To the right is an illustration of the CAB04 Intermediate Cab. Following is a
description of the various controls and indicators of the cab.
STATUS LED
To the left of the speed control knob is the
cab status LED. It will briefly flash whenever
a key is pressed or will glow continuously to
indicate when data entry is required.
SPEED KNOB
This knob controls the speed of the
locomotive. With the CAB04p the knob turns
a
potentiometer
inside the plastic case. If the
cab is set to "yard" mode the knob is "center
off'', turning it to the left goes faster in
reverse, turning it
to
the right goes faster in
forward.
DIRECTION KEYS
Pressing the FWD key will cause the Loco to
move in a forward direction. The REV key will
cause the Loco to move in a reverse
direction. These buttons are disabled when
the cab is in "yard" mode (use the knob to
change direction).
OPTION KEY
HORN
This button comes factory set to act as a
direction toggle. Each push of this button will change the direction of the locomotive.
This button can be setup to act as any button you wish (see SETIING UP YOUR
CAB).
The OPTION button can also be set as a "Special" shift (we call it "sticky'' shift)
button. This will give
all the other
buttons on the cab an alternate use (see page 6).
This button is factory set to operate Function 2 which is the de-facto standard for the
horn/whistle feature of DCC sound systems . Unlike other keys which toggle functions
on and off this key is momentary, activating the function only as long as the button is
held down. If you want Function 2 to toggle on and off use the "2" button.
NUMBER KEYS
The keys O through 9 serve two purposes. First, when operating a locomotive if a
number key is pressed it toggles the corresponding function on the loco (if that
function is connected and supported by the locomotive decoder). The second
purpose is for entering numeric data that is required for selecting a locomotive or
other device. Use the O key for Headlight and the 1 key for Bell if you have a sound
system.

Setting the alternate button values:
I) Turn on the DCC system
2) Unplug your cab from the Cab Bus
3)
Press and hold down the SELECT LOCO button while plugging in the cab. The
cab will now enter its internal setup program. This is indicated by a flashing
LED on the cab.
4)
5)
6)
Press "6" to enter shifted key setup mode.
Notice the flashing of the LED slows to
indicate it's ready to accept a button number
to program.
Enter the
button number
followed by
.
ENTER (see diagram of button numbers on
the right) Only button numbers O through 21
will be accepted. If you get an error press
SEL LOCO to clear the error and reenter the
correct number. Notice the LED flash
changes pace when you press ENTER
indicating the cab is now waiting for a value
for the button.
Enter the new
button value
(from the
OPTION button table on the previous page)
followed by the ENTER key. Only button
values of O and 64 through 128 are
accepted. Other values will cause an error.
If you get an error press SELECT LOCO to
clear the error and reenter the correct value.
You can cancel the process at any time by
unplugging the cab.
7) To set the alternate values for other buttons
repeat this process from step 2

Another method to activate the alternate button values.
Inside the cab at the top of the printed circuit board are two holes marked SHIFT
(not the 2 solder pads marked SHIFT 2). If a momentary contact pushbutton is
connected to these holes it will act like the shift key on a computer keyboard. While
the new "shift" button is held down any key pressed will use its alternate value.
Connection of a pushbutton to these holes will not void the cab warranty
provided
the installation is performed in
a
competent manner.
We installed a Radio Shack part number 275-1571 pushbutton on the right hand
side of the cab about 5/8 inch (16 mm) from the top of the cab. See the installation
photo on the next page. The photo shows installation in a Cab04pr (radio equipped)
but should work just fine in a non-radio version.
