Power Requirements
The basic over the side installation of the Sonic 2022 and 2024 systems consists of the sonar head,
projector, SIM box, sound velocity probe, and interconnecting cables. The sonar head, SIM, and
computer(s) communicate via 100BASE-T or 1000BASE-T (Gigabit) full duplex Ethernet.
Installation in an ROV requires an Ethernet media converter to convert copper to fibre optic and
back to copper media to accommodate long tethers. On shorter ROV tethers (less than 1000
metres), using impedance controlled twisted-pair copper wire and a DSL modem may be possible.
Remote or autonomous vehicles typically supply the 48 volt power to the sonar head, and if
required, the SIM Controller board.

Table 14: Systems Power Requirements
In an ROV or AUV installation, the sonar head and SIM Controller board require 48VDC which is
supplied by the vehicle power system. The average power required is 50 watts for the 2024, 35
watts for the 2022. Just after transmit, an additional 50 watts is required to charge the transmit
capacitor bank for a brief period of time. See below figures for current waveforms. If a separate
power supply for the sonar is required, it should be rated for 120 to 150 watts or higher.
