3.1 Power (PWR) Indicator
This LED indicates there is power
supplied to the . It
will light either green (command
station mode) or red (booster
mode). The PWR indicator will
light GREEN or RED winking off
every 3 seconds as a “Heartbeat”
when the unit is in RUN mode.
See Section 3.17 for full light
(LED) indication list.
3.2 DC Power In 2mm Jack (5A) or screw Terminals (“+” and “-“ 8A)
The may be powered either using the 2mm jack or the screw terminals
labeled 8A “+” and “-“. The 2mm center positive jack is rated for a maximum of 5
amps. The screw terminals can be used with any suitable power supply up to the unit’s
maximum 8 amps.
The sets the current limit based on the active DC input
.
Make sure your DC power supply is rated for your desired voltage and amperage.
When using the screw terminals make sure that the polarity of the DC supply matches
the correct terminals on the connector. The is reverse input protected, but it
will not power on if the DC polarity is incorrect.
Never power with AC voltage.
The is for use with DC voltage input ONLY, MAXIMUM INPUT is 8
AMPS, 24VDC, 192 VA MAXIMUM CONTINUOUS, DO NOT Exceed 25VDC Input.
Minimum Input 13.8 VDC.
It is recommended that when selecting a DC power supply the voltage should slightly
exceed by about 1V the track voltage you plan to run your layout at. However, the DC
input voltage should not exceed track voltage by more than 3V. If the DC supply volt-
age exceeds track voltage by more than approximately 3V the will enter Safe
Operation Mode and may limit its current capacity.
3.3 Program A and B terminals (PA and PB)
The PA and PB terminals are the output for the second set of command signals for the
programming track that can be used while the rest of the layout continues to run. These
outputs are used for both programming via USB or by programming using a throttle.
When programming using USB and Digitrax SoundLoader or other software, the pro-
gram track will not be available for throttle programming. You will receive a “fail”
message on your throttle if you try to program in Service Mode. Operations mode pro-
gramming is unaffected by USB programming.
3.4 Program (PROG) Indicator
The PROG indicator will blink red when the program track is active. This light will
flash constantly when using the with SoundLoader.
3.5 Ground (GR) Terminal
The center terminal marked GR provides electrical safety features and an RF ground
reference for minimum radiated noise. This should be the ONLY point of any
installation that is connected to the AC safety ground pin provided on most 3 pin 110V
AC power sockets. Grounding the system is a sensible safety precaution that should not
