3. Decoder*:
Item #340 - Atlas offers an HO scale multi-function Dual-
Mode Decoder™ that, once installed, allows you to easily switch the
operation of your locomotive from analog to digital mode. This function
enables you to run your decoder-equipped engines on an analog layout
without the typical speed differential. N scale multi-function decoders are
also available. Some HO & N scale Atlas locomotives have decoders
factory-installed, for your convenience. See our web site for further
details. www.atlasrr.com

The Atlas Master DCC System components conform to the NMRA DCC
standards and are also compatible with items from other DCC manufacturers.
GETTING STARTED
In order to function, the HandCommand must be connected to a Commander or
other command station that supports XpressNET technology (see shaded box on
right for definition of XpressNET). This connection can be made directly using the
7' XpressNet cable (see instructions below) or through an installed Universal
Panel Connector (UPC; see separate usage instructions enclosed), using the 6'
coiled cord. Using the UPC gives you the ability to use your HandCommand from
a location that is remote from your Commander.
Connecting the HandCommand to the Atlas Commander (or other
Command Station)
The Atlas HandCommand is designed to work with the Atlas Commander or any
system that supports XpressNET technology. You must have an Atlas Commander
or other Command Station to use the HandCommand; it cannot function inde-
pendently.

Connecting the HandCommand to a Commander
The HandCommand connects to the Atlas Commander via the XpressNET con-
nector on the back of the Commander. The connection is made with a 6-con-
ductor wire having a six-pin RJ25 connector; a 7’ wire is enclosed. Up to five
HandCommand throttles may be connected to one Atlas Commander. See UPC
instructions for diagram.
XpressNET is a high-speed digital network based upon the industry standard
RS-485 protocol. The Atlas Commander uses XpressNET to communicate
between its high-speed components, such as the HandCommand. XpressNET
communicates at 62.5 thousand bits per second (nearly 4 times faster than its
closest competitor). It is the highest performance network in widespread DCC
use and all its protocols are freely available to both the industry and the hob-
byist.
XpressNET is an industrial based technology, which can be setup in an infinite
number of possibilities, making it simple to setup and control any layout, large
or small.
See separate instructions for installing and using the Atlas Universal Panel
Connector.
