RJ45 Adaptor
A single RJ45 socket with screw connectors. KMS included these with the one and
two door DIN rail systems. Each board has fly leads connecting Lock Controllers and
Reader Interfaces together, the RJ45 is then used to connect to the system controller
or I2C2.
Where one or more Lock Controllers are connected using the RJ45 adaptor, power
must be provided directly from the PSU using BUS terminals 6 & 8 on the Lock
Controller.
An ethernet patch cable is
not
able to supply adequate current for locks and this
should be taken into consideration by the installer.
