IR-712-MTCP Universal IR Learning Remote Module (Ver. 1.8, Dec/11/2020) 3

1. Introduction

IR-712-MTCP is a universal IR learning remote module which can learn IR remote commands of diverse electronic appliances. The IR learning commands can be stored in the module or saved to a file. IR-712-MTCP supplies 2 IR output channels for individual or simultaneous control on multiple appliances. The Ethernet interface with Modbus/TCP and Modbus/UDP protocol provides more flexible expansion and control on the module. Besides, the software utility provides users with easy configuration, IR learning, test and storage of IR commands on the IR-712-MTCP. As a replacement of IR remote controls and a module that can be easily integrated with Modbus client devices (e.g. PAC, PLC, PC… etc.),

IR-712-MTCP is well-suited for smart home and building automation.

2.6 Slide Switch for Firmware Update/Default Communication

There is a slide switch at the right side of the IR-712-MTCP case for the firmware update / default communication mode.

◼ Caution:

(1) Firmware update filename of the new IR-712-MTCP (with “RevB” labeled on the front

case) : “ir712mtcp_RevB_v###.dat”

(2) Firmware update filename of the old IR-712-MTCP : “ir712mtcp_v###.dat” (3) It should use the special firmware files to update the new RevB/old IR-712-MTCP, or

the wrong file will damage the hardware.

2.6.1 Update firmware / Default Communication

Please put the slide switch to the FW/Init position as depicted in the Figure 2-8. Power cycle the IR-712-MTCP to enable the FW/Init mode. The TR/LN and PWR LEDs will both blink 6 seconds long (can start update firmware) and then go to the state with TR/LN LED off and PWR LED on. The module is in the default communication settings (basic settings) now for the condition of forgetting the communication srttings in the firmware operation mode. The module can be updated firmware at this state, too.

(a) Please refer to the Appendix A for the procedure of firmware update.

Note: The basic settings and the stored IR commands will not be changed after the

firmware update.

4.3 Learning and Testing IR commands

Follow the steps below and the illustration in figure 4-6 to learn and test IR commands:

(1) Determine the IR command for learning by selecting the items in the “Device Name”

and “Command Name” comboboxes.

(2) Click the “Learn On” button to enable the IR learning mode on the IR-712-MTCP. At the

same time, the TR/LN LED is turned on to show the Learn On state.

(3) Aim the IR emitter head of the device’s remote control at the IR input of IR-712-MTCP.

The distance less than 3 cm between the remote control and the IR-712-MTCP would be best. Then, press the button of the remote control which is to be learned. If the

learning for the IR command is finished, the TR/LN LED will be turned off. (4) Select the IR output channel. For example in the figure 4-6, the IR output channel is 1. (5) Aim the head of the IR emitter cable plugged in the IR output 1 at the corresponding

IR-controlled appliance. Click “Run Command” button to emit the IR command from the

IR-712-MTCP. You can check if the learned IR command is OK by investigate the action

of the appliance. If not, please repeat step 2 and step 3 again. (6) Click “Save this Cmd” button to save this IR learning command to the current item of

the “Command Name” combobox, e.g. the item is “Play” in figure 4-6. (7) Repeat the above steps (1) ~ (6) to learn all the IR commands.

5. Modbus Registers Addresses

Table 5-1 is the description of the Modbus holding registers (4xxxx) for the IR-712-MTCP. The Modbus client device can send Modbus commands to the IR-712-MTCP to emit the IR commands from the output channels. The function codes (FC) of Modbus to write data to Modbus registers are 6 and 16. Each Modbus address occupies 2 bytes. (Modbus TCP/UDP Port = 502)

Table 5-1 Modbus Holding Registers in the IR-712-MTCP

Start Address [4xxxx]

Description

1103 (0x44F) [41104]

1104 (0x450) [41105]

IR output channels. Valid value: 0x01 ~ 0x03。The first bit (LSB) of the value

represents the 1st channel. The 2th bit represents the 2th channel.

Example :

‧The 1st output channel：0x01 == 01 (Binary) ‧The 1st and 2nd output channels：0x03 == 11(Binary)

Table 5-2 is the example of a Modbus FC16 command to emit IR signal from the IR-712MTCP. (Modbus ID:1, IR command No.:1, IR output channel: 2)
