The Draper 121177 MC1 and LS100 Low Voltage Control Board and Internet Protocol Interface Device includes everything needed to to control a screen, lift, or shade via serial commands. The MC1 Low-Voltage Control Module with RS232 provides multiple input control options for screen, lift or shade motors. This simply designed, but powerful control board accepts 2-way serial communication (with or without relay closure), infrared commands via IR receiver, and relay closures found in home integration systems. The LS100 Internet Protocol Interface Device is used to control one 115 volt motor by network communication. Combining the MC1 with the LS100 allows the user to control screen, lift, or shade motors.
