APPENDIX C
MP168 Matrix Switcher/Controller System
For maximum distance, attach the repeater J-Box at a point where the signal level has reached 1-2v (peak-to-peak). This
takes advantage of the prior host’s driver capabilities, while providing a strong signal for amplification.
No more than 3 repeaters should be used in series between any two network devices, as this can create signal distortion,
and cause operational errors.
Network Topologies
SensorNet supports three network link topologies: daisy chain , backbone , and star . Each network link can be wired to
apply the topology that best suits the link’s unique requirements.
Daisy Chain Link Guidelines
With a daisy chain network link, a separate cable connects each device to the next device in the chain. This facilitates
quick and easy installation.
The daisy chain is a good solution for a temporary network, or where the host and a few devices are located in the same
room or area.
Consider using a backbone or star topology when installing large and permanent networks.

Figure C-3 - Daisy Chain Link
1. Terminate devices at both ends of the daisy chain. Leave all others unterminated.
2. Attach up to 32 devices on each link.
3. Limit combined cable length (from CCM to farthest device) to 1 km (3281’) or less.
