## Questions & Answers

**Q: Rs232 is working. however i can't get rs485 to work. i tried all different configurations and still couldn't get it work.any suggestions?**
A: One thing that I found is that the RS232 is on Port 2 so presumably Port 1 is the RS485.

**Q: Is IPV6 supported?**
A: No, this powered serial device server box can't support IPV6,  it supports IPV4.

**Q: Has anyone been able to power it via poe? i have a unifi poe switch that powers everything, but this device.**
A: Hi, the powered serial to Ethernet device server supports POE power supply, on pin 4/5 and 7/8 of POE switch. If any inconvenience caused, we're truly sorry for that, and if need any further assistance, you may contact us directly via the order page's "contact seller" button.
