^A ^D COMMAND
X 159 Brownout Reporting:
A brownout condition is a sag or drop in the supply voltage that dips below
16.4Vdc but does not continue to sag and perhaps goes back to the 24Vdc
supply voltage. The printer will attempt to update its configuration and
counters in this condition. Proper power sources should not normally have
situations were Brownouts are a frequent occurrence. The printer provides the
ability to monitor these types of conditions using the D159 command. The
D159 command provides a volatile or running total of the brownouts and a
non-volatile count that is saved.
0 After a power up, reports the “running” total of detected Brownouts.
1 Clears the “running” total or volatile brownout count
5 Reports the non-volatile brownout count stored in memory
255 Clears the non-volatile brownout count stored in memory
163 Sensor Status Byte: This command is used to report the real time sensor
status of all the printer sensors. When the ^D163 command is issued, the
printer returns a byte status that is defined below.
