Slave-1:
The A, B, D and E ports take LVDS, 32 bit input signal information from the top 32 strips of planes 1, 2, 3 and 4 respectively.
Strips on detector and Pins on the input port are counted from 1 onwards (instead of 0).
Pin 1 is indicated by a white arrow on the port of v1495. The pattern in which signals are given into the pins are as follows:
A port
The A port is an input and receives LVDS from QWAD boards in the tunnel via the 200' cable.
| pin #: DD strip # | pin #: DD strip # |
|---|---|
| A(32): strip 32 | A(16): strip 31 |
| A(31): strip 30 | A(15): strip 29 |
| A(30): strip 28 | A(14): strip 27 |
| A(29): strip 26 | A(13): strip 25 |
| A(28): strip 24 | A(12): strip 23 |
| A(27): strip 22 | A(11): strip 21 |
| A(26): strip 20 | A(10): strip 19 |
| A(25): strip 18 | A(9): strip 17 |
| A(24): strip 16 | A(8): strip 15 |
| A(23): strip 14 | A(7): strip 13 |
| A(22): strip 12 | A(6): strip 11 |
| A(21): strip 10 | A(5): strip 9 |
| A(20): strip 8 | A(4): strip 7 |
| A(19): strip 6 | A(3): strip 5 |
| A(18): strip 4 | A(2): strip 3 |
| A(17): strip 2 | A(1): strip 1 |
The B, D and E ports follow the exact same pattern as A port.
C-port
The C-port is used as an output on slave-1 and has the following signals.
| pin # | corresponding signal |
|---|---|
| C(32): st21,p4 & st19,p3 | C(31): st20,p4 & st18,p3 |
| C(30): st19,p4 & st17,p3 | C(29): st18,p4 & st16,p3 |
| C(28): st17,p4 & st15,p3 | C(27): st16,p4 & st14,p3 |
| C(26): st15,p4 & st13,p3 | C(25): st14,p4 & st12,p3 |
| C(24): st13,p4 & st11,p3 | C(23): st12,p4 & st10,p3 |
| C(22): st11,p4 & st9,p3 | C(21): st10,p4 & st8,p3 |
| C(20): st9,p4 & st7,p3 | C(19): st8,p4 & st6,p3 |
| C(18): st7,p4 & st5,p3 | C(17): st6,p4 & st4,p3 |
| C(16): Pattern buffer busy | C(15): pipeline delay of strip-5,plane 2 |
| C(14): pipeline delay of strip-4,plane 2 | C(13): pipeline delay of strip-3,plane 2 |
| C(12): pipeline delay of strip-2,plane 2 | C(11): pipeline delay of strip-1,plane 2 |
| C(10): independent event pre-trigger in this slave | C(9): OR of bottom 2 strips(# 28-32) in this part of plane-4 |
| C(8): OR of bottom 2 strips(# 28-32) in this part of plane-3 | C(7): OR of bottom 2 strips(# 28-32) in this part of plane-2 |
| C(6): OR of bottom 2 strips(# 28-32) in this part of plane-1 | C(5): OR of top 2 strips(# 1-4) in this part of plane-4 |
| C(4): OR of top 2 strips(# 1-4) in this part of plane-3 | C(3): OR of top 2 strips(# 1-4) in this part of plane-2 |
| C(2): OR of top 2 strips(# 1-2) in this part of plane-1 | C(1): accumulation pre-trigger in this slave |
F-port
The F-port is set to receives NIM based input signals(originated from TS)
| pin # | corresponding signal |
|---|---|
| F(8) | sync signal(to be used for diagnosis) |
| F(7)-F(4) | unused |
| F(3) | event-trig input |
| F(2) | accum-trig input |
| F(1) | Helicity (H+) |
G-port
The G-port set for receiving NIM based input signals
| pin # | corresponding signal |
|---|---|
| G(2) | MPS L1A (the Level-1-Accept for MPS generated by TS) |
| G(1) | Global Clock (originated from Master v1495) |
All other slaves also follow the same pattern for all their input/output ports.
