Remote Status and Control
The MVME2603/2604 front panel LEDs and switches are mounted on a
removable mezzanine board. Removing the LED mezzanine makes the
mezzanine connector (J1, a keyed double-row 14-pin connector) available
for service as a remote status and control connector. In this application, J1
can be connected to a user-supplied external cable to carry the Reset and
Abort signals and the LED lines to a control panel located apart from the
MVME2603/2604. Maximum cable length is 15 feet.
Table 4-1
in
Chapter 4, Connector Pin Assignments
lists the pin numbers
and signal mnemonics for J1.
MVME712M Transition Module Preparation
The MVME712M transition module (
Figure 1-3
) and P2 adapter board are
used in conjunction with the MVME2603/2604 base board.
The features of the MVME712M include:
❏
A parallel printer port
❏
An Ethernet interface supporting AUI connections
❏
One synchronous/asynchronous, and three asynchronous only,
EIA-232-D multiprotocol serial ports
❏
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
