The CBDULMTrigger is intended to control a LeCroy 2367 ULM situated on a camac branch rooted in a VME crate by a CES CBD8210 branch driver. If you intend to utilize the driver in a camac crate controlled by a CCUSB, see the ULMTrigger command. It provides the exact same functionality but understands the CCUSB to be its controller.
The CBDULMTrigger cannot be registered as a stack module by itself. Instead it must be registered first to a CBDCamacCrate. That CBDCamacCrate must then be registered to a CBDCamacBranch module.
Two options need to be specified to function properly. The first is firmware which defines the location of the firmware file to load. The second is the slot number in the camac crate it lives in.
On initialization the module will always be cleared and the GO bit set to 1.
At the end of the run, the GO bit is set to 0.
During stack execution initiated by an event trigger, the following logic is carried out:
if "-registerRead" is true
Read the register
if "-eventwiseClear" is true
Clear the register
By default, both -registerRead and -eventwiseClear are set to false.
Specifies the slot of the CAMAC crate the target module is occupying. Default is 1.
The path to the firmware file usbtrig.bit. Default is "".
Specifies whether to add a hit register read into the event stack. Defaults to true.
Specifies whether to send a clear command via the CAMAC dataway at the end of the event. Defaults to true.
By default, the ULM will only load the firmware if it fails to validate the configuration. This occurs always after a bad firmware load or after a crate has been power cycled. Firmware loads take a bit of time so it is worthwhile to skip reloading the firmware on every run. However, sometimes it may be considered useful. This option causes the firmware to be loaded at the start of EVERY run. Defaults to false.
Specifies the number that will be used to validate a successful firmware configuration. This number is compared to the value returned by the function A=15 F=0.
