PTZ Control:
11. If PTZ Control is to be transmitted to the camera, verify that the distance
between the camera and the hub is within the distance specifications for
sending PTZ control over twisted pair. Consult the PTZ equipment vendor
for maximum distances. Please ensure that the port switch is set to Pass-
Thru Mode (500022). When the port switch is set to Pass-Thru Mode
(500022), one (1) twisted pair is used for PTZ control. For optimum
results, it is recommended to use control protocols such as RS-422, RS-485
or Bi-phase. Due to crosstalk issues, RS-232 is not recommended.
12. Connect two (2) wires between the PTZ controller and the “Control”
terminals on the hub (fig 17).
