Internal / External SIM-Card readers
The RTCU NX-200 device contains both an internal and an external reader. The external reader is
located on the front side of the unit (see graphical overview) for easy access. The SIM card reader
has a push/push eject system and a mechanical lock for secure installation of the SIM card. The
internal reader is located on the top side of the PCB board. It is possible to install a SIM-card in
both readers at the same time and switch programmatically between them from the application
1
.
Please refer to Appendix A for a SIM card installation guide. The RTCU NX-200 is prepared for
eSIM internally, which shares the SIM-card signals with the external SIM-reader. Please contact
Logic IO for this option.
It is possible to detect the state of both the SIM Insert and SIM lock status from the application.
Please consult the RTCU-IDE on-line manual for more information.
If the SIM-card is removed during the cellular operation, the device will be rejected from the
network shortly after.
Antennas
Cellular antenna
The RTCU NX-200 device contains an SMA female connector for connecting a suitable antenna.
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.
GNSS antenna
The RTCU NX-200 supports GPS, GLONASS, and QZSS so a suitable GNSS antenna must,
therefore, be used. The connection is with an SMA connector, and the GNSS antenna must be a 3V
active antenna with an SMA male connector.
Failing to use a suitable antenna may result in inferior performance, or spurious antennas short-
circuit detection.
When installing the antenna, please make sure that the antenna has a reasonable view of the sky,
so that it can receive the weak signals from the satellites. Please also consult the installation guide
that follows the antenna.
WLAN / Bluetooth Antenna
The RTCU NX-200 device contains an RP-SMA connector for connecting a suitable WLAN /
Bluetooth antenna. The WLAN and Bluetooth communication circuit shares the same antenna, so
only one single antenna is required.
