Distributed video switching using a VisiWire or PCCON
network
9.6.1
Setting the node address
Siemens Building Technologies

You can connect up to 127 nodes, made up of a mixture of VIS3I-328 units,
together to form a distributed video switching matrix using the VisiWire or PCCON
network system. You make the video connections between the nodes using coaxial
cables, or other third-party video transmission systems.
A keyboard at one node may view and control devices at any other node,
specifically cameras, VCR/DVRs and multiplexers. It may also respond to alarms
from other nodes (VisiWire only).
When networking nodes it is recommended that any video sequences are
performed on the local node as opposed to sending multiple requests over the
network as network congestion could occur.
Each node on the network must have a unique address between 1 and 127.
Setting other addresses takes the node offline or sets special modes.
You set the address of a single-unit node using the two rotary hexadecimal
switches on the rear panel. The left rotary switch sets Sixteens and the right switch
sets Units.
You set the address of a dual-unit expanded node using the Master unit address
switches.
To convert between decimal used in VisiPC and hexadecimal for the switches, use Tab. 19:
