Case Let’s assume that C2 is off-air for a start (i.e., GPOutputFunction 16 of C2
is low). The
F5
user key on C2 is dark. The
F5
user key on C1 is illuminated,
indicating that a call signal from C1 to C2 is allowed.
• The C1 operator presses his
F5
key; GPOutputFunction 11 and input 1 of
AND2 go high. The output of AND2 goes high, too
• The output of AND3 alternates with the rate of GPOutputFunction 1
(generator), and the GPInputFunction 5 of C2 makes the C2
F5
key
(UserLED5) flash.
• The output of AND1 alternates too and makes the F5 key on C1 (UserLED5)
flash via XOR1.
• Operator C2 confirms the call signal by pressing his flashing F5 key. Input
2 of AND4 goes high. Since input 1 of AND4 (output of AND2) is high as
well, the output of AND4 goes high and turns, via the GPInputFunction
17, the GPOutputFunction 11 off again.

Case If C2 is on-air (i.e., GPOutputFunction 16 of C2 is high), the C1
F5
key is
dark.
• The C1 operator presses his F5 key; GPOutputFunction 11 and input 1 of
AND2 go high.
• Since input 2 of AND2 is low (output of NOT1 is low), the ouptut of AND3
remains low and the
F5
key on C2 remains dark; the C2 operator is not
disturbed.
• The output of AND1 still alternates and makes the F5 key on C1 flash,
telling the C1 operator that his call has been sent out.
• As soon as C2 goes off-air, the output of NOT1 changes from low to high,
opening the call signal path to C2; the F5 key on C2 flashes.
• Operator C2 confirms the call signal by pressing his flashing
F5
key. Input
2 of AND4 goes high. Since input 1 of AND4 (output of AND2) is high as
well, the output of AND4 goes high and turns, via the GPInputFunction
17, the GPOutputFunction 11 off again.
Notes As can easily be seen from the diagram above, the whole logic is implemented
in console C1. This is not mandatory, but allows implementing custom logic
in a system that also incorporates OnAir 2500 consoles without a memory
upgrade.
Configuration Procedure Although the logic diagram is not very complicated, a structured procedure
is recommended. Implementing the desired functionality is much easier if a
diagram is available where also the gate inputs are numbered.
First of all, since no hardware GPIOs are used, neither GPInputs nor GPOut-
puts need to be configured in our case – all that needs to be done takes place
in the GPIOFunctions and CustomLogic sections of the configuration tool.
