System Requirements
The following requirements must be fulfilled to build a functional system:
Exactly one MCP module, one MDC module and one MDO module are required for a system (up
to 8 racks) (non-redundant design). The MDC module must be properly connected by ribbon cable
to the MDO module mounted in the front panel.
NOTICE
In the standard design with a MAT module installed in the rack, the first MAI module must be
inserted into slot 7 (Pos. 2), the 2nd MAI module into slot 9 (Pos. 4), etc. Thus the measurement
channel numbers obtained are: 1st MAI module (Pos. 2): 9–16. 2nd MAI module (Pos. 4): 25–32,
etc.
It is extremely important to ensure that the modules plugged into the rear are compatible
with the modules inserted in the front (e.g., the combination of an MAI module with an
MRO8 module is non-functional [see table below])
.
The modules plugged into the rear must be located at the same slots as the modules with the
associated functions plugged into the front.
Slots in the Rack
Slots 1–3: slots for MCP and/or MDC modules only
Slots 4–5: slots for MDA modules only (deprecated)
Slots 6–13: slots for INPUT/OUTPUT modules
Slots 14–15: slots for INPUT/OUTPUT (but no MAI) modules only
INPUT:
MAI/MAR modules
MBC modules
MGI/MGR modules
OUTPUT: MGO module
MAO module
MBC module
MST: connection site for the MST module only
(Positions 1–10): connection site for:
- MAT module
(8 x 5 terminals)
- MUT module (40-way ribbon cable)
- MRO8 module (Position 9!)
