1 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. the unit is equipped with a universal mounting foot for attachment to standard din style mounting rails, including top hat profile rail according to en 50 022 - 35x7.5 and 35x15, and g profile rail according to en 50 035 - 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. specifications 1. power : +9 to 26 vdc @ 125 ma maximum. 85 ma typical power supply must be class 2 or selv rated. 2. rs-232 voltages : receive data pin : 30 vdc max. mark condition : 0.8 vdc space condition : 2.4 vdc transmit data pin : mark condition : -8 vdc (typ.) space condition : + 8 vdc (typ.) 3. rs-485 voltages : differential output voltage : 5 vdc max. under no load differential input voltage : 5 vdc max. mark condition : -0.2 vdc space condition : + 0.2 vdc rs-485 drive capability : up to 32 rs-485 receivers connected in parallel rs-485 drive disable time : one character time (at the set baud rate) 4. maximum cable length : rs-232 : 50 feet (15.24 m) rs-485 : 4000 feet (1219.2 m) 5. baud rate : 9600 min., 115200 max. 6. isolation : 1000 vdc 7. environmental conditions : operating temperature range : 0 to 50 c. storage temperature : -40 to + 75 c operating and storage humidity : 85% max. relative humidity (non-condensing) from 0 to 50 c model icm5 C three way isolated serial converter module (rs-232c/rs-485) (85.1) 3.35 (89) 3.5 .39 (10) (25) .98 comm comm pwr txd rs485 m2869 x made in u.s.a . red lion controls 57600 bau d 115200 bau d 38400 bau d off 4 wire/ on 2 wire off 422/ on 485 120 terminatio n off 4 wire/ on 2 wire off dce/ on dt e off dte/ on dce off dte/ on dc e off dce/ on dt e off 422/ on 485 york, pa . model icm5 must be set in groups switches * * * * * @ 125ma max. 9-26vdc class 2 19200 bau d 9600 baud pull up pull down rs232 10 6 2 1 3 5 4 7 9 8 nc 1 3 4 5 2 6 7 sply pwr on + vdc 422 485/ leds on rxa rxb txb txa 2 1 4 3 5 6 7 dimensions in inches (mm) caution: read complete instructions prior to installation and operation of the unit. ? 9 pin d-sub connector for rs-232 connection ? switchable termination and biasing resistors ? modular rj jack or screw terminal for rs-485 connection ? allows communications between rs-232 control equipment and products with rs-422/rs-485 serial communications ? three way isolation protects serial equipment from ground loops (1000 vdc) ? automatic rs-485 driver control ? dip switch selectable baud rates 9600, 19200, 38400, 57600, 115200 ? wide dc input power range (+9 to 26 vdc) ? half duplex (rs-485) and full duplex (rs-422) ? led indication for rxd, txd, and power ? universal mounting foot for din rail installation ? selectable dte & dce operation works with any rs-232 cable bulletin no. icm5-e drawing no. lp0529 released 09/14 tel +1 (717) 767-6511 fax +1 (717) 764-0839 www.redlion.net ul recognized component, file # e179259
