SW update

7-4. How to update the Micom(UART)

t

Update SW through RS232(UART) communication.

Step 1

Power down the unit and prepare to connect download cable to the PCB 
* 20 pin connecter in black color(ODU - 10 pin connecter)

Step 2

Execute S-net pro 2 and go to Add-On tab and click UART Update button

USB to RS232 cable

S-Converter

t

UART update  can be used for direct SW update to the hardware.The UART update can be used for SW update of indoor/outdoor/MCU.

We need to connect the S-Net Pro2 to the device board "Download" connector through the download cable.

t

S-Net Pro2 serial communication should be disconnected. If it is on connection, please disconnect by "Disconnect" button in "Home" ribbon   

tool bar. When it is still connected, "UART update" button is disabled. 

t

This feature is applicable in the Disconnected Mode only.

▶ 

Procedure 

1. Connect the indoor/outdoor/MCU board through the download connector.

2. Open S-Net Pro2 and do not click “Connect” button

2. Click on the "UART update".

4. The update window pops up.
