Managing the display using RS‑232

You can connect an RS-232 cable from a computer’s serial output to the display’s RS‑232 in connector to remotely select video inputs, turn the display on or off, and get information about the display’s current settings, such as volume and power state.

Use only a standard RS-232 cable. Do not use a null modem cable. Null modem cables typically have ends of the same type.
