Communications and Firmware Upgrade Instructions
071377001 April 2022 *P071377001*1
Overview
This document describes how to use the Model 2306-LAN Battery/Charger Simulator and connect to a local
area network (LAN) and how to upgrade the firmware.
The Model 2306-LAN is a TCP/IP protocol supported instrument. There is one LAN port that supports full
connectivity on a 10 Mbps or 100 Mbps network. The 2306-LAN automatically detects the network speed.
Figure 1: Model 2306-LAN connection location
Contact your network administrator to confirm your specific network requirements before setting up a
LAN connection.
If you have problems setting up the LAN, refer to LAN troubleshooting (on page 14).
Set up LAN communication on the instrument
The following information describes how to set up manual or automatic LAN communications.
See the Model 2302/2302-PJ/2306/2306-PJ/23-6-VS Battery/Charger Simulator Quick Results Guide
(document number: 2306-903-01) for other setup information and the Model 2302/2302-PJ/2306/2306-PJ/23-6-

LAN cable connection
Connect a LAN cable from your computer to the LAN port on the rear panel of the 2306-LAN.
Figure 2: Model 2306-LAN cable connection
Each device on a LAN (corporate or private) requires a unique IP address. Contact your corporate information
technology (IT) department for details about obtaining an IP address before you connect the 2306-LAN to a
corporate or private network.
Contact your corporate IT department for permission before you connect the 2306-LAN to a
corporate network.
When the 2306-LAN is shipped, the IP configuration is set to manual and is set to the following values:
Instrument IP address: 192.168.0.2
Gateway: 192.168.0.1
Subnet mask: 255.255.255.0
These values persist through a power cycle unless they are changed or the LAN RESET button is selected. If
the LAN RESET button is selected, the TCP/IP mode is set to manual. For more detail on the LAN RESET
button, refer to the Check communication settings (on page 3).
Configure your computer and the IP address of the instrument on the same network, as indicated in the
following graphic.

LAN configuration through a computer
You will need to download the 2306-LAN Configuration Tool from the Product Support and Downloads web
page. This tool provides the interface needed to set up the 2306-LAN IP address, subnet mask, gateway, and
port from a computer. Once the executable file for the configuration tool has been downloaded to your
computer, the following information describes how to install and use the tool.
For firmware upgrade information, go to Firmware upgrade instructions (on page 12).
Do not use this configuration procedure for the Series 2300 models 2302, 2303, 2306, or 2308
instruments.
To use the LAN Configuration Tool:
1. Double-click the 2306-LAN Configuration Tool.exe file.
2. Select Scan Devices.

AUTO-MDIX
The Model 2306-LAN does not support automatic MDIX (medium dependent interface crossover)
feature. However, with an AUTO-MDIX network card, it is possible. We recommend using straight-
through cables to connect the 2306-LAN to switches or routers, and crossover cables to connect the
2306-LAN workstations or servers. Also, if the Model 2306-LAN instrument is connected to a
personal computer, router, ethernet switch, or other devices that contain an enabled AUTO-MDIX
network card, you can use either type of cable.
LAN interface protocols
You can use one of following LAN protocols to communicate with the 2306-LAN instrument.
Port number
Protocol
1024
VXI-11
5025
Raw socket
You can only use one remote interface at a time. Although multiple ethernet connections to the
instrument can be opened, only one can be used to control the instrument at a time.
VXI-11: Similar to a GPIB cable and supports message boundaries and service requests (SRQs). A VXI-11
driver or VISA software is required.
Raw socket: Basic ethernet connection that communicates similarly to RS-232 without explicit message
boundaries. The instrument always terminates messages with a line feed. However, binary data may include
bytes that resemble line feed characters and it may be difficult to distinguish between data and line feed
characters.
Programming C# examples
See the following VXI-11 protocol C# example (on page 8) and the Raw socket protocol C# example (on page
9) for detail.

VXI-11 protocol C# example
When you use the VXI-11 protocol to communicate with a 2306-LAN instrument, use the C# (C-sharp)
programming language using the following example (in the order indicated) to program your instrument.
1. Open resource.
2. Configure resource.
3. Send a command or READ data.

Raw socket protocol C# example
When you use the VXI-11 protocol to communicate with a 2306-LAN instrument, use the C# (C-sharp)
programming language using the following example (in the order indicated) to program your instrument.
1. Set the IP address.
2. Set the port.
3. Connect to the instrument.
4. Send a command or READ data.

// set instrument TCP port:5025
ipe = new IPEndPoint(ip, 5025);
clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp);
//Connect to instrument through LAN
clientSocket.Connect(ipe);
//send message
string idnCommand = ":SOUR:VOLT 5;:OUTP ON;:READ?";
//send command
set 5v, output on, read volt value
//Command encodes to byte array
byte[] sendBytes = Encoding.ASCII.GetBytes(idnCommand);
//send command
clientSocket.Send(sendBytes);
C//windows console output
Console.WriteLine("Send: " + idnCommand);
//receive message
string recStr = "";
//define receiving array . length 4096 bytes
byte[] recBytes = new byte[4096];
//receive command response
int bytes = clientSocket.Receive(recBytes, recBytes.Length, 0);
//encoding to strings
recStr = Encoding.ASCII.GetString(recBytes, 0, bytes);
//console output strings
Console.WriteLine("2306-LAN feedback: " + recStr);
clientSocket.Close();
//pause
Console.Read();

NI-VISA example program
NI-VISA is National Instruments (NITM) implementation of the VISA standard. The Keithley I/O Layer
(KIOL) contains a licensed version of the NI-VISA Runtime Engine that contains only the binary files
(DLLs) that allow the NI-VISA drivers to operate.
If you already have NI software (such as LabVIEWTM or LabWindowsTM) installed, you have a valid
license that can be used with Keithley drivers and application software.
If you do not have NI software installed, you must Install Keithley I/O Layer to install the drivers.
VXI-11 NI-VISA protocol example
In the example program, you can query the model information of the instrument using the *idn? command, as
shown in the following figure.
The VISA resource name must be configured, as shown in the following figure.
