  • Page 7: Installation Process

    2-2 Installation Process To install the USB-LT02 board on the PC, follow the steps below. In the case of USB, since it is a Hot Plug and Plug & Play device, there is no special consideration for installing the USB-LT02 board. Also, since USB-LT02 is connected by HID (Human Interface Device), there is no need to install a dedicated device driver.
  • Page 8 USB-LT02 User‟s Manual (4) Check whether the connection is normally established in the following way. On the My Computer -> Properties -> Device Manager screen, check if 'HID Standard Supplier Defined Device' or 'HID Compliant Device' appears in 'Human Interface Device'. If it appears as shown in [Figure 2-4], the installation has been completed normally.

  • Page 9: Usb-Lt02_B Board Description

    [Figure 3-1. USB-LT02 Layout] If you look at the picture above, in the case of USB-LT02, I/O functions are easy to use, and a simple circuit can be configured on a universal board by itself. A description of each is as follows.

    USB-LT02 User‟s Manual 3-2-5 SW1 Switch Press to reset the board. 3-2-6 Input Terminal [Figure 3-4. Input Terminal] The input terminal is a photo coupler, and the input voltage range is 12V ~ 24V. (For less than 12V, please contact us) It is designed so that there is no power polarity, and one common terminal is used per 4 input terminals.
  • Page 13 USB-LT02 User‟s Manual [Figure 3-5. Photo Coupler Input Circuit] For example, if GND is connected to P1C1 (common terminal) and the voltage level of the signal input to P70 is 12V, the input of USB-LT02_B is ON. (The polarity of the input voltage is irrelevant.)

  • Page 14: Output Terminal

    USB-LT02 User‟s Manual 3-2-7 Output Terminal [Figure 3-6. Output Terminal] The output terminal uses a photo MOS relay, and the output control voltage range is P54, P55, P56, P57 and The maximum P5C2 terminal is 350V, and the continuous current that can flow is 130mA.
  • Page 15 USB-LT02 User‟s Manual The circuit between the common terminal and the output terminal is shown in [Figure 3-7]. [Figure 3-7. Photo MOS Relay Output Circuit] For example, MICOM gives a Logic Low signal (GND) to Port4.0 to make P4C1 and P40 conduct.

  • Page 21 All files specified above are included on the supplied CDROM. A sample program is provided with the USB-LT02 to facilitate the use of the USB-LT02. Since the USB HID Device uses the driver of the operating system itself, there is no need to install a separate driver program.

  • Page 22: Test

    The test is executed using the “sample1.exe” program in the Exe folder of the CDROM on the PC where the USB-LT02 board is installed. The App and App0 folders of the CDROM contain the executable files and source files of sample1 and sample2, so the executable files are used for testing, and the provided sample source files can be modified and used by the user to implement the necessary functions.
