CK – Save Command Parameters to Flash
Purpose
Stores present parameters to non-volatile memory.
Format
CK
Recommended Setting
. Use as needed.
Description
CK saves the present user command parameters to non-volatile memory on the CPU
board. The RiverPro/RioPro maintains data stored in the non-volatile memory (user set-
tings) even if power is lost. It does not need a battery. Recall parameters stored in non-
volatile memory with the CR0-command (see
CR – Restore Command Defaults
).
Always use the CK command in the configuration files.
The RiverPro/RioPro ADCP automatically stores the last set of commands used in RAM
(volatile memory). The user can store the configuration into non-volatile memory by sending
a CK command. Note that the system will restart in the previous configuration even if it was
not saved with a CK command as long as the volatile memory’s internal battery is not
discharged. This can happen after several months without any power applied to the system
(Note that this battery will recharge as soon as power is reapplied). If the RiverPro/RioPro is
stopped by removing the power while pinging, it will restart pinging and output data next
time power is applied.
CR – Restore Command Defaults
Purpose
Resets the RiverPro/RioPro command set to factory settings.
Format
CRn
Range
n = 0 (User), 1 (Factory)
Recommended Setting
. Use as needed.
Description
The RiverPro/RioPro automatically stores the last set of commands used in volatile
memory. The RiverPro/RioPro will continue to be configured from volatile memory un-
less it receives a CR command or until the volatile memory loses its power.

Restore Command Defaults
Format
Description
CR0
Loads into volatile memory the command set last stored in non-volatile memory (user settings) using the CK Command.
CR1
Loads into volatile memory the factory default command set stored in ROM (factory settings).
CR keeps the present baud rate and does not change it to the value stored in non-volatile
memory or ROM. This ensures the RiverPro/RioPro maintains communications with the
computer.
