LAN/RS-232 Command Reference
The VR-400UHD support two types of remote-interface communication: LAN and RS-232.
Using the LAN port or RS-232 connector to send specic commands to the VR-400UHD from a controlling device lets you operate the VR-400UHD
remotely.
LAN Interface
This uses the LAN port on the VR-400UHD.
You use Telnet to operate the VR-400UHD remotely over a LAN (TCP/IP
protocol).

(Crossover connection)
* The connections between 4 and 6 and between 7 and 8 are inside the
VR-400UHD.
Command Format
Commands are common to the LAN and the RS-232 interface.
Transmitted commands (control device Óthis unit)
Transmit specic commands from the control device to this unit.
Command Format
ver
Obtains the model name and version information.
ver lf
set
Sets a parameter.
set , Category , ID , Sub-ID , Value lf
get
Obtains the current parameter value.
get , Category , ID , Sub-ID lf
When this unit correctly receives a command, it returns
set,[category],[ID],[sub-ID],[value][lf].
* “lf” is the ASCII code “0aH”, and is a control code that indicates the
end of the command. H indicates a hexadecimal value.
ack response (this unit Ócontrol device)
When this unit correctly receives a command, it returns ack.
The ack response commands are described in
“List of Commands”(p. 3).
Error response (this unit Ócontrol device)
When this unit could not correctly receive a command, it returns an
error.
err , Transmitted command lf

LAN/RS-232 Command Reference
List of Commands
* When sending a sequence of commands to the unit from a controller, after each one, be sure to verify that an “ack” response is returned before
sending the next command.
* The network and password settings must be congured beforehand. When connecting, enter the password you already set.
