USB to RS485 Adapter
Simple to install, does the job
This review is from: SEDNA - USB 2.0 to RS485 /422 Adapter
Pros: Very easy to install, drivers installed properly first time. Very compact. I use this to check connectivity on badge scanners for time clock systems in the field, so smaller is better. Set-screw connections make solid connections and appear to be durable. The activity light really helps diagnose connection problems.
Cons: The red "on" LED is so bright you can't see the green activity LED come on unless you cover it up! They either need to use extra-bright LED's on both of them or standard ones.
Other Thoughts: Haven't used this a lot, but it really helped out on the first job I took it to.
