The Search-and-Test Program

One of the programs written by the Data Acquisition Software Group is called ``Search-and-Test.'' The purpose of the program is to test the most important modules in the CAMAC system. The program checks:

• the executive crate controller
• every branch coupler
• every crate controller

The program checks these modules by sending CAMAC commands to various sections of each module. Each one of these modules, after receiving a CAMAC command, returns a logical value called X. X = 1 means the module accepts the command. X = 0 means otherwise. Each module should accept a certain set of instructions (combinations of A and F). If a module rejects an instruction which it is suposed to accept, then there is probably something wrong with the module.

The program checks every function of each module by sending the appropriate A and F values, and checking the X returned.
