RPC-1  PC Remote System
  In Stock

Includes Programmable Timer Receiver, Wire, Remote + Battery

Designed for the common smart PSU with remote on, such as the ones from MP3Car.com.
Start your PC long before you enter the car or turn it on and off from the comfort of your home to synchronize files or use remote desktop.

Quick and easy install.  Splice the power (red & black) into your existing PSU or other constant battery source, cut the remote/ACC input wire and attach the green to the PSU and blue to the ACC or IGN wire you currently have connected.

Simply press a button to start your PC without a key, and a timer (Configurable from 1 minute to 45 days, or disabled) will turn the PC off if the key is not turned on within the time limit, or the PC is not turned off by remote.  Note: Most power supplies will cut power if the battery gets too low.  Keeping the timer at a reasonable time will ensure it shuts down properly.

Specifications:
   Quiescent current: 6.5mA
   Maximum Range: 650' (This is the MFR range)

 
  While the factory alarm in my car has a range of nearly 2' with the PC on, the aftermarket 1400' alarm gets around 500' but only 5-20' with the PC on depending on it's mood.
This PC remote has shown a reliable range of 380', hit and miss up to 450' surrounded by metal and tint.  Limited testing has shown a reduction of 10-15' at 10" from PC or Monitor.  Much higher loss at 3" from unshielded monitor, so keep it at least 1 foot away.

Other transmitters can be special ordered with ranges of 1600 ft, 3200 ft pocket sized, 1.25 mile, 2.5 mile large pocket sized.

Also, a 50 Ohm external antenna cable can be soldered to the board for increased reception.  Don't waste your money on remote systems that aren't tested with or made for a car PC system, or at least make sure you can return it.

Remote: Sleek design with sliding cover, antenna for extended range.
(W 1.5" x L 2.3" x H 0.6"  L 5.1" w/antenna extended)

RX: (W 1"  x L 1.9" x H 1") Keep antenna (short black wire) straight, outside of metal cases and away from devices that may cause interference.  Test multiple locations before permanently positioning.

 

 

4 Buttons:

  • A Key off: Turns the PC on, starts timer.
       Key on: Starts timer as soon as key is turned off, for gas fillups, quick trips into the store, etc.
        LED blips every 2 seconds to show timer is active.
        Press A before timer ends to extend time.
  • B  Key off: Turns the PC off.
  • D Tap: (Valet) Disables ACC(Key) input. Next A press enables it again.
       Valet mode is unaffected by vehicle battery removal. 
    Hold for 5 seconds (1st off-blink interval): Tap D for number of minutes x 10.  0 presses = disable timer.
    Hold for 10 seconds (2nd interval): Tap D for number of minutes multiplied.
    Program mode ends (LED turns off) if idle for 5 seconds.
    LED confirms (see B+D).
    Note:  Do not program while timer is active.  Due to the multitasking OS, the timer and program mode will both blink the LED.
  • B+D Display timer values.  Slow blink of multiplier, 1 sec pause, fast blink of minutes (default is 3 x 10 or 30 minutes).
  • C (yellow wire) is for optional negative momentary output suitable for a window rollup module, other alarm add-ons, horn, etc.  The output is held for as long as you press the button.  200mA max.  Use a relay (with clamping diode) for positive output or more current.  The 5V positive level can also be accessed.
 
ROEM-X OEM Keyless Entry Input Circuit
Update: Only N model available. Button is free!

In Stock

Options:  2ft. of color wire or .1" pin headers (straight or angle)
 
For OEM / aftermarket door lock / unlock or auxiliary outputs, and a smart PSU with remote on (ACC).

Before ordering, check the range of your remote first with your computer on. PC interference often reduces range.  This will affect turning the PC off, but not on.  Also determine positive or negative locks.  If you see 12V when pressing the buttons, get ROEM-P. If not, switch to continuity. AUX and aftermarket systems should cause a beep.  If so, get ROEM-N.


How it works:
Unlock:
   Starts PC without key in ignition and starts timer.
   Press again before timer ends to extend time (2-wire mode.  1-wire turns back off).
   Press with key on, turn key off to start stay-on timer, for fill-ups and such.
       (check if your alarm unlocks with the key on)

Lock:
   Shuts down PC if key off.

Button:
   Tap button to turn PC on or off with key off, starts timer.
   Tap button with key on, then turn key off to start stay-on timer.
   Tap again (or lock) with key off to turn PC off.
   Turn key on before timer ends to resume as normal.
   Press for 2 seconds (1st LED off-blink) to turn valet on or off. LED blinks 1 for off, 2 for on.
      (disables REM when key is turned on or doors are unlocked).
   Press for 5 seconds (2nd blink interval) to enter timer program mode (LED stays on).
      Then tap for number of minutes x 10 (default) up to 255 (42 hours).
      5 seconds of no input will end program mode (LED turns off).
      0 presses disables timer.
      LED will blink slow (minutes), pause, fast (multiplier).
   Press for 10 seconds (3rd blink) to change minutes multiplier.
      Then tap for number of times up to 255.
      Examples: 0x### = disabled, 1x1 = 1 min, 6x10 = 1 hour, 24x60 = 1 day
   Press and hold, then press unlock to toggle input mode.
       1 Blink:  1 wire input toggles PC on/off with unlock wire.  Lock wire always turns off (optional).
       2 Blinks (default): 2 wire input uses lock/unlock or 2 AUX outputs.


Connect power last.  NC/NO button and lock polarity is determined at power-up.
Connect (BLACK) - GND to Ground
Connect (RED)  +12V to constant power.
Connect (GREEN) REM to remote wire on PSU.
Connect (BLUE)  ACC to ACC or IGN (where original REM was wired)
Connect (YELLOW) UNLOCK to door unlock wire
Connect (WHITE) LOCK to door lock wire
Connect LED/Button GND (Black wire) to ground.

If you don't prefer the included LED button, there are many options. LED Illuminated buttons can run from $2.35 to $30, or a separate LED and button can be used.  Determine whether you want the button hidden or not.  The LED shows status for button presses, programming, timer activity and other things, so it's best to keep it visible.

For lock/unlock, using 1-wire toggle is much less intuitive in situations where the state of the PC can't be seen.  With 2-wire, pressing several times can insure the proper state if the remote is nearing out of range.  The lock/unlock triggers can be configured many ways. For example, if the system has 1 AUX output, it can be used as a toggle along with lock as a turn-off, or as 2-wire with AUX & unlock as on and off.

All settings are saved in EEPROM and can be pre-programmed by request.  Timer, valet, 1/2 wire are unaffected by battery removal.

Note: ROEM-N is triggered by grounding only. The source can be 12V or open. A positive trigger can be accomplished by use of a relay.

TMR-3  On/Off to Pulse with on-sense and on-delay
  
$19.95 (Purchase above)

Options when ordering:
  On-sense enabled/disabled
  Time scale (seconds, minutes, or hours)
  Output pulse width
  External button with LED

Example applications would be turning a laptop on/off with ignition, or turning a monitor on/off when the PC turns on/off while not getting out of sync. Plus a manual button.

Programmable delayed on-timer (disabled or 1 second to 18 hours):
  Hold button for 5 seconds. Tap for number of seconds. 0-255 (default 10)
  Hold button for 10 seconds. Tap for number of multiplier. 1-255 (default 1)
  Hold button for 15 seconds. Tap for number of output pulses. 1-255 (default 1) 250ms on, 250ms off.

Input 1 -> Source that turns on and off.
2-Wire Output -> The momentary switch to control.
Input 2 -> Device's internal power when on (2-20VDC).

When input 1 turns on, (immediate or after timed delay) generates a 250ms pulse if input 2 is off. (2 pulses per second)
When input 1 turns off, (immediate or after timed delay) generates pulse if input 2 is on.

Button tap pulses output always.
 
TMR-4  3 timers in 1. On-Delay and/or Off-Delay Timer
  
$19.95 (Purchase above)

The most popular timer here.

Delayed on timer for devices such automotive amplifiers, for anti-thump / speaker pop elimination.
Delayed off timer for extending powered time, ignoring short power-offs, or as a timed-on from a pulse.

Note: Use the same precautions as with most head units. Powering devices without a remote-on input may require a relay.  The maximum limit for remote-on inputs is 50mA and is typically much lower, so at least 4 amplifiers may be safely connected.  The standard Bosch automotive relay consumes 160mA, so this can safely power only one large clunky relay or several more efficient ones.

Input1 ON  starts on-timer, turns output ON at end of time
Input1 OFF starts off-timer, turns output OFF at end of time
Input2 ON or OFF starts off-timer (ignored if on-timer active) for instant or delayed off before source turns off.

Button tap manually toggles output and cancels timers.
  (Compatible with C output of above PC Remote - request "C wire")
Basic connection for amplifiers:
  GND (Black)      -> Ground
  +12V (Red)        -> Battery, or Input 1 source (No off-delay or manual switching)
  Input 1 (Green)   -> HU, USB, ACC, remote output, etc.
  Input 2 (Blue)     -> Optional: Turns output off with any transition
  Collector (White)-> +12V source normally
  Emitter (Yellow) -> Amp remote input

Programming:
   Hold button, LED will off-blink at 5, 10, 15, 20 second intervals. Release after 5 for option 1, etc.  Tap for desired number.  No input for 5 seconds ends programming, and confirms with on-time, off-time, multiplier. No input disables timer.

  1. On-timer (0-255 default 10)  (disable for pulse input to timed-on)
  2. Off-timer (0-255 default 10)  (disable for anti-thump if constant powered)
  3. Multiplier (1-255 default 1) Multiplies on and off timer by number of minutes/seconds.
  4. Second/Minute mode (tap once for minutes, none for seconds)

Ex (Seconds): On-timer 20, multiplier 5 =  100 seconds, 255x255 = 18 hours, 3 minutes, 45 seconds.
Ex (Minutes): 255x255 = 43 days and change.
