OVERVIEW
The PCM-ESCC is a PC/104 dual channel, multiprotocol data communications controller based upon the Z85230 Enhanced SCC. Each serial channel is independent and capable of synchronous or asynchronous data communications with either RS-232 or optional RS-422/ 485 electrical levels. The module can be configured to satisfy a wide variety of serial communications applications and can be used to interface to a terminal, printer, modem, or other serial system peripherals.
