Setup of the Intelligence Full-Dome Pan/Tilt
Before installing the product, first of all confirm the communication protocol and the baud rate of the main
machine in the system, then set the dip-switch SW2 of the pan/tilt to be identical with that of the system, set
the address of the pan/tilt on SW1 and the type of the communication protocol and the baud rate on SW2.
3.1 1. Terminal Resistor
:
The jumper JP1 is the option switch of 120
Ω
terminal resistor of the bus RS485. When it is at 2—3 state,
120
Ω
terminal resistor is opened and no bus 485 is connected; when it is at 1—2 state, 120
Ω
terminal
resistor is connected in parallel with the bus 485. In the bus RS485 system, there is only one pan/tilt, which
has the terminal resistor to be connected in the circuit and other pan/tilts whose terminal resistors are opened
so as to increase the reliability of the system. Generally, the terminal resistor of the pan/tilt at the farthest end
from the control circuit is connected and all terminal resistors of other devices are opened.

3.2 Dip-Switch of Address
:
SW1 is used to set the addresses of the pan/tilt which has the range from 1 to 1023. From DIP-10 to DIP-1 it
corresponds to a binary number with 10 bits in which the highest bit is DIP-10 and the lowest bit is DIP-1.
The state ON for each bit means 1 while the state OFF means 0. The encodes of some addresses are as
follows:
