2.2 DESCRIPTION
Measuring only 5.3 x 2 x 1.2 inches,
the Patton Model 1200
is the small-
est self-powered synchronous modem eliminator on the market. All
power is derived from the RS-232 data signals, so no AC power or bat-
teries are required. Constructed with a DB-25 connector on each end,
the Model 1200 can extend synchronous cable runs to 300 feet on each
side of the device. Optimum distance is achieved at 9600 bps, and strap
selectable data rates may extend up to 38,400 bps.
The Model 1200 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, 6.6mS or 53mS. The
carrier can be configured either as “constantly on” or “controlled by RTS”.
The Model 1201 has all the features of the Model 1200, plus LED indica-
tors that monitor receive data, request to send and data carrier detect on
each side of the device.
