Synappx Go FOR ADMIN

Automatic Input Switch

Step 1: Configure Interactive Whiteboards

There are two options for configuring auto-input switching on supported Sharp displays. Telnet over LAN is recommended because it does not require a physical cable. If your display does not support telnet, use RS-232C, which is available across all display models.

General Display Configuration Notes

  • The Go display agent and display must be on a network where they can communicate directly.
  • In power save mode, the monitor may not wake up as LAN is turned off (default setting).
  • For models PN-L651H and PNL-C751H, the input switch command is not accepted for up to a minute after power-on. The switching command will not work on initial power-on because the switch command is sent after power-on.
  • It is not recommended to use the Crestron® control interface and Go auto-input switch at the same time. Since both options can change inputs dynamically, the results may not be as expected.
  • On some models, Consumer Electronics Control (CEC) can be enabled for automatic switching when a device is connected to the display. This may cause unexpected results as the display will switch away from the original view. In that case, disable the CEC feature for auto-switch use.

If you encounter display configuration issues, go to Troubleshooting Tips and/or check with your display integrator for configuration support.

Telnet over LAN

Check your display operation manual for Controlling the Monitor with a Computer (LAN). On most models, the settings are accessible from the menu on the remote or application screen.

  1. Ensure the display is configured with a static IP Address.
  2. Go to Settings > Communication or Setup Ethernet (LAN) (applicable to most models). Most models require either LAN or RS-232C as a selection in the display menu.
  3. Ensure the telnet server is set to On and create a user and password (this can be different from the admin user on the board).
  4. For displays supporting Application mode: Go to the display board and select Application Input on the screen.
  5. Open the Settings/Setup menu.
  6. Configure settings to use a Telnet server:
    • Telnet Server ............................... When using Telnet Server function, set to ON
    • Username ........................Set an account name when connecting to this display
    • Password................................... Set a password when connecting to this display

Make note of the display IP address, port number (default is 10008), username and password (if set), and the input port to be configured for use with the display PC. This information is necessary when completing the display information setup on the Synappx Go Admin Portal.


  1. Read the display operation manual for Controlling the Monitor with a Computer (RS-232C).

  2. Ensure all RS-232 cables are connected securely to the display board, ideally using the provided screws. [View Image]
  3. In Windows®, go to Device Manager to confirm the port that the agent PC is using to communicate with the display (e.g. COM3, COM5). [View Image]

  4. On some models, the RS-232C settings are accessible from the menu on the remote or display application screen. Go to Settings > Communication or Setup Ethernet (LAN). Switch to RS-232C.
  5. For displays supporting Application mode, select the Application input. Open the Settings/Setup menu on the display.
  6. Note the baud rate on your display. Some displays have a fixed baud rate (e.g. 9600) while others allow it to be configured. The settings in the Admin Portal must match the display settings for com port and baud rate.
