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. 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. As a result, 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socket connection between the user’s terminal and the Ethernet Card is no
longer valid, and the user will need to close their current connection and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. See section 5.7.5. Ethernet Settings Commands and
Companion Queries for a full list of the Ethernet protocol commands.
Ethernet Card Settings Command Wait Times
*Wait times are approximate and can vary based on the user’s network.
Ethernet Interface
The Ethernet interface provides all of the function control of the standard RS-232
interface. Some commands are only exclusive to GPIB control.
Default Settings
The default settings for the Ethernet interface are as follows:
IP Setup: AUTO
IP Address: 010.000.000.000
Gateway IP: 000.000.000.000
Subnet Mask: 255.000.000.000
The source port number for the Ethernet Card in TCP connections is 10001.
Ethernet Card Setup
In order to setup the Ethernet card, the operator will need information from the
local network administrator. Please have your network administrator fill out the
required information on the next page and keep it for your records:
