 ===== Introduction ===== ===== Introduction =====
-{{ :​microsetii.png?​120|Alerton Microset II}}The Microset<​sup>​TM</​sup>​ II is a wall-mounted sensor for BACtalk<​sup>​®</​sup>​ VLCs((The Microset II is not compatible with the Alerton TUX product line)). Depending on the VLC version, the Microset II may be ingterchangeable with previous version BACalk Microsets. See "​Compatiblity with Earlier Version VLCs" on p. 8 for details. The Microset II has a backlit liquid crystal ldisplay (LCD) and intuitive button operation. It connects to a VLC using three low-voltage wires. The Microset II exchanges data and receives commands from a VLC using a range of AV and BV data points in the VLC that are reserved for Microset operation. These data points are available from the VLC as BACnet objects. +Just for playing around.
