Quad-Pic Auto Programmable Servo Decoder
[tvd-qpc002]

Use to control four turnouts using model R/C style servos. Servos are easily mounted under the turnout and provide a reliable and inexpensive method to switch points. the Quad is very versatile, you can move the points by DCC commands from your throttle, use buttons on the fascia, control from a signal system or any combination of the 4. LEDs can be hooked up to indicate the direction of throw. DCC - The unit can be completely programmed from the buttons and LED indicators on the board or you can use programming on the main to set the CVs. The DCC address is easily programmed by setting a jumper and then issuing the desired accessory address from your throttle. This avoids the confusion of how DCC Accessory addresses are stored in the CVs. Power - The board has a beefed-up and separate regulator circuit for the servos to eliminate power loss to the microprocessor. The best way to power the board for DCC is to use the specially designed DCC Accessory booster which can power up to 6 Quad-Pics. For DC use any power supply from 7.5-18V AC or DC can be used. It is also possible to supply 5V power directly to the servos. The servos are completely opto-isolated to prevent ground loops. Expansion - The new design has provisions for adding daughter boards to expand the capabilities. One daughter card has relays for switching the frog power or controlling some other accessory. Another daughter board lets you add on stall-machines (such as the Tortoiseâ„¢) - you can still use the servos at the same time. Signals - Inputs for signal systems have been added. An expansion board that provides full opto-isolation of the signals is available soon.
