Radio channels
The wireless communication utilizes the IEEE 802.15.4/ 2.4GHz band which is shared with Wi-Fi
networks. These networks can disturb the communication between lock and hub. Before the RACS AIR
network is configured it is necessary to verify which channels are occupied by local Wi-Fi networks
and to select a channel or group of channels which are the least used. Radio channel scanning can be
done with commonly available apps.
Note: Due to their nature, wireless systems are exposed to all kinds of interferences. The
communication can be affected by ambient electromagnetic radiation and periodic disturbances. Radio
communication can also be intentionally suppressed. Therefore in RACS 5 system, the Emergency
mode was introduced to enable lock operation when wireless connection is lost. If the Emergency
mode is not configured in RACS 5 AIR system then there is a risk that mentioned disturbances will
affect the system and hinder its operation.

Low level configuration
Low level configuration is used to define device parameters for particular applications and conditions
as opposed to high level configuration which is used to define logic of access control system. The low
level configuration of RWH-1 hub and other wireless devices of RACS 5 AIR system is done with
RogerVDM software and RUD-1 communication interface.
Programming with RogerVDM software:
·
Place jumper on MEM pins.
·
Connect RWH-1 hub to RUD-1 interface using dedicated cable with connector (fig. 2).
