In the figure
there is displayed the detail of NB-K868 module printed circuit board with configuration connector
with the location of the configuration connector (bordered in red), the SIM card holder (marked in purple), the
NB-IoT uplink antenna connector (marked in blue), the 868 MHz reveiver antenna connector (marked in light blue)
and the battery switch (marked in yellow) on the opposite side of the board. The serial number on the module
label must always correspond to the serial number on the auxiliary label affixed to the printed circuit board (data

The case of NB-K868 module consists of two parts:
•
housing of the module to which the printed circuit board is inserted. On this part of the box there is a label,
circular peephole for the magnetic attachment of the USB-IRDA / BT-IRDA converter, cable gland with
bushing, and mounts (mouldings) for mounting the module;
•
box cap that covers the housing. There is a second cable gland on the cap.
To install a module that is already assembled (including both antennas), preconfigured and turned on, follow these
steps:
•
attach the module to a suitable firm object (wall, pipe) by four screws or by a clamping tape. There are
mounts by the casing bottom side intended for the attachment. The recommended position of the mounted
module is vertical, with the with the lid underneath;
