Hello TEAMS,
We have been made aware of an issue with one of the Gear Tooth Sensor boards in the sensor array strip from the kit of parts. R3 and R4 as noted are swapped. After some evaluation it was found the original Bill of Materials we were given to build from had the placements incorrect on one board. After we got ahold of the schematic, the switch was confirmed. All is well now from a systems end, but we must help out you teams. If any of you feel comfortable making the swap, then have a go at it. For the rest of you who do not, we will swap the two resistors for free.
To have your board repaired, please send the board to Diversified Systems, Inc, Attn: Ben Wrightsman, 3939 West 56th St., Indianapolis, IN, 46254. For questions, you can contact me directly at 317-299-9547 x350. We, the diversified systems, inc. crew will repair the board and return it to you promptly. Again, if you have the resources, skill sets,and are comfortable making the repair yourself, you're more than welcome to do so.
***NOTE, only one of the two gear tooth boards has this issue. Picture attached. If you look at the resistors under magnification the correct R4 should read "1001" and R3 should be "1004" The board with J4/J5 is the only incorrect board ***
One question I would like to ask, what team caught this issue? If I can get reply with their name, Team#, and contact we will send them a special gift. You caught something that two large companies have missed for 2 years until now. We want to reward you for that feat.
thank you,
