2 ES51978 based multimeter, serial communication
3 -------------------------------------------------------------------------------
5 This is a set of example captures of the serial (UART) communication and
6 its timings on an optical RS232 cable for the ISO-TECH IDM103N digital
7 multimeter based on the Cyrustek ES51978 chip.
9 The UART parameters are 2400 baud, with 7e1 settings.
