Draper Screen Serial Control Utility: Downloads and Configuration

The Draper Screen Serial Control Utility allows installers to configure and send direct commands to motorized screens and projector lifts via RS232 or RS485 serial communication. It bridges the gap between control systems and Draper hardware modules like the ⁠LVC-IV (Low-Voltage Control Module) or specialized interfaces like the ⁠R2D7 RS232 Interface. Core COM Port Configuration

Before sending commands, your computer or control processor must match the exact interface specifications: Baud Rate: 9600 bps Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None Formatting Commands

The utility relies on basic alphanumeric syntax formatted into compact strings to control channels and motor directions:

Header / Prefix: Use an asterisk (*) to announce the command sequence to the data bus.

System Number: Specify the targeting channel (e.g., 1 for channel one or 0 for all systems).

Action Commands: Use lowercase letters for operation strings: o = Open / Down c = Close / Up s = Stop immediately

Terminator: Close every instruction block with a semicolon (;) or a Carriage Return (CR). Physical Wiring Setup

For the serial utility commands to succeed, physical signal infrastructure must be wired cleanly:

Pinout Connections: Establish a standard three-conductor data stream linking RS232 Data FROM, RS232 Data TO, and Signal Ground.

Ethernet Bridging: If managing commands across a local area network, use an ⁠LVC-IP Bridge Kit to cleanly convert incoming IP packets into serial relay signals.

Are you using a specific control module like the LVC-IV or the R2D7 interface, or are you programming a third-party control system like Crestron or Control4? Draper, Inc. Network Serial Communication LVC-IV & LVC-IP Bridge Kit
