Layout Control System
Frequently Asked Questions
Q1: How do you program the switch machine?
A1: You don’t have to – it’s ready to go on arrival, but for DCC use you can assign a unique address. The complete instruction and user
guide will be available on Walthers.com shortly, linked as a PDF on the SKU page for the Switch Machine. Therein you’ll find all the
details needed to program a DCC address.
Q2: Does the switch machine include a built-in decoder?
A2: Yes, a DCC accessory decoder is integrated into each Switch Machine. Any standard accessory decoder address may be used to
control the Switch Machine.
Q3: Do you have to use the Walthers Distribution Block to control the Switch Machine?
A3: The Distribution Block is essentially a terminal strip/connection between the power supply and up to eight switch machines. The
Distribution Block is not necessary if you are controlling only one Switch Machine and are plugged into an alternate power source
via the servo connections.
Q4: Does the Switch Machine require use of the Fascia Controllers?
A4: No, the Walthers Fascia Controllers and accompanying indicators are designed to seamlessly integrate with the Switch Machine in
an easy plug-and-play manner, but are not required. The user may use their own push-button controller or toggle switch for control.
Complete details on control connections are included in the instruction manual and user guide.
Q5: Is this system compatible with similar types of servo-based switch machines and/or accessories?
A5: No - our system is designed for simpler installation with no programming or component assembly needed; some other systems are
also designed for use with specific track products.
Q6: Can the Walthers Layout Control System be powered from any power source?
A6: We recommend powering your switch machine with Walthers 2 Amp 12V Filtered DC Power Supply (#942-110, sold separately).
You can also connect to a standard DCC booster output and use accessory decoder commands, electrical switches or other digital
inputs. If you use any other type of power supply, be sure it provides 12-18V of filtered DC before installation.
Q7: Does a DCC bus control the power?
A7: A DCC track bus is not recommended and may cause a system shut down if used. You may connect the Switch Machine to a
standard DCC booster output.
