The AR-32P also provides DMX IN and DMX OUT 3-pin XLR connectors (Figure 4) for DMX recording,
control, and playback operations. Use only cable rated for DMX512 data transmissions.
Figure 4
Data cabling should meet the following USITT DMX512 specification requirements:
•
Low capacitance
•
Two twisted pairs
•
Foil or braid shielded
•
Suitable for use with EIA485 (RS485) operation at 250k baud
•
Characteristic impedance 85-150 ohms, nominally 120 ohms
•
24 AWG min. gauge for runs up to 1000 feet (300m)
•
22 AWG min. gauge for runs up to 1640 feet (500m)
Microphone cables and other general purpose, two-conductor audio or signal cables are not
suitable for use with DMX512.
