  • Page 6 *Notice: When you finished the TRP-C29U USB to serial driver install, the O.S will detect dual serial ports. For TRP-C29U there only one set of serial port can be use and the other one set of serial port is non-function 1.
  • Page 7 3-1-1.TRP-C29U Device Installation & Detection: Connect TRP-C29U to the USB Host controller of the PC using a USB cable. The first time you plug-in the cable into the USB port, Windows will start installing the device driver software. You can see the installation status at the pop-up message of system tray.
  • Page 8 will find “MosChip High-Speed USB Serial Port (ComX)” under the category Ports (COM & LPT). Here ‘X’ in ‘ComX’ represents the serial port number. You can see the same in the figure below. 3-2 .Install XP driver Find MSSetup.exe and MSUninst.exe which in the folders for Win XP/2K and Win98/ME operation system.
  • Page 9 Use “MSSetup.exe” utility to install the driver. Double click on the utility to start the installation process. Press “Install” button to install the drivers for High-Speed USB Multi serial Device. During the installation process, a warning message will popup informing the user that the software being used has not passed the Windows Logo testing.
  • Page 10 The utility will display a message stating “Installation completed”. Use “Exit” button to complete the driver installation. Connect TRP-C29U to the USB Host controller of the PC by using a USB cable. The first time you plug the adapter into the USB port, Windows will bring up the "Found New Hardware Wizard"...
  • Page 11 As specified in earlier section, a warning message will popup informing the user that the software being used has not passed the Windows Logo testing. You can ignore the warning message by clicking on the option “Continue Anyway”.
  • Page 12 The following window conveys that the OS had finished the software installation for “High-Speed USB Multi Serial Compound Device”. Click on “Finish” to complete found new hardware wizard.
  • Page 13 Follow the same steps as explained for “High-Speed USB Multi Serial Compound Device” for the second port installation . Select the option “Install the software automatically”…… “Continue Anyway”⋯⋯...
  • Page 14 The following wizard indicates that the OS has completed installing the software for the first serial port. Continue the same process for installing the rest of the serial ports.
  • Page 15 TRP-C29U device detection can be confirmed by checking the Device manager. Check for “High- Speed USB Multi Serial Compound Device” under Universal Serial Bus Controllers and “High- Speed USB Serial Port (Com X)” under the category Ports (COM & LPT) Now the TRP-C29U Device is ready to use.
  • Page 16 “Remove” option. This will remove the MCSTRP-C29U device driver from the PC. The TRP-C29U device driver can be un-loaded through “Device Manager” as well. Go to Device Manager, Select High-Speed USB Multi Serial Compound Device from the Universal serial Bus...
  • Page 17 The OS will prompt the user whether to uninstall the device from the system. Click on “OK” to uninstall or “Cancel” to terminate the un-installation. The Win2K software Installation, Detection and Un-Installation procedures are same as Win XP OS process. The only difference being, there is no need of user intervention during the detection of MCSTRP-C29U.

  • Page 18: System Configuration Switch

    4. System Configuration Switch The TRP-C29U support the Modbus RTU and ASCII communication protocol, It has a two pins external dip-switch that allow user to select protocol between Modbus/RTU and ASCII. The dip- switch also provides “back to default” function when user forget the configuring information stored in EEPROM such as ID (RS-485 Module address), baud rate and data format.

  • Page 19: Function Description

    5. Function description Power on mode: When power fail, system reset or host watchdog timeout will cause the module reboot then into power on mode, the module’s digital output value will return to the before setting. And module can accept the host’s command to change the digital output value. Dual Watchdog: Module self watchdog: The module’s watchdog is a hardware reset circuit while working in harsh or noisy environment, the module may be down by the external, The circuit may let the module to work continues and never halt.
