USB-LT02_B User’s Manual 2-2 Installation Process To install the USB-LT02_B 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_B board. - Page 8 USB-LT02_B 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.

USB-LT02_B User’s Manual 3-2 Board Description USB-LT02_B is an I/O board that allows developers who do not know USB at all to simply control external devices by using the provided API. External I/O connection can be easily connected using screw terminals, and a test point is provided on a separate universal board to test simple circuits on its own universal board. -

USB-LT02_B User’s Manual [Table 2. Board ID setting Table] Board ID 3-2-3 D1 LED When USB2.0 Port of PC and USB-LT02_B are connected, USB Power(+5V) is supplied to USB-LT02_B and this LED is turned on. 3-2-4 D2 LED Lights up when all input/output terminals of the USB-LT-2_B board are set as output. Used in sample programs. - Page 13 USB-LT02_B User’s Manual 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 14: Output Terminal
USB-LT02_B User’s Manual 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.) [Table 4. Input Terminal Operation] USB-LT02_B Operation 3-2-8 Output Terminal... - Page 15 USB-LT02_B User’s Manual The circuit between the common terminal and the output terminal is shown in [Figure 3-8]. [Figure 3-8. Photo MOS Relay Output Circuit] For example, MICOM gives a Logic Low signal (GND) to Port4.0 to make P4C1 and P40 conduct.

Page 18: Sample Program
USB-LT02_B User’s Manual 4. Sample Program A sample program is provided along with USB-LT02_B for easy use of USB-LT02_B. Since the USB HID Device uses the operating system's own driver, there is no need to install a separate driver program. The provided sample program is a program that can check the operation of each terminal simply by judging the presence or absence of a board abnormality, setting each terminal as an input or output. - Page 19 USB-LT02_B User’s Manual ③ Select Device When using more than one USB-LT02_B, select the ID of the USB-LT02_B board to check the status or change the setting in the sample program. Device 0 to Device 3 are possible. For example, if you want to select USB-LT02_B with board ID 2, you can select'Device 2'from the Combo Box list as shown in [Figure 4-2] below.
- Page 20 USB-LT02_B User’s Manual [Figure 4-4. Matching of Port Configure value and input/output terminals] The table below matches the output terminal with the Port Configure value, taking the output as an example for understanding. [Table 7. Example of Port Configure Value and I/O Terminal Matching] For the lighting and blinking status of LED lamps, refer to'⑨...
- Page 21 USB-LT02_B User’s Manual [Figure 4-5. Port Configure value when clicking All Input button] However, since USB-LT02_B uses only Port6, Port7 and 1 as input, the input setting of Port4 and Port5 is meaningless. Also, the values displayed in the Port Configure window are only valid for P4 and P5.
- Page 22 USB-LT02_B User’s Manual [Figure 4-7. LED lamp turns on when ON button is clicked] [Figure 4-8. LED lamp blinks when OFF button is clicked] For example, if you click ON button 0 of Port4, P4C1 Port and P40 Port are connected to each other, and if you click OFF button, P4C1 Port and P40 Port are in Open state with the connection turned off.
