2.2 DESCRIPTION
The Model 2021 RS-232 to X.21 converter lets a synchronous
RS-232 device communicate bi-directionally with a synchronous X.21
device. The Model 2021 requires no AC power or batteries to operate
and supports data rates to 384 Kbps. Operating full or half duplex, the
Model 2021 passes all necessary clocking and control signals, and is
transparent to protocol.
The Patton Model 2021 connects directly to the synchronous
RS-232 interface using a male or female DB-25 connector. A male or
female DB-15 connector at the end of an integral 6 foot cable plugs into
the X.21 interface. In most cases, this eliminates the need for special
crossover cables. Housed in an ultra-minature case measuring only
3.56"L x 2.10"W x 0.80" H, the Model 2021 fits easily into tight
locations. The Model 2021 is manufactured by Patton Electronics in
the USA.
