MODEL ICM5 – THREE WAY ISOLATED SERIAL CONVERTER MODULE
(RS-232C/RS-485)
 9 PIN D-SUB CONNECTOR FOR RS-232 CONNECTION
 SWITCHABLE TERMINATION AND BIASING RESISTORS
 MODULAR RJ JACK OR SCREW TERMINAL FOR RS-485
CONNECTION

DESCRIPTION

The ICM5 Serial Converter Module provides the capability of interfacing
equipment with RS-485 serial communications to equipment with RS-232
communications while providing three way isolation. Data format of the
RS-232 and RS-485 equipment must be the same.
The unit can be configured for full duplex (RS-422), or half duplex (RS-485)
operation. In half duplex mode, the RS-485 driver is automatically enabled
using the leading edge of the first character that is received on the RS-232 side.
After the last character is received, the converter waits one character time (at the
selected baud rate) to disable the RS-485 driver.
An external DC power source (+9 to 26 VDC) is required to power the ICM5.
The external power source and RS-485 communications connections are made
via a 7-position removable terminal block located on the front of the module. A
modular RS-485 connector is also provided for fast and efficient connection to
other Red Lion devices that use a modular connector. The RS-232 connection is
provided via a standard D-SUB 9-pin male connector. The ICM5 can be
configured for DTE or DCE operation, allowing the use of modem or null-
modem cables.
There are 3 LEDs that can be viewed from the front of the converter module.
A green power LED indicates power is on, a red RS-232 TXD LED flashes
when the module is transmitting, and a green RS-232 RXD LED flashes when
the module is receiving.
