| Rigol DS1054Z rotary encoder mod *works!* |
| << < (20/28) > >> |
| klausES:
I am trying to find out whether the encoder ordered does not exactly match the one mentioned here. The ALPS EC12E2424407 often mentioned here differs from my ordered, if at all, only a little bit from the mechanical properties and dimensions but it should be the same from the electrical side (I hope ...) :palm: It is an Alps STEC12E08 rotary encoder, 24 pulses / 24 detents, vertical. Find only a very bad datasheet of this STEC12E08 ... At the moment it is not quite sure whether I might have caught a defective encoder when ordering. :P As it is now, I cannot leave it. 50% of menu items can only be selected between two stop points ... :-- |

The two should really be the same encoder type. In the STEC08 datasheet, you will find the other model number right on the title page, under „model“. |
| klausES:
And I already had doubts because the STEC12E08 is funny to buy only from a single dealer across the country and this type does not even appear in the manufacturer list on the Alps website ... :-\ Not even Mouser or Farnell think of this type. But why do I have the problem that two menu items are jumped per click? :-// Unfortunately I had not tried the encoder with the older firmware. Since the update to 04.04.04.03 I have not come back to the previous 00.04.04.04.02 to test the encoder. |

Hmm, my (old) DS1054Z is still at 04.04.04.02. Unless Rigol changed the way their firmware update works, you can't go back to an older firmware version unfortunately. Can anybody confirm that the .03 version (didn't realize it exists) also works with the detented encoder? Of course Rigol could in principle also have transitioned to a different encoder for the latest PCB redesign, and/or flipped the connections to the two quadrature signals in their PCB layout. As you can see in the STEC08 datasheet, one of the quadrature phases is always stable at the detent position, while the other is "right on the edge" there. Maybe it's worth a try to swap the two connections to your replacement encoder (via short bodge wires between the part and the PCB), and see whether the encoder is better-behaved then? |
| klausES:
Unfortunately I only bought one STEC12E08. Otherwise, I could have quickly compared this type with the original from rigol. (Don't want to stress the PCB with lots of soldering now). I found this in the documentaries of these Alps encoders (see picture in the appendix). According to this graphic, the correct parking position would not be given for the EC12 "E", but for the type EC12 "D"?!? |
