Cooling Requirements
Motorola VMEmodules are specified, designed, and tested to operate reliably
with an incoming air temperature range from 0 degrees C to 55 degrees C (32
degrees F to 131 degrees F) with forced air cooling.
Temperature qualification is performed in a standard Motorola MVME900
series chassis. Twenty-five watt load boards are inserted in the two card slots,
one on each side, adjacent to the board under test to simulate a high power
density system configuration. An assembly of three axial fans, rated at 71 CFM
per fan, is placed directly under the MVME card cage. The incoming air
temperature is measured between the fan assembly and the card cage where
the incoming airstream first encounters the module under test.
Test software is executed as the module is subjected to ambient temperature
variations. Case temperatures of critical, high power density integrated
circuits are monitored to ensure component vendor specifications are not
exceeded.
While the exact amount of airflow required for cooling depends on the
ambient air temperature and the type, number, and location of boards and
other heat sources, adequate cooling can usually be achieved with 5 CFM
flowing over the module. Less air flow is required to cool the module in
environments having lower maximum ambients.
Specifications
1
Under more favorable thermal conditions it may be possible to operate the
module reliably at higher than 55 degrees C with increased air flow. It is
important to note that there are several factors, in addition to the rated CFM of
the air mover, which determine the actual volume of air flowing over a
module.
FCC Compliance
The MVME712-10 transition board was tested in an FCC-compliant chassis,
and meets the requirements for Class A equipment. FCC compliance was
achieved under the following conditions:
❏
Shielded cables on all external I/O ports.
❏
Cable shields connected to earth ground via metal shell connectors
bonded to a conductive module front panel.
❏
Conductive chassis rails connected to earth ground. This provides the
path for connecting shields to earth ground.
❏
Front panel screws properly tightened.

MVME712-10 Module Preparation
Serial Port Configuration
The four RJ45 EIA-232-D serial ports are factory configured as terminal (DTE)
for connection to modem. However, they can be used as modem-to-terminal
(DCE) by using an appropriate user-supplied external DCE adapter.
Serial Port DCE Configuration
Figure 2-2 shows the schematic representation of the DCE configuration of
serial ports 1 through 4, using a user-supplied external DCE adapter.
Serial Port DTE Configuration
Figure 2-3 shows the schematic representation of the DTE configuration of
serial ports 1 through 4, using a user-supplied external DTE adapter.
Configuration Register
Figure 2-4 illustrates the function of the configuration register on the
MVME712-10. The application software on the MVME166 can read the
configuration information to identify the transition board(s) in the system.
On the MVME166, the MC68230 interrupt level is the same as the CD2401. The
interrupt vector is as programmed in the MC68230. The interrupt priority is (1)
first the CD2401, and (2) then the MC68230.
To read the configuration information, the MC68230 (PI/T) must be
programmed as follows:
Port A direction must be:
❏
ÐMode 0, submode 1X
ÐBits 7 to 4 as inputs
ÐBits 3 to 0 as outputs.
❏
Port B direction must be:
ÐMode 0, submode 1X
ÐBit 7 as an output
ÐBits 6 to 0 as inputs
2
Write port B bits 7 to 0 set configuration mode. Now port A bits 3 to 0 are used
to select a port.

Installation Instructions
Rear Chassis Mount, Internal SCSI Devices
To mount the MVME712-10 at the rear of the chassis with internal SCSI
devices, proceed as follows and see Figure 2-7.
1.Insert the MVME712-10 module into the selected slot at the rear of the
chassis and tighten the attaching screws.
2.Connect the furnished P cable from connector J6 on the MVME712-10 to
connector J8 on the front of the MVME166. A longer cable may be needed
for some chassis conÞgurations.
3.If the P cable at J6 on the MVME712-10 covers connector J5, connect a usersupplied cable with compatible pinouts from connector J7 on the
MVME712-10 to the internal SCSI device. If connector J7 is covered,
connect the cable to J5.
Caution
Caution
J5 and J7 are functionally the same. Do NOT use both at the
same time, because to do so would create a SCSI stub greater
than .1 meter.
SCSI terminators must be installed on the devices that are
physically located at each end of the SCSI cable, and must
not be on other devices on the cable. Refer to the SCSI
specification for detailed instructions.

4.Connect the furnished 100-conductor I/O cable between connector J9 on
the MVME712-10 and I/O connector J9 on the MVME166. A longer cable
may be needed for some chassis conÞgurations.
5.Install the cover that you previously removed, making sure that it does not
pinch any cables.
6.Connect the power cable to the AC power source and turn the unit on.

Introduction
This chapter provides the interconnection signals, parts lists with parts
location illustrations, and schematic diagrams for the MVME712-10 Transition
Module.
Manual T erminology
An asterisk (*) following the signal name for signals which are level significant
denotes that the signal is true or valid when the signal is low.
An asterisk (*) following the signal name for signals which are edge significant
denotes that actions initiated by that signal occur on high to low transition.
Interconnect Signals
80-pin connectors J1 through J4 on the MVME712-10 correspond to the RJ45
EIA-232-D serial ports on the MVME712-10 front panel.
J5 and J7 are identical 50-pin connectors for low-density 8-bit-wide SCSI cable
(one is accessible from the front and one from the back of the board) and are
connected internally to J6, a high-density 16-bit-wide SCSI connector for the P
cable. Connector J6 is cabled to connector J8 on the MVME166.
3
Caution
J8 is a 25-pin connector for the printer port, and J10 is a 15-pin connector for
the Ethernet interface.
J9 is a 100-pin connector that is cabled to connector J9 on the MVME166 SBC
for I/O.
All front panel connectors have metal shells and jack posts that are electrically
connected to the front panel. If the front panel is electrically connected to the
chassis ground then the shells and jack posts are connected to chassis ground.
This allows shielded cable to be used for effective reduction of EMI and RFI
problems.
