MODEL ICM4 - SERIAL CONVERTER MODULE (RS232C/RS485)
DESCRIPTION
The ICM4 Serial Converter Module provides the capability of interfacing
equipment with RS485 serial communications to equipment with RS232
communications. Data format of the RS232 and RS485 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 9600 baud) 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 32 VDC) is required to power the ICM4.
The external power source and serial communications connections are made via
a 12 position removable terminal block located on the front of the module.
The unit is equipped with a universal mounting foot for attachment to
standard DIN style mounting rails, including top hat profile rail according to
EN50022 - 35 x 7.5 and 35 x 15, and G profile rail according to EN50035 - G32.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Read complete instructions prior to
installation and operation of the unit.
