RE: [tracker2] Re: Tracker2 with LCD display
- Hi John,
Here are the parts.
WM8181-ND, right angle header
WM2525-ND, terminal housing
WM2512-ND, crimp terminal
I have all the parts and the crimper so it was not much of an effort. A
simpler route might be to solder 6 inches or so of greater than 8-conductor
wire and terminate it in a 9-pin Dsub connector. The only advantage the my
cable has is I can remove it and have no extra pigtail.
In the picture you see can the ribbon cable that is used for the LCD.
Because the terminal just slides on the header, vehicle visitors have
unplugged the LCD unintentionally. That requires me to open the case and
reconnect it. Next time I have it open I will locked it in place somehow.
In case anyone is interested, the 3-headed cable is for the GPS, PC and
GTRANS out. The 9-pin dsub on the back on the radio is not connected. It is
left over from when the radio/TNC cable was used for a KPC3+ and that was
the GPS connector. The upper right face is a TK-981 (900MHz) sitting idle.
Its twin brother is actually running elsewhere in the vehicle.

Do you happen to have a MFG name/part number for the 16 pin
right-angle header and cable connector shown in these pictures?

Fred tells me the following in an email "The LCD has a particular startup sequence and this will only be done at the T2 startup."
Whereas, I took the WIKI quite literally "No configuration is necessary. The standard Tracker2 firmware will begin using the display automatically. "
So, I just plugged it in, hot. What a newbie mistake!
