MRC AD322 Quick Start Manual

2. MRC Light Effects:

A. "Rule 17" directional headlights: Headlights on/off, (F0), light button. One
light is bright to indicate direction of travel and the other is dim. Also in
this mode, the (F0) light button turns on the strobe light if hooked up.
Normal headlight wiring is used for "Rule 17" lighting (white, yellow & blue
common wire).
B. Ditch lights: Use of the long horn (F2) or short horn (F3) buttons will
activate ditch lights with horn sounds. Ditch lights will flash 5 times after
horn sound ceases. If your DCC system has an F5 button, you can use it
to turn ditch lights steady on/off. Otherwise you must use the uncoupling
button (F4) to turn ditch lights steady on/off. When horn is activated, the
ditch lights will flash. To wire ditch lights, use green and purple accessory
wires with blue (headlight) common wire.
C. Strobe light: This light simulates the rooftop strobe light on some
locomotives. In the MRC Light Effects mode, the strobe will flash when
"Rule 17" headlights are on regardless of loco direction. To wire strobe
light, use brown accessory wire with blue (headlight) common wire.
When hooking up accessory lighting, regardless of mode being used,
use light bulbs rated at maximum track power. The bulbs receive full
track power when the functions are activated. Auxiliary factory
installed locomotive lighting that use LEDs or 1.5-volt bulbs will need
a resistor placed in line to prevent them from burning out.

HOW TO SELECT THE MRC LIGHT EFFECTS

The AD322 is shipped from the factory in the normal/default mode (address #3)
normal lights & functions. There are two ways to access the MRC Light Effects:
1. The MRC EZ way (for all DCC systems except the MRC Command 2000):
Place your locomotive on a programming track. Program your locomotive to
address #1. This step turns our MRC Light Effects on. Final step: Now
program in your locomotive running address, either 2 or 4 digit, and adjust
the rest of your running parameters (momentum, start voltage, etc). That's
it! To turn off the MRC Light Effects, simply program the locomotive to
address #3 and then follow the final step above.
You cannot run a locomotive on address #1 and retain normal lights/
function or run a locomotive on address #3 with MRC Light Effects.
These two addresses are reserved for turning the functions on and off,
but a locomotive will still be able to run on these addresses.
2. The other way:
If your non-MRC DCC system has the ability to program CVs, you can go
directly to CV 64 to turn on your MRC Light Effects. You can use the
register/ CV chart we have provided for you in this instruction booklet or visit
the National Model Railroad Association website at www.nmra.org for a
more comprehensive understanding of CVs and registers.

PROGRAMMING

The AD322 decoder supports the following register and CV programming.
MRC PRODIGY DCC and MRC Command 2000 users do not need to
know all these register/CV numbers because the MRC DCC systems use
model railroading terminology. It is easy to understand and easy to
program.
CV Register Description
CV1 R1 Short address
CV2 R2 Start voltage
CV3 R3 Acceleration
CV4 R4 Deceleration
CV5 --- Max voltage
CV29 R5 Basic configuration
CV7 R7 Manufacturer version number
CV8 R8 Manufacturer ID
CV17 --- Long address upper byte
CV18 --- Long address lower byte
CV19 --- Advanced consist address
Light effect setting
CV64 ---
(0=special light effect/1=normal light effect)
CV105 --- User identifier number
CV106 --- User identifier number
--- R6 Page number
The MRC AD322 decoder should perform well when used with other brand
command systems. See your DCC command station's manual to learn how to
program and operate the decoder. For more information about register/CVs and
their functions, please refer to the NMRA DCC Standard & Recommended prac-
tices, RP-9.2.2 This is available directly from the NMRA or their website at
www.nmra.org.
