5-1
The meter can operate at any rate from 300 to 19,200 in 2:1 steps.
Following are the baud rates used by the meter:
300, 600, 1200, 2400, 4800, 9600, and 19200.
5. Baud Rates
Ten or eleven bits are used for each character: a start bit, 7 bits for the ASCII
character, one parity bit, and either one or two stop bits. If the parity bit is
chosen as “none” (absent), the stop length is automatically set at two bits by
the meter (to keep the minimum character length to ten bits).
Figure 6-1 shows the mark/space sequence.
Figure 6-1. Character Waveform
The rising edge of the start bit of the next character may occur at any time
after the end of the last stop bit.
