DIP Switch Programming Procedure
User configurable parameters can be programmed using the 3-position DIP switch, on-board push-button switch,
and on-board LED.
Enter Programming Mode
DIP programming mode can only be accessed at power-up, prior to linking the Tx/Rx. With RailBoss power on,
and the Transmitter off, momentarily press the yellow push-button located next to the DIP switch. The LED will
begin flashing.
Select Parameter
Select the parameter you wish to view or program using the DIP switch. (the white square indicates position of the
switch; e.g. for parameter 0, all switches are in the down or off position.
View Current Option Code
The LED will repeatedly flash the option code for the currently selected parameter; e.g. two flashes followed by a
pause indicate option 2.
Change the Option Code
Momentarily press the push-button during the pause to advance the option to the next higher number, until you
get the desired number of flashes.
Save the Option Code
Press and hold down the push-button for about 4 seconds until the LED starts flashing rapidly, which indicates the
save is complete.
Select the next Parameter
Repeat the above as needed to view or make changes to other parameters. Note: If an invalid parameter number
is selected, the LED will stop flashing.
Exit Programming Mode
Turn off RailBoss power.
Upon return to power, the new options will be activated.
The DIP switch sets a binary number. Each switch, when turned on, has a different value. When added together,
they give you the parameter number.
But don’t worry! All you need to do is look at the pictures on the next
page, and set the switch accordingly.
Switch position 1 has a value of
1
Switch position 2 has a value of
2
Switch position 3 has a value of
4
The switch setting shown here is set for parameter 6:
Switch 1 = 0 (off)
Switch 2 = 2 (on)
Switch 3 = 4 (on)
for a total of 0 + 2 + 4 = 6
