Serial Ports 1-4 DCE/DTE Configuration
Serial ports 1 through 4 are configurable as modems (DCE) for
connection to terminals, or as terminals (DTE) for connection to
modems. The MVME712M is shipped with the serial ports
configured for DTE operation. Serial port DCE/DTE configuration
is accomplished by positioning jumpers on one of two headers per
port. The following table lists the serial ports with their
corresponding jumper headers.

The next six figures illustrate the MVME2603/2604 base board and
MVME712M transition module with the interconnections and
jumper settings for DCE/DTE configuration on each serial port.
Serial Port 4 Clock Configuration
Port 4 can be configured via J15
RtxC4 signal lines. Part of the configuration is done with headers
J16, J17, and J20 on the MVME2603/2604 (Figures 1-9 and 1-10).
