The Draper LVC-IV Low-Voltage Control Module is a versatile device designed to manage projection screens and other equipment through various control methods. It integrates multiple communication and control interfaces, making it suitable for a wide range of installations, from simple remote control setups to complex integrated control systems.
The LVC-IV module serves as a central control unit for projection screens, allowing operation via infrared (IR) remote, radio frequency (RF) remote, low-voltage wall switches, and serial communication (RS232/RS485). It also features a DC low-voltage trigger input for integration with projectors. The module provides a 230V/50Hz power supply to the screen motor and includes a user-serviceable 3.15 Amp fuse for protection. It can also act as a single-pole, double-throw dry closure for controlling other equipment.
The LVC-IV module offers multiple ways to control a projection screen:
The module includes an IR receiver jack. An optional IR Eye (Part#: 121228) can be plugged into this input. The IR remote control transmitter (Part#: 121227) has a range of 26 feet (7.9 meters) and does not require "learning" by the LVC-IV; simply point and operate. The maximum IR Eye cable length is 42 inches (1 meter).
A built-in RF receiver allows control via an RF remote (Part#: 121226), which has an operating range of 250 feet (76 meters) in open distance. RF signals degrade significantly when penetrating walls (distance falls off by 50% per wall). The RF antenna can be threaded out of a knockout for better reception if signal strength issues occur.

Important RF Notes:
The module features a 3-screw terminal block for connecting a low-voltage wall switch (Part#: 121225) or a low-voltage wall switch with a locking cover (Part#: 121232). This allows for simple, hardwired control of the screen.
The LVC-IV supports "dry" contact closure for control, making it compatible with various third-party control systems. This includes power supply key switches (KS-1, Part#: 121017) and 3-position momentary key switches (SP-KSM, Part#: 121022).
A built-in connection allows for sending a DC trigger (4-28 VDC) from a projector to the projection screen. When the projector is "ON," its low-voltage output triggers the LVC-IV to deploy the screen. When the projector is "OFF," the low-voltage is removed, and the screen retracts.
Two RJ25 ports are provided for RS232/RS485 serial communication, enabling integration with advanced control systems. The ports are identical and use an electrically straight data cable. Command Strings:

Detailed programming instructions and group control information are available on the DraperPro website (registration required).
RJ25 Pinout:The LVC-IV module includes a user-serviceable 3.15 Amp fuse. This allows for easy replacement in case of an overcurrent event, ensuring continued operation of the device. Access to the fuse and other connections is facilitated by the module's design. For any installation or servicing difficulties, users are advised to contact their dealer or Draper, Inc. directly.
