ASYNC 232↔422/530 CARD
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.

CHAPTER 3: Configuration
This section describes the location and orientation of the Async
232↔422/530 Card’s configuration jumpers, provides detailed instructions
on setting each jumper, and describes the settings for each of the rear
connection cards.
The Async 232↔422/530 Card uses two jumpers that allow configuration to a
wide range of asynchronous applications. These jumpers are accessible when
the card is slid out of the rack chassis. Once the hardware is configured, the
Async 232↔422/530 Card is designed to operate transparently, without need
for frequent re-configuration: Just set it and forget it.

3.1 Jumper Locations and Orientation
The configuration jumpers on the Async 232↔422/530 Card and the
rear interface card allow you to configure the function of both front-panel
“Carrier Detect” LEDs, as well as the rear interface card CD signal. Figure 3-2
shows the orientation of these jumpers. Notice that each jumper can be either
on pegs 1 and 2, or on pegs 2 and 3. Note: Pin 1 is always located on the top
or left side of the jumper set.

CHAPTER 3: Configuration
3.2 Setting the Configuration Straps
The Async 232↔422/530 Card contains two sets of configuration jumpers,
which allow you to set the function of both front-panel “Carrier Detect” LEDs
and the CD signal exiting the rear interface card in the rack. Since the Async
232↔422/530 Card contains two converters, each unit can be configured
separately.
Both “Carrier Detect” straps can be set to “Normal” or “Always on.” When
operating normally, the “CD” LED will blink to indicate the presence or
absence of the carrier. When set to “Always on,” the CD LED will always
indicate that the carrier is ON. The table below summarizes the jumper
settings. The default position is “Always on.”
Interface Card Jumper Summary Table
Jumper Function Position 1 & 2 Position 2 & 3
JP1—Unit A Carrier Detect “Always ON” “Normal”
JP2—Unit B Carrier Detect “Always ON” “Normal”
3.3 Rear-Card Configuration
The Async 232↔422/530 Card has two interface-card options: the IC474C
(which comes equipped with two RJ-11 ports and two RJ-45 ports) and the
IC475C (which comes equipped with four RJ-45 ports). Figure 3-3 shows
these options.
