IR-712A Universal IR Learning Remote Module (Ver. 1.3, Aug/23/2016) 3
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-712A is a universal IR learning remote module which can learn IR remote
commands of diverse electronic devices. The learning commands (max. 224) can be
stored in the module or saved to a file. IR-712A 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-712A 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-712A is well-suited for smart home and
building automation.

2.4 Wire connection
The IR-712A supports 2 communication ports: RS-232 and RS-485 interfaces. Only
one interface can be used at the same time (*). Two IR outputs at the bottom are 3.5
mm audio jacks for IR emitter cables.
* Note:
1) Before the firmware v1.07 (included):
- Default serial interface is RS-232.
- Use IR utility to select RS-232 or RS-485 as the communication port.
- The TR/LN LED indications the current communication port after power-on within 3
seconds.
2) After the firmware v1.20 (included):
- RS-232 and RS-485 port of the IR-712A can be used without the utility configuration.
Though there is the setting item of the serial port in the IR utility, it won’t affect the
module.
- The TR/LN LED blinking 3 times after power-on within 3 seconds is for the function
of restoring to the default communication parameters.
2.4.1 RS-232 connection
The wire connection for IR-712A’s RS-232 port is shown in Figure 2-4.
Figure 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.
