9.3 Global Inputs/Outputs
9.3.1 GPIOs
The in-/outputs can be used for global functionality for example synchronization, remote function, relay
logic etc…
Each Sub-D connector represents 2 GPIO's.

GPO-A and GPO-B make connection if the GPO is activated!
Maximum current: 200 mA
Maximum resistance when connection made: 12 Ohm
Maximum Voltage: 24 V
9.3.2 Word clock in and out.
On the rear side of the Lyra you can find two BNC connectors with the text FCLK OUT and FCLK IN.
These are the word clock in/out connection which can be used for synchronization purposes.
If the Lyra is the last in the synchronization chain, you can use the TERM. switch to terminate the line. (75
Ohm Termination)
