Up the Coax Configuration
Up-The-Coax PTZ control
Commands to control the position of the dome can be transmitted up the same co-ax cable used to
transmit the video signal to the recorder station. Different controllers require different protocols and
two switches are provided to select the desired protocol. These are accessed by removing the outer
hemisphere,
refer to Switch Configuration for more information
.
Switch settings
The switches are color coded, blue and yellow, and are located inside the dome camera housing.
Configure the switches for the controller being used as shown in table below.
Up the Coax Switch Configuration
The switches are factory set to FD (DM up the coax control).

RS485 Serial Connection
The coax cable and power wires are always connected.
The RS485 wires are only connected when an RS485 controller is being used.
The dome supports a range of serial RS485 PTZ protocols. The desired protocol and the node
address for the dome are selected by the two rotary hex switches (blue and yellow) inside the
dome. These are accessed by removing the outer hemisphere and inner shroud, refer to Switch
Configuration for more information.
The switch settings for the protocols and node addresses are shown in the table below.
To use the table;
1.
Select the protocol required
2.
Select the node address of the dome to be configured.
3.
Scan across the table to identify the values for the blue and yellow switches.
For example, if the dome is to be used with a Dedicated Micros PTZ controller system with address
ID#5 the switches should be set to ‘05’. i.e. the blue switch should be set to ‘0’ and the yellow switch
set to ‘5’.
The dome will display its switch setting when first powered on as the screen will show (in the
example above) “CAM 05”.
