Deltang Prog4 is the latest and most versatile programmer from the company so far. It can be used together with a PC computer and a download cable (Please see PL2303 link on this page). Prog4 should work with Rx4x, Rx6x and Rx10X receivers manufactured after October 2013. Prog4 create a wireless link between the computer and the receiver to change receiver settings.


Programming the receiver is done by downloading a single file to the Prog4. File to download is presented below. File name is not important. Only the first 3 lines of the file (between type3 and end) are important. Deltang suggests to use CoolTerm software to perform the transfer.

other examples:

Programmer must be bound to the receiver at least once to remember it for later programming.
