42 | * Note 1: The actual baudrate of the Cyrustek ES519xx chip used in this DMM | |
43 | * is 19230. However, the WCH CH9325 chip (UART to USB/HID) used in (some | |
44 | * versions of) the UNI-T UT-D04 cable doesn't support 19230 baud. It only | |
45 | * supports 19200, and setting an unsupported baudrate will result in the | |
46 | * default of 2400 being used (which will not work with this DMM, of course). | |
