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.
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.

General Information
1-4 MVME712-10 Transition Module and I/O Distribution Set UserÕs Manual

For minimum RF emissions, it is essential that the conditions above be
implemented; failure to do so could compromise the FCC compliance of the
equipment containing the modules.
General Description
The MVME712-10 Transition Module is a low-cost I/O transition board for
MotorolaÕs MVME166 Single Board Computer VMEmodules and their
peripheral devices. Refer to Figure 1-1.
The MVME712-10 routes the signals to the appropriate industry standard
connectors on its front panel. This board can be mounted either next to the
MVME166 or in the back of the chassis. The board contains four shielded 8-pin
RJ45 jacks for EIA-232-D serial interface, a shielded DB-15 connector for
Ethernet, and a shielded DB-25 connector for parallel interface.
The MVME712-10 also provides conversion from the 68-pin high-density SCSI
connector to a standard 50-pin low-density SCSI connector.
Each EIA-232-D serial port transmits the following signals:
❏
Data carrier detect
❏ Request to send
❏ Transmit data
❏ Receive data

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:
Ð Mode 0, submode 1X
Ð Bits 7 to 4 as inputs
Ð Bits 3 to 0 as outputs.
❏ Port B direction must be:
Ð Mode 0, submode 1X
Ð Bit 7 as an output
Ð Bits 6 to 0 as inputs
Write port B bits 7 to 0 set configuration mode. Now port A bits 3 to 0 are used
to select a port.
