CA-ETHR-A
TCP/IP Module
1] INTRODUCTION
The CA-ETHR-A TCP/IP module serves as an interface between a device that uses serial
communications (serial device) and a Local Area Network (LAN).
By connecting serial devices to the TCP/IP module, the serial devices can communicate with
other devices over a LAN using the IP protocol through a TCP data channel.
Although optimized for use with CDV Group products, this module can be used with other
serial devices. Below is a list of some types of serial devices that are supported:
- Centaur CT-V900-A controller
- Time and Attendance Clocks and Terminals
- Security and alarm systems
- CCTV equipment

2] CONFIGURING THE MODULE
Before using the TCP/IP module, you must configure it to communicate on a LAN. The
module can be configured by one of two methods:
- Using a commercial serial communication program, such as HyperTerminal, to access
the module’s serial port (refer to “Configuring Via Serial Port” below).
- Using a standard Web browser to access the module’s internal Web pages
(refer to “Configuring Via Web” on page 11).
To configure the module through its internal Web pages, you must first set the module’s
Local IP Address through its serial port.
Configuring Via Serial Port
To configure the module using a commercial serial communication program, such as
HyperTerminal, follow the steps detailed below. The first time you configure the module,
you must use this method. To configure the module using its internal Web pages,
refer to “Settings and Menus” on page 18.
Although these steps refer to HyperTerminal, you can use any serial communication
program that supports the same parameters.
Step A - “Hardware Connections” (page 6)
Step B - “Set up HyperTerminal” (page 6)
Step C - “Start Communication” (page 7)
Step D - “Configure the Module” (page 8)

Step A - Hardware Connections
To configure the TCP/IP module via its serial port, you must connect the module to a
computer’s COM port. Refer to Figure page 6 and to the instructions that follow:
Figure 3: Serial Communication
1) Apply 12Vdc to the terminals labeled 12V and GND on the TCP/IP module. Power can
be supplied from the auxiliary output of the serial device (i.e. controller) or from a
separate power supply.
2) Connect the DB-9 to modular phone jack cable between the modular phone jack
on the TCP/IP module and an available COM port on your computer.
Step B - Set up HyperTerminal
The first time you connect using this method you must set up HyperTerminal. If you have
already set up HyperTerminal, go to “Start Communication” on page 8.
1) Click Start, point to Programs, point to Accessories, point to Communications and then
click HyperTerminal.
2) The Connection Description dialog box appears.
In the Name text box, type a descriptive name such as Configuring TCP_IP Module.
Select the desired icon and click OK.

3) The Connect To dialog box appears.
From the Connect using list, select the COM port that the TCP/IP module is connected
to and click OK.
4) The COM Properties dialog box appears.
From the Bits per second list, select 19200. From the Data bits list, select 8. From the
Parity list, select None. From the Stop bits list, select 1. From the Flow control list,
select None. Click OK. All settings in the COM Properties dialog box must match the
TCP/IP module’s settings. If you modify the module’s settings after performing these
steps, make sure to edit HyperTerminal’s COM port settings.

5) The HyperTerminal window appears.
From the menu bar, click File and then click Save.
Step C - Start Communication
Once HyperTerminal is set up, you must establish communication between the TCP/IP
module and the computer.
1) Make sure the HyperTerminal window is open. If not, click Start, point to Programs, point
to Accessories, point to Communications, point to the HyperTerminal folder and select
the name created in Step B.
2) Press the Reset button on the TCP/IP module, wait two seconds and type the word
postech using your computer’s keyboard. If you wait more than 5 seconds after
pressing the Reset button, you will not be able to establish communication.
3) The TCP/IP module’s Main Menu appears.

Step D - Configure the Module
After accessing the TCP/IP module’s Main Menu, use the number keys on your computer’s
keyboard to access the different menus. If there is no activity for a period of 4 minutes, the
module exits its serial port menu.
For more detailed explanations of the different settings and menus, refer to “Settings and Menus”
on page 18.
1) From the Main Menu, press 1 on your computer’s keyboard to access the Configuration
Menu.
2) Press 2 on your computer’s keyboard to modify the module’s settings.

3) The module’s current values will appear one at a time. Type a new value and press
[ENTER] on your computer’s keyboard. If you want to keep the current value, press
[ENTER] without typing a value. Repeat these steps until all settings are programmed.
When finished, press the [SPACE] bar to exit this menu.
By default the serial port is 2. If you need to use the 5-pin serial connector (port 1)
to connect the TCP/IP to the serial device (refer to “Hardware Connections” on page
15), do not change the value of the serial port now. You will be able to select port
1 later, after accessing the module’s Web page. This allows you to make sure that
the module was configured properly and that you can access it through the Web.
4) Any modified settings must be saved.
From the Configuration Menu, press 3 on your computer’s keyboard.
5) Press 1 on your computer’s keyboard to save.
