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 null­modem 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.

DIMENSIONS In inches (mm)

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.

switches etc.) typical anti-static precautions should be observed before
touching the unit.

EMC INSTALLATION GUIDELINES

Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of
electrical noise, source or coupling method into the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.

1. DC power to the unit should be relatively clean and within the specified

limits. Connecting power to the unit from circuits that power inductive loads

that cycle on and off, such as contactors, relays, motors, etc., should be

avoided. This will reduce the chance of noise spikes entering the DC power

2. The shield (screen) pigtail connection should be made as short as possible.

connection and affecting the unit.

The connection point for the shield depends somewhat upon the application.

Listed below are the recommended methods of connecting the shield, in

order of their effectiveness.

a. Connect the shield only at the unit to earth ground (protective earth).

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is above 1 MHz.

c. Connect the shield to common of the unit and leave the other end of the

shield unconnected and insulated from earth ground.

3. Never run Signal cables in the same conduit or raceway with AC power lines,
conductors feeding motors, solenoids, SCR controls, and heaters, etc. The
cables should be run in metal conduit that is properly grounded. This is
especially useful in applications where cable runs are long and portable two­way radios are used in close proximity or if the installation is near a
commercial radio transmitter.

4. Signal cables within an enclosure should be routed as far away as possible
from contactors, control relays, transformers, and other noisy components.

5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
cables as close to the unit as possible. Loop the cable through the core several
times or use multiple cores on each cable for additional protection.
Install line filters on the power input cable to the unit to suppress power line

interference. Install them near the power entry point of the enclosure. The
following EMI suppression devices (or equivalent) are recommended:

Ferrite Suppression Cores for signal cables:

Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0

Line Filters for input power cables:

Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3

Note: Reference manufacturer’s instructions when installing a line filter.

6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.

baud switches should be in the ON position.

Switches 6-7 - PULL UP / PULL DOWN

These switches connect 4.7 K biasing resistors to the A and B lines of the
485 receiver. To minimize loading of the network, these should only be used if
no other device in the system provides biasing.

Switches 8-9 - OFF 4 WIRE / ON 2 WIRE

These switches can be used to internally jumper the A and B lines of the
RS-485 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.

Switch 10 - 120  TERMINATION

This switch connects a 120  resistor across the A and B lines of the RS-485
receiver. The use of the resistor prevents signal reflection, or echoing, at high
baud rates, over long distances. This should only be turned on if the ICM5 is
the first, or last, device in a multi-drop network that is experiencing reflection
due to long cable distances.

Bottom Bank of 7 Switches

Switches 1-2 - OFF 422 / ON 485

These switches enable and disable the automatic RS-485 driver control. In
the 422 position, the driver is always enabled, allowing 4-wire full duplex
operation. In the 485 position, the driver is enabled as soon as characters are
received on the RS-232 side. When the RS-485 driver has transmitted the last
character, it waits one character time (at the selected baud rate), and then enters
a high-impedance state. The receiver is also enabled and disabled in a similar
fashion to prevent transmitted characters from being echoed back. This allows
2-wire, half-duplex operation, without the use of handshake lines. Both
switches should be in the same position.

Switch 3 - N/C

No Connection

Switches 4-7 - OFF DCE / ON DTE

These switches configure the RS-232 port to act as a DCE or DTE device.
With all of the switches in the DCE position, pin 2 of the DB-9 connector is the
RS-232 receiver, and pin 3 is the RS-232 transmitter. DTE configures pin 2 as
the transmitter, and pin 3 as the receiver. These switches allow the use of
modem or null-modem cables. All of these switches should be in the DCE or
DTE position. No other combinations are valid.

standard DIN style mounting rails, including G profile rail according to
EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5
and 35 x 15. The unit should be installed in a location that does not exceed the
maximum operating temperature and provides good air circulation. Placing the
unit near devices that generate excessive heat should be avoided.

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. To remove a module from the
rail, push up on the bottom of the module while pulling out away from the rail.

T Rail Installation

To install the ICM5 on a "T" style rail, angle the module so that the top
groove of the "foot" is located over the lip of the top rail. Push the module
toward the rail until it snaps into place. To remove a module from the rail,
insert a screwdriver into the slot on the bottom of the "foot", and pry upwards
on the module until it releases from the rail.
