APPENDIX1
Master/Slave operation (Controller specific)
The DCI range of controllers come with the factory specified option of being able to link more than
one controller via a fibre optic cable.
This allows 2 or more controllers to be operated together from one single handset. The maximum
length of fibre optic cable which can be used is 20.0m, this denotes the maximum distance you can
have between 2 controllers. Applications include ‘topping and tailing’ train configurations and also
very high power, multi motor, locomotives.
When the second controller is set to slave, it is controlled, via the optical link, by the first ‘master’
controller which is controlled by the handset.
The fibre optic cable is the ideal way to connect the controllers, there is no electrical connection
between the 2 controllers and no wires to damage or short out.
If the optical cable is broken, the slave controller will revert to neutral and freewheel until you can
stop and repair/replace the cable.
APPENDIX2
Auxiliary switched outputs
The DCI controller has up to 4 auxiliary switched outputs. These connections are controlled by the 4
switches on the handset.
