    Chapter 1 About Terminal Commands Configuration of This Manual This is the terminal command instruction manual for the VA-1842 series. It describes the setting procedures, precautions, and other matters using the configuration shown below. Read this manual carefully to ensure correct operation and setting.

  • Page 9: Chapter 1 About Terminal Commands

    This manual describes the sending and receiving of the commands and data required for operating the HDMI protocol analyzer (hereinafter referred to as the VA-1842) from an external computer (such as a PC). The commands and data are sent and received via the serial input/output port LAN or USB peripheral.
