Addendum
If the user selects thinner cables or installs the camera in an
environment with strong electromagnetic interference, or connects
lots of equipment to the RS485 Bus, the maximum transmitting
distance will be decreased. To increase the maximum transmitting
distance do the opposite.
2.3 Connection and termination resistor-
The RS485 standards require a daisy chain connection between the
equipment. There must be termination resistors with 120 Ohms
impedance at both ends of the connection. (refer to Figure 37). Please
refer to Figure 38 for simple connection. 'D' should exceed 7 metres.
