Time Code Outputs:
Each of the two time code outputs will drive a balanced
600 ohm line, providing a nominal level of +11 dBm.
Each output also may be used as 2 unbalanced outputs,
in which case they should be terminated with a 300 ohm
resistor to ground. It is not necessary to terminate
unused output pins. The required mating connectors
are Switchcraft A3F or equivalent. Pin 1 is ground and
the signal is on pins 2 and 3.
