Nodes 5-37
햽
External BNC Antenna
This antenna should be connected to the BNC connector for optimum performance.
햾
On-board antenna link
When the jumper is across this link, as illustrated, the on-board 1/4 wave whip
antenna is utilised. On the BNC external antenna node, this jumper should be removed.
햿
Power supply and current consumption
Current Consumption - Quiescent State: 100mA, Maximum:
200mA.
헀
Ringnet communications
Nodes should be wired in a ring configuration, as illustrated. The maximum
permissible distance between nodes is 1Km (using Belden 9829). The interface uses RS485 in a ring topology. The
main controller therefore has two RS485 ports and completes the ring connection – see the following connection
diagram and cable type table.
Node Cabinet
This node has the same cabinet as the 8 Input/Output Node – see “Node Cabinet” on page 5-17 for details.
Additional Information
Method For Optimising RPA Performance
●
Fit an external antenna onto the HUA node if not already fitted.
●
Move the HUA node to a location where the signal strength is maximised as described in the following RPA
installation test procedure.
