MVME761 Transition Module
The MVME761 transition module (Figure 1-12 on page 1-26) and P2
adapter board are used in conjunction with the MVME2603/2604 base
board.
The features of the MVME761 include:
❏ A parallel printer port (IEEE 1284-I compliant)
❏ An Ethernet interface supporting 10BaseT/100BaseTX connections
❏ Two EIA-232-D asynchronous serial ports (identified as COM1 and
COM2 on the front panel)
❏ Two synchronous serial ports (SERIAL 3 and SERIAL 4 on the front
panel), configurable for EIA-232-D, EIA-530, V.35, or X.21
protocols
❏ Two 60-pin Serial Interface Module (SIM) connectors
Serial Interface Modules
The synchronous serial ports on the MVME761 are configurable via serial
interface modules (SIMs), used in conjunction with the appropriate jumper
settings on the transition module and base board. The SIMs are small plugin printed circuit boards which contain all the circuitry needed to convert TTL-level port to the standard voltage levels needed by various industrystandard serial interfaces, such as EIA-232, EIA-530, etc. SIMs are
available for the following configurations:This chapter summarizes the pin assignments for the following groups of
interconnect signals for the MVME2603/2604:
❏ Connectors with pin assignments common to MVME712M, as well
as MVME761-compatible versions of the base board❏ Connectors with pin assignments specific to MVME761-
compatible versions of the base board
The following tables furnish pin assignments only. For detailed
descriptions of the various interconnect signals, consult the support
information documentation package for the MVME2603/2604 single
board computer or the support information sections of the transition
module documentation as necessary
