I using USB to DH485 Interface converter to connect the panel view 600 touch screen , and I had to make a RS485 cable with RJ45 jacket but I can't find any detail about RS485 with RJ45 connector because most of the source giving different data. So does any standard pinout for RS485.

Good luck with this... you will have better luck making a serial to DH485 (AB part number 1747-PIC)

USB to DH485 is not easy... well getting it to work is not easy, you will be better to buy the 1747-UIC

You may want to search the part number to find the pinout

Post the complete part number of the PanelView.

Rockwell uses DH485 which is not the same as RS485.

What are you trying to connect to the PanelView using the USB to DH485?

My panel view part number is 2711-TC62L1
and I using 1747-UIC to communicate with computer.
 
Ya, I am using 1747-UIC. I switch to the RS485 (DH485) and I had online search about the RS485 pinout, but there are many different pinout of RS485.
In the manual had suggest 1747-C13 cable, there is a straight cable like Ethernet.
So if I using straight Ethernet cable will it work?

Don't use an ethernet cable. See PDF below for a pin-out of the 1747-C13 cable.

I had tried a straight cable, but on RSlinx only shown the 1747-UIC device and the led on that device only shown USB and OK light, DH485 did not respond.
 
Does the Panelview have an RS232 port? Have you tried connecting to the PV using this port?

The RS232 port can be set to DF1 or DH485.

2711-NC13 is the cable required for this (same for DF1 or DH485), which is just a standard "straight through" serial cable.

If it's set for DF1 you just use standard USB > serial adaptor, if it's set for DH485 you will need to use your 1747-UIC.

Edit: Actually ignore the above, after researching the manual it looks like that model only has an RJ45 port?

Here's a manual for reference: http://literature.rockwellautomation.com/idc/groups/literature/documents/um/2711-um014_-en-p.pdf

Baud rates must match and node addresses must be different.

Do you know the comm port number your 1747-UIC took on your PC?
