The control circuit draws its power from the input power source, but the load is relatively low and hence does not
significantly impact the battery endurance. The switch is directional, the power source must be connected to the
battery port and the load must be connected to the module port. It is designed for use with a centre positive power
source (ie the centre pin is at a higher voltage than the outer case).
The unit is specified for operation with a 14.4V nominal battery pack when operating with PPM point2point shielded
FOL. Operation is also possible as a stand-alone unit with a wide input voltages range, see specifications.

2.2 Battery switch controller
The Battery switch controller is design to fit in any standard point2point rack or converter sleeve, it has 4 optical
outputs and can be used to control four Battery load switches.
All the optical outputs are ST multimode and can accommodate a wide range of fibre types including 62.5/125um
and 50/125um.
The optical output can be manually controlled via the front panel push switch (with all control inputs open circuit).
This switch toggles the output, where green signals that the output is on, and red that the output is off.
2.2.1 Control Signals
The output can also be individually electrically controlled via the front panel 8 way connector. When the status is set
to on (front panel LED green) the individual outputs will be on if their control connection is high, or off if there control
connection is low. When the status is off all the outputs will all be off regardless of the control signal connection
status.
Low = Short circuit (<100Ω) or Voltage < 0.8V
High = Open circuit (>100kΩ) or Voltage > 2.0V
2.2.2 Signal connections
Control port: shrouded 0.1" 8way double row
Note: A mating cable is supplied for this interface fitted with 0.25m of cable (73682)
Note: Pins 6, 7, 8 are not intended for external use and should not be connected
