4. Serial Data Output  
The serial data sent to SDO pin twice every A/D conversion cycle. The data format  
complies with JIS 7Bits transmission code with a baud rate of 19230. The host can use  
RS232 interface to read the data. A single data packet includes a start bit (always 0), 7  
data bits, an odd parity check bit, and a stop bit (always 1). The high and low voltage  
levels correspond to DGND and V- respectively. SDO remains at 1 (high) when it is  
inactive. Hence the start bit (0) could be used as the triggering signal to begin the  
reading process. The following figure shows the data format of a single packet. The  
LSB is sent first and the MSB is sent last.

One data block consists of 11 packets, or 110 bits. The following figure shows the  
format of a data block. The range packet indicates the full scale range of the meter.
