1General Information
Introduction
This manual provides general information, hardware preparation,
installation instructions, and support information for the
MVME760 Transition Module.
The MVME760 module is used as the interface between host
VMEmodules and various peripheral devices. A 64-pin ribbon
cable (P/N 30-W2514B02, 17” length) connects the MVME760
Transition Module to the host VMEmodule.
Features of the MVME760 Module
The features of the MVME760 module include industry-standard
connectors that interface to:
❏ Two EIA-232 asynchronous serial ports
❏ Two synchronous serial ports
❏ One parallel port (IEEE Standard 1284-I compliant)
❏ Ethernet interface (both AUI and 10BaseT)
❏ Two 60-pin connectors are provided to support existing MCG
Serial Interface Modules. Currently, there are four types of
SIMs available: EIA-232 DCE, EIA-232 DTE, EIA-530 DCE,
and EIA-530 DTE. The selection of these modules determines
the functionality of the two synchronous serial ports.

Specifications
The MVME760 module specifications are shown in Table 1-1.
Cooling Requirements
The MVME760 module has minimal active circuitry. In general,
convection cooling will suffice. However, care must be taken such
that other system components or other external sources of heat do
not cause the actual operating temperature to exceed the specified
operating temperature.

FCC Compliance
The MVME760 module was tested in an FCC-compliant chassis,
and meets 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 Description
The MVME760 Transition Module provides the interface between
standard Ethernet, Parallel Port, and the Serial Port connectors and
the Host board P2 connector. The Ethernet and Parallel Ports
contain passive circuitry only. The I/O controllers themselves
reside in the host board. The Serial Ports contain active circuitry, to
provide multiplexing and buffering functions (reference Figure 3-1,
MVME760 Transition Module Block Diagram). The multiplexing
function is transparent to the user. Two 60-pin headers are
provided to support existing MCG Serial Interface Modules.
Currently, there are four types of Serial Interface modules available
as shown in Table 1-2:
