7.6 TRACk STATUS Indicator
The
TRACK STATUS
indicator shows that there is voltage on
RAIL A
and
RAIL
B
terminals. The color indicates the type of signal.
• orange
indicates the track is getting signals with no analog zero
stretching.
• green or red
indicates a “stretched zero” signal is being used to
operate a conventional (analog) locomotive. When zero stretch-
ing is present, the decoder equipped locomotives will read their
digital commands normally and perform as commanded.
• not lit
indicates there is no voltage on the track, the track power
to the DCS100 may be OFF.
7.7 LOCONeT jacks A and B
These jacks let you expand your Digitrax system by simply plugging LocoNet
devices in to the system. They can be used for throttles and other LocoNet
devices. These jacks are functionally the same and can be used interchange-
ably.
7.8 SCALe Switch (O/G, N, HO)
This switch sets the maximum track voltage limit.
7.8.1 Track Voltage Adjustment
The actual track voltage supplied by the DCS100 can be adjusted. To do this,
you must open the DCS100 case (this will not void your warranty).
1. Remove the DCS100 input power and disconnect all DCS100 leads.
Remove the gray plug from the front of the DCS100
2. Remove the two screws on the top and bottom of each side of the case.
3. Slide the gray front panel off the DCS100.
4. Be careful to avoid disturbing components other than the ones described in
the following steps.
5. Locate the small trimmer potentiometer behind the
LocoNet Jack B
and
Scale Switch
.
6. Use a small screwdriver to turn the potentiometer clockwise to increase the
scale voltage setting. Turn it counter clockwise to decrease the voltage set-
ting.
7. To determine the actual track voltage, measure the DC voltage (unloaded)
Scale
Max Track Voltage
O/G
20 volts
N
12 volts
HO
15 volts
