Recorder Commands
The recorder contains approximately 16 megabytes of solid-state nonvolatile memory, which can be used
to record data. If more data is collected than fits in the memory, the newest data will not be recorded.
Once the recorder fills up, the recorder MUST be erased before re-deploying the RiverPro/RioPro (start
pinging again).
If the RiverPro/RioPro is set to record data (
) and the recorder is full, the RiverPro/RioPro
will
not
start pinging and will return a
RECORDER NOT READY
message.
Using the recorder will slow down the RiverPro/RioPro’s ping rate.

ME – Erase Recorder
Purpose
Erase the contents of the loop recorder.
Format

Recommended Setting
. Use as needed.
Description
ME ErAsE erases the recorder memory. To make it more difficult to accidentally erase the
data, the word “erase” must be typed with exactly one space after the “ME” (which is not
case sensitive) and with alternating upper and lower case letters, as shown.
Once erased, data is not recoverable.
Erasing the loop-recorder will take several minutes, and no status updates are provided
during the erase process. When complete, the status will be displayed on screen as shown
below.
