Support for Multiple Data Interfaces: The DT3 data cable test PCB board supports common data interfaces, including USB, Type-C, Micro-USB, and more. It offers versatility and compatibility with a wide range of data cables. : ELECTRICAL Application: Measuring Set Product size: 50.00x50.00x9.00mm/1.97x1.97x0.35inch Description: DT3 Data Cable Detection Board Quick detection of data line anomalies If all indicator lights are on, the data cable is normal. If one indicator light is not on, it indicates that the data cable is abnormal. Indicator light description: If all four indicator lights are on, the data cable is normal (dual headed type-c data cables require all five indicator lights to be on). If VCC or GND is not lit, it indicates that the data cable charging function is abnormal. D+or D - off indicates abnormal data transmission function. CC is specifically designed for dual type-c data line detection. When testing other data cables, the light does not turn on. Test scope: Type-c to Type-c Type-c to for interface USB to for interface USB to Type-c USB to Mini Interface distribution The operation is simple, the detection is convenient, and the detection efficiency of the data line is improved. Instructions for using the tester: 1. Use a type-c charging cable to plug into the power port to power the product. 2. Insert one end of the data cable to be tested into the corresponding port. 3. Insert the other end of the data cable into the corresponding port. 4. Observe the indicator light.
