Chapter Five:
Configuring GPIO
This chapter explains how to set up QOR GPIO. We
also invite you to read the GPIO Node User’s Manual ,
for more in-depth information on the topic of GPIO.
GPIO Port Definitions
The QOR.16 has four DA-15 connectors and the
QOR.32 has 8 DA-15 on the back panel. Each connec-
tor (also known as a GPIO port) can be associated with
a device in your studio, and provides five opto-isolated
inputs and five opto-isolated outputs per device for ma-
chine control, lamp drives and remote channel controls.
GPIO ports can also be monitored and controlled by our
PathfinderPC software.
GPIO ports are programmed to support several dif-
ferent types of devices. How does a GPIO port “know”
which type of device is assigned to it?
Back in Chapter 2, when you constructed a Source
Profile for a telephone hybrid, you defined the source
type (see “Adding Backfeeds and GPIO to a Source Pro-
file”). This is important, because when that source is as-
signed to a console fader, this Source Profile selection
defines the GPIO port what sort of command to send to
the attached device.
If the Source Profile is a microphone, it tells the
GPIO Node to send logic for
On, Off, Remote Mute
and Remote
Talk
commands on the appropriate pins. A
line input, the GPIO port sends
Start, Stop
and
Reset
commands, plus closures for
Ready
lights, etc.
Axia GPIO ports can deliver unique command sets
for the following types of devices:
1. Mic (Operator, Guest, Producer)
2. Line Input
3. Codec
4. Telephone Hybrid
5. Computer Playback Device
6. Control Room Monitor
The next few pages contain tables that explain what
function the pins provide in each different device mode.
