2 Configuration Variables used by the P2K-SW9 Deoder Configuration variables are the 'offiial' name for adjustable parameters in the deoder CV1 Short address. Valid values range from 1 to 127. CV2 Vstart. This value added to all speed steps of the "fatory speed table", 1 ount = about 1% of full voltage when using the normal speed table. If the uploadable speed table is used the perentage varies with the frequeny of PWM motor ontrol in CV9. CV3 Aeleration rate (eah unit = 32mS between speed steps) 254 ma. Available in 14/28 speed modes only. CV4 Deeleration rate (eah unit = 32mS between speed steps) 254 ma. Available in 14/28 speed modes only. CV9 PWM frequeny. This CV determinesthe total PWM period for the uploadable speed table. Eah unit = 128uS this allows a frequeny of 30hz to 279hz. 279hz omes from using eah speed = 1 ount this yields: ma speed = 28*128us for a 3.58mS period whih equals 279hz. CV17 ong address high order 6 bits bit 6,7 always= 1 bits 0-5 are upper 6 bits of 14 bit address CV18 ong address low order byte CV19 Consist address. 8 bit address, when ative the onsist responds to all ommands addressed to it the same as it would to it's normal long/short address. Note: the normal long/short address is still ative for all non-speed/diretion ommands (espeially useful for headlight and other funtion ontrols of individual loomotives while in onsist). If the onsist address is set to 0 or 128 then the onsist is inative. bits bit onsist address (1-127) bit 7 0= onsist diretion is normal, 1= onsist diretion is reversed CV23 Aeleration adjust. This value is added to the value in CV3 at power up or when reprogrammed CV24 Deeleration adjust. This value is added to the value in CV4 at power up or when reprogrammed CV29 Deoder Configuration byte - bit 0 1= diretion of operation is reversed, 0= diretion is normal - bit 1 1= use 28 speeds mode, 0= 14 speed mode - bit 2 1= Analog onversion enabled. 0 = disable analog mode - bit 4 1= use alternate (uploadable) speed table, 0= use normal speed table - bit 5 1= use long address (CV17,18) do not use CV1, 0= use short address CV1 not CV17,18 - bits 3,6 and 7 are not used Table of ommonly used values for CV29 Value for CV29 ong/short Uploadable/Fator Analog 14 or 28 deimal he Address y Speed table Conversion Speed mode 0 0 Short Fatory no Short Fatory no Short Fatory yes Short Fatory yes Short Uploadable no Short Uploadable no Short Uploadable yes Short Uploadable yes ong Fatory no ong Fatory no ong Fatory yes ong Fatory yes ong Uploadable no ong Uploadable no ong Uploadable yes ong Uploadable yes 28 Note: If you want the loomotive to operate in the opposite diretion inrease the indiated value for CV29 by one.

3 POGAMMING TACK INFOMATION: This deoder omplies with NMA P for both paged mode and register mode programming. Ops mode programming (Programming on the Mainline): Deoders do not respond to the long form ops mode programming instrutions at their onsist address (per P-9.2.1). Tip for using onsists and etended addresses: leave CV1 set to 3, or some other onveniently remembered address and only use the etended address (CV17, CV18) set to your desired value. This avoids miing up normal 'short' addresses with onsist addresses.

4 General Installation Proedure (see the lighting installation options on following pages before atually installing the deoder): emove the shell from your loomotive Cut the wires soldered to the eisting loomotive iruit board. Cut as lose as possible to the iruit board. Unlip the iruit board from the plasti motor mount bosses and disard. Install the deoder omponent side up with the narrow end toward the rear of the loomotive. If you want to use a white ED for the headlight see the setion on onneting the lights to see where to solder it before mounting the deoder. efer to the motor onnetion diagram below. Trim the loomotive wires to length as they are soldered to the deoder. Strip about 1/8" of the insulation off the end of eah wire and tin the end. (To "tin" a wire melt a little solder on the end to keep the individual strands wire together). There is already a small amount of solder applied to eah solder pad on the deoder. Just plae the tinned wire on its solder pad and touh your soldering iron to the tinned wire and pad to solder the wire in plae. eave about 1/4" slak in the motor leads and wires from the front truk. eave about 1/2-3/4" slak in the rear truk wires. Wath for shorts! Ensure the deoder is properly seated on the motor bosses TOP MOTO WIE (up thru hole in deoder) FONT TUCK EA TUCK FONT TUCK EA TUCK FONT OF OCOMOTIVE BOTTOM MOTO WIE (up thru hole in deoder) P2K-SW9 deoder motor onnetion diagram Now is a good time to test the loomotive before installing the lights and replaing the body shell. Double hek your wiring and make sure that there are no pinhed or broken wires. We see many deoders returned due to wires getting pinhed between the body shell and frame ausing shorts. Always test your deoder installation on a urrent limited programming trak before trying it on full trak power. If you have a Digitra, enz Set-02 or MC system that does not provide urrent limited programming use a 100 Ohm resistor in series with one of the trak leads and listen for the "lik" that verifies orret operation as you program the deoder. Test run the loomotive on your main line or test trak to verify that it runs orretly. After initial testing is omplete it's time to wire in the lights. Wiring the ights: Due to the high in-rush urrent of inandesent grain-of-wheat type bulbs (about 10 times the normal operating urrent) funtion outputs are rated at 40mA eah. We reommend Miniatronis part number (2.4mm diameter 14 volt/30ma) or number (1.7mm diameter 12 volt/30ma) bulbs for good results. ast revised: 20 Marh 2000 Page4

5 The P2K-SW9 deoder ships from the fatory with three usable funtion outputs, Headlight, earlight and an optional rotary (flashing) beaon ativated as. emove the front light and its assoiated brass tabs from inside the body shell. There are three options available for wiring the Headlight: - 12 or 14 volt bulb:wire a volt bulb to the holes indiated in the drawing below Solder short jumper wire between the holes marked with an "X" to onnet the funtion output to the Headlight bulb (or just solder the wire marked "H" to the lower "X" hole). - White ED: Solder white ED (part number CMD204UWC0ND from Digikey Eletronis DIGIKEY) to the solder pads at the fron of the deoder. The long lead (anode) od the ED solders to the top pad of the deoder. Be sure to insulate the lower lead with shrink tubing or line the groove in the loomotive weight with a strip of blak tape to keep the ED from shorting to the frame. There is already a 1K resistor installed on the deoder for the ED. - Use the eisting 1.5 volt bulb: This installation requires a 270 Ohm 1 Watt resistor required installed in one of leads of the eisting bulb. This resistor is physially large and may generate enough heat to melt the shell of the loomotive. There are two options for wiring the ear ight: - Use the eisting 1.5 volt bulb: emove the brass tabs from the inside of loo shell and from the rear light wires. Tin the end of the wires and solder them to the pads marked and * on the deoder. A 100 Ohm resistor is already mounted the the bottom of the deoder to limit the voltage at the bulb. This bulb is powered with "half wave" power and the resistor is sized to properly dissipate the heat when the deoder is operated at normal (12-16 volt) trak voltage or 14 volt bulb: Wire a volt bulb to the holes indiated in the drawing below for a volt rear light Optional rotary beaon: If your prototype has a rotary beaon you an add an additional 12 volt bulb onneted to Use a volt bulb if you wish to add a flashing beaon HEADIGHT VOT BUB H EXISTING 1.5 VOT BUB If you want to use a volt bulb for the rear light wire it to these holes EA IGHT To use an ED for the Headlight solder the long lead (anode) to the top of the deoder and the short lead (athode) to the bottom Put a short jumper wi re between the holes marked "X" if you use a volt headlight bulb the holes marked "C" and "". The beaon is ontrolled by. The funtion is designed to use an inandesent bulb. (Miniatronis sells red bulbs) If you use a red ED an appropriate series resistor will also be required. The effet may not be as good with an ED. ast revised: 20 Marh 2000 Page5

6 Wiring for non-diretional lighting: - Install a jumper wire as shown below for the headlight and the rear light to be on when the headlight is ativated. - Install a diode with the anode (unbanded end) toward the lower "X" hole if you want the head light to be on in both diretions of travel and the rear light to ome on only in reverse. Install this jumper wire if you want both front and rear lights to operate as one. JUMPE DIODE If you want the headlight on when you bak up but the rear light goes out when you go forward install a diode instead of the jumper wire with polarity as shown above This deoder is overed by our guarantee.
