Audio Console

The GPIO Console allows you to configure and view the 
state of the GPIO connectors found in the Codec C90 
and Codec C60.

To access this setup, click 

 on the menu bar.

The GPIO socket is designed for 6-pin Phoenix plugs 
with +12 V, GND and 4 ports for On/Off control.

Initially, a GPIO port is high (2–12 V

dc

) until a certain 

condition occurs, on which it will go low (0–1 V

dc

). 

Observe that maximum output current from the +12 V 
is 500 mA @ 12 V

dc

, while a port is capable of sinking 

500 mA  @  48 V

dc

. This means that in most cases the 

use of an external power supply to run external devices 
will be preferable, compared to driving an external unit 
from the codec’s +12V

dc

 power.

The following options exist:

 can be Output or Input

Output Direction: 
•

 can be used to force the output 

 

to go high or low. Since the codec will operate on its 
own, without the TC Console program controlling it, 
Manual State will not apply unless you use API to set 
up conditions.

•

. The port will go low when the system is in a 

call. 

•

. The port will go low when the 

microphones are muted.

•

. The port will go low when 

presentation (second video stream) is active.

•

. The port will go low when the all 

calls are encrypted.

•

. The port will go low when the system 

is active (not in standby).

Input Direction
•

. When the port goes low, the 

microphones will be muted.
