Using track sensors
Track sensors are used to synchronize the location of your trains with the recording. Four
sensors can be used on your layout. Without the sensors, the ARC would not know where
your trains are. This would be a problem if you wanted to perform an action when the train
reached a certain spot (e.g., throwing switches, loading cars, etc.).
There are many options for creating track sensors. A track sensor simply does the job of a
switch, completing an electrical circuit that passes through the sensor terminals. While you may
create your own sensors using switches or optical devices, the simplest sensor is a special insu-
lated track section. Refer to the “Making a sensor” section on page 16.
Never have different recordings waiting on the same sensor at the same time.
General overview of using track sensors
1. Remove the jumper from the side of the ARC. Refer to Figure 3 on page 7.
2. Press ACC and enter the ID# of the recording. (Choose one of the eight recordings to work
with.)
When creating a recording, the STATUS LED blinks off that recording number.
3. Press AUX1, 9 on the numeric keypad to start recording.
4. Create the first part of your recording.
5. Press ACC and enter the ID# of the recording, then press AUX1 and enter the number (1-4)
of the sensor that you want to wait on. Keep in mind that Sensor #1 is connected to the
SENSOR 1 terminals; Sensor #2 is connected to the SENSOR 2 terminals; etc.
During playback, the recording will pause here until the train triggers that sensor or
you press AUX2.
6. Complete the first recording, then press AUX1, 0 on the numeric keypad to stop recording.
7. Replace the jumper.
When you play back the recording, the first portion will play through. The recording will
pause where you inserted the sensor command. When the train activates the sensor, the record-
ing will continue. If you want the recording to continue without waiting for the train, press
ACC, enter the ID#, then AUX2 on the CAB-1 Remote Controller. AUX2 will force the recording
to continue.
Always keep the starting points, speeds, voltages, and positions the same. Before playing
the recording, be sure to position the locomotives and accessories where they were
when you started to record. To help, have the recording start by waiting on a sensor.
When the recording is waiting on a sensor or paused during playback, the STATUS LED
will blink the sensor number. For example, if the recording is waiting on sensor #2, the
LED will blink twice. At this time, the COM LED will illuminate without blinking.
