Overview -
The Control Point Module serves as the ‘brains’ of the
Whelen WC Series lightbar. The module is programmed with
the WeCan™ Programming Software via the USB port and in
turn, provides the necessary signals that allow the lightbar to
function in the desired manner.
As represented in the WeCan™ Programming software, each
of the 18 inputs may be programmed to activate any number
or combination of the installed lightbar components. This is
accomplished by applying +12VDC to an input. Refer to the
sample wiring diagrams shown on pgs. 2 through 4, or the
installation guide included with your switches for detailed
wiring information.
Note - The pattern override feature will override all active
LED lightheads with the pattern override flash pattern.
Programming Procedure -
IMPORTANT - It is not necessary to program this device
unless
changes to the default configuration (for example
pattern or switch control changes) are desired.
1. Connect a USB cable from the host PC to the module’s
USB port.
2. Start the WeCan software on the host PC and open the
configuration to be programmed.
3. Click on the “WeCan” button on the menu bar. Select
“Control Point” then “Program” from the fly-out.
4. A window will open to confirm that you are about to
program a Control Point Module. Confirm that the USB
cable is connected to both the module and the PC and
then press “OK” to continue. The software will display a
window when the programming procedure has been
successfully completed.
5. Confirm proper operation of the module.
