5] SETTINGS AND MENUS
The TCP/IP module settings listed in the following sections can be configured using one or
both of these methods.
- “Configuring Via Serial Port” on page 5,
- “Configuring Via Serial Port” on page 5,
- “Configuring Via Web” on page 11.
Local IP Address
This is the Internet Protocol (IP) address of a device communicating on a LAN. Each TCP/
IP module must have a unique Local IP Address. The address entered must be recognized
by the LAN and must not be used by another device. A Local IP Address is entered as four
sets of three digits (000-255) separated by periods (i.e. 206.104.032.006). Speak to your
Network Administrator about obtaining an IP address.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)
The first time you set the module’s Local IP Address, you must do so using the serial port method
as described in “Configuring Via Serial Port” on page 5.
Local Port Number
The Local Port Number is assigned to the data transfer application program that
communicates through the TCP/IP module’s physical serial connector for initiating remote
connections with the LAN. Enter a value between 0 and 65535. Do not use Well-Known
Ports, which are port numbers used by everyone. For example, port 80 is used for HTTP
traffic (Web traffic). Speak to your Network Administrator about obtaining a port number.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)
Subnet Mask
Whenever the TCP/IP module wants to communicate with another device on the LAN, it will
compare its Local IP Address with that of the device. The result is then matched with the
assigned Subnet Mask number to determine
whether the device’s IP Address belongs to the same subnet (LAN segment) as the module.
If not, data will be directed towards the Gateway Address (see below) to redirect the data
to the correct subnet via a router. A Subnet Mask is entered as four sets of three digits
(000-255) separated by periods. A common Subnet Mask number is 255.255.000.000.
Speak to your Network Administrator about obtaining a Subnet Mask number.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)
Gateway Address
The Gateway Address enables the TCP/IP module to communicate with other LAN segments.
Enter the Local IP Address of the router connected to the same LAN segment as the TCP/
IP module. The Gateway Address must be within the local network. A Gateway Address is
entered as four sets of three digits (000-255) separated by periods (i.e. 206.104.032.006).

Serial Port: Yes (Menu [1], [2])
Web Page: Yes (Network Settings tab)
Baud Rate
This value represents the signalling rate of a line, which is the number of transitions
(voltage or frequency changes) that are made per second. It is important that you set the
Baud Rate to the same value as the serial device connected to the module. By default the
module is set to 19200. The TCP/IP module supports the following Baud Rates: 9600, 19200
and 38400.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (COM Settings tab)
Packets
A packet is a block of data received from the serial device connected to the TCP/IP module.
These settings define when the packet is sent to the LAN.
Serial Port: Yes (Menu [1], [2])
Web Page: Yes (COM Settings tab)
Packet Delay
If the idle period (no activity) between each character is equivalent to the programmed
Packet Delay, then the module sends the serial data currently in the buffer to the LAN. Enter
a value between 1 and 255ms. If you set the value to 0 this feature is disabled. The default
value is 3ms. The Packet Delay is directly related to the baud rate. When used with CDV
Group controllers, we recommend the following values:
If Baud Rate = 9600, set Packet Delay to 6ms
If Baud Rate = 19200, set Packet Delay to 3ms
If Baud Rate = 38400, set Packet Delay to 2ms
Packet Size
When the data received is equivalent in bytes to the programmed Packet Size, the module
sends the serial data in the buffer to the LAN. Enter a value between 1 and 458 bytes. If you
set the value to 0, this feature is disabled. The default value is 0 (disabled).
Acknowledgement Delay
When the TCP/IP module receives a packet from the LAN, it must acknowledge receipt,
otherwise the LAN continues to send the same packet. In order to save bandwidth, the
acknowledgement can be sent on the LAN with a packet received on its serial port. If, after
receiving a packet from the network, no data is received on the serial port, the module
sends the acknowledgment after the programmed Acknowledgment Delay. If data is
received on the serial port within the Acknowledgment Delay, the module ignores the delay
and waits until the entire packet is received. The acknowledgment will then be sent on the
LAN with the packet received on its serial port. Enter a value between 1 and 255ms. To send
the acknowledgement
as soon as a packet is received from the network, set the value to 1ms.
The default value is 100ms.
