Daikin EWWD340CJYNN [22/28] Appendix 1 software upload to the controller

Appendix 1: Software upload to the controller

It is possible to upload the software into the controller using two different ways: using the direct download form a

personal computer or using the Carel programming key.

Direct upload from a PC

To upload the program, it is necessary to:

• Install the program Winload in the PC. It can be requested from Daikin.

• Connect the PC, via a RS232 serial cable, to the RS232/RS485 converter (cod. 129150083)

• Connect the RS485 converter port to the controller terminal port (J10) using a 6-wire phone cable (terminal cable)

(cod. 129150041).

• Disconnect the controller from pLAN and set the net address to 0.

Switch on the controller and run Winload, select the correct serial port number you are using and wait (a few tenths of a

second) for the “ON LINE” status (this means that the program is connected to the controller).

Then select the “Upload” folder and the “Application” section and select all program files supplied by Daikin (one file

in the “blb files” box and one or more files in the “iup files” box).

Then press the “Upload” button and wait until the transfer is completed; the program shows the progress of the transfer

phase in a window and when the process is completed the “UPLOAD COMPLETED” message will appear.

Finally turn off the controller, disconnect it from the PC, reconnect the pLAN and set the right net address.

This procedure has to be applied to all controllers on the unit.
