Serial Port Interface Modules
You may configure the asynchronous/synchronous serial ports (ports 3 and
4) to the appropriate interface by installing a Serial Interface Module
(SIM). A SIM is a small “plug-in” printed circuit board that converts the
TTL-level synchronous or asynchronous port signals to industry standard
voltage levels used by the ports. The SIM contains the receiver and
transmitter circuits for converting the input and output signals of the host
VMEmodule to the appropriate serial data communication protocol.
The SIMs for the MVME761-0x1 are listed in the following table.
Note
Additional SIMs may be released. Please see your Motorola
representative for a complete list of SIMS that are available
for the MVME761-0x1.
