Rnet Configuration

You wire SPT sensors to a controller's Rnet port. An Rnet can consist of any of the following combinations of
devices wired in a daisy-chain or hybrid configuration:
• 1 SPT Plus, SPT Pro, or SPT Pro Plus
•
1–4 SPT Standards
•
1–4 SPT Standards, and 1 SPT Plus SPT Pro, or SPT Pro Plus
•
Any of the above combinations, plus up to 2 BACview
NOTE You must set addresses only on the following Rnet devices:
•
SPT Standard sensors if you have more than one on the Rnet. See To address an SPT Standard sensor
(page 5).
•
BACview

To address an SPT Standard sensor

If the Rnet has multiple SPT Standard sensors, the first sensor retains its default address of 1. You must give
each additional SPT Standard a unique address on the Rnet. To set the address:
Pull the back plate off the sensor, pulling from the bottom first.
1
Remove the two hexagonal screws that attach the circuit board to the cover plate.
2
Remove the cover plate.
3
On the circuit board, set the address jumper to 2, 3, or 4.
4
Attach the circuit board to the cover plate with the hexagonal screws.
