 In this video, we will be covering how to address AUI keypads through Vista Residential Panels. On Vista Residential Panels, such as the 15P, 20P, and 21IP, addresses 1 and 2 are always enabled by default, and each keypad needs a unique address. On new installs of AUI keypads, such as the Tux Wi-Fi, after power-up, you will be prompted to set up the keypad. Make sure that normal operation is the only thing selected, then press OK. Next, you will select your Tuxedo ECP address, then press OK. For existing installs, press Tools, System, CS Setup, then enter in the installer code of the panel. If you have an ECP error displayed, use code 4140 instead. Select ECP address, set your address, then press Apply. That's all for this video. Thanks for watching.
