ICM40030

The ICM40030 is a Serial Converter Module provides the capability of interfacing equipment with RS-485 serial communications to equipment with RS-232 communications. Data format of the RS-232 and RS-485 equipment must be the same. For full-duplex (RS422), the DIP switch on the side of the module must be in the RS422 position. For half-duplex (RS485), the DIP switch must be in the RS485 position. In half-duplex mode, the RS485 driver is enabled using the leading edge of the first character transmitted (RXD input). After the last character transmits, the converter waits one character time (at 9600baud) to disable the RS485 driver. There are 3 LED's that can be viewed from the front of the converter module. A green power LED indicates power is ON, a red RS232 TXD LED flashes when the module is transmitting and a green RS232 RXD LED flashes when the module is receiving. An external DC power source (9 to 32VDC) is required to power the ICM4.
