MicroTTU

The microTTU is a compact subsea serial multiplexor that turns one ROV serial channel into six additional channels for added comms on ROV, AUV, or towfish operations. It is built for harsh subsea use and is depth rated to 4,000 m. Data multiplexed subsea is available topside on a physical COM port or as a virtual COM port for other applications.

Each sensor port is fully configurable from the surface with independent baud rate and parity, and settings stored in NVRAM. Operators have transparent control of sensors, plus software and hardware break commands. Data can be appended with precise time tagging or passed through unchanged, and the surface software can log individual channels to separate files.

Configuration options include six RS232 channels or a mix of four RS232 and two RS422. The uplink is normally RS232, with RS422 or RS485 available for long hard-wired use. Key specs: input 16 to 30 Vdc, about 2 W for the unit, up to 100 W available for sensor power, depth rating 4,000 m, connectors MCBH8M (uplink) and MCBH16M (sensors), length 305 mm, diameter 50 mm, weight 2.6 kg in air and 2 kg in water.
