ASYNC 232↔422/530 CARD

2. Introduction

The Async 232↔422/530 Card is a dual rack card incorporating two
converters. The converters let computers, terminals, and modems using the
RS-232 interface communicate with devices using RS-422 balanced electrical
signals. Both units operate full duplex at data rates to 19.2 Kbps over 2 twisted
pairs. The Async 232↔422/530 Card features 13 easy-to-read front-panel
LEDs, which monitor the status of data transmission. As an added feature,
a set of easily accessible configuration straps allows the user to control the
function of the carrier-detect LEDs.
The Async 232↔422/530 Card uses the latest surface-mount technology
for high-quality short-range modem performance in a convenient rack card.
Filling one function card slot on the MicroRack (RM202, RM204, RM208, and
RM216) chassis, the Async 232↔422/530 Card is available with RJ-11 or RJ-45
rear interface cards.
