4 Quick Start Guide
4.1 Connection
1. Make sure the GT200-HT-EI is in the appropriate operating mode that allows configuration. It’s
recommended to set the gateway to configuration mode ( configuration switches Bit 1 OFF and Bit 2 ON)
then the IP of the gateway is fixed at 192.168.0.10.
2. Connect the GT200-HT-EI to the computer by Ethernet cable.
3. Connect the HART instruments and power supply referring to the topology in chapter 2.7.
4. Power on the gateway, run the SST-HI-CFG software and start the configuration.
4.2 Configuration
The following steps give an example. The GT200-HT-EI is connected with a HART instrument which supports
HART protocol V5 in point-to-point mode, configured with HART command 01, 03 and 06.
For more details of the software SST-HI-CFG, please refer to chapter 5.
1. Run the SST-HI-CFG software installed on the computer. Click “Upload” on the toolbar and scan available
gateways in the network. Select the gateway and click “Sign In” to upload the configuration.
Note: Make sure that the GT200-HT-EI and your computer are in the same network segment. If you can’t
discovery any gateways, please test the network connection first, referring to the note How to Use the Ping

Command.
For the first time to use GT200-HT-EI, the uploaded configuration is a default configuration created by SST
Automation. You can change the parameters based on the default configuration or create a new project. The
following steps introduce how to configure for a new project.
2. Select “Ethernet” at left, and set the Ethernet parameters.
3. Select “HartChannel0” at left and set the HART channel parameters. As shown below, the GT200-HT-EI is
configured as the secondary master and using the point-to-point mode.
4. Add a HART node (chapter 5.2.2.2). In point-to-point mode, the address of HART instrument is fixed at 0.
5. Add HART commands (chapter 5.2.2.3).

6. Configure the commands (chapter 5.2.2.4, 5.2.2.7). According to HART universal command specification,
the command 01 has no request with 12-byte response, the command 03 has no request with 24-byte
response, and the command 06 has 1-byte request with 1-byte response. The request data of GT200-HT-EI
includes extra 2-byte status, so the receiving data length is 2-byte more than the actual response.
After inputting the sending and receiving data length, click “AutoMap” on the toolbar to automatically map
the data to the EtherNet/IP side (chapter 5.2.4). You can also map the data manually.
The configuration of the HART commands are shown as below:

7. Check the mapping address in Conflict Detection window (chapter 5.2.3). Download the configuration. Click
“Download” on the toolbar, select the gateway you want to download to and click “Sign In”.
Note: The GT200-HT-EI will apply the new configuration after reset. After downloading, the software will
ask to reset the GT200-HT-EI. You can also power off then power on the GT200-HT-EI to reset.
8. Test the communication.

4.3 Test Communication
In this example, the EIPScan Test Tool is used to simulate the EtherNet/IP scanner. The configuration is the same
with that in chapter 4.1.2. The SST-HI-CFG software provides debug and monitor tools (chapter5.2.7, 5.2.8, 5.2.9).
For more EtherNet/IP connection details, refer to chapter 7 and chapter 8.
1. Set the configuration switched to Bit 1 ON and Bit 2 OFF (debug mode). Restart the GT200-HT-EI to apply
the mode switching.
2. Click “Diagnose” on the toolbar and upload the configuration. Check the request and response status in the
diagnose window.
Select a node and double click on a command to check the data. For example, select HART command 03:

3. After confirming the data in diagnose window, click “Memory” on the toolbar and sign in the GT200-HT-EI.
Check the data bytes and mapping address.
The input data in the Memory data window corresponds to the input at EtherNet/IP side. The output data
corresponds to the output at EtherNet/IP side.
Note: The first 4 bytes in the EtherNet/IP input area is the gateway status.
