2.2  DESCRIPTION

The Model 1004ARC high speed, multipoint short range modem

rack card is a 

dual rack card incorporating two short range modems.

Both units support asynchronous data rates to 115.2 Kbps over 1 or 2
twisted pairs and support distances to 9.4 miles (19 AWG @19.2
kbps). The Model 1004ARC features 6 easy-to-read front panel LEDs
and incorporates Silicon Avalanche Diodes for protection against the
damaging effects of nearby lightning strikes and other harmful tran-
sients.

The Model 1004ARC can handle up to 50 terminal drops in a mul-

tipoint polling environment. For RS-485 and serial printer applications
requiring hardware handshaking, the Model 1004ARC passes one con-
trol signal in each direction. The Model 1004ARC may be configured
for high or low impedance operation, carrier may be set to “constantly
on” or “controlled by RTS”, and the unit can operate with or without
“echo”. RTS/CTS delay may be set for “no delay” or 8 mS.

Filling one function card slot on Patton’s Model 1000R16 rack

chassis, the Model 1004ARC is available with RJ-11 or RJ-45 rear
interface cards. For workgroup and desktop communications, the
Model 1004ARC also fits in Patton’s 2, 4 and 8 slot ClusterBoxes™.
The combination of rack mount, ClusterBox™ and self-powered units
provides a completely integrated Model 1004A “networking” solution.

NOTE:

Packages received without an RMA number will not be

accepted.
