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.

Summary of Contents for red lion ICM5

  • Page 1 RS485 driver. provided by the equipment may be impaired. 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 CAUTION: via a 7-position removable terminal block located on the front of the module.
  • Page 2 8. CERTIFICATIONS AND COMPLIANCES: 9.CONSTRUCTION: Case body is green, high impact plastic. Installation Category I, Pollution Degree 2. SAFETY 10. MOUNTING: Standard DIN rail top hat (T) profile rail according to IEC 1010-1, EN 61010-1: Safety requirements for electrical equipment EN50022- 35 X 7.5 and 35 X 15 for measurement, control, and laboratory use, Part 1.
  • Page 3 These switches can be used to internally jumper the A and B lines of the RS485 driver and receiver together. This allows 2-wire operation without the use of external jumper wires. To use the RJ-11 connector, the ICM5 must be in 2-wire mode. Both switches should be in the same position.
  • Page 4 G Rail Installation To install the ICM5 on a "G" style DIN rail, angle the module so that the upper groove of the "foot" catches under the lip of the top rail. Push the module toward the rail until it snaps into place.
