1V(p-p, 75
Ω
). When using RG-59 cable the maximum, trans-
mittance distance dose not exceed 300m.
3.
The RS485 lines of each dome camera must be connected
to the RS485 contro l BUS of the matrix. The polarities in the
connection must be correct (refer to Picture 6-7 for polarity
indication);
4.
The dome ID address must be the same with its video input
port number of the matrix (the numbers are silkscreened on
the back panel ofthe matrix). For example, when one dome
