6.0 Streaming with Ethernet
When using a Lantronix TCP/IP module in Rice Lake indicators which are capable of streaming, stream data can
be sent to a 920i as a serial scale using a corporate Ethernet backbone. This is referred to as serial tunneling. This
section provides a brief overview of how to use serial tunneling. For more extensive information, refer to the
following link:
• http://ts.lantronix.com/tutorials/serial-tunnel/Serial_Tunneling.html
Make sure you consult with your network administrator prior to setting up any streaming functionality.
6.1 Serial Tunneling
The principle of tunneling is to set up the source scale (in this example, a 720i is used) to stream a LFT Condec
format to a receiving unit (920i). These units should be set up and calibrated using RS-232. Data will be sent
from the 720i, so it is noted as the sender. Data is received by the 920i, so it is noted as the listener.
1. If not already installed, install an Ethernet TCP/IP card inside each unit. Refer to Section 2.0.
2. Using DeviceInstaller, set the connected mode of the sender to 05 and of the listener to 30.
The sender will initiate a connection immediately upon going to weigh mode. This will be an autostart
mode of the Ethernet card. The listener then is set to open a connection with no other contingencies upon
detecting a packet directed to its local port.
3. Using Lantronix Device Installer, set the local port of the listener to 3032 and the remote port of the
sender to 3032.
4. Find the listener’s remote IP address and enter it in the sender using DeviceInstaller.
In the following screen captures, IP address 128.1.1.122 was the sender and IP address 128.1.1.123 was
the listener.
