Mast Base can also be used with conventional mast mounts as a to make them
plug and play.
Warning: Current setting resistors with a minimum value of 100 ohms must
be used with all LEDs operated with your SE8C. These resistors are incorpo-
rated into the Digitrax Plug ‘N Play Signal Mast Base board. If you do not
use this board, you must add your own resistors to prevent damage to the
board.
Customizing the Signal Masts
You can use the Digitrax Signal Mast Base for connecting any signal mast in
any scale you want to use to the Signal Driver Cable.
1. Cut the Digitrax Signal Mast off the Plug ‘N Play Signal Mast Base.
2. Set the angle and height for the new mast and solder it to
the large pad provided on the back of the Signal Mast
Base. (See figure next page). Or use the 4 holes in the
board for a pair of retaining wires to hold the signal mast
in place. Be sure to insulate the Signal Mast Base from
the signal you are attaching if there is any chance that it
might touch the traces on the circuit board and cause a
short circuit!
3. The Plug ‘N Play Signal Mast Base provides the resistors
required for connecting the LEDs on the signal mast.
Solder the wires from your signal mast directly to the
associated pads on the Signal Mast Base as indicated in
the following schematics and photos.
For clarity, the following examples use a line name for each
Signal Mast Base solder pad to avoid confusion with
wire colors. In the first example, 3/3 Signal heads with
green, yellow and red LEDs, the line names correspond
to the LED colors. One Signal Mast Base must be used
for the A1/A2 signal heads (A Orientation) and one for
the B and C signal heads (B/C Orientation). See figure
Sample Layout Security Element (Plant)--for a typical
signal location.
