# Reconfiguring an RS 232 Device Through the Designer UI

This method should be used before the project is put in runtime mode.

If you have already created and connected to an RS232 device, and then want to deploy the project to a new environment that has another RS232 device with different configuration options, the RS232 device will have a broken link icon beside it.

1. To use the new device, from the Project Explorer, right-click on the RS232 device and select Reconnect.

2. This will launch the Parameter Configuration dialog, which will allow you to reconfigure the settings accordingly (allowing you to retain any previously constructed scripts).
