Serial Ports 1 And 2 - Motorola MVME2603-1121A Installation And Use Manual

Serial Ports 1 and 2

On MVME761-compatible models of the MVME2603/2604 base
board, the asynchronous serial ports (Serial Ports 1 and 2) are
configured permanently as data circuit-terminating equipment
(DCE). The port configuration is illustrated in
Configuration of Serial Ports 3 and 4
The synchronous serial ports, Serial Port 3 and Serial Port 4, are
configurable through a combination of serial interface module
(SIM) selection and jumper settings. The following table lists the
SIM connectors and jumper headers corresponding to each of the
synchronous serial ports.
Port 3 is routed to board connector J7. Port 4 is available at board
connector J8. Eight serial interface modules are available:
You can configure Serial Ports 3 and 4 for any of the above serial
protocols by installing the appropriate serial interface module and
setting the corresponding jumper. SIMs can be ordered separately
as required.
