Connecting a Module Assembly
The individual modules and interface submodules of a module assembly can be
connected via commercially available cables and connectors.
Requirements
The connector housings and cables must meet the following requirements:
Connector housing: The height and width of the connector housing must not
exceed 43 mm and 19 mm respectively. It must have a 45
°
side outlet for the
cable. These requirements are met by the connector housings of cables and
lines listed in the chapter on spare parts and accessories of the
reference
manual /1/.
Cables: Only cables which have a braided shield may be used. The shield must
have a low-resistance connection to the housing ground.
Components to be Connected
A module assembly can comprise the following components to be connected:
Application function module and interface submodules
EXM 478 expansion module with interface submodules
ATM 478 AT adapter module with short AT card
MSM 478 mass storage module with parallel interface
Connecting Interface Submodules
The interface submodules are equipped with subminiature D female or male
connectors. To connect devices to the interface submodules, you must fabricate
cables with the appropriate mating connectors or obtain preassembled,
commercially available cables.
The pin assignments of the subminiature D connectors can be found in the
description of the relevant interface submodule in the chapter on interface
submodules of the
reference manual /1/.
Connecting the Mass Storage Module
Pin assignments of the parallel interface of the MSM 478 mass storage module
can be found in the chapter on M7-400 expansion of the
reference manual /1/.
Connecting the Short AT Card
The interface pin assignments of short AT cards which you intend to use can be
found in the corresponding documentation.
