CONNECTING YOUR ACCESSORY DECODER TO A SLOW MOTION POINT MOTOR (DC)
(DIAGRAM 3) or SIGNAL LED’s (DC) (DIAGRAM 4)
Your accessory decoder rectifies the AC input so an auxiliary DC power supply is not needed, just an AC power sup-
ply can be used for DC accessories. Follow Diagram 3 for each pair of the 4 outputs (A-B-C-D).
Ten 300 ohm resistors are included with the decoder for use with slow motion point motors or signal LED’s.
Use resistors to connect signal LED’s (not included) to the four pairs of outputs (A-B-C-D) of your accessory

(A-B-C-D) (DIAGRAM 5)
PROGRAMMING THE DECODER
This decoder has the following CV’s
CV513 - main address that is a 2 digit (1-127) address
CV515 - The output mode of Pair A (sub-decoder A)
CV516 - The output mode of Pair B (sub-decoder B)
CV517 - The output mode of Pair C (sub-decoder C)
CV518 - The output mode of Pair D (sub-decoder D)
If your DCC system cannot program CV513 to CV518, you can use CV1 to CV6 to program the decoder on the
Program Track. The CV mapping is as follows
CV1 = CV513 = main address
CV3 = CV515 = pair A output mode
CV4 = CV516 = pair B output mode
CV5 = CV517 = pair C output mode
CV6 = CV518 = pair D output mode
PROGRAMMING
During the programming mode, you cannot program reverse polarity into the accessory decoder. You can only re-
verse the polarity of a specific output when you program a route for your accessory decoders on your DCC system
PROGRAMMING ADDRESS CV513
The main address can only be programmed on the Program Track. This main address, once programmed, automati-
cally assigns the four outputs their sub-addresses, so you need only to program one address to the decoder. Your
decoder’s main address is pre-programmed to #1 at the factory. So the sub-addresses are 1,2,3 and 4..
If you have a second decoder, you can use the CV program mode to program its main address CV513 to #5. So the
second decoder’s sub-addresses will be 5, 6, 7 and 8. If you have a third decoder, you can program its main address
CV513 to #9. So the third decoder’s sub-addresses will be 9, 10, 11 and 12. Always program the main address to
1, 5, 9, 13, 17, 21…
PROGRAMMING OUTPUT MODE CV515, CV516, CV517 and CV518
Each pair of the outputs can be set to 3 different types of output mode as follows
1. Steady ON, or steady OFF, (Latching) for slow motion, point motors or lights in buildings
2. Momentary ON/OFF for twin coil type point motors
3. Alternating flashing (with variable flash rates) such as those at level crossings.
A simple combination of diagram 3 and 4,
Example 1:
To set pair A outputs to control a slow motion point motor (latching) or to turn lights in buildings ON or OFF, program
CV515 to a value of either 0 or 128. CV515 is for Pair A
Example 2:
To set pair B output to control a twin coil point motor momentarily, program CV516 a value from 1 to 127, with 1 as
the minimum turn-on time (0.1 second) and 127 as the maximum turn-on time (12.7 seconds). Here CV516 is for
pair B. The amount of time the output is ON is equal to 0.1 times the number you program into the CV, but it will
work for the other 3 outputs as well.
Example 3:
To set pair C outputs to alternating flash for a pair of level crossing lights, program CV517 to a value between 129 to
255. The flash rate is equal to 0.1 x (N –128), where N is the value programmed into CV517. For example, when
N=129, the flash rate is 0.1 second [0.1x(129-128)]. When N=133, the flash rate is 0.5 seconds [0.1x(133-128)].
