1. Introduction
The Intelligent Home and Building Automation are becoming the hot topics recently in
the world. Many countries are devoted to development and promotion in this field.
There are many kinds of consumer electronics and home appliances in the market
applying the IR remote control function because of its mature technology and low cost.
However, these appliances are usually equipped with their own remote controls using
diverse IR protocols which are not unified to a standard. If these IR commands of
different appliances can be collected and integrated to the control interfaces, it is
possible to implement the automation application for a better living experience.
IR-712 is a universal IR learning remote module which can learn IR remote commands
of diverse electronic devices. The learning commands can be stored in the module or
saved to a file. IR-712 supplies 2 IR output channels for individual or simultaneous
control on multiple devices. The accompanied RS-232 and RS-485 interfaces with
Modbus/RTU protocol provide more flexible expansion and control on the module.
Besides, IR-712 software utility provides users with easy configuration, learning, test
and storage of IR commands. As a replacement of IR remote controls and a module
that can be easily integrated with Modbus master devices (e.g. PAC, PLC, PC… etc.),
IR-712 is well-suited for smart home and building automation.

2.4 Wire connection
The IR-712 supports 2 serial communication interfaces: RS-232 and RS-485 ports.
Only one interface can be used at the same time. The default interface is RS-232 port.
2 IR outputs at the bottom are 3.5 mm audio jacks.
Note: The IR-712 utility can help users to change the serial communication port (RS232/RS-485). The TR/LN LED can indicate which port is used in the beginning 3
seconds after power-cycling the IR-712.
2.4.1 RS-232 connection
The wire connection for IR-712’s RS-232 port is shown in Fig. 2-4.
Fig. 2-4: RS-232 wire connection.
Please refer to Fig. 2-6 if the RS-232 connection cable (e.g. CA-0910, Fig. 2-5) is
applied. If there is no DB9 serial port on the host PC, it is recommended to use USB to
RS-232 converter (e.g. I-7560 or I-7561) to extend the serial port.
