4125 SIDE SCAN SONAR SYSTEM 0004823_REV_F
3.2 Power Requirements
The power requirements for the 4125-P Portable Topside Processor are 90–260 VAC, 50/60 Hz or 12–24
VDC.
3.2.1 Use of an Uninterrupted Power Supply
The AC power source should be continuously free of high-amplitude, high-frequency transients, as this
type of interference could cause degraded performance or damage to the equipment. An uninterruptable
power supply (UPS) with power surge protection is recommended for powering the equipment.
However, whether or not a UPS is used, never use an AC power source that also powers electric motors
on the survey vessel, such as pumps and winches. In addition, do not use switching type battery chargers
or DC to AC converters with square wave outputs.
3.2.2 Changing a Non-US Power Plug
An AC power cord is provided for connecting the Deck Unit to a standard U.S. 3-pronged outlet. For non-
U.S. power outlets, modify this cord by cutting off the 3-pronged plug and attaching the appropriate plug.
Refer to TABLE 3-1 for connection information.

NOTE: The 4125-P Portable Topside Processor is shipped configured for
the end user’s country voltage requirements.
3.3 Navigation Interface
The 4125 Series Dual-frequency Side Scan Sonar System accepts all standard National Marine Electronics
Association (NEMA) 0183 message sentence formats from a connected global positioning system (GPS) or
integrated navigation system.
