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.
Figures 1-5 through 1-10 illustrate the MVME2700 base board and
MVME712M transition module with the interconnections and jumper
settings for DCE/DTE configuration on each serial port.
