The P5V installs easily into the P1900 or P2140 using only a Phillips screwdriver. The output wires may be attached to your existing hub power cable by simply connecting two wires. Page 5 CarNetix CNX-P5V V1.2 Installation Manual 1.3 Before You Begin Before you begin the installation, make sure you take the time to read through these instructions. The CNX-P5V is a simple switching regulator, but proper installation is required to prevent damage to your system and to achieve optimum performance. Page 6 CarNetix CNX-P5V V1.2 Installation Manual 2.0 Installing Your CNX-P5V 2.1 Installing the CNX-P5V in a CNX-P1900 The P5V can easily be installed inside the CNX-P1900 using only a Phillips screw driver. Now would be a good time to make any P1900 jumper settings since the jumpers will be somewhat hard to adjust after the P5V is mounted. Page 7 CarNetix CNX-P5V V1.2 Installation Manual The P5V PCB should be mounted with the TOP of the regulator IC pointing DOWN as shown below. The white lettering of the P5V PCB will be facing UP as shown here. This will leave 2 jumper pins open. Bend the metal connector upward slightly. USB hubs and devices come with various sized power connectors. Radio Shack has a particularly good selection of plugs and adapters that will fit most USB devices. Shown here is an example of the Radio Shack adapters connecting an Audigy 2NX sound device plus a Belkin USB hub.

Polarity does not matter.http://ecocj.com/userfiles/20200914031536.xml Be careful to keep the wire close to the PC board to prevent it from interfering with the fan. Replace the lid and 4 mounting screws. Double check your wiring to make sure it is not touching the fan blades. This completes the installation of the P5V in the P2140. When using the P5V as a stand-alone POL you will need to make sure there is adequate heat dissipation for the regulator IC.

ThisThis feature would normally be used in conjunction with a wirelessThe externally applied voltage pulse is connected to Pin 1 of J1Voltage Pulse on Pin 1 of J1The SSC will wait (hang) if the voltage stays high without going back. The current required to drive this input is very low (milliamps).The SSC will waitThe current passing through this relay is very small (milliamps) so a low power relay can be used. Pulse Width. The pulse width can be any value from a minimum of approximately 100mSec to several seconds. As mentioned above, if the pulse is very long the SSC will wait for the transition back to the normalWhen the PSU is in Idle State (both LEDs off) and an externally applied pulse is applied to the Pulse. Start input, the PSU will power up normally, as it would if the Ignition line had gone high. DuringAfter the normal power up sequence, and while in Runs State, the SSC monitors the Pulse Start inputIf 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.If, while in the Shutdown Delay State, a single pulse is detected, the Shutdown Delay is restarted atThis is useful for occasionallyOnce the Shutdown Delay has timed out, the PSU enters the Shutdown Lockout State. At this pointIf two pulses are detected within a 5 second window during the Shutdown Delay State the PSU willThis feature is useful for shutting down the CarPC when your file transfer process is completed.If, after the PSU has been started by a pulse, the Ignition is turned on, control is passed to the. Ignition line. Once the Ignition line has gained control of the SSC it will be able to shutdown the. PSU as if it had initially started it. This feature is useful when you wish to remotely start the CarPCThe chief concerns of the SSC areThe CNX-P1290 supports both Hibernate and Standby operation of your CarPC. This option is. When supporting Hibernation the P1290 completely shuts down all power to the CarPC after the. Shutdown Lockout State. However, if Standby mode is selected, the P1290 continues to provideIf for some reason the CarPC did not properly shut down when it receivedWILL CAUSE THE P1290 TO OVERHEAT AND POTENTIALLY SELF-DISTRUCT. You. MUST make sure your CarPC properly enters the Standby State before you exit your car. If youUSB devices in the Standby mode. Standby should only be used after you fully understand the above points. If you do not understandWhile idle, the SSC monitors your car battery while waiting for the ignition switch to be turned on. If the battery is below approximately 10.5 volts, the SSC will not allow the CarPC to boot. If theWhen you turn on your ignition, the SSC briefly (approx. 3 seconds) enters the RunDelay state. During this time the SSC checks to make sure the battery is stable, the ignition stays on, and thenAfter the CarPC is powered, the ACPI (PWRON) strobe is sent to the motherboard. At this point the. In this state the SSC will not allow the PSU to be turned off until afterThis state is designed to prevent damage or corruption ofThe Lockout Time isThis allows users who have configured their. CarPC for hibernation to enjoy a faster shutdown sequence (30 seconds) than those who have their. CarPC configured for full shutdown (90 seconds).After the Lockout period ends, the SSC enters the Run state. During this time your CarPC is runningUnder normal conditions, you exit the Run State eitherAfter normally exiting the Run. State, the SSC enters the Shutdown Delay State.After you turn off your ignition, or apply a remote pulse, the SSC enters a Shutdown Delay state. This state allows you to keep your CarPC running for a jumper selectable time after the ignition isDuring this Shutdown. Delay State, turning the ignition switch back on will cause the SSC to re-enter the Run State andAlso, a remotely applied pulse can either prolong the Shutdown. Delay State, or send the PSU immediately into Shutdown Sequence State (see Section 6 Remote. Start Pulse). When this Shutdown Delay time has elapsed, the SSC enters the Shutdown Sequence state (seeThe SSC timing is designed to accommodate the use of the ACC wire instead of the IGN wire to. The SSC has a minimum 6 second delay to accommodate this temporary interruption in inputThis delay willAt the beginning of this state the SSC issues an ACPI (PWRON) strobe to the motherboard.
