Performance specifications
These performance specifications summarize the main functional and operational characteristics of the M3 Sonar system.
•  Slant range: 0.2 to 150 m (depends on model)
•  Coverage: up to 140°
•  Range resolution: 1 cm
•  Frequency: 500 kHz to 1400 kHz (depends on model)
•  Pulse types: CW, LFM
•  Communication: Ethernet
•  Data Rates: 10/100/1000 Mbps
Synchronization
•  PRI Synchronization (master / slave operation):
–  Sync Input: 0 to 5 VDC, hold-off when high
–  Sync Output: 0 to 5VDC active low pulse 100μs
•  1PPS Synchronization
Note
The selection of sonar applications presented in the Sonar Applications menu depends on the current Sonar Head frequency. The M3 software will automatically detect the frequency of your Sonar Head and display only the applicable sonar applications.

VDSL
Firmware version: 1.5
Part number: 320-27701000-0150 (Rx controller)
Important
Although VDSL sonar heads are pre-programmed at the factory with the correct firmware, you may need to upgrade your firmware if you do not have the latest version for your VDSL Sonar Head. For the best performance, firmware version 1.5 (or later) is required for applications using a long cable and VDSL telemetry. Note that you only need to upgrade the Sonar Head receive firmware file (.RXF) and the Sonar Head software file (.ASW). You do not need to upgrade the Sonar Head transmit firmware file (.TXF).
