The M1XSP is a "3 in 1" product. As a lighting interface, it adapts the M1 Control to many brands of Lighting control products which use “serial" communications. i.e.,OnQ-ALC, PCS-UPB, EDT, CENTRALITE, VANTAGE, etc.

As a thermostat interface, it adapts the M1 Control to HVAC Communicating Thermostats from companies such as:RCS, APRILAIRE, and HAI. As a serial port expander, it expands the RS-232 communication ports of the M1 for multiple connections to most any type of equipment that communicates using serial ASCII commands. i.e., Personal Computers and many types of equipment which feature an RS-232 communications connection.

Jumpers on the M1XSP select the appropriate application, connection, and protocol.

Best of all, the M1XSP operates from the 4-wire (RS-485) M1 Keypad data bus, allowing RS-232 ports to be located long distances from the control. The M1G (Gold) and M1EZ8 Cross Platform Controls support up to 7 M1XSPs while the M1 (Std) supports 1 M1XSP.

The communications baud rate is adjustable from 300 to 38,400 baud.

The unit comes complete with cable and a black surface mountable housing.
