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) 1.

The following EMI suppression devices (or equivalent) are recommended: Fair-Rite part number 0443167251 (RLC part number FCOR0000) Line Filters for input power cables: Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000) 6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life. b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. RLC part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000 7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation. Although Red Lion Controls Products are 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 the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment. 1. A unit should be mounted in a metal enclosure, which is properly connected to protective earth. 2. Use shielded cables for all Signal and Control inputs. The shield connection should be made as short as possible. 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 to earth ground (protective earth) at one end where the unit is mounted. b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1 MHz. 3. Never run Signal or Control 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 through metal conduit that is properly grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components. 4. Long cable runs are more susceptible to EMI pickup than short cable runs. 5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is Visit RLC’s web site at http://www.redlion.net/Support/InstallationConsiderations. html for more information on EMI guidelines, Safety and CE issues as they relate to Red Lion Controls products. 2 SIDE VIEW OF ICM5 LEDS DTE Top Bank of 10 Switches Switches 1-5 - BAUD Select the appropriate baud rate.

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.
