1.1.4 Dome Control
• The VK-2 has two dome outputs “DOMES1” and “DOMES-2”.
• A particular VK-2 can be connected to a maximum of two different types of dome; all of one type
must be connected to the “
DOMES-1” output, and all of the other type of dome must be connected
to the “
DOMES-2” output.
• Each camera (up to 256) must be assigned to use one or other of these outputs (the factory default
assigns all cameras assigned to “
DOMES-1” output).
• Each of the two dome outputs is assigned a dome protocol.
• The domes may be either daisy-chained. In this case, turn the termination off on all domes except
the last in the daisy chain, which should have its termination set on.
• The dome may be connected in “star” mode by means of a RS485 “star expander” (our product
code “VX Hub”). In this case, all domes should have their termination on.
• Each dome must be set up with an address that corresponds with the camera input to which it is
connected (i.e. addresses 1, 2, 3 etc for domes on camera inputs 1, 2, 3 etc)
