LAN connection (D+ and D
–)
The RAS is connected to the Challenger panel via the RS-485 LAN, up to 1.5 km
cabling distance from the Challenger panel unless LAN isolation devices are
used to extend the distance).
We recommend that you use 2-pair twisted shielded data cable (such as Belden
8723) for the RS-485 LAN.
• D+
is the data positive connection of the LAN data bus.
• D–
is the data negative connection of the LAN data bus.
LAN cable shield
The LAN cable shield must be connected to system earth at one end only. If the
LAN is ‘daisy-chained’ to the RAS, ensure that the shield of the cable is jointed to
provide continuity of data cable shield.
Power connection (+12V and GND) to Challenger panel
The RAS can be powered using the RS-485 LAN + and
– power from the
Challenger panel, if the cabling distance does not exceed 100 m (if using Belden
8723) and when electrical isolation is not required.
Power connection (+12V and GND) to separate power supply
The RAS can be powered by an auxiliary power supply.
