T
he RS-232↔RS-422 Interface
Converter provides bidirec-
tional synchronous or async-
hronous conversion of all
commonly used RS-232 and
RS-422 signals. It is designed to
operate ith one port configured
as Data Terminal Equipment
(DTE) and the other port as Data
Communications Equipment
(DCE).
The converter has t o 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 allo bidirectional
data transfer.
Three models are available:
• A standalone unit for
115-VAC operation (IC456A-
R5).

Connect RS-422 modem
equipment to RS-232 terminal
equipment (DCE to DTE) or
RS-232 modem equipment to
RS-422 terminal equipment
(DCE to DTE) for bidirectional
data transfer.
KeyFeatures
RS-232↔RS-422INTERFACECONVERTER
• 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 applica-
tions, since the card itself derives
po er from the rack unit in hich
it is installed.
You might ant to order the
Interface Converter Rack
(RM060), hich is a 19-inch rack
that can hold up to eight printed
circuit cards. The rack has its
o n po er supply that is s itch-
selectable bet een 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 sho the conditions
on the RS-232 interface, and a
duplicate set of LEDs to sho the
conditions on the RS-422
interface. There’s also an LED to
indicate PWR (po er).

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.
There is also a receiver termination s itch on the circuit board. It
has a termination s itch to insert 120-ohm resistance bet een the
receive data input leads. To enable termination, set the s itch to the ON
position. To disable termination, set the s itch to the OFF position.
