external attenuator in the coaxial cable that is connected to the 935–940 FORWARD RF
IN port at the HU.
11. Subtract the value of the external attenuators from the total composite signal power (P
tot
)
and record the result. This value will be required when setting the attenuation of the HU’s
internal forward path attenuators.
2.4 Enter Site Name and Site Number
All HU’s and RU’s are programmed with the same site name and site number. 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 network. Use the following procedure to assign a unique site name
and number to each HU and RU system:
1. Click on the HOST Config tab and on the REMOTE Config tab. The HOST Config
