9.3.1 GPIO TTL/Relay selection
Each RJ45 connection on I/O cards handles audio signals and GPIOs.
The GPIO pins can be configured to work as:
•
TTL in and out
this is selected by GPIO1 jumpers in the place 12 and GPIO2 jumpers in place 45. These
jumpers are located on the I/O cards, close to the RJ45 connectors.
