upgrading panelview 550 to PV600

Hello I have an older panelview 550 which is on a 5/04 processor connected to a 1761-AIC-NET, DH+ on port 3 from processor, port 2 to the panelview 550, what cable is needed to use the panelview 600 plus, I have all my comms set up on the panelview but I get no communications.
Please help!!!!

Hi

Is it the serial port you are connecting to ?

Donnchadh

yes it is

I think the cables are the same. Probably need to re-check on the panelview config screen that the panelview and the plc port2 comm settings match. You might want to post the exact part numbers on the 550 and 600.
