5 Basic Twisted Pair/RS485 Data Wiring
The Vision i Dome and VisionDome are capable of being controlled by either Coax Telemetry or Twisted Pair
Telemetry (RS485). Below are wiring configurations for two wiring formats used for Twisted Pair Telemetry
(RS485). The Visiondome VR camera is not RS485 end of line terminated, a 120Ω resistor across D+ and D-
must be used if the camera is fitted at the end of the RS485.
6 Visiondome VR Protocol/Address setup.
All Visiondome VR cameras are supplied set to 360 Vision protocol, camera twisted pair address 1. When
the Visiondome VR is switched on, an OSD (On Screen Display) is shown on the image from the camera for
approx 20 seconds.
PRO: Protocol being used for telemetry (e.g. 360 Vision Technology Ltd)
CAM: Camera RS485 ID (e.g. Cam 1)
S or L: Short or Long cable run. Use the utility to set whether the coax used to send video is under or over
300m.
Second Line: Shows the Visiondome VR Software Version loaded into the camera.
To change the above settings in the camera, 360 Predator utility software, a USB/RS485 cable (PRED-
USB-485) and a laptop are required.
The Predator utility and PRED-USB-485 cable drivers can be found on the CD (shipped with the camera) or on
the 360 Vision Technology web site (www.360visiontechnology.com/downloads).
Install the software (Predator-issued-120521-1-installer.exe) on the laptop being used. Connect the RS485 end
of the cable fitted with a 3 way connector to the Visiondome VR RS485. Run the utility on the laptop and then
connect the USB end of the cable into the laptop. The utility will then look for new comms ports and then will
look for the camera across all baud rates used.
Settings that can be altered from this software are:
•
Protocol: 360 (Coax/RS485), Pelco P 2400/4800/9600, Pelco
D 2400/4800/9600, Pelco Coaxitron (Extended version), VCL
(Coax/RS485), Ultrak (RS485), Forward Vision (RS485), BBV/
DENNARD C (FSK Coax), MARK MERCER (FSK Coax),
Molynx (RS485)
•
Coax Cable length: Longer than 300m or shorter than 300m.
•
RS485 Address: Used on RS485 systems only.
Daisy Chain
RS485 twisted pair cable is wired to each camera in a "chain". Only
the last camera is to have the RS485 (end of line) termination on, all
other cameras in the chain must have the RS485 termination off. See
Section 7 for the relevant product, termination switch settings.
Star Wired
RS485 twisted pair cable is wired to each camera in a "star" from one
point. A RS485 star driver/data distribution product must be used. All
cameras in this wiring configuration must have the RS485 (end of
line) termination on. See Section 7 for the relevant product, termina-
tion switch settings.
