• Generates ±5 VDC, +3.3 VDC, and +28 VDC.
• Generates the time varied gain (TVG) curves for the received
sonar signals from the transducers.
• Multiplexes all the data channels and transmits the telemetry back
to the surface.
• Provides cable uplink and downlink interface, as well as electrical
output for external fiber uplink.
200 VDC is indicated by bright orange LED D40. The voltage can be checked at
JP8. The +5 volts is generated by a switching regulator and indicated by green
LED D37. The voltage can be checked at L37. TPGND1 provides a ground
reference. A second switching regulator generates -5 VDC, indicated by green
LED D38, and measurable at L30. A third switching regulator gen3.3
VDC, indicated by green LED D39 and measurable at L26. (Be sure to measure at
the output side of L26.) +28 VDC is generated by a fourth switching regulator,
which can be measured at TP25. Use TPGND8 for ground reference. A linear
regulator generates 2.5 VDC from the 3.3 VDC source. This is indicated by green
