Proto RS2 Decoder install? : LUSENET : Wiring for DCC : One Thread

Hi Just purchased an RS2 Proto 1000 and would like to install a decoder. Tried to install a NCE decoder and from the smell of things ""McDonalds French Fries"" I may have blown it...Has anyone installed a decoder in an RS unit,,,,Boo to Life-Like for not installing a 8 pin connector....I would of gladly paid the extra 1.47....Thanx in advance .

Did you verify that the motor leads are isolated from the power pick up leads? Assuming you got the red & black going to the pick-ups and the orange & gray going to the motor, not having the motor isolated from the pick-ups is the usual way to cook a decoder.

How did you make out with this install? I need to install a digitrax DH123P into a Proto rs2, any advice?

I just finished one on my LV RS-2. I installed a NCE D13SR and hardwired it to the existing LL board. The decoder sits in the cab area. You must cut through 3 traces on the board. One is under the board so it must be turned over to cut it.

Here is how the wires should be connected from the Central Hobbies site. Its for the C-liner but it works for the RS 2.

"Decoder installation is easy. On the circuit board cut the traces at the three "X"s and solder the decoder wires to the numbered pads. Here is the pin conections that are labled on the board. Solder it up and you shoud be good to go in about a half hour.

Pad one is for the Orange Wire Pad four is for the Black Wire Pad five is for the Gray Wire Pad six is for the White Wire Pad seven is for the Blue Wire Pad eight is for the Red Wire There are no solder pads for the rear headlight (Yellow wire, should be pad two) or function one (Green wire, should be pad three). The headlight will be too dim. I soldered a 300 ohm resistor in parallel with the one on the board to get enough brightness."
