Connecting the M-Module
2.1
Peripheral Interfaces
There are two possibilities for connecting peripherals:
• Connection via 25-pin D-Sub connector.
• Connection via the carrier board.
Pin assignment of the connectors depends on the type of input signal conditioning.
The different versions available of the M36N (8 channels differential, 16 channels
single-ended etc.) result in different standard pin assignments. A detailed
description—including the applicable assignment tables—can be found in
.
2.1.1
Connection via 25-pin D-Sub Connector
Connector types:
• 25-pin D-Sub receptacle according to DIN41652/MIL-C-24308, with thread bolt
UNC 4-40
• Mating connector:
25-pin D-Sub plug according to DIN41652/MIL-C-24308, available for ribbon
cable (insulation piercing connection), hand-soldering connection or crimp con-
nection
Note: For the M36N to pass the radio disturbance test according to EN55022
shielded cables have to be used.
2.1.2
Connection via Carrier Board/24-pin Connector
When a carrier board with a 96-pin DIN 41612 PCB connection is used for
peripheral signals (for example a 6U VMEbus board), these are fed to the M-
Module through the 24-pin receptacle connector. You can connect up to four 21-pin
connectors to the 96-pin connector (cf. carrier board manual). When these
connectors are used, for each M-Module three pins of the DIN 41612 PCB
connector cannot be used. The pin numbers for the 96-pin connector shown below
are valid for M-Module slot number 3. If other M-Module slots (2, 1 or 0) are used,
the value 8, 16 or 24 must be added as appropriate.
Connector types:
• Two 12-pin receptacles, high-precision, 2.54mm pitch, for square pins
