2.3.2Audio Connections

The digital audio inputs and reference input are provided on female BNC connectors. Input signals should be compliant with AES3-id-1995 (unbalanced, 75Ω , 1V peak-to- peak standard output). AES3-id signals are very similar to analog composite video, although dedicated AES3 distribution equipment should be used. If the loop-through BNC connectors are not being used to feed additional equipment, terminate them with a standard 75Ω video terminator.

The digital audio output is provided on a female BNC connector. The output is 75Ω, unbalanced, with signal levels compliant with AES3-id-1995.

The DP563 allows remote control via the front-panel (RS-232) or rear-panel (RS-

485) ports. It is able to communicate at rates of 9.6 kbps, 19.2 kbps, or 38.4 kbps. The unit address can be any discrete tributary address as specified in SMPTE RP 113- 1996. See Section 6.4 for further information. The default address is 8280, and the serial I/O connections can also be used for software upgrades.

2.3.4Auxiliary Data
