UDP Search

• Use "eSearch Utility or VxComm Utility, you
  can find the module quickly and configure the
  proper network settings.

11
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.

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
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.

  module with no protocol convert. This allows most
  of the serial protocols can be used with the
  virtual COM.

• Note
• PLC 1 and PLC 2 can use different baud rate and
  different data format at the same time when using
  pair-connection. But please make sure that the
  tDS-700 has the same setting as local serial
  devices.
• The pair-connection can be created by using same
  or different tDS-700 models.The pair-connection
  is working as port-to-port.

pull-high/low resister in most of the tDS-700
modules, and make sure there is only one master
in the RS-485 network.
