2 Quick Start Guide
1. Turn gateway's "mode" DIP switch to "ON" and "function" DIP switch to "OFF"
2. Use crossed network cable to connect the gateway's Ethernet port (RJ45 interface) with that of computer;
3. Power on the gateway, now the IP address of the gateway is fixed: 192.168.0.10 and it is configurable.
1. Open the SST-HE-CFG software installed on your computer;
2. Click "Fieldbus", in the "Mode" item on the right, choose Modbus TCP;
3. Click "Serial setting" in "config" menu, pop up the "Select the serial port" dialog box;
The following example introduces the use of the Gateway.

4． Click "OK"; Select the gateway and Sign in the popup "Search Equipment" dialog box;
5． Select the "Fieldbus" in the tree view on the left, configure as below in the right interface;
6． Click the channel in the tree view on the left, the table appearing on the right is configured as below:

Note: In the HART protocol, it specifies that the device with slave address 0 works under single point mode, it
allows digital communication and analog communication exist at the same time. The device with slave address
0~15 works under the multipoint mode, the analog output of the device is the minimum value (4mA) and it only
allows digital communication. The protocol also specifies that the default factory address is No.0.
7． Right click the channel, select "Add Node" in the popup menu as below:
8. Right click: "Node(0)", select "Add Command" in the popup menu, add Command ID1 in the popup dialog
box (double click "Command ID1" or select "Command ID1" and click "»"), click OK to return.

9. Click "Command ID1", the configuration table on the right is configured as below:
10． Click the icon , in the pop-up dialog box, select the Ethernet port with which gateway is connected to
the computer, and then click Download:

2.2 Function Demo
The HART interface of the gateway GT200-HT-MT connects with a 2-wire pressure transmitter with slave
address 0. The Ethernet port is connected to the PC through network cable. The configured Modbus POLL
software in PC can simulate to work as a Modbus TCP master, and then you can see the main variable value of the
pressure transmitter in data exchange window:

GT200-HT-MT can choose using the internal sampling resistor or external sampling resistor to get the HART
signal. The specification of the internal resistor is 270Ω, 2W. When the power of the sampling resistor is more
than 2W, you must use an external resistor.
