The
RS-232´RS-422 Interface Converter
provides bidirectional
synchronous or asynchronous conversion of all commonly used
RS-232 and RS-422 signals. It is designed to operate with one port
configured as Data Terminal Equipment (DTE) and the other port as
Data Communications Equipment (DCE).
RS-232 and RS-422 signals. It is designed to operate with one port
configured as Data Terminal Equipment (DTE) and the other port as
Data Communications Equipment (DCE).
The converter has two user-selectable configurations: one for
connecting RS-422 modem equipment to RS-232 terminal equipment
(DCE to DTE) and one for connecting RS-232 modem equipment to
RS-422 terminal equipment (DCE to DTE). Both configurations allow
bidirectional data transfer.
(DCE to DTE) and one for connecting RS-232 modem equipment to
RS-422 terminal equipment (DCE to DTE). Both configurations allow
bidirectional data transfer.
Three models are available:
• A standalone unit for 115-VAC operation (IC456A-R5).
• A standalone unit for 230-VAC operation (IC456AE-R3).
• A printed circuit card for rackmounted units (IC456C-R5).
• A standalone unit for 230-VAC operation (IC456AE-R3).
• A printed circuit card for rackmounted units (IC456C-R5).
The same RS-232´RS-422 printed circuit card is used for both
115- and 230-VAC applications, since the card itself derives power
from the rack unit in which it is installed.
OVERVIEW
The converter is easy to set for DCE or DTE operation. Simply
install the DIP shunts in the correct sockets on the circuit board.
One configuration is for connecting RS-422 DCE to RS-232
DTE. The other configuration is for connecting RS-232 DCE to
RS-422 DTE.
RS-422 DTE.
There is also a receiver termination switch on the circuit board.
It has a termination switch to insert 120-ohm resistance between
the receive data input leads. To enable termination, set the switch
to the ON position. To disable termination, set the switch to the
OFF position.

You might want to order the Interface Converter Rack (RM060),
which is a 19-inch rack that can hold up to eight printed circuit cards.
The rack has its own power supply that is switch-selectable between
115 and 230 VAC. (For 48 VDC, use RM062A).

The converter has seven LEDs located on the front panel that
indicate the status of the input signals.
There are LEDs for DSR (Data Set Ready), CTS (Clear To Send),
and Data to show the conditions on the RS-232 interface, and a
duplicate set of LEDs to show the conditions on the RS-422 interface.
There’s also an LED to indicate PWR (power).

TYPICAL APPLICATION
Connect an industrial controller’s RS-422 interface to your
computer’s RS-232 interface.
