NMEA 0183 PC OPTO-Isolator Cable, RS232 DB9 Female, Shielded (Isolated to PC)

Add isolation to an RS232 port to protect against ground loops. The OPTO-4 provides a safe and low cost way of connecting an RS422 (NMEA 0183) system to an RS232 (PC COM port) system, or any other device with a standard RS232 9-pin port.

The OPTO-4 provides comprehensive galvanic OPTO-isolation to protect the PC input/receiver, plus important spike suppression to improve the PC output/transmitter protection. Initially designed for systems wishing to receive NMEA 0183 data without the risk of ground loop damage, the flexible OPTO-4 can be used to interface any RS422 and standard RS232 connection, whilst powering itself from the RS232 port, making installation simple and very quick.

The Actisense opto isolator design integrates an over-molded case for excellent water resistance and a small footprint for installation into tight spaces.

Features:

  • One RS422 OPTO-isolated input
  • One RS422 (NMEA 0183) output
  • Up to 115200 baud
  • Port powered
  • Shielded cable and case
  • Protects PC input/receiver from damage
  • Water resistant cable.
  • Ruggedized over-molded case suitable for harsh environment
  • Quick and easy to install

Good shelves for the price can be challenging to install correctly
Size: 16 Inch, Color: White, Size: 16 Inch, Color: White
Good quality shelves for the price. Happy with the purchase. They give you assorted hardware to mount each shelf. Wall anchors for masonry or brick and anchors for drywall as well as screws to affix shelf to the wall bracket. The installation was fairly easy but it can be a bit difficult to get the bracket leveled on the wall. The “level” they give you is useless, it is only the tube - not in a housing, so 1 1/2” long. You will need a better level. Basically you place the bracket where you want the shelf to go then make sure it is level and take a pencil to mark the holes. We ended up using a heavier quality wall anchor so only needed 2 anchors instead of the four they send you. Once the bracket is on, slide the shelf onto the bars coming from the bracket and use the 2 set screws to secure it in place. Check for level and if it isn’t you can remove shelf and loosen bracket screws and wiggle the bracket while still attached while retightening screws. We had to re-level one of our shelves this way. Hope this helps and that it makes sense. As for weight capacity I wouldn’t want to put more than a couple of pounds on a shelf. As it is secure, it is hollow inside and too much weight would probably either cause the shelf to sag or damage your wall

Great shelves
Size: 24 Inch, Color: White
Easy to assemble and comes with everything you need for drywall or wood. Nice color and texture and comes with stickers to hide the holes underneath. I bought two sets of three. These are very long, so I recommend just using two at a time.
