Cable
There are two types of cables available, the four-wire cable and the two-wire cable (used only for the Modbus protocol).
The cable should meet the following specifications.
• Type:
Shielded twisted pair cable: 3 pairs 24 AWG or more (four-wire),
2 pair 24 AWG or more (two-wire)
• Characteristic impedance: 100 Ω
• Capacitance:
50 pF/m
• Total cable length:
Up to 1.2 km
Connecting to the VGA Connector (/D5)
CAUTION
• Connect the cable after turning OFF the DX and the monitor.
• Do not short the VIDEO OUT terminal or apply external voltage to it. If you do,
the DX may malfunction.
