1.2 Connection Example
The diagram below illustrates how the Vi-K2/Vi-K3 is typically interconnected with other equipment.
Note:
•
All dome control by the Vi-K2/Vi-K3 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 Vi-K2/Vi-K3 may be used to control different
makes of domes. They may also be used to control the same make of dome.
•
If master/slave operation is required, all domes must be connected to the master Vi-K2/Vi-K3.
•
Multiple Vi-series Digital Recorders may be daisy chained. Each must be allocated a different unit
address (1, 2, 3 etc). Clock synchronisation keep dates and times of all units in step with the master
(Unit 1).
