JB70E2-SA Electronic and transceiver unit; This unit is the echosounder producing the acoustic signals and processing the returns to give the appropriate outputs for depth. It contains connections for 2 transducers, 2 LAN ports for connection to the bridge or control units, auxiliary inputs and outputs, 5 NMEA outputs and 3 inputs, and power input 24VDC and 110-230VAC. This unit is mounted on or close to the bridge, with long cables coming from the transducers.
If 7 outputs is not enough, the NMEA will typically be sent to a splitter/Expander such as the
SKIPPER NE108-SA to give the information to the bridge/alarm system and VDR.
