How to connect PTZ decoder
a. Ensure the decoder has the same grounding with DVR, otherwise you may not
control the PTZ. Shielded twisted wire is recommended and the shielded layer is used
to connect to the grounding.
b. Avoid high voltage. Ensure proper wiring and some thunder protection measures.
c.
For too long signal wires, 120Ω should be parallel connected between A, B lines on
the far end to reduce reflection and guarantee the signal quality.
d.
“485 A, B” of DVR cannot parallel connect with “485 port” of other device.
e. The voltage between of A, B lines of the decoder should be less than 5v.
4.
Please make sure the front-end device has soundly earthed.
Improper grounding may result in chip damage.
