- SERIAL COMMUNICATIONS
- 4 x asynchronous serial channels provided by the
equivalent of 4 x 16550 UARTs
- implemented by:-
- 2 x
National Semiconductor® Super I/O devices
- all serial I/O via 68-way front panel connector
(break-out cable available to 4 x 25w D-Type connectors)
and via rear
I/O connector (J14)
- asynchronous data rates up to 1.5Mbps full duplex
- RS422 or RS485 mode is supported and the mode is software
detectable
- operates in RS422 mode supporting:-
- RS422
supports Tx, Rx, CTS, RTS, DCD, DSR, DTR and RI
- operates in RS485 mode supporting:-
- Tx and Rx only (Tx and Rx lines for each channel may be
connected together)
- jumperable resistor termination
- master/slave jumpers that are accessible via software
- flow control is provided by DTR signal of each channel
