10. UDP Search Use "eSearch Utility“ or “VxComm Utility”, you can find the module quickly and configure the proper network settings.

11. Init Switch ModeFlash ProtectionFirmware UpdateConfiguration InitialNoYesFactory RunYesNoUser-Defined  If there are something wrong in network settings or other settings accidentally, you can make the switch is placed in the “Init mode”. After re-booting, all values can be restored to factory settings.

12. 12 Firmware Update (1/2) Connect the tGW-700 to the same HUB or same sub-network as your PC. (For tDS-700, tGW-700, PETL-7000 and tPET Series) Right-click above the module name and choose the firmware file in “eSearch Utility”. Power-on reboot the module in initial mode to request the update.

13. Firmware Update (2/2) The tGW-700 has a built-in feature of flash protection that prohibits modification to the firmware in the flash. Before updating the firmware, we have to set “Init Switch” in “Init” state and then power-on reboot the tGW-700 and disable the flash protection. Since the flash becomes writable, we can update the firmware through the Ethernet network 。 The code (in the boot loader) used to update the firmware image is not part of the firmware it-self. Thus, users can update the firmware even the built-in one is broken or does not exist. If the firmware update fails, we just need to rerun the update procedures again.

16. Virtual COM Basis Meter PLC 10/100 M Ethernet RS-485 VCOM6/7 Transparent tDS-725 Command/Data/Modbus/Anything Note: 1. In the virtual COM application, the command or data is being copied between the PC and tDS-700 module with no protocol convert. This allows most of the serial protocols can be used with the virtual COM. Transparent (with no protocol convert) Meter PLC RS-485

The max. COM port number in a PC is up to COM256. 2. The COM port is configured and mapped by using the VxComm Utility.

18. Direct TCP Socket Connection Meter PLC 10/100 M Ethernet RS-485 tDS-725 Send raw data via TCP socket. Raw data Note: 1. The serial ports of the tDS-700 can be also accessed via TCP socket connections. TCP port 10001 = COM1, TCP port 10002 = COM2, TCP port 10003 = COM3. 2. Users have to configure the baud rate and data format via web configuration first, else the serial ports may send garbage data.
