notes for [VEMS Audi AAN] (with JPT/55 connector).

- this is very important '''when deviating from factory (VR/auditrigger) setup
- it is even more important if the wrong part was ordered (request "AAN ECU with HALL/HALL trigger" in the order comment: without this, the factory
- even more important if ordered multiple ECUs with the wrong type (factory VR/auditrigger instead of requesting HALL / HALL)
- it is super-important if any complications appear (eg. no complete success with the first home-converted device).
For HALL / HALL sensor, a supply voltage is needed. +5V supply is included on JPT55/pin48.
- This was requested by customers applying custom solution: HALL / HALL trigger. Those who order HALL / HALL type (because using nonstandard trigger setup) usually know what they are doing.
- This way +5V can be easily made available for the HALL sensor (but care might be needed, to not plug in VR sensor, or short to GND)
- [paper] is included with HALL/HALL device that explicitely mentions this +5V
- see [1] for some AAN v3.9 illustrations] that might be of help to get some idea about the differences of standard VR/auditrigger setup, and when "AAN ECU with HALL/HALL trigger" requested
- keep in mind that any device is customized from base-board (not first making VR/Auditrigger and than converting to HALL / HALL).
- eg. SJ7 must be closed for sectrig auditrigger, not for HALL (so HALL / HALL type didn't mention SJ7 originally because it can be left open: needs to remove solderblob if converting from VR/Auditrigger)
- make sure to download latest version (eg. "SJ7 open" was added to HALL / HALL)
In case of any problem (or suspected problem), follow
- [Tech request]
- eg. specify intent (eg. "I accidentally ordered the standard type with factory trigger, and want to convert device srl/... from oid/...) from ... to ...
- detail what modifications made (yes, step-by-step, even if repeating some docs)
- measurement results (eg at JPT55 and sensor pins)
- photo of result
- triggerlog (with annotation, eg. I think sectrig does not appear)
- for convenience, you can do it on this page for now. We'll clean it up later
If a conversion is not success, do NOT duplicate.
