Bottom Tray

The bottom tray(s) hold the input boards, which contain the signal conditioning components
for the analogue and digital input channels and the status relay outputs. It is connected to the
acquisition board by two ribbon cables. The large central one is for the analogue and digital
data signals, the smaller left hand one is for the status outputs and for programming the
FPGAs on the input boards.
Note: The top-most input board must be maintained in this position. This
board contains the Status Output circuitry, and cannot be moved to any
other position in the enclosure.
At the
right rear of each input board is a strip of spring metal fingers. These slide against a bracket
on the rear panel to make a connection for the protective earth ground. It is important to
ensure that these contacts are kept clean. The signal input connectors are mounted directly
on the rear of the input board with no interposing cables or boards. The actual configuration
of voltage and current inputs is detailed in the Project Summary supplied with the unit.

Front Panel

Inside the front panel is a board that carries the status LEDs and test button. It is connected
to the acquisition board via a 14-conductor IDC cable. Below this board is the serial port
connector (used with Display Station), which is linked to the processor board via a 9-
conductor cable.

Status LEDs

There are ten indicators on the front panel that display the system status. Four of these
functions are also available as relay outputs on the rear panel. The ten LEDs have the
following functions:
