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.
