MUX_SH board mod tutorial

Postby e-licktronic » Oct 30th, '17, 15:15

Dear Diyer,

Here is a tutorial on how to mod your Nava with Mux_SH boards.

1/You must unsolder IC111 and IC114

Image

If you don't have a good desolder iron you can cut each pin then unsolder pins one by one

Image

2/You must unsolder C517, C518, C519, C89 (BD), C163 (SD), C164 (LT), C165 (MT), C166 (HT), C167 (RS), C168 (HC)

Image

3/Solder J15 connector

Image

4/Solder IC111 and IC114 Pins Headers

Image

5/Solder CMS components on both Mux_SH boards. Take care of IC orientation, the 45°line have to match red line

Image

Image

6/Cut three piece of jumper wire female/female in the middle

Image

7/Solder wires on the Mux_SH board. Take care to to put the same wire color on the pin +, GND and -

Image

8/Solder Pin headers on the MUX_SH boards

Image

9/Connect both MUX_SH board to the Main board. Take care IC111 and IC114 are in the opposite way.
And connect Jumper wires to J15

Image

10/Now update the Nava firmware v1.024 (or higher) by holding steps button 1, 3 and 5 when power up the unit

Old accent value are still saved in your old pattern, to get it working properly you must write new pattern ;)
Enjoy

Is it related to this post?
Also, if it works for the NAVA, would it work for the Yocto2? Assuming firmware update?

Yocto² doesn't need Mux/SH board cause accent works perfectly ;)

Ok, sorry for the misinterpretation, but from your post it was not clear that you are offering built ones. And peskado very much likely built his own Nava and will therefore get the boards for free from e-licktronic.

For unexperienced users with second hand machines it could still be pretty tricky to install the new MUX_SH boards, as they require desoldering the old ICs and fitting new sockets into the pads.
