Our Price : $302.00

Product Code: H4-MR232G


The MR232 Network Controller provides the communication interface between a Miro wireless lighting control system and other RS232 compatible building controls. It acts as a command and control station using an ASCII communication protocol. With it, both humans and automation systems can control virtually any Miro device on the wireless network. The MR232 provides the ability to offer interconnectivity with automation system and building control integration providers.

The MR232 interfaces to an automation system through an industry standard RS232 port. In a typical installation the interface is bound to a specific installation or house. This binding provides direct access of the house presets as well as the 127 rooms and the 4095 possible groups on the network. To query the wireless system and log the control points (devices), connect the MR232 to a PC running a generic terminal emulator such as Windows Hyper-TerminalTM at 38.4Kbd. From this interface, the user can build an installation list and use it to create a spreadsheet of all the possible control points (devices) available on the network. These control points can then be programmed into the automation systems and provide a seamless control environment between the two systems.

Top Dog Wireless Communication:

Miro wireless devices use radio signals to communicate with each other to control lighting and other types of electric loads in selected areas. These wireless devices use the 900MHz band for high-speed control communication. Using the "frequency-agile" Top Dog technology, these wireless devices avoid interference with other 900MHz devices, such as cordless phones and baby monitors.
