TRY OTHER COMMANDS
Experiment with other commands to become familiar with the command structures. A short overview of each command
with input and response examples is shown in Section 3 Commands Quick Reference. See Section 5Commands
for complete command descriptions. Until an
SP=ALL
command is executed, no changes will be stored in the
EEPROM. Cycle the power or send an
IN=RESET
command to revert to previous EEPROM settings.
