All HU’s and RU’s are programmed with the same site number and site name. It is therefore
necessary to assign a unique site name and site number to the HU and RU before they can be
connected to the same CAN. Use the following procedure to assign a unique site number and
name to each HU and RU system:
1. Click on the HOST Config tab and on the REMOTE Config tab. The HOST Config
