Page 4: Cnx-P1290 Installation Instructions
1.1 Overview The CNX-P1290 is a 90 watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs..including Travla & Morex cases, as well as many of the Sumicom and Xenarc PC systems. -
Page 5: Features
Whether you plan to use the on-board Startup/Shutdown Controller (SSC) or not, please read the section describing its operation first, before attempting to install the CNX-P1290. The SSC will affect the power turn-on and turn-off operation whether you use its features or not. - Page 6 CarNetix CNX-P1290 V1.0 Installation Manual - 6 -...

Page 7: Installing Your Cnx-P1290
CarNetix CNX-P1290 V1.0 Installation Manual 2.0 Installing Your CNX-P1290 Installing the CNX-P1290 involves 4 basic steps: • Identifying the connection points: • Setting the Jumpers: • Connecting the wires: • Turning on the system: 2.1 Identifying the connection points Figure 3 shows the location of J1 (Input connector) and J2 (Output connector). Note that J1 has 4 pins, while J2 has 6 pins. - Page 8 CarNetix CNX-P1290 V1.0 Installation Manual Figure 3 J1 and J2 Location - 8 -...

Page 9: Setting The Jumpers
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. -
Page 10: Jp1 Jumper Settings
Table 1 JP1 Settings Once the jumper selections have been made you may begin installing the wiring to connect the CNX-P1290 to your car’s electrical system, and to your CarPC. JP3 Jumper Settings (+5V Always ON) For those users who want to keep +5V USB devices powered even when the CarPC is OFF or in Standby, you can jumper Pin1 to Pin 2 on JP3. - Page 11 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.

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. -
Page 13: 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. - Page 14 CarNetix CNX-P1290 V1.0 Installation Manual Figure 5 Typical Connection Diagram - 14 -...

Page 15: Making The Connections (Option 1)
After running your primary power cable, attach a wire to the car’s metal chassis somewhere close to the final location of the CNX-P1290 and CarPC. Connect the other end of this wire to the BLACK ( pin 1) wire on the input connector (J1) of the CNX-P1290. Keep this wire as short as possible and make sure it is WELL GROUNDED to a METAL part of the car’s chassis. -
Page 16: Step 3. Run The Ignition Wire
You may have to search a bit for the ignition wire, but it can typically be found connected to your radio or head-unit. It is very important that you find the correct wire since the CNX-P1290 will not function if this wire is not connected or working properly. It would be a good idea to check, with your DMM, that +12V is indeed present when you turn your ignition switch on, and that it goes away when you turn it off. -
Page 17: Step 5. Connect The Lcd Screen (Optional)
Step 6. Connect auxiliary device(s) (optional). You may choose to use the CNX-P1290 to turn on power to your auxiliary devices such as audio amplifier, head-unit, or electric antenna. In this way, these devices are powered only when the CNX- P1290 is ON and providing power to your CarPC. -

The number of blinks represent the software version and revision in the SSC. The blink code now includes Software Version (ie 2 blinks) followed by a “dot”... -
Page 19: Step 3. Applying Power To Your Carpc And Screen
Step 3. Applying Power to your CarPC and Screen Once you have verified that the CNX-P1290 is producing +12V (+/-5%) at its output, it is time to plug in your CarPC and screen. Insert the connector J2 into the CNX-P1290 and the case power plug into the case rear panel power connector. -
Page 20: Step 4. Turning Off Your System
Once the CarPC has fully shut itself down, you can then turn off your ignition switch. The CNX-P1290 will go through its normal shutdown process and eventually turn itself off (after the jumper-selectable Shutdown Delay time plus Boot Time). -

Where they are the same, please refer to the installation details given in the previous option. To install the CNX-P1290 in this configuration you will run 3 wires into the unit (+12v battery, Ground, and Ignition), one case power cable consisting of two wires (+12VDC, Ground) out of the unit to the case, and two wires (ACPI and it’s return ground wire) to the ACPI/PWRON jumper on... - Page 22 CarNetix CNX-P1290 V1.0 Installation Manual Figure 8 Typical Connection Diagram - 22 -...

Page 23: Making The Connections (Options 2)
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. - Page 24 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. The polarity of the connection is not important since this output is driven from a set of relay contacts which simply short together when the ACPI pulse is sent from the P1290.
- Page 25 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.

(screen, mouse, keyboard, etc) so that you can verify that it is properly booting and operating. Once you have verified that the CNX-P1290 is producing +12V (+/-5%) at its output, it is time to plug in your CarPC and screen. Insert the output power connector, J2, in to the CNX-P1290. Insert the case power plug into the case rear panel power connector. - Page 27 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.

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. -

PSU from overheating. 7.1 Hibernate/Standby Operation The CNX-P1290 supports both Hibernate and Standby operation of your CarPC. This option is jumper selectable with Pins 5 & 6 on JP1. When supporting Hibernation the P1290 completely shuts down all power to the CarPC after the Shutdown Lockout State. -
