Programmable Output Status “LED” - Shows the current state of a programmable output. If the programmable output

function is set to “Channel Activity”, the LED will light any time any of the associated input channel(s) are active. If the

programmable output function is set to “Programmable Input State”, LED activity should be interpreted using the

information below:

Function State when LED On State when LED Off

Analog In Control Attenuation < 15dB Attenuation > 15dB

Increase In 1dB: Contact closure on prog input No contact closure on prog input

Decrease In 1dB: Contact closure on prog input No contact closure on prog input

Analog Out Control Attenuation < 15dB Attenuation > 15dB

Increase Out 1dB: Contact closure on prog input No contact closure on prog input

Decrease Out 1dB: Contact closure on prog input No contact closure on prog input

Memory Preset: Associated memory is active Associated memory is not active

Toggle Crosspoint Gain: Input-to-output(s) connection made Input - output(s) connection not made

Mute In: Associated input(s) not muted Associated input(s) muted

Mute Out: Associated output(s) not muted Associated output(s) muted

Apply Button - Applies the current setting of “Function” and “Applies To” to the current programmable output. When the

Apply button is enabled, this indicates that the setting of “Function” and “Applies To” in the AS16x12 does not match the

setting of “Function” and “Applies To” shown on the control panel screen. Clicking the Apply button will load the control

panel setting into the active AS16x12 setup.

This does not store the changes to a memory preset! That must be done

explicitly from the File/Save Active to AS16x12 Preset... file menu option. If changes are made to a programmable output

but not applied (by clicking on the Apply button), and another programmable output is selected (by clicking on of the Select

Programmable Output buttons), all the changes to the first programmable output which were not applied will be lost.

PROGRAMMABLE OUTPUT

FUNCTIONS:

Channel Activity - Allows the selected

programmable output to indicate activity

on one or more input channels. Anytime

least one of the inputs associated with a

particular programmable output is active,

the programmable output will be active.

This is useful for initiating activities which

must react to activity on specific channels.

One example is video-follow-audio, where

d i ff e rent cameras (or camera positions)

must be activated based on channel

activity. Note that on the Misc Settings tab, the input qualification time and output hold time may be set to optimize the

time response of channel activity for various applications. The screen below shows programmable output 1 responding to

activity on any of input channels 1, 2, or 3.

Programmable Input State - Allows the selected programmable output to indicate the current state of one of the

programmable inputs. This is particularly useful when you need to supply user feedback for the state of a bistate

programmable input. The programmable output may then be connected to a LED to show the state of the associated

programmable input.

When the room combining capability of the AS16x12 is used, a logic output will automatically be associated with each

Toggle Room Boundary programmable input. This will provide user feedback as to the combine status of each boundary

between two rooms. You’ll notice that the frame caption changes to include the phrase “(used for room combining)” as a

reminder that this programmable output cannot be changed in this tab.

A programmable output whose function is Programmable Input State will be active (i.e. conducting to ground) or inactive

(i.e. open) as follows depending on the function of the programmable input with which it is associated:
