• RS485 Termination

If Robo PTZ is using RS485 communication, please make sure the Bus is correctly installed and configured
to prevent malfunctions. The maximum allowed cable distance is 1200 metres. A Maximum of 32 units
can be connected to a cable section.
Any cable type which exceeds the specification of EIA RS485 can be used. The furthest device, by cable
length, should be terminated in accordance with the specification. Other devices should remain un-
terminated (see Figure 11 below).

• Keyboard Operation

Key Sequences and Joystick movements are executed to closely control the camera and program the
Telemetry Control system of Robo PTZ. Examples of these are PRESET and TOUR.

If a Keyboard cannot be used to access and change the camera parameters, most characteristics are
accessible through the camera’s OSD menu.

Note – Changing a Keyboard’s Software and/or Protocol can effect alterations to the camera’s
operability. The Robo PTZ manufacturer absolves itself of responsibility for such modifications.
