LAN Interface Specific Commands and Queries
As indicated before, all commands available for USB or RS232 remote control are supported
over the LAN option interface as well. However, there are additional commands that allow
LAN settings to be changed or queried over the LAN interface. These commands are valid
only for power sources that have the LAN option and are detailed in the following
paragraphs.
Command

Communication Considerations
Consider the following protocols and conventions when using the LAN interface for remote
control of the power source.
•
All of the above commands (excluding the query commands) will respond with the
06 hex (6 decimal) Acknowledge (ACK) ASCII control code if the transfer was
recognized by the instrument.
•
If there was an error with the command string, the instrument will respond with 15
hex (21 decimal), the Not Acknowledge (NAK) ASCII control code.
•
However, the presence of this response does not mean that the instrument (in the
case of these commands only) completed the command. These commands require a
restarting of the hardware that controls the Ethernet Protocols. Because of this, the
user must wait before the Ethernet Card will respond to another command. See the
table below for the approximate wait times necessary after one of the commands in
the table is sent. In addition, the current socket connection between the user’s
terminal and the Ethernet Card is no longer valid, and the user will need to close
their current connection and establish a new one.
