This review is from: StarTech RS-232 to RS485/422 Serial Converter (IC485S) (Personal Computers)

Tried to use this to connect a PC's serial port to a RS-485 device. Sometimes this device would allow communication one way, and sometimes it would allow communication the other way, but we could not get it working reliably after about a week of fiddling with it.

In contrast, one of the other adapters that we tested (which cost $99) worked very reliably without any trouble (so it wasn't a problem with the cabling, the PC, or the RS485 device). Overall I would not recommend this product as it was very unreliable for us.

I am completely satisfied with this transaction and I saved about 250.00 from what the bulb is through in focus.
No issues what so ever and delivery was earlier than stated by a day

The only issue I had was with the instructions. They are vague (to me anyway) when it came to use of the switch positions' functions. Could be my unfamiliarity with serial communications. And certainly not something that should dissuade purchase.
