To Join Your Throttle to the layout Duplex Group

Connect a DT602D or other Duplex enabled Throttle, with a known good

installed batteries, to a LocoNet RJ12 jack on the layout with one or more

working UR93/UR92's.

The throttle will initialize, and log on to the network, automatically detect

layout Duplex support exists and obtain the Duplex Net/Group Name, Chan-

nel and Key number.

When this throttle disconnects it will change to Duplex wireless radio opera-

tions and perform most tasks as if it were plugged in to the LocoNet system.

Use the e.g. DT602D throttle to select one of the locomotives on your system.

The UR93's GREEN ID LED will wink OFF about 1 sec to show that good

duplex messages are being received. When there is no Duplex traffic the ID

will do a short wink OFF very about 2 seconds to indicate it has an active

Duplex beacon supporting Duplex throttle with the correct Group Name and

settings.

If the Duplex RF messages are not acknowledged by the UR93, the e.g.

DT602D will blink its white "flashlight" LED to show there is a duplex

communication problem. This usually indicates a range or interference issue.

(See troubleshooting section.)

DT602Ds and other Duplex throttles remember the last joined Duplex

Group, even if the batteries are removed, so when re-powered they will au-

tomatically wirelessly rejoin this particular Group if it is within Duplex radio

range.

This 'tethered' LocoNet method of joining the UR93 or layout Duplex Group

will always work to join any Duplex throttle to a particular Duplex Group. This

method bypasses the need to know the Key number if it is not 0000, and active.

Alternatively, you can also join in wireless mode! See the DT602 manual for

instructions on; joining a Group without plugging in, and changing Duplex

settings.

Troubleshooting Your Installation

To get the best performance out of your initial duplex radio installation, walk

around the layout and verify Duplex operation, to check you have adequate signal

coverage and reliability.

If the Duplex link has a connection problem, when you e.g. change speed on an

active throttle the white LED will flash. Note that throttle orientation and body

position of you and your operators may also affect the UR93's range and recep-

tion.

Depending on the layout size, geometry and surrounding materials it is often

possible to move the UR93(s) to better cover possible dead spots. Experimenting

with UR93 location will usually help you locate a position that is best for your

layout and allow reliable operations.

On larger layouts, or layouts with problem areas, it is simple to add more

than one UR93. Adding extra units will automatically provide space-diversity

coverage overlap and signal reliability.

Other devices such as Microwave ovens, 2.4GHz Wifi Cameras and Wifi Rout-

ers may cause interference on one or more of the Duplex channels 11 to 25. Try

changing channels with the DigiGroup PC app or a throttle.
