- ROC28: SIS3801 scaler "C"; ARS modules 0x4, 0x5, 0x6, 0x7, 0x8
- ROC29: SIS3801 scaler "D"; ARS modules 0x9, 0xA, 0xB, 0xC, 0xD
- DVCS trigger crate
- NIM crate
- ROC30: SIS3801 scaler "E"; DVCS trigger readout card

## Channel layout for SIS3801 scalers "A" and "B" and CAEN V1290 TDC

The input signals for SIS3801 scalers "A" and "B" and CAEN V1290 TDC are daisy chained from "A", to "B", then terminate at the TDC. Scalers "A" and "B" have had their internal termination resistors removed. Both scalers are gated by the spectrometer scaler gate, but scaler "B" is further disabled by the DVCS trigger busy (which includes the TS busy). Both scalers and the TDC are latched by a narrow pulse formed from the ARS_valid signal.
