Figure (2-5).

Signal of scoreboard is current loop or RS232 signal and it is output serially in binary code with

baud rate of 600. Each frame has 11 bits, i.e. one start bit (0), 8 data bits (lower bits in front), one mark

bit and one stop bit (1).

3. The indicator sends out a group of data every 100ms with 3 frames of data contained. See the

meaning in Figure (2-6).
