RTCU LX4 pro Technical Manual V1.00
Advanced Industrial M2M/IoT Gateway
SD-CARD reader
The RTCU LX4 pro device has a standard SD-card reader located on the device's top side (see the
graphical overview). The RTCU LX4 pro supports a FAT file system for standard PC compatibility. In
addition, SDHC cards with up to 32 GB capacity is supported.
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 RTCU 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 Logic IO.
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.
Logic IO 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:
