  1. Examples of Applicationsfor the tDS-700 Dec.22, 2010 P.1

  2. Virtual COM Basis Command/Data/Modbus/Anything Command/Data/Modbus/Anything Transparent (with no protocol convert) VCOM6/7 VCOM6/7 Transparent RS-485 PLC 10/100 M Ethernet RS-485 tDS-725 PLC Note: In the virtual COM application, the command or data is being copied between the PC and tDS-700 module withnoprotocol convert. This allows most of the serial protocols can be used with the virtual COM. The max. COM port number in a PC is up to COM256. The COM port is configured and mapped by using the VxComm Utility. For Modbus/TCP to Modbus RTU/ASCII gateway, please refer tGW-700 models. Meter Meter P.2

  3. Virtual COM Application VxComm Driver VCOM5 VCOM5 VCOM6 VCOM7 VCOM8 … RS-232 RFID Reader tDS-712 VCOM6 10/100 M Ethernet RS-485 PLC tDS-715 VCOM7 RS-485 PLC VCOM8 NS-208PSE Ethernet Switch with PoE Meter Meter Meter tDS-725 RS-485 PLC P.3

  4. Direct TCP Socket Connection Raw data Send raw data via TCP client socket. Transparent (with no protocol convert) Port 10001 (COM1) Port 10002 (COM2) RS-485 PLC 10/100 M Ethernet RS-485 tDS-725 PLC Note: 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. Users have to configure the baud rate and data format via web configuration first, else the serial ports may send garbage data. Meter Meter P.4

  5. Serial Port Pair-connection Basis Virtual RS-485 bus through the pair-connection. Port 1(RS-485) Port 1(RS-485) Serial Port Pair-connection Through the Ethernet PLC 1 uses 115200 bps PLC 2 uses 115200 bps tDS-715 uses 115200 bps tDS-715 uses 115200 bps Note: • PLC 1 and PLC 2 can communicate with each other via the RS-485 port that has pair-connection link through the Ethernet. P.5

  6. Pair-connection with Different Baud Rate Virtual RS-485 bus through the pair-connection. Port 1(RS-485) Port 1(RS-485) Serial Port Pair-connection Through the Ethernet PLC 1 uses 9600 bps PLC 2 uses 115200 bps tDS-725 uses 9600 bps tDS-715 uses 115200 bps 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. P.6

  7. Virtual RS-485 Network (base on pair-connection) Serial Port Pair-connection Through the Ethernet Port 1 Port 1 RS-485 PLC Port 2 tDS-715 tDS-725 Port 1(RS-485) Serial Port Pair-connection Through the Ethernet Port 1 PLC Port 2 Port 2 (RS-485) Port 3 tDS-725 Meter tDS-735 RS-485 Port 1 (RS-485) Serial Port Pair-connection Through the Ethernet Port 2 (RS-485) tDS-725 Meter Note: When connecting several tDS-700 (RS-485 master) in RS-485 network, you should remove the pull-high/low resister on the RS-485 port in most of the tDS-700 modules, andmake sure there is only one master in the RS-485 network.
