System Interconnects
To aid simple installation KMS have produced several methods to connect system
components together. These are all based around the common RJ45 connector
allowing installers to either connect via a traditional screw terminal connector or
terminate using RJ45 plugs.
I2C2
This board is simply four RJ45 sockets and an 8-way screw connector. Uses include
but not limited to:
•
BUS connections between System controller and components.
•
One or two door DIN rail expansions.
•
Connecting outgoing BUS communications.
•
Connecting BUS readers
–
Note fitment of 12v fused link by KMS is required.
