Approved Sd-Cards - Infranet Technologies M2M CONTROL CX320 Technical Manual

M2M Control CX320 Technical Manual V1.01
The SD-card features a push/push eject system for reliable insertion and operation. Please refer to
Appendix C for the Micro SD card installation guide.
Both the card detect and the write protect
application. Please consult the M2M Control IDE on-line help for more information. Avoid removing
the Micro SD card during access to the card.

Approved SD-CARDs

To ensure the highest performance and compatibility, it is important to use SD-CARDs approved and
tested by Infranet Technologies.
Commercial grade SD-CARDs can be used in applications where the limited write endurance is
acceptable - for example if the SD-CARD is often replaced. Commercial grade SD-CARDs should not
be used in applications where the media's potential failure is considered mission-critical.
For applications that extensively use the SD-CARD media and where a failure is critical, it is
recommended to use approved Industrial Grade SD-CARDs.
Infranet Technologies has approved and recommends industrial-grade SD-CARDs from ATP
available in capacities from 512 MB to 32 GB.
ATP Industrial Grade SD/SDHC Cards are optimized for demanding industrial applications with
consistent performance in all conditions. ATP uses reliable SLC flash technology with a flash
endurance more than 20 times higher than commercial grade products with MLC flash.
The differences in write endurance between commercial-grade MLC flash and ATP Industrial grade
SLC flash is quite remarkable for write-intensive applications:
