I have a Micro820 here that will eventually be used as a slave device and will have information pulled from it serially. I need to test the Micro820 with Modbus Poll or similar software (that simulates a master device) to make sure this will work.
In order to do this I am using my desktop computer, a USB > DB9 and then wiring straight into the onboard serial RS232 terminals on the PLC.
Basically, I'm following this guide here, and it should be noted that I've tried two different cables (one of which I've confirmed works for LOI connection to a different PLC, and the other that's brand new):

My problems begin when it comes to configuring the drivers for the device. Auto-configure elicits an error response:

Even when I set this up manually, to match the settings in device manager and CCW (matching the baud, parity, etc), I get a timeout error in Modbus Poll and any other Modbus master simulation software.
I don't know where to go from here honestly and I'm just at a complete loss. Been fighting this for two days now and any help is super appreciated. I'm completely new to this and could use any insight.
Thanks ahead of time.
