The Didactum Monitoring Systems 400 / 500 II (DC) / 600 / 700 are equipped with an SD card slot. These monitoring systems currently support SD memory cards with a capacity of up to 32 GB. Please use brand-name cards with Speed Class 10.
The Didactum Monitoring System 500/500DC/600/700 exclusively supports SDHC (Secure Digital High Capacity) cards. Using SD memory cards without HC is not possible. The SDHC cards must meet Speed Class 10 or higher. Please remove the SD card you are using from the Didactum 500 IT monitoring system immediately. Otherwise, the unsupported SD card will cause system malfunctions. We have recently tested 32GB SDHC cards with Speed Class 10 successfully. Please use only SDHC cards from well-known brand manufacturers.
