Pin Assignments

Booting the tM-Series in Init Mode
Make sure the switch is placed in the “Init” position. Connecting to the PC and the Power Supply
The TM-Series series is equipped with an RS-485 port for connection to a 232/USB converter to a PC

Installing the DCON Utility
The DCON Utility is an easy-to-use tool designed to enable the simple configuration of I/O modules that use the DCON protocol.

Step 1: Locate the DCON Utility

The DCON utility can be obtained from the companion CD or from the ICPDAS FTP site:
ftp://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_utility/
CD:\Napdos\Driver\DCON_Utility

Using the DCON Utility to Initialize the TM-Series Module

The M-Series is an I/O module based on the DCON protocol, meaning that you can use the DCON Utility to easily initialize it.

Step 1: Run the DCON Utility_Pro

Step 2: Use the COM1 port to communicate with the TM-Series

Click the “COM Port” option from the menu and a dialog box will be displayed that will allow you to set the communication parameters as described in the table below.

Communication parameter	Factory default Value
Address	0
Baud Rate	9600
Protocol	DCON
Checksum	Disabled
Parity	N,8,1

Step 3: Search for the tM-Series module

Click the “Start Search” button from the toolbox to search for the tM-Series module.
After the TM-Series module is displayed in the list, click the “Stop Search” button.

Step 4: Connect to the TM-Series
After clicking on the name of the module in the list, a dialog box will be displayed.

Step 5: Initialize the TM-Series module
Set the “Address” field in the dialog box to 1 and then click the “Setting Module Configurations ” button to save the settings.

Rebooting the TM-SeriesModule in Normal Mode
Make sure the INIT switch is placed in the “Normal” position.

Starting the Module Operation
After rebooting the TM-Series module, search for the module to make sure the settings have been changed. You can double click on the name of the module in the list to open
