DIGITAL OUTPUT
1. Asynchronous RS232 port, 8 bit data, 1 stop bit, no parity control.
2. Transmission rate - 115 k Bod (repetition rate ~ 0.6 kHz).
3. LSB = 0.298μV
4. Additional data (Xdata) - temperature (ADC board), supply voltage, consumption currents, the outputs of built-in temperature sensors. These data (16 bits each) are transmitted in series of 32 sendings according to the status of COUNTER.
