Integration of the Atrium processor within an X-Bus cable segment

General

As standard, the Atrium processor is equipped for fitting at the start of the X-Bus, and so the line termination A/ is built into it.

If you wish to integrate the processor within an X Bus cable segment, two optional TSX PCI ACC1 accessories make it possible to do so:

a shield fitted with:
- SUB-D 9 pin connector to connect a TSX CBY• X-Bus cable,
- a cable for connecting the SUB-D 9 pin connector to the processor card,
a daughterboard fitted with two connectors that act as an interface between the processor card and the SUB-D 9-pin connector of the shield described above. This daughterboard is fitted instead of and in place of the line termination A/, fitted as standard on the processor card.

Note: The optional TSX PSI 2010 24 V power supply also enables you to perform this function.

Installation procedure

Carry out the following steps:

Step	Action	Illustration
1	Remove the line termination A/ located on the processor.
2	Install the daughterboard instead of the line termination A/.
3	As the processor card is in position in the PC, fix the shield in the available slot, located immediately on the right of the processor card as indicated on the figure above.
4	Connect the cable to the connector of the daughterboard installed in step 2.

NOTE: In this case, since the processor is no longer integrated at the start of the line terminations TSX TLY EX A/ and /B must be installed on each of the racks located at the end of the line.
