Good morning,

I have a SimoCom 611-U system that I'm trying to go online with using SimoCom U over RS485. 

Power Module: 6SN1145-1AA01-0AA2

LT Module: 6SN1123-1AB00-0AA1

Digital Control Plug In Unit: 6SN1118-1NH01-0AA1

I'm using SimoCom U Version 14.03.02

I've verified my comm port and serial converter cable driver.

I found in the SimoComU help that I need to change parameter P0801 to RS485, and I did that procedure.

When I try to "search for drive online" it doesn't find anything. What could be wrong? 

I notice that the install file for SimoComU V14.03.02 comes with 2 folders of device drivers.

"SDD08040900" & "SDD09020001"

Do I need to run those executables separately?  

ThankYou! The RS 232 worked. I used:
