Typical Installations with Common Control Systems

For typical installations with common control systems, see Figures 4 through 6 starting
on page 16.

Selecting Configuration Options

The Rear ILS has three configuration options that are selectable with DIP switches on
the light bar control board. Table 2 describes the options.

DIP Switch
Position
1 Sets the directional arrow pattern for internal SignalMaster
head pattern. For the six-head pattern, move DIP Switch 1 to ON (Figure 1 on page 11).
2 Not used
3 Switch 3 has three functions:
• Activating a lower or upper rear mounted ILS
• Performing an LED scan to ensure that an LED board flashes the correct colors after it is
installed.
• Changing the Device ID to enable the SpectraLux
light bar (available with the Convergence Configuration Software).
Choosing to Activate an Upper or Lower Rear ILS
To activate an upper rear mounted ILS, set Switch 3 ON.
To activate a lower rear mounted ILS, set Switch 3 OFF.
Performing an LED Scan
When an LED board is changed, an LED scan must be done to enable the LED board to flash the
correct colors.
To perform the scan:
1. Disconnect the red power (BAT+) wire to the SpectraLux ILS and maintain power to the
control head/interface box.
2. Change the position of DIP Switch 3 and turn power ON to the SpectraLux ILS. The
SpectraLux ILS emits a short flash to indicate the LED scan is done.
3. To return DIP Switch 3 to its original function, repeat the scan.
Changing the Device ID
The default setting for the SpectraLux ILS is to respond to light bar commands. For example, if the
system includes a light bar and a SpectraLux ILS, both devices perform the same functions. The
Convergence Configuration programming software enables you to program the control head to
send a set of commands dedicated only to the SpectraLux ILS, making its operation independent
of the light bar.
To reset the control head to the default setting, perform an LED scan as described above.
4 Sets the ability to power the network cable for other devices. The default is OFF. Switch 4 should
only be set if the main power cables are turned on through an ignition-activated relay. If powering
other devices, such as the Six-Button Serial Controller, set DIP Switch 4 to ON. For more
information, see the instructions included with the network-powered device.
