II.4.2 LINE level input (International Sound Input – Int. in)
This is an additional line level input which can be mixed with the headphone
outputs to provide the international sound to the commentators.
II.4.3 Second auxiliary line level output.
Called REC output, this output can carry the program line signal, the return from
the program line or the sum of both signals. This is a balanced XLR connector.
II.4.4 Auxiliary data: GPIO and RS232 ports.
The GPIO port on a DB9 connector allows remote control/signalling by means of
remote contact closures. There are two ground contact inputs and two relay
outputs.
A RJ45 connector at the rear panel provides a serial port (RS232 port) for
sending/receiving auxiliary data along with the encoded audio for IP and ISDN
communications.
