1. Introduction
The LC lighting control module is easy-to-use and requires no specialist skills to install
and operate, and no software is needed in order to control the lighting control channels.
The LC-101H is a 1-channel lighting control module with AC load current measurement
which provides 1-channel high power relay output and 1-channel AC digital input.
The LC-102H is a 2-channel lighting control module with AC load current measurement
which provides 2-channel high power relay output and 2-channel AC digital input.
The AC load current measurement is provided in the relay control loop. This function not
only allows the user to know the load current value, but also through the measurement
of the load current value, it can be used to know the switching state of the relay, whether
the load is working normally in the light control loop, or the relay is stuck and cannot be
switched.
The input channel can directly control the relay ON and OFF sequence without the host
command.
When required, the module can be communicated with the Modbus RTU protocol, and
an added benefit is that different addresses can be set for Modbus RTU communication
via hardware configuration.

3. Configuration via RS-485
The factory default settings for RS-485 communication
Address: 1
Protocol: Modbus RTU / DCON
Baud rate: Hardware Configuration: Fixed 9600 bps
Software Configuration: 1200 to 115200 bps
Data Format: N,8,1/O,8,1/E,8,1/N,8,2
Note
If there are multiple LC-101H/LC-102H connected to the same RS-485 network,
each module needs be set with a unique RS-485 address. More than one module
having the same address will cause communication failure
Testing RS-485 Communication

ICPDAS web site : https://www.icpdas.com/en/download/DCON_Utility_Pro
2. Launch the DCON_Utility_Pro.exe.

10. Click the module name to configure the logger.
Note
The Protocol/Baud Rate/Parity/Checksum items marked with ”(INIT*)” means that
when any of those items needs be modified, the pin 4.INIT needs to be set in ON
position and power cycle the logger, then the item can be modified.After complete
setting, set the pin 4. INIT back to OFF position and power cycle the logger again to
take the setting effect.
