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
Clear to send
Data terminal ready
Cables Required
The following cables are needed in order to connect the MVME712-10 to the
MVME166 and other devices:
One 100-conductor, 25 mil pitch cable to connect the MVME712-10 to the
MVME166 for I/O (a 1-foot-long cable is furnished by Motorola).
One 68-conductor, 25 mil pitch P cable to connect the SCSI port on the
MVME712-10 to the SCSI port on the MVME166 (a 1-foot-long cable is
furnished by Motorola).
One 50-conductor, 50 mil pitch A cable for 8-bit wide SCSI connection to
internal SCSI devices (customer-supplied).
