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 VMEsystem 1000 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
vendors 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

These MVME712 family VMEmodules were tested in an FCC-compliant
chassis, and meet the requirements for Class A equipment. FCC compliance
was achieved under the following conditions:

1. Shielded cables on all external I/O ports.

2. Cable shields connected to earth ground via metal shell connectors
bonded to a conductive module front panel.

3. Conductive chassis rails connected to earth ground. This provides the path
for connecting shields to earth ground.

4. Front panel screws properly tightened.

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 Information

General Description

The MVME712 family modules are I/O transition modules for the MVME1xx
VMEmodule families. The LCP2 adapter assembly routes the I/O signals and
grounds from the P2 connector on the backplane at the MVME1xx
VMEmodule to the MVME712 family module. The MVME712 family module
routes the signals to the appropriate industry-standard connectors on its front
panel. The MVME712-13 and MVME712AM both have a built-in modem.

The MVME712x has four DB-9 connectors for the serial ports, one 25-pin
connector for the printer port, and a Telco modular jack on the front panel. The
serial ports are configured for use as
null modem cables.

General Description

The UDS 2242980 modem installed on the MVME712-13 or MVME712AM
module provides full duplex operation over the 2-wire Public Switch
Telephone Network (PSTN). The unit operates asynchronously at data rates of
0 to 300, 600, 1200, or 2400 bps, and synchronously at data rates of 1200 and
2400 bps. The modem uses both LSI and surface mount technologies to fit an
auto dial 224 modem on just 9.6 square inches of board space.

The modem provides transmit and receive filtering, adaptive equalization,
and modulation and demodulation. Dual Tone Multi-Frequency (DTMF) tone
encoding is also provided. Circuitry is included to aid you in telephone call
progress monitoring for busy tone, reorder, and dial tone detection, and a
buffered audio output is also provided.

The modem provides command selection of either pulse or DTMF auto
dialing. Also included is automatic answer and automatic speed adjustment to
the speed of the originating modem. For applications requiring unattended
operation, these features make the 2242980 card an ideal solution. The auto
dialing command set is compatible with the popular ÒATÓ command set.

MODEM

A

The modem also includes integral diagnostic test features which aid in
isolating communication faults to the phone line, the modem, or the data
terminal equipment. Tests that may be performed include Analog Loopback,
Analog Loopback Self Test, Digital Loopback, Remote Digital Loopback, and
Remote Digital Loopback Self Test.
