Setting up Sony SRG X120 X400 cameras with RM-IP controllers

This is a kind of high-level setup of X120 cameras.  

Essentially:

Cameras will need to be accessible from the IP network as the controller.  You can  HTTP to each camera's ip address and lock in an IP address.

Then use the IP controller app SONY PTZ SRG-X120 - Google Drive called "RM-IP" 

Make sure that you have the cameras setup into group and with unique names.  The group number coincides with the RM-IP10 controller.

On the controller itself there are two rows of DIP switches.  Bottom row, #8, you set to on to allow writing.  Power cycle the controller, the lights on the controller will blink continuously.

Go to the RMIP app, and you should be able to select the controller (assuming all on same network).
under "CAMERA TABLE" what I do is select the spots that I want to occupy a camera, then use "AUTO ASSIGN" then assign the IP range(s) of the cameras I want.

Apply it, and then once you have done that.  Flip the switch 8 on the controller back to normal position and power cycle it.  Should be good to go.
