• LED is switched on by log. 1 on the C6 pin of TR module.
• Relay contact is closed by log. 1 on the C7 pin of TR module.
The DV-SW1-05 demo example works with examples for remote controllers RC03 or RC04. The DV-SW1-05
receives commands and switches the relay on if the "S1" packet is received and off if the "S2" packet is received.
The LED indicates that the relay contact is closed. Demo example can be downloaded from
Typical application
The TR module should be uploaded out of the DV-SW1-05 case in an external programmer. Wireless upload
(RFPGM) is also possible. To enable this, the user must ensure a way to switch the TR in RFPGM mode, e.g. by the
enableRFPGM() function (the TR is delivered with this option disabled).
It is not allowed to operate the device with the case opened.
