Hi there. I have panel view 550 keypad . Part number 2711-k5A5 has communication port rs-232 phisically it's protocol dh-485 . Can I replace it with other one has communication port rs-485 phisically it's protocol dh-485 . It's connected to SLC 5/04 through the serial rs- 232 port (Cho) on processor module by straight forward cable with two d-shell type 9 pin sokets in the two sides .The new panel view had rj-45 communication port . What can I do to connect it with SLC 5/04 in the same protocol dh-485.
i think i must make new straight with rj45 soket in side . And the other side will be d-shell type . And edit the hmi program on panel builder soft to change the model .and download it .is that true or false?
Thanks in advance.
