the DC power applied to a remote FOL (fibre optic link) device. The battery load switch is designed for use with the complete range of point2point equipment. This allows the user to maintain a high level of shielding and isolation while being able to disconnect the remote FOL from its power source between tests. This can be used to significant improve the endurance of remote links operating under battery power. The battery load switch is compatible with all point2point shielded FOL and can be retro fitted to existing systems, in place of the U Link. The battery switch controller can be fitted into the full range of point2point cases and converter sleeves, including all existing systems. This handbook covers the following point2point variants:  73680 Switch, Battery Load, point2point  73681 Module, Battery Controller, 4 channel

This section describes the connections to your Battery load switch and controller. When used with the point2point shielded FOL, the battery switch should be connected with its “battery” port connected to the output of the shielded battery pack and its “module” port connected to the shielded FOL battery input. Failure to connect the battery switch correctly will result in the unit being permanently on, with approximately 1V of voltage drop between the “module” and “battery” connections. With the optical input unconnected the default state of the switch is off. The optical input should be connected using an ST multimode cable to the battery switch controller. Each of the four outputs of the battery switch controller can be used to control one battery load switch. The diagram below shows the connections.

For illustrative purposes only; control module normally resides with receivers in a suitable PPM 19” rack case) 2.1 Battery Load Switch The battery load switch contains a fibre optic receiver which senses the presence of a light source. With the light on it will switch the DC circuit on, allowing conduction between “battery” and “module” ports with a very low resistance. With the light off these ports are isolated, with very high impedance between them. It is housed in a fully shielded unit. The ground connections for the battery and module are common and not switched. The module and battery ports are DIN47295 1.6/5.6 socket connectors, with spacing compatible with the battery U linking plug 55733. The fibre optic control port is ST multimode; it can accommodate a wide range of fibre types including 62.5/125um and 50/125um.

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. 2.1.1 Signal connections Battery port DIN47295 1.6/5.6 Socket DC power input, outer ground, inner +Vin Module port DIN47295 1.6/5.6 Socket DC power output outer ground, inner +Vout Optical port Optical ST connector Multimode optical control fibre 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.
