Function
The upstream equipment forces this
signal low when it is ready to send a
panel to the 5DX.
The 5DX forces this signal low when
it is ready to accept the panel from the
upstream equipment.
The 5DX forces this signal low when
it is ready to send a panel to the
downstream equipment.
The downstream equipment forces
this signal low when it is ready to
accept the panel from the 5DX.
The 5DX uses this signal to indicate
that the panel being sent has been
tested and is good.
The 5DX uses this signal to indicate
that the panel being sent has not been
tested.
The 5DX with the middle rail
installed uses this signal to indicate
that the panel being sent in the rear
lane has been tested and is good.
