Protocol 3000
Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or
Ethernet ports.
Understanding Protocol 3000
Protocol 3000 commands are a sequence of ASCII letters, structured according to the
following.
• Command format:
• Command parameters – Multiple parameters must be separated by a comma (,). In
addition, multiple parameters can be grouped as a single parameter using brackets ([
and ]).
• Command chain separator character – Multiple commands can be chained in the
same string. Each command is delimited by a pipe character (|).
• Parameters attributes – Parameters may contain multiple attributes. Attributes are
indicated with pointy brackets (<…>) and must be separated by a period (.).
The command framing varies according to how you interface with VM-218DTxr. The following
figure displays how the # command is framed using terminal communication software (such
as Hercules):
