LAN/RS-232 Command Reference

The VR-6HD support two types of remote-interface communication: LAN and RS-232.
Using the LAN CONTROL port or RS-232 connector to send specific commands to the VR-6HD from a controlling device lets you operate the VR-6HD remotely.

LAN Interface

This uses the LAN CONTROL port on the VR-6HD.
You use Telnet to operate the VR-6HD remotely over a LAN (TCP/IP
protocol).

shown below, and press the [VALUE] knob.
Menu item Explanation
Selects how settings are made for the IP
address, subnet mask, and default gateway.
USING DHCP:
The IP address and other information needed
CONFIGURE
for connecting to the network is obtained
automatically from the DHCP server of the LAN.
MANUALLY:
The IP address, subnet mask, and default
gateway are specified manually.
IP ADDRESS
Shows the IP address. (*1)
SUBNET MASK
Shows the subnet mask. (*1)
DEFAULT GATEWAY
Shows the default gateway. (*1)
(*1) When "CONFIGURE" is set to "MANUALLY", set these respectively
according to the network.
2 .
Use the [VALUE] knob to change the value of the setting.
3 .
Use the [VALUE] knob to select "NETWORK PASSWORD",
and press the [VALUE] knob.
4 .
Set a network password (four characters).
Input the password that's set here when connecting a computer or other
device on the same network to access the VR-6HD.

VR-6HD.

Command Format

Commands are formatted using the configuration shown below.
Commands are all in ASCII code.
* Commands are common to the LAN and the RS-232 interface.
stx Command code
ASCII code "02H" is a control code indicating the start of
stx
a command. "H" indicates that it is a hexadecimal value.
This specifies the command type (three single-byte
Command code
alphanumeric characters).
This is appended to a command that requires one or
more parameter. The command and the parameter
Parameter portion are separated by a " : " (colon). When there are
multiple parameters, they are each separated by " , "
(comma) characters.
This is the code that this unit recognizes as the end of
;
a command.
* The codes of stx (02H), ack (06H), xon (11H), and xoff (13H) are the control
codes.
