K-Config (Kramer configuration software):
All the examples provided in this section are based on using the
Kramer K-Config software.
You can enter commands directly using terminal communication software (e.g.,
Hercules) by connecting a PC to the serial or Ethernet port on the VSM-4x4A . To
enter CR press the Enter key ( LF is also sent but is ignored by the command
parser).
Commands sent from various non-Kramer controllers (e.g., Crestron) may require
special coding for some characters (such as, /X## ). For more information, refer to
your controller’s documentation.
