RS RESET COMMAND

Used to reset errors, coulomb count, and energy count. Can

also save settings to EEPROM and restore default settings.

Send hex codes shown.

Rebooting will restore previously saved settings if current

settings are not saved. This will prevent baud rate or address

change errors since you will need to connect with the new

values before you can issue the save to EEPROM command.

0x01

- Reset Coulomb and Energy counters

0x04

- Reset Errors

0x0F

- Save settings to EEPROM

0XAA

- Reset settings to defaults

(command must be sent 3X in a row)

Example: Reset Errors

Send: :1RS04<cr>

Receive: (none)

SA SET ADDRESS

Used to change the SSD address. Send the new address

(1-255) and the SSD will immediately change to it. Connect

with the new address and issue a save settings to EEPROM

command, RS0F, otherwise the old address will be restored on

reboot.

Example: Set SSD address from 1 to 25, then save settings to

EEPROM.

Send: :1SA25<cr>

Receive: (none)

Send: :25RS0F<cr>

Receive: (none)

NOTE: No settings are saved until a save settings to EEPROM command is issued!

Power cycling will restore previous settings. See RESET command :1RS0F<cr>
