tDS-734 (tGW-734) : RS-485 x1, RS-232 x2 (3-wire)
UDP Search
Use "eSearch Utility“ or “VxComm Utility”, you can find the module quickly and configure the proper network settings.

Initial No Yes Factory
Run Yes No User-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.

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.
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.

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.

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.

Note:
1. The tGW-700 act as Modbus/TCP to Modbus RTU/ASCII converter. The client program must use Modbus/TCP protocol.
2. The Modbus RTU or ASCII protocol, baud rate and data format used are depending on the serial devices, and are setting via web configuration.
