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

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.


C-port

The C-port output on slave-1 has the following signals.

pin # corresponding signal
C(32): pl_delay signal in strip 32 C(31): pl_delay signal in strip 31
C(30): pl_delay signal in strip 30 C(29): pl_delay signal in strip 29
C(28): pl_delay signal in strip 28 C(27): pl_delay signal in strip 27
C(26): pl_delay signal in strip 26 C(25): pl_delay signal in strip 25
C(24): pl_delay signal in strip 24 C(23): pl_delay signal in strip 23
C(22): pl_delay signal in strip 22 C(21): pl_delay signal in strip 21
C(20): pl_delay signal in strip 20 C(19): pl_delay signal in strip 19
C(18): pl_delay signal in strip 18 C(17): pl_delay signal in strip 17
C(16): buffer is Full C(15): pipeline delay of strip-5
C(14): pipeline delay of strip-4 C(13): pipeline delay of strip-3
C(12): pipeline delay of strip-2 C(11): pipeline delay of strip-1
C(10): independent event pre-trigger in this slave C(9): OR of bottom 4 strips(# 28-32) in this part of plane-4
C(8): OR of bottom 4 strips(# 28-32) in this part of plane-3 C(7): OR of bottom 4 strips(# 28-32) in this part of plane-2
C(6): OR of bottom 4 strips(# 28-32) in this part of plane-1 C(5): OR of top 4 strips(# 1-4) in this part of plane-4
C(4): OR of top 4 strips(# 1-4) in this part of plane-3 C(3): OR of top 4 strips(# 1-4) in this part of plane-2
C(2): OR of top 4 strips(# 1-4) 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)-F(4) unused
F(3) Event mode trigger
F(2) Accumulation mode trigger
F(1) Helicity (H+)

G-port

The G-port set for receiving NIM input signals (originated from Master v1495)

pin # corresponding signal
G(2) MPS
G(1) Global Clock

All other slaves also follow the same pattern for all their input/output ports.
