Notes on wiring
CRL Code
- The CRL code downloaded to the VME crate contains important information. For example:
- Determining which channels are used
- The trigger channel on the TI
- The data input channel used on the c-ram 550
- The number of channels sent from the gassiplex must be matched in the CRL code as well to create the proper clock signal
- Determining which channels are used
Sources and Destinations
GEM gassiplex boards
The GEM gassiplex boards require the following inputs:
- Clock signal from Sequencer
- Track and Hold Signal from delay generator
- Clear Signal from Delay Generator
The GEM gassiplex boards send the following output
- Multiplexed data
Delay Generator
The delay generator expects the following as inputs:
- Trigger signal from scintillators or other source
The delay generator has the following outputs:
- Track and Hold signal for gassiplex boards
- Clear signal for gassiplex boards
- Electronics trigger to VME crate
VME crate
The VME crate expects the following as input:
- Electronics trigger signal from delay generator
- Multiplexed data from gassiplex boards
The VME crate have the following output:
- Clock Signal for gassiplex boards
