1.2 Connection Example
The diagram below illustrates how the VK-2 is typically interconnected with other equipment.
Note:
• All dome control by the VK-2 is via RS485 twisted pair.
• Supported domes, which have RS485 twisted pair control, may be connected directly as shown.
• Domes, which only have coax control, require a protocol converter, also shown.
• The
“
DOMES-1” and “DOMES-2” outputs from the VK-2 may be used to control different makes
of domes of any type. They may also be used to control the same make of dome.
• If master/salve operation is required, all domes must be connected to the master VK-2.
• Multiple Digital Recorders may be daisy chained. Each must be allocated a different unit address
(001, 002, 003 etc). Clock synchronisation may be selected in VDMs to keep dates and times of all
units in step.
