Connecting a Serial Device (Optional)
The encoder can be connected to a camera with Pan-Tilt (PT) functions or a PT Scanner (Pan-Tilt
Head) using the serial port connector. This allows the encoder to do pan and tilt using protocols,
such as Pelco-D, etc. Most PT devices accept protocol commands via RS-485 or RS-422
connection, which are both supported by the encoder.
Check the connection available on the PT device and connect it to the encoder following the
procedures below.
1. Map the wires from the PT device to the encoder using the supplied terminal block according
to one of the tables below.
Via RS-485 Connection
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.
