Appendix
17.1. AES Audio and GPIO Pinout
The figure below describes the AES and GPIO pinout for the 6 RJ-45 connectors on the media block.
AES audio and GPIO Pinout
17.2 GPIO Power Details
GPIO Input Details
-------------------
Vin High min level is 3.5 Volts
Vin Low max level is 1.5 Volts
Iin min -20 uA
Iin max +20 uA
(Essentially no current flows; this is a voltage sensing device)
The GPI inputs have a 5.62K Ohm resistor pull-up to an isolated 5 Volts. Shorting the pins would send an input
high (“dry contact”)
GPIO Output Details
--------------------
Outputs use a solid state relay
Max voltage across relay contacts GPO_nA and GPO_nB = 200 Volts
Relay ON-resistance: Min = 6 / Typ = 10 / Max = 15 ohms
Relay Current limit: Min = 300 / Typ = 360 / Max = 460 mA
Relay output power dissipation (continuous) = 600 mW
