Control Crate modules and boards¶
A number of MICE subsystems are controlled via VME-based computers in crates at the top of the relevant rack.
If a failure has been identified in one of these, you will need to
- power off the crate
- pull out the affected carrier board
- replace the relevant module
- re-insert carrier board
- restart crate
- The Target crate has a few foibles
The Carrier Boards are all 8002's but the ones with the CANbus interface need to have prom version V306. It is a 8 pin DIL device that can easily be swapped between boards.
You must check with a CAM expert before doing anything!
The attachments below list the modules within each crate:
- CS1: Decay Solenoid
- CS2: Target Vac-Rack
- CS3: Target R78
- CS4: Magnet PSU's
- CS8: "Tracker (temporary)" - though I think this is actually something to do with the R9 AFC test.
You should double-check that the module which you have been asked to change matches that listed.
The VME crates usually have a Terminal Server to provide access over the network; if not, the crates' serial connection parameters are: RS-232, 9600 baud, 8 bit, No parity, 1 Stop bit.
