1.0 INT~OOUCTION.
The General Purpose Asynchronous Data Communications Module provides a
general purpose EIA RS232C or 20 mA dc current loop link from the ter-
minal to an external device. The GP Async Data Comm peA transmits and
receives bit serial data to and from the external oevice throuqh an
interface cable assembly, provides parallel-to-serial and serial-to-
parallel conversion, and transmits and receives bit oarallel data to
and from the terminal through the Backplane Assembly (data bus).
2.0 OPEPATING PARAMETERS.
A summary of operating parameters for the GP Async Data Comm Module is
contained in tables 1.U through 6.5.
