Logger Cannot Be Updated When Connected to a HW2 Base Station

Logger Cannot Be Updated When Connected to a HW2 Base Station

In certain installations, a logger may be unable to communicate with a BaseStation and therefore cannot receive software updates through the normal cloud update process.

This occurs when a legacy Hardware Version 1 (HW1) logger operating on Software Version 5.2 is installed in a system using a Hardware Version 2 (HW2) BaseStation operating on Software Version 8.0.

Because communication cannot be established between these devices, the logger cannot receive the software update required to bring it to a compatible version.

Symptoms

You may be experiencing this issue if:
  1. A logger appears offline despite being within communication range of the BaseStation.
  2. The logger does not receive available firmware or software updates.
  3. Data transmission from the logger cannot be established.
  4. The logger is operating on Software Version 5.2.
  5. The BaseStation is operating on Software Version 8.0.

 Cause

As part of normal product lifecycle management, SCADAR introduced Hardware Version 2 (HW2) Bluetooth communication hardware.

A known compatibility limitation exists between:
Device
Version
BaseStation
HW2 / SW 8.0
Logger
HW1 / SW 5.2

In this configuration, communication between the BaseStation and Logger cannot be established.

As a result, the logger cannot receive the software update required to migrate to Software Version 6.0 through the standard cloud update path.

Compatibility Reference


The following compatibility scenario is affected:

BaseStation: HW2 / SW8.0
Logger: HW1 / SW5.2

WarningThis combination cannot communicate.

How to Identify Affected Devices

If you are unsure whether a logger is HW1 or HW2, the hardware generation can be determined from the product serial number.

Hardware generation can be determined from product serial numbers.

The following serial numbers represent the first HW2 device manufactured for each product family:
CMC SCADAR Part Number
Product Serial Number
Y11SCAD02 - SCADAR BaseStation
SN00000507
Y11SCAD14 - Current & Volts Logger (800 A) CS.800.A
SN00001841 
Y11SCAD15 - Pressure Logger (16 bar) PS.16.Bar
SN00000986
Y11SCAD16 - Temperature Logger TS.200.CEL
SN00000052
Y11SCAD17 - Flow Logger FS.220.mm
SN00000118
Y11SCAD18 - Dewpoint Logger DS.-80.CEL
SN00000057
Y11SCAD19 - 4-20mA Logger GP.4-20mA
SN00000101
Y13SCAD02 - Pressure Logger (60 bar) PS.60.Bar
SN00000059
Y15SCAD02 - Current & Volts Logger (50 A) CS.50.A
SN00000090

How to interpret the serial number

As a rule:
  1. Serial number below the transition point = HW1
  2. Serial number at or above the transition point = HW2

Resolution

The affected logger must first be upgraded using a compatible HW1 BaseStation.

Upgrade Process

1. Confirm the logger is:
  1. HW1
  2. Software Version 5.2
2. Confirm the site BaseStation is:
  1. HW2
  2. Software Version 8.0
3. Obtain access to a compatible HW1 BaseStation.
4. Update the compatible HW1 BaseStation to SW8.0. This will update the logger software on that BaseStation to Version 6.0 or later.
5. Connect the affected logger to the HW1 BaseStation.
6. Allow the logger software to be upgraded to Version 6.0 or later.
7. Return the logger to service on the HW2 BaseStation.
8. Verify normal communication and operation.

Expected Result

Following a successful upgrade, the configuration should be:
  1. Logger HW1 SW6.0
  2. BaseStation HW2 SW8.0
Communication is restored and the logger can continue receiving updates through the normal cloud update process.

Frequently Asked Questions

Why can't the logger be updated directly?
The logger must first communicate with the BaseStation in order to receive the update.
In the affected configuration, communication is not possible, preventing the update from being delivered.

Is this a hardware fault?
No. This is a known compatibility limitation affecting legacy HW1 loggers operating on Software Version 5.2 when used with HW2 BaseStations operating on Software Version 8.0.

Do all HW1 devices have this issue?
No. This issue only applies to loggers operating on Software Version 5.2. Once upgraded to Version 6.0 or later, normal communication is restored.

Is there an alternative update method?
No. The approved migration path requires temporary use of a compatible HW1 BaseStation.

Further Assistance

If you are unable to determine the hardware version of your equipment or require assistance performing the upgrade, please contact SCADAR Support and provide:
  1. BaseStation serial number
  2. Logger serial number
  3. BaseStation software version
  4. Logger software version
This will enable us to confirm whether the installation is affected and advise the appropriate upgrade path.

Recap

Here's a quick summary:

⚠️ HW2 BaseStation / SW8.0 + HW1 Logger / SW5.2 – These devices cannot communicate.
✅ Resolution – Connect the affected HW1 logger to a compatible HW1 BaseStation.
✅ Upgrade – Upgrade the logger to Software Version 6.0 or later.
✅ Return to service – Once upgraded, reconnect the logger to the HW2 / SW8.0 BaseStation.
✅ Result – Communication is restored and the logger can continue receiving updates through the normal cloud update process.
