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?

One thing that I found is that the RS232 is on Port 2 so presumably Port 1 is the RS485.

No, this powered serial device server box can't support IPV6, it supports IPV4.

Has anyone been able to power it via poe? i have a unifi poe switch that powers everything, but this device.

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. And here some files for your reference to use the adapter, https://app.box.com/s/i6y6on52q588huvukn1uz6dy162ossiq

/What is the operating temperature? there is no this important parameter. how can i buy it?

Hi, the serial to Ethernet adapter's operating temperature is from -4℉ to 176 ℉, relative humidity is from 5% to 95%.
