The emulator communicates via a virtual COM port. Download and install a high-quality USB-to-RS-232/RS-485 driver (FTDI chipset is most reliable). Do not use Prolific chips with Otis controllers—they cause parity errors.

After installation, open Device Manager → Ports (COM & LPT) . Note your COM port number (e.g., COM3). Set the baud rate to 9600, 8, N, 1 (default for most Otis service modes).
