  3. For additional NXFM150 devices, connect a new run of RS485 wire between the first NXFM150 and the second NXFM150. This is called daisy chaining.

  4. The second and any additional NXFM150s will require an ID board. The second NXFM150 will want to have its ID board set to 1. If there’s a third NXFM150, its ID board would be set to 2, and so on.

  5. The daisy chain position of each NXFM150 will need to be set online. The first NXFM150 without an ID board is always position 0.

  6. The ID board plugs into the NXFM150 close to the pulse terminals:
