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

User-Defined
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.
12
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.

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.

when using pair-connection. But please make sure that the tDS-700 has the same setting
as local serial devices.
2. The pair-connection can be created by using same or different tDS-700 models.
The pair-connection is working as port-to-port.

Note: When connecting several tDS-700 (RS-485 master) in RS-485 network, you
should remove the pull-high/low resister in most of the tDS-700 modules, and make
sure there is only one master in the RS-485 network.

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.
