CarNetix CNX-P1290 V1.0 Installation Manual 2.2 Setting the Jumpers Note: Before adjusting the jumpers from their default positions, read the section on the SSC at the end of this document. There are 3 jumpers on the CNX-P1290. Below is a picture of their location on the board. You will need to remove the 4 screws that hold the lid, remove the lid, and disconnect the fan wire to get access the jumpers.
CarNetix CNX-P1290 V1.0 Installation Manual JP1 Jumper Settings Below is a table with the jumper selectable options for JP1. To move a jumper from its factory default position, use a pair of tweezers or needle nose pliers. Be careful to place the jumper in the correct position or erratic behavior could result. Double-check your settings before replacing the lid.
CarNetix CNX-P1290 V1.0 Installation Manual • DLYON Jumpering DLYON will turn your Secondary Output ON or OFF with the DLYON signal. This means that your Secondary Output will come on 3 seconds after your Primary Output comes ON, and will go off when you turn your ignition switch OFF. • PRI OUT Jumpering PRI OUT will make the Secondary Output follow the control used to turn ON and OFF the Primary Output. Thus, when the Primary Output is ON, the Secondary Output will also be ON.
CarNetix CNX-P1290 V1.0 Installation Manual 2.3 Connecting the Wires The CarNetix CNX-P1290 can be installed in a variety of ways, depending upon the system requirements. The primary target CarPC for the CNX-P1290 are the Casetronic (Travla) C13X series and the Cubid 26XX and 36XX series, with an internal Morex 60 Watt DC-DC PSU. The Morex PSU requires an input of +12V +/-5%, which is provided by Primary Output of the CNX-P1290. The +5V Secondary Output is typically used to provide power to USB devices.
CarNetix CNX-P1290 V1.0 Installation Manual 3.0 Option 1: “Power-only” to CarPC through existing case power plug This is the simplest connection configuration, and also the least functional. It merely provides regulated +12V to the CarPC and does not take advantage of the on-board SSC of the CNX-P1290. However, for the beginner (or faint of heart), it may be a good starting point.

CarNetix CNX-P1290 V1.0 Installation Manual Caution! Make sure you install a 15A fuse between your battery and the input to the CNX-P1290. This provides protection to your car’s electrical system should there become a short in either the wire from the battery to the CNX-P1290, or within the CNX-P1290 itself. This fuse should be placed as close as possible to the battery (within 6-12 inches) so that the long run of wire from the battery to the interior of your car is protected from short circuits.
CarNetix CNX-P1290 V1.0 Installation Manual Step 3. Run the Ignition Wire After the ground connection is installed, you will need to find the “ignition” wire. This wire is typically yellow and provides +12v when your ignition switch is on. Connect to this wire either by splicing into it and soldering the 3 wire-ends together, or by using a “T-tap” splice connector. You may have to search a bit for the ignition wire, but it can typically be found connected to your radio or head-unit.
CarNetix CNX-P1290 V1.0 Installation Manual Step 5. Connect the LCD Screen (optional) If you are powering your LCD screen (Lilliput or Xenarc) with the CNX-P1290, connect the optional LCD Power Cable Kit (Figure 4) to this same output from the CNX-P1290. Again, it is highly recommended that you SOLDER these connections and cover them with electrical tape to ensure a reliable, safe, long-term connection.
CarNetix CNX-P1290 V1.0 Installation Manual Note: the DLYON signal is NOT meant to provide POWER to your audio amplifier, head unit, or other auxiliary device. You must supply power through a separate wire from your battery to the auxiliary device. The DLYON signal is merely a control signal that tells the auxiliary device when to turn on. 3.
CarNetix CNX-P1290 V1.0 Installation Manual chances are your CNX-P1290 is not working properly, or there is no +12V power coming from the battery. Once you have inserted the input power connector and watched the Status LED blink, you may turn on the ignition switch. If all is working properly, you should see the Status LED flash rapidly for a few seconds as it enters the startup sequence. After approximately 3 seconds power should be turned on and available to your CarPC and LCD screen.
CarNetix CNX-P1290 V1.0 Installation Manual Step 4. Turning off your system. Since you are not using the SSC, you must manually turn off your CarPC BEFORE you turn off your ignition to prevent corruption of your hard disk drive (HDD). If your CarPC has booted properly and is currently running, press the Start switch on the front panel of your CarPC to initiate shutdown (you may also initiate shutdown through the normal Windows menus).
CarNetix CNX-P1290 V1.0 Installation Manual 4.0 Option 2: Power and SSC connection to case using existing case power plug This connection option takes full advantage of the SSC, but requires you to open the case to make the SSC connection to the motherboard. This option also uses the existing +12v input power connector on the case and requires the optional Case Power Cable to make the attachment. Many of the steps outlined in the previous installation option (Option 1) above are the same for this case.

CarNetix CNX-P1290 V1.0 Installation Manual Figure 9 Opening the C134 Case Once you have removed the outer shell, locate the jumper connector block labeled F_PANEL. (See the diagram below from the M10000 User’s Manual below to help locate this jumper). Remove the existing jumper cable that comes from the front panel Power Button (labeled PW_BN in the M10000 User’s Guide) and attach the CNX-P1290-P134-ACPI cable in its place. This cable attaches to pins 6 & 8 of the F_PANEL jumper block.
CarNetix CNX-P1290 V1.0 Installation Manual Figure 10 ACPI Motherboard Jumpers (F_PANEL) Once you have attached the connector to Pins 6 & 8, feed the two wires through one of the vent holes on the left-hand side of the rear panel so that they protrude outside the case. Now connect these wires to the ACPI and ACPI-Return wires from J2 on the CNX-P1290 (see Figure 8 above). If you find it necessary to extend the length of this connection, use 20 or 22Gage wire so that the signal will not be deteriorated.
CarNetix CNX-P1290 V1.0 Installation Manual 4.2 Applying power to the system (Option 2): Once you have installed the +12V battery cable, installed the fuse holder, connected your ground wire, connected your ignition wire, connected the case power cable, optionally connected your LCD screen, and optionally connected your remote devices, you are ready to apply power to the system Note: Before proceeding, make sure your ignition switch is turned OFF.
CarNetix CNX-P1290 V1.0 Installation Manual You should see the following sequence: 1) The Status LED on the CNX-P1290 will begin to blink for approximately 6 seconds (6 seconds is the factory default. If you have jumper-selected a different Shutdown Delay Time, the Status LED will blink for a longer period of time before beginning to shut down your CarPC. Please see the SSC section for further detail). 2) After the Shutdown Delay has expired, the SSC sends an ACPI shutdown pulse to the CarPC.
CarNetix CNX-P1290 V1.0 Installation Manual 5.0 Option 3: Power and SSC connection to case using internal power and SSC connections. This connection option is identical to Option 2 above, except for the +12V power connection to the case. In this connection option you will remove the existing rear-panel +12v power connector on the CarPC case and connect directly to the Morex PSU 2-pin power connector.

Connect these two wires to the RED (+12V) and BLACK (GND) wires on J2 of the CNXP1290.
CarNetix CNX-P1290 V1.0 Installation Manual 5.2 Applying power to the system (Option 3): This entire section is identical to Option 2 above with the exception of the discussion of case power connection as described above.
CarNetix CNX-P1290 V1.0 Installation Manual 6.0 Using the Pulse Start Feature The CNX-P1290 includes a new feature that allows you to remotely start and stop the PSU. This feature is called “Pulse Start”. This feature would normally be used in conjunction with a wireless device such as a car alarm with auxiliary inputs/outputs or a WiFi device with Wake-On-LAN (WOL) features. 6.
CarNetix CNX-P1290 V1.0 Installation Manual 6.2.3 Stopping the PSU with a pulse After the normal power up sequence, and while in Runs State, the SSC monitors the Pulse Start input for a shutdown pulse. If a single shutdown pulse is sensed, the PSU goes into the Shutdown Delay State. However, if control has been passed to the Ignition line (see Ignition Override below) the Pulse Start input is ignored. 6.2.
CarNetix CNX-P1290 V1.0 Installation Manual 7.0 CNX-P1290 Startup/Shutdown Controller The CNX-P1290 includes an intelligent, microprocessor-based startup/shutdown controller. The CNX-P1290 Startup/Shutdown Controller (SSC) provides safe, reliable control over your CarPC's bootup and shutdown (full shutdown or hibernation) processes. The chief concerns of the SSC are protecting your hard drive from corruption, protecting your car battery from being discharged, and protecting the PSU from overheating. 7.
CarNetix CNX-P1290 V1.0 Installation Manual 7.2.3 Bootup Lockout State After the CarPC is powered, the ACPI (PWRON) strobe is sent to the motherboard. At this point the SSC enters a "Lockout" state. In this state the SSC will not allow the PSU to be turned off until after a jumper-selectable Lockout Time period. This state is designed to prevent damage or corruption of a user's hard drive during bootup or shutdown by premature loss of power.
CarNetix CNX-P1290 V1.0 Installation Manual 7.2.7 Forced Shutdown State If the SSC detects either 1) a low battery (<10.5volts for >10seconds), 2) a fan fault, or 3) an Over Current condition, the SSC enters a Forced Shutdown state. During this state the SSC immediately begins a Shutdown Sequence without first entering the Shutdown Delay State. The Shutdown Sequence cannot be exited by turning on (or leaving on) the ignition.
