1 PRODUCT DESCRIPTION
Electronic circuitry in the Bay Tracer sensor checks for a change in current on one or more
–48 Vdc power conductors on the DSX-1 or DSX-3 fuse panel caused by an individual jack
insertion on the far end bay and uses this change to activate an LED. The change in current is
detected by a clamp-on inductive pick-up coil encircling the –48 Vdc power conductor(s)
attached to the DSX fuse panel of the device being monitored. A two-conductor 8-foot (20.32
cm) trailing sensor cable attached to the inductive pick-up coil is used to transmit a signal to the
sensor. A customer supplied two-conductor (–48 Vdc and battery return) power cable is used to
transmit power from the fuse panel on the back of the DSX-1 or DSX-3 bay to the sensor.
