❏ An SCSI interface (via P2 adapter) for connection to both internal
and external devices
❏ Socket-mounted SCSI terminating resistors for end-of-cable or
middle-of-cable configurations
❏ Provision for modem connection
❏ Green LED for SCSI terminator power; yellow LED for Ethernet
transceiver power
The features of the P2 adapter board include:
❏ A 50-pin connector for SCSI cabling to the MVME712M and/or to
other SCSI devices❏ Socket-mounted SCSI terminating resistors for end-of-cable or
middle-of-cable configurations
❏ Fused SCSI terminator power developed from the +5VDC present
at connector P2
❏ A 64-pin DIN connector to interface the EIA-232-D, parallel, SCSI,
and Ethernet signals to the MVME712MSerial 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 (Figure 1-4)to use the TrxC4 and RtxC4
signal lines. Part of the configuration is done with headers J16, J17, and
J20 on the MVME2603/2604 (Figure 1-9 and Figure 1-10).P2 Adapter Preparation
Preparation of the P2 adapter for the MVME712M consists of removing or
installing the SCSI terminating resistors. Figure 1-11 illustrates the
location of the resistors, fuse, and connectors.
For further information on the preparation of the transition module and the
P2 adapter, refer to the user’s manual for the MVME712M (listed in
Appendix D, Related Documentation) as necessary
