Serial Port Connection
The zoom camera can be connected to a
Pan-Tilt (PT) Scanner
(Pan-Tilt Head) using the
serial port connector. This allows the zoom camera to do pan and tilt using the Pelco-D
protocol. Most PT scanners accept Pelco-D and Pelco-P protocol commands via RS-485 or
RS-422 connection, which are both supported by your camera.
Check the connection available on the PT scanner and connect it to your camera following the
procedures below.
1.
Map the wires from the PT scanner to your camera using the supplied terminal block
according to one of the tables below.

NOTE:
The pins of the PT Scanner may be labeled differently depending on the location or
country where the scanner is purchased. For example, some devices may have RS-485
DATA+
pins labeled as “TX+”, “RX+”, "A” or “485+”, etc. Refer to the scanner
documentation or contact the manufacturer to verify the corresponding pin labels and
ensure proper wiring connection.
CAUTION:
Incorrect wiring may cause damage to the connected devices.
DISCLAIMER:
ACTi will not be responsible for any damage caused by improper wiring.
2.
Connect a ground wire to one of the GND terminal pins of your camera (via Power or DI/O
terminals) to complete the connection.
