Introduction
Thank you or purchasing this Ring Engineering product. We take pride in the
products that we produce and hope you ind this product to be a great addition to
your model railroad layout.
Please read all warnings and instructions be ore installation and use. For the
latest in ormation including the latest revision o this manual please visit our
Internet site at www.RingEngineering.com.
The AM-1 is an Accessory Module that you can add to your model railroad layout
to control accessories like Turntables, Swing Bridges, Oil Pumps, Control lights
in buildings / houses etc. You can add sounds and actions to things like arms
and passenger stations and much more! You can use the AM-1S to control
motors, lights, and play sounds by using a RailPro controller such as the HC-2
handheld controller with color touch screen. You can use the Ring Engineering
RailPro Assistant So tware to load projects Ring Engineering provides or even
build custom Projects or your AM-1S! You can add your own picture and include
custom logic to add some intelligence to your projects too!

Warnings
Direct Radio
This product is equipped with Direct Radio. Direct Radio is a custom designed
RF transceiver to allow this product to have high-speed, two-way communication
that is very easy to setup and use.
Installation
Ste 1 – Mount your AM-1S
Position the AM-1S near the products that you plan to wire to the AM-1S under
your layout. Use at least 2 screws and mount the AM-1S. I only using two
screws, be sure the screws are located in opposite corners. The red arrows in
igure 1 below identi y mounting holes.

WARNING: Only connect a Ring Engineering approved power supply to the proper
power input connections. Maximum voltage is 16 Volts DC. A power supply with
excessive voltage or improper voltage can cause a ire. Never connect AC power
supplies to the AM-1.
WARNING: Connecting improper electrical devices to the AM-1S (such as devices
with to low o a voltage, current, or power rating) may case a ire.
The output or motors is high requency pulse width modulation to control speed.
WARNING: Some motors can overheat and may become a ire hazard. Be sure the
motor you connect to the module is sa e or pulse width modulation speed control.
WARNING: This product can expose you to chemicals including lead, which is known
to the State o Cali ornia to cause cancer and birth de ects or other reproductive
harm. For more in ormation go to www.P65Warnings.ca.gov.
WARNING: Operate and store in dry environment only.
Relative Humidity: Operating 20% to 90% non-condensing, Storage 10% to 95% non-
condensing
WARNING: This product is not recommended or persons under ourteen (14) years
o age.
WARNING: There are no user serviceable parts inside. Return to Ring Engineering
or repair.
WARNING: Temperature: Operating 32F to 80F, Storage 0F - 110F

Ste 2 – Connect the Power
Be sure the power supply you are going to connect to the AM-1S is turned o .
Then connect power supply to the “Power In” terminals labeled ‘P1’ and ‘P2’ with
16-gauge wire.
Only connect a Ring Engineering approved power supply to the
proper power input connections such as the PWR-56. aximum voltage is
16 Volts DC. A power supply with excessive voltage or improper voltage
can cause a fire.
NOTE: The AM-1S is not polarity sensitive. You can connect either power supply
wire to the ‘P1’ or ‘P2’ connectors.
The AM-1S is equipped with spring-loaded terminals or ast and secure
connections that do not require a tool. To connect a wire to the terminals, irst
strip 3/8 o an inch (about 2/3 the length o the terminal block) o insulation o the
wire. Then press the orange push button over the contact that you want to
connect a wire to. Insert the wire into the round hole under the orange push
button. Be sure the wire goes all the way to the back o the terminal block while
holding down on the orange push button. When you eel the wire touch the back
Ring Engineering Inc 4

o the terminal block, release the orange button to secure the wire into the
terminal block. Give the wire a tug to be sure it is securely connected.

Ste 3 – “Find Product” on your Controlling Device
Power up the AM-1S and press the “Find Product” button on your controlling
device such as the HC-2 handheld controller. I you look in the Accessories
Page you will see a new picture o a AM-1S.
Ste 4 – Load a Project File to the AM-1S
Use the RailPro Assistant So tware to either load an existing project (like a
Turntable project) or create a new custom project or the AM-1S. Follow the
directions in the RailPro Assistant So tware User Manual to create and load a
project to the AM-1S.
Ste 5 – Connect the Electronics to be controlled
Be sure the power is turned off before connecting or disconnecting
any wires to the A -1S.
After the electronics are connected your AM-1S is ready to use!

Minimum #30
Maximum #16

Wire a S eaker
Switch Terminals
Speaker 1 S1
Speaker 2 S2
IMPORTANT: Speaker can be rom 4 to 16 ohms. AM-1S can drive up
to 1.2 Watts o power into a 8 ohm speaker. The AM-1S will drive up to
2.0 Watts o power into a 4 ohm speaker.
TIP: You can parallel two 8 ohm speakers to provide a 4 ohm load the
AM-1S.

Wire LEDs
(Only 'Light 1' connection shown)
You can connect up to 8 lights to the sourcing outputs on the AM-1S.
Connection terminals or all lights to the sourcing outputs.
Switch Terminals
Light 1 O1
Light 2 O2
Light 3 O3
Light 4 O4
Light 5 O5
Light 6 O6
Light 7 O7
Light 8 O8
Using LED’s without resistors can damage the LED’s! Use 1k Ohm
1/4 W for 15mA or 750 Ohm 1/2W for 20mA.
If you use the wrong resistor, it is possible to generate enough heat to
ignite flammable material, and cause a fire.
IMPORTANT: The sourcing outputs o the AM-1S (O1 - O8) output 14 volts and
the return must be wired to the C1 (common) connection.
IMPORTANT: The maximum allowed current or outputs O1 - O8 is 400mA per
point continuous and 400mA continuous or all points combined. Some
acceptable examples would include: 1) Two 200mA loads run at the same time
or 2) Four 400mA loads but only one run at a time.
IMPORTANT: Since O1 - O8 are sourcing outputs, the positive side o the LED
must be connected toward the output terminal and not toward the common
terminal. I a LED is wired backward it will not light up.

width modulation.
IMPORTANT: The motor should have stall currents o 1 Amp or less. The
maximum allowed current or outputs O1-O8 is 400mA per point continuous and
400mA continuous or all points combined. Some acceptable examples would
include: 1) Two 200mA motors run at the same time or 2) Four 400mA motors
but only one run at a time.
