A port

This is used as an input. The signals from patch1(slave-1) will be ported to A-port of the master board.

pin # corresponding signal
A(0) independent event trigger in strips 1-32
A(1) OR of strips 1-4 on plane 1
A(2) OR of strips 1-4 on plane 2
A(3) OR of strips 1-4 on plane 3
A(4) OR of strips 1-4 on plane 4
A(5) OR of strips 28-32 on plane 1
A(6) OR of strips 28-32 on plane 2
A(7) OR of strips 28-32 on plane 3
A(8) OR of strips 28-32 on plane 4
A(9) independent accumulation trigger in strips 1-32
A(15) buffer of slave-1 busy(half-full)


B port

This is an input port. The signals from patch2(slave-2) will be ported to B-port of the master board.

pin # corresponding signal
B(0) independent event trigger in strips 33-64
B(1) OR of strips 33-36 on plane 1
B(2) OR of strips 33-36 on plane 2
B(3) OR of strips 33-36 on plane 3
B(4) OR of strips 33-36 on plane 4
B(5) OR of strips 61-64 on plane 1
B(6) OR of strips 61-64 on plane 2
B(7) OR of strips 61-64 on plane 3
B(8) OR of strips 61-64 on plane 4
B(9) independent accumulation trigger in strips 33-64
B(15) buffer of slave-2 busy(half-full)


C port

The C-port is a fixed output port and is currently unused.


D port

This is an input port. The signals from patch3(slave-3) will be ported to D-port of the master board.

pin # corresponding signal
D(0) independent event trigger in strips 65-96
D(1) OR of strips 65-68 on plane 1
D(2) OR of strips 65-68 on plane 2
D(3) OR of strips 65-68 on plane 3
D(4) OR of strips 65-68 on plane 4
D(5) OR of strips 93-96 on plane 1
D(6) OR of strips 93-96 on plane 2
D(7) OR of strips 93-96 on plane 3
D(8) OR of strips 93-96 on plane 4
D(9) independent accumulation trigger in strips 65-96
D(15) buffer of slave-3 busy(half-full)

Rest all pins in A, B & D ports are floating


E port

The E-port is an input port for following NIM based signals:

pin # corresponding signal
E(0) Helicity reversal signal (called MPS)


F-port

The F-port is used as an output port for following NIM based signals:

pin # corresponding signal
F(7) slave-1 buffer busy
F(6) slave-2 buffer busy
F(5) slave-3 buffer busy
F(4) event pre-Trigger raw
F(3) accumulation pre-Trigger raw
F(2) global clock
F(1) global clock
F(0) global clock

G-port

The G-port is used as an output port for following NIM based signals:

pin # corresponding signal
G(0) final Accumulation Trigger
G(1) final Event Trigger
