2.2 DESCRIPTION
The Model 2015 RS-449/422 to V.35 converter lets a
synchronous RS-449/422 device communicate bi-directionally with a
synchronous V.35 device. The Model 2015 requires no AC power or
batteries to operate and supports data rates to 2 Mbps. Operating full
or half duplex, the Model 2015 passes all necessary clocking and
control signals, and is transparent to protocol.
The Patton Model 2015 connects directly to the synchronous
RS-449/422 interface using a male or female DB-37 connector. A male
or female M/34 connector at the end of an integral 6 foot cable plugs
into the V.35 device. Models with any combination of "DCE" and "DTE"
wiring are available, thus eliminating the need for special crossover
cables.
Housed in an ultra-miniature case measuring only 2.66" x 2.10" x
0.73", the Model 2015 fits easily into tight locations. Like all Patton
products, the Model 2015 is manufactured by Patton Electronics in the
USA.
