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:

Prefix Command Name Constant (Space) Parameter(s) Suffix
# Command Parameter [CR]

Feedback format:

Prefix Device ID Constant Command Name Parameter(s) Suffix
~ nn @ Command Parameter [CR][LF]

Command Structure Rules:

The command framing varies according to how you interface with the VP-427UHD. The following figure displays how the # command is framed using terminal communication software (such as Hercules):

Hercules SETUP Utility Screenshot Description

A screenshot of the Hercules SETUP utility by HW-group.com is displayed. It shows a TCP Client connection to IP address 192.168.110.54 on port 5000, with a status indicating "Connected" and "#~010 OK". The utility includes sections for TEA authorization, PortStore test, and received/sent data logs. The bottom part shows options for sending data via HEX or Send buttons.
