6.2 The VP-1201 Input Buttons
The Input buttons on the front panel give the following indications:
 The blue LED illuminates when a valid input is connected
 The red LED illuminates when an input is routed to the output but no
valid signal is detected on the input
 Both the blue and red LEDs illuminate (creating purple) when a valid
input signal is being routed to the output
To understand how the Input button LEDs function, consider the following
example:
Figure 28 shows an acceptor connected to the VP-1201 unit and 3 sources
connected to inputs # 1, 5 and 10.
On the front panel we can see that:
 The blue LEDs in buttons 1, 5 and 10 are illuminated (indicating that
these 3 sources are connected and active)
 The red LED in button 2 is illuminated (indicating that Input 2 is routed to
the output – but there is no active source connected to Input 2)
= Red
= Purple
= Blue

We now want to route Input 5 to the output (see Figure 29). To do so we have
to press the Input 5 button. On the front panel we can see that:
 The blue LEDS are illuminated in Input buttons 1, and 10
 The red and blue LEDs in button 5 are also illuminated (creating purple)
because input 5 is now routed to the output
 The Input 2 button no longer illuminates
