2.DESCR PT ON
LBT-1.GW1 Modbus RTU Bluetooth gateway is designed to operate with any PC or any PLC controller
if they support Modbus RTU RS485 communication. Beside default 115.2kbps/8N1, also other
communication settings are supported. If PC computer cannot direct support RS485 communication,
it's possible to use appropriate USB RS485 adapter, for example: Smarteh LS -2 adapter.↔
For each Samrteh LBT-1 product e.g. radiator valve actuator, window/door sensor,..., there is a
description of Modbus RTU commands in corresponding user manual. Using this commands,
communication with nodes can be established, after LBT-1 nodes are successfully provisioned to the
Bluetooth MESH network.
Example of Modbus RTU commands:

4.OPERAT ON
LBT-1.GW1 Modbus RTU Bluetooth gateway can operate with Smarteh LBT-1 products and with other
vendor Bluetooth Mesh product while provisioned to the same Bluetooth Mesh network. Bluetooth
Mesh vendor model of the individual product must be obtained from the vendor. t the same time it
must also be connected to the PLC controller or PC, supporting Modbus RTU RS485 communication.
For each Smarteh LBT-1 product e.g. radiator valve actuator, window/door sensor,..., there is a
description of Modbus RTU commands in the corresponding Smarteh LBT-1 product user manual.
Using this commands, communication with nodes can be established, after LBT-1 products are
successfully provisioned to the same Bluetooth Mesh network.

4.1. Other Modbus RTU Bluetooth gateway functions:
• Factory reset: This function will delete all Bluetooth Mesh network parameters stored on the
LBT-1.GW1 gateway and will restore to the factory default condition. LBT-1.GW1 gateway will be
ready for provisioning. See Table 7 for more information.
4.2. Operation parameters
LBT-1.GW1 Modbus RTU Bluetooth gateway connected to the main control device like Smarteh
LPC-3.GOT.012 or similar, transmits and receives following general operation codes listed in table
below. For operation codes related to the individual Smarteh LBT-1 Bluetooth product, please see
the corresponding LBT-1 user manual. ll communication between PLC based main control device as
LPC-3.GOT.012 or similar is performed by using Modbus RTU communication. Individual Bluetooth
Mesh node configuration data should be observed by using Bluetooth network provisioning tool.
4.3. Modbus RTU settings:
Default Modbus RTU settings: Slave ID 234, Baudrate: 115200 bps, Parity: None, Stop bit: 1.
Slave ID is set by DIP switches S3, S4, S5.
Default Modbus settings are applied when DIP switches S3, S4, S5 are set to “0” position. When DIP
switch is set to other position, user defined Modbus RTU settings are applied.
Do not use smaller Modbus RTU poll times than 100 ms.

NOTE: If LBT-1.GW1 Modbus RTU Bluetooth Mesh gateway is not connected directly to the Smarteh
LPC-3.GOT.012 main control or similar device using male-female connectors, twisted pair extension
cable should be used. The LBT-1.GW1 gateway must be placed separately from other electrical
appliances and cable must be installed separately from high power and high voltage wires in
accordance with general industry electrical installation standards.

6.1. nterference warnings
Common sources of unwanted interference are devices that generate high frequency signals. Those
are typically computers, audio and video systems, electronics transformers, power supplies, various
ballasts, frequency converters and similar. The clearance distance from the LBT-1.GW1 gateway to
the any of above mentioned devices should be at least 0.5 m or greater.
W RNING:
• In order to protect plants, systems, machines and network against cyber threats, it's necessary to
implement and continuously implemented state of the art security concept.
• You are responsible for preventing unauthorized access to your plants, systems, machines and
networks and they are allowed to be connected to internet only, when security measures like
firewalls, network segmentation, … are in place.
• We strongly recommend the updates and usage of latest version. Usage of version that are no
longer supported may increase the possibility of cyber threats.
