Testing decoder installs using PR3?

[mfm37]

 PR3 is current limited just like the program outputs on a DCS command station so it's safe for testing.

Note that an Empire Builder system does not have a current limited programming output so a 100 ohm 1/2 watt resistor should be added in series to one of the program track feeds to make it safe for testing decoder installs.

Hi,

I understand that the 'traditional' way of testing whether a DCC decoder install is correct is by trying to program the address on the programming track.  Having replaced my programming track with a standalone section connected to a PR3, I was wondering if using the 'identify decoder by reading it' functionality of Decoderpro is also safe? (i.e. it has the limited current that the programming track does).

Thanks in advance,

I use it this way all of the time with no issues.  Having the standalone track with the PR3, is one big advantage of the PR3.  I also use the throttle to test functionality like lights, sounds and motor control.  I generally can get get the motor to turn before the current limiting kicks in but it lets me know everything is working fine.
