Configuration - urmet 1092/602 Bedienungsanleitung

CONNECTIONS
• Connect the provided cable to the dome using terminal blocks.
• Connect the second end of the cable to the video device, using the BNC male connector.
• Connect the two wires of RS485 with a terminal block or welding them to the keypad (Ref. 1092/620)
wiring junction box, observing polarity: ORANGE + (positive) - YELLOW – (negative).
• Connect the two power supply wires with the terminal block or welding them to the wires of the provided
power supply unit (it is not necessary to observe polarity).
• If the dome is the last device of RS485 line (see RS485 LINE LOGIC CONNECTION), connect a 120
Ohm ¼ w resistor, not provided, in parallel to the RS485 line.
• Make connections as shown in "CONNECTIONS DETAILS".
• Connect the power supply unit to the mains.

Note
If several Domes are connected, it is suggested to use a cascade configuration, with "in/out" connections on
each device. However, the sum of the lengths of the single segments of the RS485 line must not exceed
1200m.
Remember to always connect the termination resistor on the last Dome of the line.
