Installation

 

5  Installation 

Six different rear connector modules (RM) may be used with ADCA412. There are 

single, dual and triple slot versions available offering a variety of I/O options and rack 

population densities. Other Crystal Vision RM and Interface PCBs can be mixed in any 

quantity with the ADCA412, up to a maximum of 24 PCBs, providing the other PCBs do 

not exceed the power rating of the PSU chosen (normally 150 watts). 

The available rear connectors are as follows:

Notes: 

The RM11 is similar to the RM03, but has an additional BNC input for the reference 

signals required for ADCA412 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 ADCA412 PCBs, the user may wish to standardise on one common 

RM11 for both DACA214 and ADCA412 board types. 

The RM03 can accept 75 Ohm circuits if required. 

Only plug the ADCA412 cards into the top slot associated with the RM13 rear module, 

the bottom slot is not used and MUST be left vacant.
