Power and Data Connections
The fitted power and data cable is provided with bare ends to aid in installation, so please
ensure that care is taken in identifying the relevant connections and polarity.
Data communications to cameras and other devices is achieved via a two wire RS485
connection, and the data connection pins on the controlled devices will be labelled
appropriately with a “+” (positive) and a “–“ (negative) indicator.
Combinations of multiple control devices and multiple cameras may be connected together
using and Iris Data Expander.
Power your unit from a dedicated fuse / breaker rated at 12VDC / 500mA. The unit
operates when power to the breaker / fuse is applied. Ensure suitably rated cable is used
to handle the required current and voltage.
