Using the transmitter for the fi rst time
In the “Port select” window you can now select the 
correct COM port, i.e. the one to which the USB in-
terface is connected. This can be identifi ed by the 
name “Silicon Labs CP210x USB to UART Bridge” in 
the “Device Name” column; in the screen-shot above 
this would be the “COM 3” port.
Now call up the “HoTT Module Upgrade option un-
der “Menu”, open the “Controller Menu” and click on 
“HoTT Module”:
Click on the button labelled “File Browse” and select 
the desired fi rmware update fi le (with the suffi x “bin”) 
in the “Open fi le” dialogue which now appears.
The fi rmware fi les are present in a product-speci-
fi c encoded form, i.e. if you inadvertently select a fi le 
which does not match the product (e.g. receiver up-
date fi le instead of transmitter update fi le), the pop-
up window “Product code error” appears, and the up-
date process cannot be started. 
If you have not already done so, switch the transmit-
ter OFF at this point and start the transmitter update 
procedure by clicking on the “Download Start” button. 
Wait until the progress bar starts running. This can 
take up to several seconds. Now switch the transmit-
ter ON with the BIND-Button pressed. After a few se-
conds, the status display „Found target device ...“ 
appears. Now release the BIND-Button. The actual 
update process now commences, and a progress bar 
starts running:
Do not interrupt the update process until the progress 
bar has reached the right-hand margin, and you see 
the message “Firmware Download Success” - also a 
a brief buzzer sound appears and the STATUS-LED 
of the transmitter changes from orange to green:
