Trigger inputs¶
We will probably want to make this into a database table or at least a form in ECL.
2016.02.25¶
Add two new LARSCINT-based triggers.
18 BLIP | Optical trigger on small isolated flashes (currently not in use) 19 SCINTGATE | 400 microsecond gate following each LARSCINT for use as cosmic veto on pedestal triggers
2015.09.14¶
Add BUSY inputs to the V1495 in the new upper bits:
29 BUSYA | Logical OR of all 8 TPC V1740s' BUSY signals 30 BUSYB | Trigger and µRS V1740 BUSY 31 BUSYC | Two V1751s' BUSY logical OR
BUSYA intended for the VETO patterns
BUSYC intended for the <OFF> trigger pattern section.

- Ribbon cable, lines 0-15 from the C port to the V1751 digital in/out
- Fast and delayed triggers from LEMO G1 and G0 go to NIM logic fanouts, but currently stop over at a discriminator first, which lengthens them to 50ns. This is a precaution to make sure all boards can see them.
- Reset on channel 0 LEMO is from $00. Note, this is very confusing. For two reasons:
- The D and G ports can do input and output. When used as inputs they have inverted logic. That is, if you have a register bit hooked up to D2 and you assert a NIM signal on the input at -700mV the register will read 0, not 1.
- The mapping of the D ports to internal registers is not what you might expect:
