Racal Instruments Ó2003
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 1260-152 and 1260-172
refer to one of the following manuals.
· 1260-100 Adapt-a-Switch Manual – Publication No. 980824-100
· 1256 User Manual – Publication No. 980855
For a detailed description of the use of the 1260-152 and 1260-
172 when they are being used in a 1256 Switch Controller, refer to
the 1256 User Manual (P/N 980855).
The 1260-152/172 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-
152/172 module.
A conceptual view of the message-based mode of operation is
shown in Figure 3-1 below.
