

Communication Modes
The Aport-31x allows serial devices to communicate over a LAN or Intranet network.
Serial devices are no longer limited to a physical connection to the PC COM port.
They can be installed anywhere on the LAN using TCP/IP or UDP/IP
communications. This will also allow traditional PC COM ports access to a serial
device anywhere on the LAN network.
2.1
Direct IP Mode
Direct IP connections allow applications using TCP/IP or UDP/IP network socket
programs to communicate with the asynchronous serial port on the Aport-31x. In this
type of application the Aport-31x is configured to TCP or UDP server. The socket
program running on the PC establishes a communication connection with the Aport31x. The raw data is sent directly to and from the serial port.
2.2
Virtual COM Mode
The Virtual COM mode requires the installation of a driver. When installed a new
COM port is added to the Device Manager. Windows programs using standard
Windows API calls will be able to interface with Virtual ports. The PC will act as the
host connecting to the Aport-31x when the program opens the virtual COM port.

Serial
Aport-31x
IP101S
Serial Device
Once the connection is made, the LAN is transparent to the serial device. Applications
work just as if the serial device is connected a host’s physical COM port. The virtual
COM port converts the application’s data into IP packet destined for the Aport-31x,
which in turn converts the IP packet back to serial data.
In this mode, the Aport-31x must be set to either TCP/server or UDP/server in the
menu with a designated communication port number. The virtual COM driver is a
TCP or UDP client.

Aport-31x Manual
2.3
Paired Mode
Paired mode is also called serial tunneling. When this type of configuration is selected
additional software will not have to be loaded on a host PC. In fact a PC is not
required to make the connection. Any two dumb serial devices that can communicate
with each other through a serial link will be able to communicate using two Aport31xs and the LAN.
Two Aport-31xs are configured with one setup as a TCP or UDP client and the other
to TCP/UDP server. When setting up the Server, the Remote IP address section must
contain the address of the Client. This will allow the Client’s IP address to pass the IP
address-filtering feature of the Server. Conversely, the Remote IP address of the
Client must contain the Server’s IP address.

Heart Beat
The Aport-31x provides a convenient way to establish reliable communications
between two devices. Communication port 5300 is reserved for the Heartbeat Protocol.
Without this feature a device that loses a connection and stops communicating would
not be able to reconnect without personally attending to the problem. A TCP data
connection can be lost when there is a power failure or temporary loss of an Ethernet
connection on either the client or server.
If a loss occurs the Heart Beat feature will try to reconnect the TCP data connection
every 5 seconds until communications is established again. The Heart Beat feature is
available to use with the Virtual COM Mode, Paired Mode and Direct IP Mode. This
is not available when using a UDP application.

Making the Hardware Connections
The following information is provided to give the user an understanding of how to
connect the Aport-31x to the LAN and serial device. A review of the switch settings
and the functionality of the LED’s are also provided.
3.1
Serial Connection
The Aport-31x has one, two or four DB-9 male connectors. The serial port is
configured as a DTE (data terminal equipment) device. All PC COM ports are DTE
ports. A null modem cable is required to make a connection between the COM port on
a PC and the Aport-31x serial port. A straight through cable is required to connect the
Aport-31x serial port to a DCE device.
3.2
Power Connection
The Aport-31x has a two pins terminal block and power jack. Power can apply on
either terminal block or the power jack. It accepts 9VDC-15VDC 500mA power
supply. When power is apply a green light label as run will flash every one second to
indicate the system is up and running.
3.3
Ethernet Connection
A straight-through Ethernet cable can be used to connect the serial server to an
Ethernet hub, switch, or wall plate. A crossover Ethernet cable can be used to make a
connection directly to the NIC (Network Interface Card) on a PC or laptop.
3.4
Reset Button
The reset button can be found between the switch and terminal block. To reset the unit
manually apply power, insert a small plastic tool, and press lightly depressing switch.
Hold for 3 seconds and release. The Link and Run light will go out and turn back on.

Data
When all these switches are moved into the ON position, the Aport-311/ Aport-312
enters Console Mode, allowing configuration of the Aport-311/ Aport-312 from a PC
running a terminal program such as HyperTerminal. When the Aport-311/ Aport-312
enters Console Mode, the Console Mode screen will appear in the HyperTerminal
program window. The serial port settings must be 8-N-1 at 19200 baud.
When the DIP switches are switched to the ON OFF position, the Aport-311/Aport312 will work at Loop back Mode, all data is sent back immediately.
When the DIP switches are switched to the OFF ON position, the Aport-311/Aport312 will revert to its factory version firmware no matter what newer firmware has
been upgraded.
When all of the DIP switches are switched back to the OFF position, the Aport311/Aport-312 will enter Data Mode (RS-232, RS-422 or RS-485).
3.7
Serial Ports
The Aport-311 has one serial port. The port can be configured as a Console Mode
connection or as RS-232, RS-422 or RS-485 interface to the Aport-311 (if all of the
DIP switches are in the OFF position) using the Manager software, via Telnet, or
using the Web Server.
The Aport-312 has two serial ports. Port 1 operates the same as the Aport-311 serial
port. Port 2 on the Aport-312 is a RS-232 only interface.
The RS-232 interfaces are configured as DTEs (Data Terminal Equipment). The
connectors for all ports are DB-9M.
3.8
Serial Server/Port Operational Modes
Aport-31x Manual
7
Using the Manager software, the Aport-31x serial server can be put into Console
Mode, Default Mode or Upgrade Mode. The serial ports can be configured for RS-232,
RS-422 or RS-485 operation. The Aport-311/ Aport-312 serial server also can be put
into Console Mode by placing all the DIP switches into the ON position.
3.8.1
Console Mode
The console mode allows access to the Aport-31x setup menu. This is one way to
reconfigure the default settings for the application. A serial connection is made
between a COM port on the PC and the Aport-31x serial port 1 with a null modem
cable. In console mode, the serial port defaults to an RS-232 interface.
The Aport-31x serial port default settings are, baud rate 19200, 8 data bits, no parity,
and 1 stop bit. Hyper Terminal should be used for this type of setup. Hyper Terminal’s
serial settings are configured the same as the mentioned default settings of the Aport31x and must be set to VT100 emulation mode. The default settings are used only if
they have not been changed.
See Chapter 10 for details.
3.8.2
Upgrade Mode
The newest firmware can be installed on the Aport-31x using the PC’s serial port or
the Virtual COM port.
See Chapter 13 for details.
3.8.3
Default Mode
When Default Mode is selected and the Server Properties are updated (saved), all
configuration settings return to their default values.
3.8.4
RS-232 Mode
The RS-232 supports 8 channels plus Signal Ground and is configured as DTE like a
computer. Signals are single ended and referenced to Ground. To use handshaking,
Flow Control must be set to RTS/CTS during Configuration. Refer to the Pin out
table for connections.
3.8.5
RS-422 Mode
The RS-422 mode supports 4 channels with full duplex operation for Receive,
Transmit, RTS (Request To Send) and CTS (Clear To Send). The data lines are in
differential pairs. Ground provides a common mode reference. To use handshaking
8
Aport-31x Manual
Flow Control must be set to RTS/CTS during configuration. Refer to the Pin out table
for connections.
3.8.6
RS-485 Mode
The RS-485 mode supports the Transmit and Receive Channels using 2-wire halfduplex operation. The data lines are differential pair Ground provides a common
mode reference. Refer to the Pin out table for connections.
RS-485 Receiver Biasing can be implemented from the Aport-31x serial server if the
network does not supply it. Remove the two side-cover screws of the serial server,
slide the cover off and re-position the bias jumpers to enable biasing (shorting).

Server Properties
There are four ways to access the Server Properties and program the Aport-31x:
Manager software, Console mode, Telnet or Web Server.
Instructions on how to move around in the user interface and change settings pertains
to the Manager software but are similar in others.
6.1
Server Name
The server name is user configurable. It is recommended users with more than one
Aport-31x connected to the LAN assign a new name to each. When the Manager
software searches for servers on the LAN it will display the server name allowing the
user to distinguish between Aport-31xs.
6.2
Serial Number
Each Aport-31x has a unique serial number. This is fixed and cannot be changed.
6.3
Password
Entering a password activates a security feature on the serial server. Once a password
is entered it will be required to access the menu and make changes.
6.4
DHCP
DHCP servers are a part of numerous LAN management systems. The DHCP field
has two selections, “Enable” or “Disable”. Arrow to the desired selection and select
enter.
16
Aport-31x Manual
When enabled, Aport-31x will send a DHCP request to the DHCP server, which will
assign a dynamic IP address, netmask, and gateway to the Aport-31x. If a DHCP
server is not available on the network the Aport-31x will time out after 10 seconds and
the default values will remain. When DHCP is enabled, the IP address, Netmask and
Gateway fields become inaccessible and cannot be changed by the user.
6.5
IP Address
A static IP address can also be assigned in this section of the menu. A dynamic
address assigned by the DHCP server may change if the Aport-31x looses the Ethernet
connection or power is removed. The host (client) communication software requests a
connection to the specific IP address of the serial server. If the DHCP reassigns a
different IP address the software will not be able to communicate with the hardware. It
is recommended to use a static IP address.
A static IP address is permanent and will not change unless changed in the menu. In
most cases the network administrator establishes the static address to be used.
6.6
Netmask
The default LAN netmask is configured for a Class C address. This maybe
reconfigured by the user.
6.7
Gateway
The gateway IP address allows users to access the serial server from outside the LAN.
6.8
MAC Address
The MAC address is not adjustable. This is assigned in the factory. Every Ethernet
device manufactured has it own unique MAC address.
6.9
Version & Date
The currently loaded version of the firmware, and when it was released, are shown
here.
6.10 Link Status
Link status automatically displays the type of Ethernet connection. It will either
display 10 BaseT or 100BaseTX in full duplex or half duplex. This will depend on the
LAN, switches, hubs used in the LAN topology.
Aport-31x Manual
17
6.11 Server Serial Port
This field indicates the number of the port for with serial server properties are
currently being displayed. Changing the number in this field will cause all the other
fields to display the properties for the specified port. Note, however, that before
changing ports, any change to properties must be Updated (Saved) or the serial server
will not retain them.
6.12 Baud Rate
The serial port baud rate on the Aport-31x must match the serial baud rate of the
connected device unless using Virtual COM mode. In Virtual COM mode the
software program will establish serial settings.
6.13 Data/Parity/Stop
This setting will have to match the data format of the connected device unless using
Virtual COM mode. In Virtual COM mode the software program will establish serial
settings.
6.14 Flow Control
The flow control setting must match the connected serial device unless using Virtual
COM mode. In Virtual COM mode the software program will establish serial settings.
6.15 Protocol
Select TCP or UDP protocol. If the application does not require a UDP connection,
select TCP. TCP guarantees reliable communication with error checking whereas
UDP provides faster transmission.
When UDP mode is chosen the Serial timeout, TCP alive timeout, Connection mode,
Connection at, Maximum connection and Remote IP address fields are replaced with
the following three fields: Destination IP address range, Port number and Source IP
address range. In this mode the server can be configured to broadcast data to and
receive data from multiple IP addresses. Four IP address range fields are provided.
18
Aport-31x Manual
6.16 Serial Timeout
Default is 0, or no timeout. Setting timeout to any value between 1 and 65535 seconds
activates it. If communications are idle for specified timeout value the serial server
will reset and make itself available for another connection.
6.17 TCP Alive Timeout
This monitors TCP activity. If TCP activity stops for the length of time specified in
this field the connection will be closed. This field can be set to any value between 0
and 255 minutes. If zero, or no value, is entered into this field the server will not
disconnect.
6.18 Connection Mode
The Connection mode field has three options, Server, Client and Client (no heartbeat).
When Client or Client (no heartbeat) is selected, the Connection at field automatically
becomes active (allowing the user to select Power up or Data arrival).
• When using the Virtual COM Port feature, select Server.
• When using a TCP or UDP Socket program, select Server.

6.19 Delimiter HEX1 and Delimiter HEX 2
Aport-31x Manual
19
These two fields allow the user to enter two ASCII characters (in hex format) that
delimit the beginning and end of a message. When a message with both these
delimiters is received at the serial port, the data contained in the serial buffer is placed
in an Ethernet packet and sent out the Ethernet port. If only Delimiter 1 is set
(Delimiter 2 is zero or blank), upon receiving Delimiter 1 the Aport-31x will put all
the data in the serial buffer in an Ethernet packet and send it out the Ethernet port. If
serial data greater than 1 kilobyte is received it will automatically be placed in an
Ethernet packet and sent out the Ethernet port.
6.20 Force Transmit
This field allows the user to set a maximum time limit between transmissions of data.
The value set in this field multiplied by 100 ms determines the Force Transmit time.
When the elapsed time reaches the time configured in this field, the TCP/IP protocol
will pack the data currently in the serial buffer into a packet and send it out the
Ethernet port.
6.21 Port Status
This field indicates whether a serial port is connected to a server or by a client.
6.22 TCP/UDP Port
The TCP/UDP Port defines a communication port number. In all modes of operating,
Virtual COM, Direct IP, and Paired modes, both the TCP/UDP Client and server port
settings must match.
For example the Virtual COM default setting TCP/UDP Port # 4000. If the port # of
the Aport-31x is changed to 4001, the Virtual COM TCP/UDP Port will have to be
changed to 4001.
6.23 Serial Port Mode
This allows configuration of the serial server for the following modes of operation:
•
•
20
Console – When this mode is selected and the server is updated, a PC
running a communication program such as HyperTerminal can communicate
with the serial server via the Console Mode serial port (Port 1 on Aport-31x),
displaying the Server Properties screen and allowing configuration of the
server and its ports.
Upgrade – When this mode is selected and the server is updated, firmware
can be uploaded into the serial server via the Console Mode serial port or a
virtual COM port mapped to the number of the Console Mode serial port.
Aport-31x Manual
•
•
•
•
Default – When this mode is selected and the server is updated, it will revert
the server to its default configuration.
RS-232 – When this mode is selected and the server is updated, the selected
serial port will become a RS-232 serial port on the server.
RS-422 – When this mode is selected and the server is updated, the selected
serial port will become a RS-422 serial port on the server.
RS-485 – When this mode is selected and the server is updated, the selected
serial port will become a RS-485 serial port on the server.
6.24 Connection At
When the Connection Mode field is set to Client or Client (no heartbeat), this field
becomes active, allowing the Aport-31x (acting as a client) to connect to the server
either on Power up or on Data Arrival (first character arriving).
6.25 Maximum Connection
This field allows the user to configure the Serial Server to have up to eight TCP
connections.
6.26 Remote IP Address
This is a security feature that is activated when the IP address of the desired client is
programmed into the remote IP Address setting of the menu. This tells the Aport-31x
to communicate with only the listed IP address and to filter out all other requests for
connection. The Aport-31x is setup in the menu as a TCP or UDP server to us this
feature.
The default setting is 255.255.255.255. It is recommended not to change this setting
until the application has been tested and is communicating properly. At that point the
address filtering feature of the Aport-31x can be activated.
6.27 Update/Save
Server properties must be updated separately for each serial port. Updating varies
slightly depending on which of the four configuration user interfaces are used.
6.27.1 Updating the Server Properties in Manager Software
From the Server Properties screen, click the Update button to store the configuration
settings for the currently selected port. The vcomui dialogue box will appear

14 Troubleshooting
Q: Why sometimes HyperTerminal loses characters or display funny characters?
A: This happens when you open a new HyperTerminal connection and keep inputting
the same character. The reason is before HyperTerminal receiving two different
characters from the other end, its status is Auto detect, and your port settings haven’t
fully take effect, so the transferred data is not predicable. To solve this problem, input
two different characters from the other end, then the HyperTerminal status will show
your port settings such as 19200 8-N-1, save this HyperTerminal connection. Next
you open your saved HyperTerminal connection, everything will be fine.
Q: What should I do when I forget the IP address or baud rate setting of a Aport-31x?
A: You can use the searching capability to get the information of all Aport-31x on the
network. Double clicks on the searched result will show the detail configuration
parameters of the device.
Q: Why I cannot open virtual COMx?
A: The server settings and virtual COMx settings may not match, please make sure
their IP address, protocol, port and flow control mode are the same, and the remote IP
address should be the host IP address. Besides the Aport-31x cannot be at Console
mode.
Q: Why the arrow keys of HyperTerminal in Windows 2000 do not work in Console
mode and telnet?
A: Please download new version of HyperTerminal. The HyperTerminal comes with
Windows 2000 does not send the arrow key code properly.
