Functional Description

MVME162IG/D2 1-17

❏ One of the following output connectors on the MVME712X transition

module:

MVME712M: The DB-25 connector marked SERIAL PORT 4 on the front

panel. SERIAL PORT 4 can be configured as an EIA-232-D DTE or DCE

port, via the jumper headers J18 and J19 on the MVME712M.

MVME712A, AM, -12, or -13: The DB-9 connector marked SERIAL PORT

4 on the front panel. SERIAL PORT 4 is hard-wired as an EIA-232-D DTE

port.

Figure 2-3 (sheets 1 through 6) in Chapter 2 illustrates the six configurations

available for Port B when the MVME162 is used with an MVME712M. Note

that the port configurations shown in Figure 2-3 sheets 5 and 6 are not

recommended for synchronous applications because of the incorrect clock

direction. Figure 2-4 (sheets 1 and 2) shows an MVME162 with the two

configurations available with EIA-530 SIMs. Figure 2-5 (sheets 1 through 4)

shows the four configurations available for Port B when the MVME162 is used

with an MVME712A/AM/-12/-13.

Caution

Do not simultaneously connect serial data devices to the

equivalent ports on the MVME712 series transition module

and the MVME162 front panel. This could result in simul-

taneous transmission of conflicting data.

Caution

Do not connect peripheral devices to Port 1, Port 3, or the

Centronics printer port on the MVME712X module.

Caution

When using an EIA-530 SIM, do not connect the MVME162

to an MVME712X board. The EIA-530 signals are not

supported by the P2 adapter and the transition boards.

IndustryPack (IP) Interfaces

The IPIC ASIC on the MVME162 supports four IndustryPack (IP) interfaces:

these are accessible from the front panel. Refer to the IPIC Programming

Model in the MVME162 Embedded Controller Programmer’s Reference Guide for

details of the IP interface. Refer to the MVME162 Embedded Controller Support

Information manual for the pin assignments of the IP connectors.

Optional LAN Ethernet Interface

The MVME162 uses the 82596CA to implement the Ethernet transceiver

interface. The 82596CA accesses local RAM using DMA operations to perform

its normal functions. Because the 82596CA has small internal buffers and the
