Review: I had to cut this and re-splice two wires for a non standard RS232 Port wiring on my linear amplifier; TX and RX are not on the standard RS232 pins, so I was able to get an inside look. It’s well made, the cable and connectors are good quality. I have a good solid connection between my linear amp and the WaveShare Ethernet to RS232 adapter I also purchased on desertcart. It’s in a ham shack on top of a 1500 Watt linear amplifier and it has performed flawlessly for the week it has been in use even after my major surgery on the cable.

## Questions & Answers

**Q: Does this cable have all 9 pins connected straight through?  Or is it not a 9 wire?**
A: I had to cut this cable for an industrial application; it's 9 conductors (maybe 26 AWG) with a foil shield and drain wire.

**Q: Does anyone know the wire gauge or current capacity of the conductors?**
A: Hi, The wire gauge is 28 AWG.Let us know if you have any other questions.Thank you, StephanCustomer SupportStarTech.com

**Q: Are all the 9 pins wired?**
A: Yes they are. I just checked with my voltage meter for continuit

**Q: Does this serial cable work when connecting a computer to a digital projector?**
A: To expand more, this cable has 9 pins. VGA has 15 so it won't fit at all. I would recommend HDMI or DisplayPort cable for your use if both devices are capable. VGA is an outdated analog tech.
