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.
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:
| 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 follow the exact same pattern as A port.
The C-port outputs to Master board the following signals
| pin # | corresponding signal |
|---|---|
| C(31)-C(16) | unused, carrying logic-0 |
| C(15) | buffer is Full |
| C(14)-C(10) | unused, carrying logic-0 |
| C(9) | accumulation pre-trigger in this slave |
| C(8)-C(5) | hit information of bottom 4 channels |
| C(4)-C(1) | hit information of top 4 channels |
| C(0) | event pre-trigger in this slave |
The F-port is set to receives NIM based input signals(originated from TS)
| pin # | corresponding signal |
|---|---|
| F(7)-F(3) | unused |
| F(2) | Event mode trigger |
| F(1) | Accumulation mode trigger |
| F(0) | Helicity |
The G-port set for receiving NIM input signals (originated from Master v1495)
| pin # | corresponding signal |
|---|---|
| G(1) | MPS |
| G(0) | Global Clock |
