RECOGNITION CHARACTER AND START AND STOP CHARACTERS
The meter recognizes an asterisk (
*
) as the command recognition character. In the counter,
another command recognition character may be chosen to make the meter compatible with an
existing system. The meter will still respond to an asterisk. For all meters, in continuous
mode, a device ,such as a printer, may require a start and stop bit to recognize the data string
being sent. Normally there is no start bit and the stop bit is a carriage return
Counter is in a normal operating mode (not Remote Display), SER 3, XDXXX can be set for
