The unit has two RS-485 ports on the rear panel. You can connect multiple PTZ devices in a daisy chain from either port. Be sure to disconnect
power from any camera before connecting its data leads to the unit.
To connect the data leads from a serial PTZ device to the unit:
1. Using a small screwdriver (or similar tool), push in the TX– wire retainer on the first data port on the terminal block.
2. Insert the RX– data wire from the PTZ device into the TX– retainer.
3. Push in the TX+ wire retainer on the first data port on the terminal block.
4. Insert the RX+ data wire from the PTZ device into the TX+ retainer.
5. To connect a PTZ device to the second data port, repeat the previous steps, as necessary.
6. To connect additional PTZ devices in a daisy chain, refer to the documentation supplied with the PTZ devices.
NOTE: Maximum distance for serial communication lines is 1,219 m (4,000 ft) between the DX4700/DX4800 and the last PTZ device on the daisy
chain.
