Mconfig PC software can also be used to setup the VRU Pro offline (away from the panel), then download later.

Mconfig must be installed on the PC used for the file transfers. Access the license agreement and installation from the link below. http://www.fwmurphy.com/software/license

After reading this, click on the link shown at the bottom of that page.

1.7 Most PC’s are not equipped with RS-485 ports, therefore a USB to RS-485 adapter is needed to communicate to the VRU Pro over RS-485. A PC Interface Kit, which includes this adapter, accessory is available for purchase (part #53702325).

1.7.1 It may be necessary, if USB drivers for Murphy controllers are not already installed, to install the USB

Driver setup.exe software. Note: if you have already installed Centurion USB drivers in the past, this step is not required.
