MODULE OPERATION
Setting the
Module Address
Both the Racal Instruments Option-01T and 1256 switch controllers
identify each Adapt-a-Switch plug-in by a
module address
that is
unique to that module.
For setting the module address of the 1260-132 refer to one of the
following manuals.
•
1260-100 Adapt-a-Switch Manual – Publication No. 980824-100
(“Module Address Switch” section in Chapter 2)
•
1256 User Manual – Publication No. 980855 (“Numbering of
Plug-In Slots” section in Chapter 2)
1256 Operation
For a detailed description of the use of the 1260-132 when it is
being used in a 1256 Switch Controller, refer to the 1256 User
Manual (P/N 980855).
VXI Operating
Modes
The 1260-132 may be operated either in
message-based
mode or
in
register-based
mode when used with an Adapt-a-switch Carrier
in a VXI chassis.
In the
message-based
mode, the 1260-01T switch controller
interprets commands sent by the slot 0 controller, and determines
the appropriate data to send to the control registers of the 1260-132
module.
A conceptual view of the message-based mode of operation is
shown in
Figure 3-1
below.
