I'm putting together a DH485 network for the first time. Mostly use Devicenet or Enet.

Components:

2 x Panelview 550 RS232(DH485) Comm Port
3 x 1761-NET-AIC
Micrologix 1100 PLC

Page 181 of Publication 2711-UM014F-EN-P show cables to use from PV to AIC.
It says for PV 300 - 1400, I can use a 2711-NC21 (Pins 7&8 crossed) no Null modem required or the older version 2711-NC13 (Pins 7&8 not crossed) which requires a null modem adapter.

Now on page 199 of the same publication there is a diagram showing the connection of a Micrologix PLC , PanelView 1000 to a AIC with a small NOTE!. It says "On PV 550 terminals, pin 8 on the RS232 connector is pulled high. Do not use the 2711-NC13 cable."

Does this mean that I shouldn't use the 2711-NC21 cable also since it also uses pin 8??
What would be the proper cable??

Thanks in Advance

Don't bother, After Several hours of searching I finally found a small note at the knowledgebase

that says I can use the 2711-nc21 but it 5 meters long. It also says I can use a 1747-cp3 cable with a null modem adapter with pin 7 removed.

Couldn't be easier
