The monitor must be configured as EXT. 1, 2 or 3 (see instructions for see-u WIFI or NO WIFI monitor) and the last monitor installed in terms of wiring, the one furthest away from the outdoor panel, will have to have a jumper on the back configured as the end of the line. The dipswitch 1 in ON.
If the installation already had a monitor installed before the extension and this one will remain in the installation as an intermediate one, we will have to change DIPSWITCH 1 to OFF as only the last one has to have the end of line jumper.
