5. After entering all K values press . This initiates a validation
of the entered values. (Do NOT press softkey. Pressing the
key results in no saving of data in the ODO Cal K values. ODO
Cal K values will not be changed.)
When invalid calibration code data is entered, the below message appears.
6. If no validation error message is displayed, the ODO calibration codes
were entered correctly. to save and return to run screen.
Notes:
- It is not necessary to load sensor cap coefficients when a new ODO probe is
installed. A new cable/probe assembly has a sensor cap installed and the sensor
cap coefficients are preloaded into the probe at the factory.
- If ODO calibration codes are not uploaded when the sensor cap is replaced
the ODO may not operate accurately.

Downloader/Updating 5X00 Firmware
Like all microprocessor based instruments, it may be necessary to upload revisions
to 5X00 firmware. Download new firmware using the Flash Programmer utility in
AquaManager. A serial RS232 connection is necessary to run the Flash Program-
mer utility.
The instrument firmware may get corrupted if any of the following occurs during
a 5X00 firmware update:
- Firmware Updater window utility is closed;
- AquaManager is closed;
- RS232 cable is removed from 5X00 or PC com port;
- power is disconnected from 5X00.
If the 5X00 firmware becomes corrupt and is not updated properly, it may be neces-
sary to return the instrument to YSI .
Firmware Updater Directions
1. Wire RS232 connection. See RS232 Communication - page 68. (Dis-
regard if already using RS232 connection.)
Note:
Connect RS232 directly into slaves in order to upload firmware to slaves.
Disable slaves at the master to avoid slave failure alarms when uploading
- Menus → System → Communications → Network →Master.
2. Enable the Force Serial Port on 5X00s wired and configured with an
ethernet device - page 102.
3. Verify that the baud rate in 5X00 Communications menu is configured
to 115200.
4. From the AquaManager Explorer window, access the Flash Programmer
utility from the pull down menu: Tools→ Instrument tools→Update
Firmware.
