The Actisense OPTO-4 is a bi-directional NMEA 0183 (RS422) to RS232 interface cable which provides a safe method of connecting an NMEA 0183 system to a laptop PC or any device with a standard RS232 9-pin port. The isolation protects the connected device, so any potentially hazardous voltages on the NMEA 0183 bus do not cause damage to the PC hardware, offering the user complete peace of mind.
The OPTO-4 is particularly suited to 'noisy' or commercial environments, as it provides a complete solution for system builders who require all components to be shielded. As it is port-powered (from the PC), the OPTO-4 is quick and trouble-free to install.
The unique Actisense design integrates an over-moulded case for excellent water resistance and a small footprint to ease installation into tight spaces.

- Overmoulded case with a narrow profi le for installing in small spaces
- Transient protection on the PC output line
- Opto-isolation providing 2000 volt protection on the PC input line
- Reverse voltage protection on the PC input line

Amazing product!
Color: White, Size: Standard, Color: White, Size: Standard
I love this item so much, it makes my wires super organized and it holds them well. The white appearance goes cleanly with my white desk frame, and the size is perfect to fit a lot of wires. It has amazing functionality and comes with 2 screws. I do recommend pre drilling holes so you do not ruin your desk, and ensure that your desk is thick enough that the screws won’t pierce through.

Sleek, Sturdy, and Matches My Desk Brand Perfectly
Color: Black, Size: Standard
Great on-brand cable management tool. Honestly, I only bought it to match my desk brand—cable management is cable management—but I’m really glad I did. It looks solid, feels high-quality, and the metal construction adds a nice sleek touch under the desk. Clean, minimal, and functional.

Works great, easy to install.
Color: Black, Size: Standard
Does exactly what it’s supposed to do and comes with screws. Installation was easy once I drilled pilot holes and used a screwdriver. The only downside is that a longer drill bit would have made the process easier, but that was on me for not checking beforehand.

Simple solution for a cleaner desk
Color: Black, Size: Standard
This cable management tray made a big difference in cleaning up the mess of cords under my desk. It’s sturdy, easy to install, and holds a power strip and extra cables without any problem. Once everything was in the tray, the area under the desk looked much more organized.
