DESCRIPTION
The ICM5 Serial Converter Module provides the capability of interfacing
equipment with RS485 serial communications to equipment with RS232
communications while providing three way isolation. Data format of the RS232
and RS485 equipment must be the same.
The unit can be configured for full duplex (RS422), or half duplex (RS485)
operation. In half duplex mode, the RS485 driver is automatically enabled using
the leading edge of the first character that is received on the RS232 side. After
the last character is received, the converter waits one character time (at the
selected baud rate) to disable the RS485 driver.
An external DC power source (+9 to 26 VDC) is required to power the ICM5.
The external power source and RS485 communications connections are made
via a 7-position removable terminal block located on the front of the module. A
modular RS485 connector is also provided for fast and efficient connection to
other Red Lion devices that use a modular connector. The RS232 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 RS232 TXD LED flashes when
the module is transmitting, and a green RS232 RXD LED flashes when the
module is receiving.
