Q01 : How to solve the problem of text cut off in the utility?
A01 : This problem is only existed in Windows XP if the font size is changed to “large font” for
high display resolution. Please change the font size of the OS to “standard.”
Q02 : How to learn the Sharp-like IR commands of the devices successfully?
A02 : There is an space time of approximate 40 ms in the Sharp’s IR protocol. Please launch the
utility of the IR learning remote module and go to the “IR-xxx Basic Settings” window
(Menu->[Setting]->[IR-xxx Basic Settings]) to increase the “GapTime” to more than 40 ms. After
that, the IR module can learn the IR commands successfully.
Space time of Sharp’s protocol is about 40 ms.
Set GapTime > 40 ms to learn Sharp IR protocol.
Q03 : Why can’t the utility connect to the IR learning remote module though the serial
communication settings are correct?
A03 : Besides the serial communication settings of Baud rate, Parity, Data bits and Stop bits, it
is necessary to consider two other factors: Modbus Net ID and Serial Interface (RS-232/RS-485)
which the IR learning remote module applies. To determine the serial interface, restart the IR
module and check the TR LED status in the first 3 seconds.

If the RS-232 cable CA-0910 was connected to the IR learning remote module，please notice that
the Rx/Tx/GND pins of the CA-0910 should be connected to the Rx/Tx/GND of the IR module’s
RS-232 port accordingly as shown in the following figure.
Wire connection of the CA-0910 to the IR-210
When the USB-to-RS-232/485 converter was used with PC, please also confirm if the IR utility
opens the right COM port.

Q04 : How to reset IR learning module to the default serial communication settings?
A04 : Please follow the steps below to reset serial communication settings:
1. Change the wire connection to the RS-232 port of IR learning remote module.
2. Open the PC COM port connected to the IR module in the utility with arbitrary communication
settings.
3. Click menu [Setting]->[Reset Basic Settings on IR-xxx] to open the reset window.
4. Click the “Reset” button within 3 seconds after restarting (i.e. power cycling) the IR module. If
the reset is successful, a “Reset OK” window will pop up to show that the IR module is now
changed to default serial communication settings temporarily, which means the settings will be
restored to previous ones after cycling the power. To avoid it after power cycle, please go to
the “IR-xxx Basic Settings” window (Menu->[Setting]->[IR-xxx Basic Settings]) to set the settings
by clicking the “Set Permanently” button.

Q05 : What is the maximum length of the IR emitter cable for the IR-210/IR-712A?
A05 : It depends on the resistance and length of the cable. There is a DIY example of using IR
emitter cables with 100 meters long. Four IR emitter cables can be made from an Ethernet Cat5
cable with 4 twisted pair cables. They are applied to the application of controlling 4 air
conditioners in a luxurious mansion. The application diagram is as follows.
The length of the IR emitter cables (CA-IR-SH225x & CA-IR-SH225x-5) provided by ICP DAS are all
2.5 meters long. It is suggested to make the cables yourself if there is demand for a longer length.
The audio cable can be applied to extend the distance. For a longer distance like 100 meters, an
Ethernet cable is a suitable choice.
It is also noticed to buy the IR emitter diode (IRED) with IR wavelength 940 nm which is
commonly used in the consumer electronics. Please refer to the manual (Sec. 2.4.3) for the wire
connection among the IRED, the cable and the 3.5 mm audio jack plug, or as depicted in the
following figures.

Q06 :How to build IR remote application with the ICP DAS’s ISaGRAF PAC?
A06 :
Regarding the IR remote control with the ISaGRAF PAC, please refer to the link.
Please also refer to the ISaGRAP FAQ-152 for more details.
Q07 :Why can’t WISE-5800 controller connect to IR-712A?
A07 :
Please set the parameter “Modbus commands response delay time” of the IR-712A to 3 ms
(default = 1 ms) by IR-712A utility.
Steps:
IR-712A Utility’s menu [Setting] => [IR-712A Basic Settings] => [MB Cmd Resp Delay Time = 3 ms]
=> [Set Permanently]
Q08 :How to configure the communication to the IR-210/IR-712A in the WISE-5800?
A08 :
Take the IR-712A as an example.
➢ Communication Wire Conneciton
The WISE-5800 connects to the IR-712A by the RS-485 bus.
➢ Web configuration of the WISE-5800
(1) Press “1.Basic Setting” Button and “Modbus RTU Module Setting” button to show the page.
Set the Baud, Mode, Address and Name for communication to the IR-712A. Then, press “Add”.
(2) Add an IR-712A devices (IR-712A_1) as follows. Press “Setting” button for the IR-712A to set
