CarNetix CNX-P1290 V1.0 Installation Manualchances are your CNX-P1290 is not working properly, or there is no +12V power coming from thebattery.Once you have inserted the input power connector and watched the Status LED blink, you may turnon the ignition switch. If all is working properly, you should see the Status LED flash rapidly for afew seconds as it enters the startup sequence. After approximately 3 seconds power should be turnedon and available to your CarPC and LCD screen. Three seconds later, a remote-turn-on signal is sentto your auxiliary devices (ie power amp). If you have access to their power indicator light, nowwould be a good time to see if it is ON.Once you have applied power to the CNX-P1290, and you feel comfortable that it is wired andworking properly, you can measure the voltage at its output connector (with that VOM you bought)to verify that it is indeed producing +12V before you attach the power cable to your CarPC. Becareful not to short out the output!Before proceeding, turn off your ignition switch and verify that the CNX-P1290 turns off properlyafter the Shutdown Delay and the Boot Time have expired. These times are jumper selectable andare initially set to 6 seconds (Shutdown Delay) and 30 seconds (Boot Time). This means that CNX-P1290 will continue to provide power for 34 seconds (minimum) after you turn off the ignition. Ifyou have configured the Shutdown delay for a longer period, or if you get impatient, you can simplyunplug the input connector to turn the unit off more quickly (don’t do this while your CarPC isconnected since power will be immediately removed).Step 3. Applying Power to your CarPC and ScreenOnce you have verified that the CNX-P1290 is producing +12V (+/-5%) at its output, it is time toplug in your CarPC and screen. Insert the connector J2 into the CNX-P1290 and the case power pluginto the case rear panel power connector. Optionally, insert the LCD screen power connector into theLCD screen power connector. Note that the case power plug is slightly larger than the screen(Lilliput) power plug.Now, turn on the ignition switch. Since you are not using the SSC, you must manually push the Startbutton on the front panel of the case to turn it on. Push the Start button now. You should hear/seeyour CarPC starting. Also, push the ON button on your LCD screen. Your CarPC should beginbooting and soon you should see the welcome screen on your LCD.If this is NOT what you see….. Houston, we have a problem! If your PC is booting, butdoesn’t look right, try to turn it off by pressing the Start button again. If this doesn’t send itinto shutdown, turn off your ignition switch. This will remove power after the ShutdownDelay and the Boot Time (see SSC section for definitions of these). This will abruptly shutdown your PC and may cause HDD corruption. Do this only if things don’t look right and asa last resort.If you have connected auxiliary devices, they should be ON at this time also (after a 3 second delay).At this point the full system should be ON and operating normally.- 19 - |
