Four different Rear Connector Modules (RM) may be used with DACA214.
Each RM is a single slot high, so that up to 12 such modules, in any mix could
be fitted onto an FR2AV frame. Other Crystal Vision RM and Interface PCBs
can be mixed in any quantity with DACA214 PCBs, up to a maximum of 12
PCBs, providing the other PCBs do not exceed the power rating of the PSU
chosen (normally 150 watts).
The different RM connectors provide for both balanced and unbalanced audio
connectors. The available rear connectors are as follows:
Rear connectors

RM03
•
12 modules per 2U frame
•
For 110 Ohm balanced AES inputs
•
GPI lines also available at frame
remote connectors
•
All frame slots can be used
RM12
•
12 modules per 2U frame
•
For 75 Ohm unbalanced AES inputs
•
GPI lines also available at frame

•
All frame slots can be used
RM11
•
12 modules per 2U frame
•
For 110 Ohm balanced AES inputs
and if high density 26 way output
connector preferred
•
Ref In connector not used
•
GPI lines also available at frame
remote connectors
•
All frame slots can be used
RM35
•
12 modules per 2U frame
•
All frame slots can be used
Notes:
The RM11 is similar to the RM03, but has an additional BNC input for the reference
signals required for DACA214 PCBs, and has a high density 26 way D connector
instead of the standard 25 way D connector. If the rack frame has a mixture of
DACA214 and DACA214 PCBs, the user may wish to standardise on one common
RM11 for both DACA214 and DACA214 board types.
The RM03 can accept 75 Ohm circuits if required.
