RHIC Scaler Setup at STAR

The scaler connection to RHIC is in the RHIC rack in the DAQ room. As of 7 June 2000 we are sending the following channels to RHIC:

1. ZDCE sum over threshold
2. ZDCW sum over threshold
3. ZDCE.and.ZDCW
4. unk
5. unk
6. unk
7. unk
8. unk
9. low M bit
10. medium M bit
11. high M bit
12. unk
13. PIN 1
14. PIN 2
15. PIN 3
16. PIN 4

The connections to this scaler for the ZDC and M bits come to the back of the RHIC rack. These signals originate on the platform and are sent to the DAQ rom via a GLINK board.
