When installing the antenna, please make sure that the antenna is not in close proximity to metallic
parts or anything else, that can influence the efficiency of the antenna. Please consult the
installation guide, that follows the antenna
SD-CARD reader
The RTCU NX-200 device has a standard SD-CARD reader which is located on the bottom side of
the device (see graphical overview) The RTCU NX-200 supports a FAT filesystem for standard PC-
compatibility with up to 32 GB capacity support.
The SD-CARD features a push/push eject system for reliable insertion and operation. Please refer
to Appendix B for an SD-Card installation guide.
Approved SD-CARDs
To ensure the highest performance and compatibility, it is important to use SD-CARDs that has
been 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 a potential failure on the media is considered mission-critical.
For applications that use the SD-CARD media extensively and where 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
that is 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:
