Serial Command API
The Vaddio serial command API is a high-level, text-based command line interface to allow an external
device such as AMX or Crestron to control the OneLINK device. The serial command API can be
accessed via Telnet. Windows provides a built-in Telnet client; PuTTY can also be used.
Telnet connections use port 23.
Note
At the start of the session, you must log in using the admin account.
Note
By default, Telnet access is disabled in all firmware releases issued after December 2019. Enable it on
the Security page of the web interface.
Usage notes:
n
The > character is the command prompt.

Using a question mark as a command or command
parameter will bring up a list of available commands,
subcommands, or command parameters. For example,
? returns all top-level commands; system ? returns the
valid subcommands for the system command; and
system reboot ? returns the parameter available for the
system reboot command.
n
CTRL-5 clears the current serial buffer on the device.
Typographical conventions:

Note
The commands in this manual refer to the OneLINK device. To control the connected camera, open a
Telnet session to the camera's IP address and use the camera's Telnet commands, or connect a camera
controller to the OneLINK device's RS-232 port and use the camera's VISCA-compatible RS-232 serial
control API.
