1.1 Introduction
Thank you for choosing Delta IFD8540 module. Before using the module, please read this manual for
proper installation and operation.
The IFD8540 is a Bluetooth communication module that provides MODBUS (RS--232/RS-485) conversion
to Bluetooth and vice versa. You can create software configuration with Delta communication software
HWCONFIG 4.0 via RS-232/RS-485/USB.
The characteristics of the IFD8540 modules are as follows.
1. Support MODBUS protocol.
2. Isolate communications from power, strong noise immunity.
3. Use the external control button for Bluetooth group, MODBUS station or combination of particular
communication format and baud rate.
4. Support using Reset button to restore default values.
5. Provides communication lighting (BLE, COM) control to easily detect errors.

3.1 Software Configuration
3.1.1 Software description
Users must install two basic software - HWCONFIG 4.0 and COMMGR before operating the modules. The
main function of COMMGR is being the medium software between a PC end and a device that manages
communication interface of devices, while HWCONFIG 4.0 is for setting module parameters.
3.1.2 Procedures
Step 1: Add IFD8540 communication interface in COMMGR. For communication type, select
RS232/422/485 and the name is IFD8540 or choose an easily identifiable name. When setting is complete,
close COMMGR window but the software continues to operate with graphic shown in the system list.
Step 2: Next, click HWCONFIG 4.0
Step 3: Create a new project.

Step 4: For device option, choose IFD8540 and the HWCONFIG4.0 loads the default parameters of the
device. Please refer to chapter 2 for parameter details.

Step 5: Before operating the software, choose Communication Setting under Operate tab and choose
the channel that is already setup in COMMGR.
Users can click Upload under Operate tab to view IFD8540 parameters on the software. In addition, click
Download to write modified parameters in IFD8540. Please use online mode to check IFD8540 firmware
version. The IFD8540 does not support the scanning function of the software.
3.2 Parameter Settings
Module parameters contain IFD8540 parameters and BLE (Bluetooth Low Energy) parameters. Both
parameter categories is divided into Basic and Advanced settings. The Basic is defined as parameters
modified via a button and is controlled by DIP- switch (DIP1); when DIP is ON and the button parameter is
within legal range, the system adopts the button value or use the software value instead. As for Advanced,
the software downloads and controls its parameters.
In the parameter list, the value that is different from default uses another color for display.

3.2.1 Basic setting
The IFD8540 controls serial communication parameters and the basic setting includes button and DIP-
switch parameters.
Name
Description
MODBUS slave ID
1. The IFD8540 slave ID. When RS-485/232 receives slave ID
commands for MODBUS, IFD8540 auto-responds and does not
transfer via Bluetooth.
2. In corresponds to SID button, MODBUS slave ID is set when DIP1
is OFF or DIP1 is ON and SID is 0x00.
Replace slave ID function
1. When enabled, the IFD8540 Bluetooth interface will not respond to
slave ID commands for MODBUS but transfer the commands as
replaces slave ID via serial communication and send the response
back to MODBUS master.
2. Enable from IFD8540 slave. Setup replace slave ID in Advanced
parameter setting, default value is 1.
3. When DIP1 is ON and DIP2, DIP3 is also set to ON, the function is
enabled.
RS485 protocol
1. Converts MODBUS ASCII and MODBUS RTU, accepts only
MODBUS commands.
2. When Bluetooth connection uses RS485, select transparent
transmission mode and the command content is not restricted. All
received data is send via Bluetooth.

3.2.2 Advanced setting
The IFD8540 controls serial communication parameters, but Advance setting does not provide button or
DIP-switch and becomes effective once settings are complete without using DIP-switch.
