Field firmware upgrade for your CarNetix
U-Flash (tm) allows you to upgrade your firmware
by using an inexpensive PIC programmer which
can be purchased online. All of the details
of the process are outlined HERE. Make sure you carefully select the appropriate
firmware to download that matches the revision
(version) of your hardware PC board. This
Version number can be found on the top of
the PC board in white lettering.
Here is an example of the PCB Version 1.2
Once you have determined which PCB version
you have, you can download the new firmware
If you only want to tweak certain parameters
in your current firmware CLICK HERE.
P1260 V1.x users - Please Note:!!
If you are downloading firmware for the P1260
version 1.3 and plan to use the Standby Mode,
YOU MUST READ THE PRECAUTIONS BELOW, otherwise
you may destroy your CarNetix product. It
is very important that you understand the
potential issues involved by using Standby.
The CNX-P1260 supports both Hibernate and
Standby operation of your CarPC. This option
is jumper selectable with Pins 5 & 6
When supporting Hibernation the P1260 completely
shuts down all power to the CarPC after the
Shutdown Lockout State. However, if Standby
mode is selected, the P1260 continues to
provide +12V after the Shutdown Lockout State
is completed, but turns off its fans to conserve
power. This has several very important ramifications.
1) In Standby your CarPC continues to receive
+12V power from the P1260 so that it can
retain the processor state in RAM. If for
some reason the CarPC did not properly shut
down when it received the ACPI shutdown pulse
from the P1260, it will continue to draw
current from the P1260. THIS WILL CAUSE THE
P1260 TO OVERHEAT AND POTENTIALLY SELF-DISTRUCT.
You MUST make sure your CarPC properly enters
the Standby State before you exit your car.
If you don't, you may return to your car
surrounded by the local fire department.
2) Any USB devices connected to your CarPC
via the USB connector will continue to draw
current in the Standby state. THIS COULD
POTENTIALLY DRAIN YOUR BATTERY IF THE CURRENT
DEMAND OF YOUR USB DEVICES IS VERY HIGH.
Exercise caution when using USB devices in
the Standby mode.
Standby should only be used after you fully
understand the above points. If you do not
understand the above information, DO NOT
USE THE STANDBY MODE.
