ALERT205 OS/Web Interface

v2.01

Current ALERT205 operating system and web interface.

ALERTLink software/firmware requirements:

ALERT205 UI (version 2.00 and greater) requires that AL200 use ALERT2 OS 6.0 or newer firmware/OS
ALERT205 UI now only works and is tested with CR300 firmware/OS CR3XX.Std.11.01.obj (included in this package)
CELL2XX internal modem users will need to double check their settings prior to applying any changes to their ALERT205.

Revision History

v2.01October 10, 2025

(NOTE) ALERT205 systems using a Maxon radio and an AL200 with firmware version 6.0 should set their Modulation Voltage to 750. There is a bug in the AL200 firmware and this works around the issue.
(NOTE) SDI12Watch is not working in the released version of the CR3X0 datalogger operating system. This will be corrected in a future release.
Major
Added PakBus Encryption Key and Pakbus/TCP Password settings to better allow customers to secure their stations.
Major
Added Ethernet Comm device to support ALERT205 systems that contain a CR310 data logger.
Major
Fixed an issue with the platform not requesting Time Service when the logger's clock or the IND device didn't have valid time via GPS.
(feature) Added ClimaVUE50G2 meteorological sensor.
Minor
Fixed an issue getting the IND revision information. The temp string wasn't being cleared making it so the information displayed at times was incorrect.
Minor
Fixed an issue where the clock of the datalogger might not sync correctly in some corner cases.

v2.00January 24, 2025

Major
Updated CRBasic program to use AL200 ALERT2 API v2.0 API commands.
Major
Fixed broken MSR4 reporting.
Minor
Updated UI to match new Campbell Scientific, Inc. branding.
Minor
Added support for the AL205R IND device.
Minor
Added Center Transmission and TDMA Slot Padding to AL200 settings.
Minor
Fixed App Test Flag. It now reports test transmissions correctly with the AL200's test button is pushed or when the Trigger button is pushed in the user Interface.
Minor
Added if Trigger Test TX button back to the dashboard (hidden during AL200 OSv6 development).
Minor
Units conversion handling was updated for the following sensors. Please review your units selection if your system is reading from any of the following: * WaterLog - Amazon Bubbler * WaterLog - H-350XL Bubbler * WaterLog - H-3611 Radar Water Level Sensor * CS475, CS475A Radar Water Level Sensor * R.M. Young - 86000-SDI Ultrasonic Anemometer.
Minor
Fixed minimum Destination Address that was set incorrectly to allow a bad alert address of 0. Now set to a minimum address of 1.
Minor
Added IND device firmware information to the Dashboard to aid with troubleshooting [AL2XX Status]. AL205R does not support API polling for this information, so we add, by hand, the details when this device is used.
Minor
Fixed Generic Float Switch to use the EX2 port instead of the C2 port to conserve power and meet sensor power requirements.
Minor
Fixed Serial port wait times to meet the CR300's serial port specifications.
Minor
Fixed an issue with the GPS when the CR300 does not get a response from the IND device.
Minor
Added better validation and reporting of responses from IND device for time and GPS.
Minor
Updated the wiring diagram and generated CRBasic program for the Water Level (Generic Float Switch).
Minor
Check AL200 settings on occasion just in case the AL200 loses power and goes back to default settings. We no longer write settings to the AL200 to keep from wearing out its memory.
Minor
Ensure we have good time from the GPS, if the change is greater than 24 hours it is ignored (unless on initial startup). Sometimes the GPS (older modules) in the AL200 gets bad time data.
Minor
Added a note to some bubblers warning users to connect the 12V of the sensor to a battery instead of to the listed terminal in the GUI. This was done in cases where the bubbler pulls more amperage than the ALERT205 device could support (current limits).
Minor
Adjusted defaults to be as specified in the ALERT2 IND Standard v2.1 (September 2024) except Carrier Only Time and Hop Limit.
Minor
Carrier only time now defaults to 5 milliseconds even though the ALERT2 standard recommends setting this to 0. There is a bug in the AL200 firmware V6.0 the prevents the use of 0 milliseconds. 1 millisecond is the lowest setting that should be used with a AL200 with firmware v6.0.
Minor
Added RangeVUE15 and RangeVUE30 SDI-12 water level sensors.
Minor
Fixed grammar in several help text messages.
Minor
Fixed MSR4 reports that were sending data in m/s instead of km/hr.
Minor
Fixes an issue with MSR reports where an air temperature was always required for a MSR3 or MSR4 report.
Minor
Adjusted the multiplier for the 05103-L sensor to be 0.2192 so it will be mph instead of m/s.
Minor
Fixed wiring color for Water Level (H-305XL) sensor.
Minor
Fixed an issue with (05103-L) Wind Speed and Wind Direction values that are sent via ALERT2. We were sending possibly old values instead of the latest recorded values.

v1.8February 5, 2024

Minor
Fixed an issue in the CRBasic program with getting seconds since 2010 status.
Minor
Added better logic for handling an issue when time returned from the AL200 is from the future.
Minor
Changed the GPS_Sensor_ID variable in the CRBasic program to be a Const instead of a variable. There is an issue with PreserveVariables in the CR300 datalogger that makes it so that the ALERT2 GPS sensor ID can't be changed after initially running the program.
Minor
Adjusted for serial buffer in CR300 datalogger.
