2.2 DESCRIPTION

The Patton Model 1203 high speed synchronous modem
eliminator allows two synchronous RS-232 DTE (host) devices to

communicate with each other without the need for expensive
synchronous modems. Supporting selectable data rates of 7, 14, 28,
56, 112 and 224 Kbps, the Model 1203 needs no AC power or batteries
for operation. The Model 1203 provides internal or external clock
options and operates half or full duplex. To emulate dial-up or
dedicated service, the delay between RTS and CTS can be set to either
0mS or 6.6mS. The carrier can be configured either as “constantly on”
or “controlled by RTS”.

Measuring only 5.3” x 2.0” x 1.2”, the Model 1203 is equipped with
a DB-25 connector on each end. Cable runs up to 75 feet on either
side of the device (150 feet total) are possible at the optimum data rate
of 64 Kbps. Tri-state LED indicators that monitor receive data, request
to send and data carrier detect on each side of the device.
