RS-232↔RS-422 INTERFACE CONVERTER

1.The Converter does not require special handshaking signals in order to operate.

2.The Converter should always be configured the opposite of the equipment it’s connected to if straight-through cabling is used. For example, if you are connecting a modem (a DCE device) to the Converter, configure the Converter’s port connected to the modem as DTE.

3.Some industrial controllers include RTS+, RTS-, CTS+, and CTS-. If necessary, in most cases, these can be jumpered together.

4.According to EIA specifications, RS-422 signals are A and B, where mark = B>A in voltage and space + A>B in voltage. Many manufacturers label their leads as + and -. In most cases, +=B and -=A is the scheme the Converter uses. However, some manufacturers have reversed this scheme. Consult the manufacturer of your RS-422 equipment if you have problems.

There are three models of the RS-232↔RS-422 Interface Converter.

•IC456A-R3 — a standalone unit for 115-VAC operation.

•IC456AE-R3 — a standalone unit for 230-VAC operation.

•IC456C-R3 — a printed circuit card for rack-mounted units.

The same RS-232↔RS-422 printed circuit card is used for both 115- and 230-VAC applications. An Interface Converter Rack (RM060) is available through your sales representative. This is a 19-inch rack capable of holding up to eight printed-circuit cards. The rack has its own power supply which is switch selectable between 115- and 230-VAC operation.

If you ordered the IC456A-R4 or IC456C-R4, you should have received cables with your RS-232↔RS-422 Interface Converter.
