Configuration options

Housing selectionModel variants

This page describes the MT-Series 1000 m housing. Other depth ratings are separate models with different mass and electrical specifications.

Ethernet / DSL integrationInterface

4-wire 100-BaseT Ethernet; a 2-wire DSL extender module is listed by the manufacturer.

Compatibility: Oculus MT-Series; confirm cable pinout and power arrangement for the selected installation.

Acoustic performance notice

Maximum range, range resolution and frame rate depend on the selected frequency and operating range. Depth rating describes pressure capability, not acoustic reach. Values separated by a slash correspond to the frequencies in the same order. Mechanical and selected electrical/acoustic discrepancies are identified in the specifications below.
