Digital View and RS-232/Ethernet

Serial Communication Protocol

RS-232 and Ethernet are standard ways for PC’s to communicate with devices. Digital View was a pioneer in offering support for serial RS-232 for LCD controllers and again with Ethernet control.  Although we have an extensive suite of over 50 commands, some of the most commonly used functions include:

  • Soft Power on/off (standby)  
  • Input source select
  • Backlight Brightness adjustment
  • Other On Screen Display menu functions are  listed in the manual

Other controller commands (depending on model*) that are also accessible via RS-232/Ethernet include:

  • Color adjustment
  • Aspect ratio
  • PIP window selections
  • Text overlay
  • Volume control
  • Fan monitoring
  • Temperature
  • Failover

As a note, for controller models that do not have built-in Ethernet connectivity there is the IP-60 add-on board providing this and support for the full range of commands for the connected LCD controller.

*Please review Digital View’s product manual for controller support of specific serial functions. The manual with full RS-232 functions is available on every product webpage for download.

Answer Back / Echo

The RS-232 system provides the option of an answer back, it will echo the command sent to it so the sender can confirm the command that was sent and that it was received. This function can be disabled.

A benefit to this function is that it can be used to send a command in a series to multiple controller boards (monitors).
