Update SCS 500 & 600 Controller firmware
How to update firmware for your SCS 500 & 600 Controller using the Field app.
Update process
Firmware can be updated from either the mobile or desktop app. The steps are the same for both.
- Disconnect the cooler from the power source then open the Field app on your phone or desktop.
- Open the menu in the top right-hand corner and select UPDATE FIRMWARE.
- Select the CLOUD STORE option to access the firmware files.
- Under FILE LIST, choose the firmware version you want to update (eg. 1593_9 bin(74176)) and click DOWNLOAD.
- Wait for the app to confirm the download is complete, then click OK.
- Select LOCAL FILES and confirm the file you have downloaded there.
- Press START SCAN then connect the cooler to the power source (see picture below). The Bluetooth indicator on the face of the SCS Controller will flash once successfully connected.
- Select the SCS controller model you want to update from the list displayed on the app. Press SELECT IMAGE FILE.
- Wait to see the firmware then click START UPDATE to start overwriting (or reflashing) the previous firmware version.
- Wait until the reflashing status reaches 100%. You should see a message "Firmware Update Complete” then click OK.
The firmware should now be successfully installed on the SCS controller.
