J228 PCSER4
Introduction
The PCSER4 is an 8-bit ISA bus add-on board providing 4 channels of RS232/485 Serial
Comms. It is based on the 85230 Enhanced Serial Communications Controller and is capable of
RS232, RS422 or RS485 signalling standards. Every channel can be independently configured
for and synchronous protocols, baud rate and signalling standard. High speed asynchronous
communications can be achieved up to 115kBaud (asynchronous) or 1.8Mbaud (synchronously).
All serial channel connections are routed through the 50-way metal-shelled ‘D’-type connector.
