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.

1.7 Installment
•Locking screw method: Use M4 for direct screws-fittings (see below).
•Installing and dismantling aluminum DIN rail: Attach the back trench of the device to the mounting rail in
arrow ①direction and push the device against the rail in arrow ②direction. To dismantle, first push
down the device in arrow ①direction and follow arrow ③direction to release the device.
