2.2 DESCRIPTION
The B&B Model 2011 asynchronous to synchronous converter plugs
directly into a local asynchronous DTE (terminal, PC, etc.) and connects
that DTE, via RS-232 cable, to a synchronous DCE. When the same set-up
is installed on the remote end, the local and remote DTEs can
communicate over the synchronous link.
Drawing power from either the synchronous or asynchronous
RS-232 interface, the Model 2011 needs no AC power or batteries to
operate and supports RS-232 data rates from 64 Kbps. Because the Model
2011 automatically adjusts the synchronous data rate to match the
asynchronous DTE's output rate, no data rate strapping is
necessary. The Model 2011 derives clocking externally from the clock of
the synchronous DCE, and imposes no limit on data block size. Characters
may be up to 11 bits long.
Measuring only 3.2" x 2.0" x .75", the Model 2011 is housed in a sturdy
ABS plastic case. It comes fully equipped with a DB-25 male connector and
a DB-25 female connector, which plug directly into the synchronous and
asynchronous ports.
