Input and Output naming convention
The CORIOmax protocol uses a fixed naming convention to communicate internally with
the various modules.
This naming is defined by the position of modules within the CORIOmax product. The
figure below shows the unit as viewed from the rear. Each location a module can be
placed is called a slot and each slot is numbered from the top left going across then down.
The first slot is numbered 1 the last is 20. Slot 17 is a special slot holding the CPU card
and slots 18,19 and 20 only work on data, not video signals.
The fixed label for slot1 is:
Slots.slot1
The Video Modules have inputs and outputs. Some cards have only one type others have
both and most have more than 1.
Inputs are addressed by
in1, in2
, etc and outputs are addressed by
out1,out2
, etc.
Like the slot numbering they are numbered from left to right looking from the rear.
The fixed label for the left-hand most input on slot 1 is
Slots.slot1.in1
The fixed label for the left-hand most output on Slot13 is
Slots.slot13.out1
The input numbering starts from 1 and continues to the number of inputs on the module.
