Intermediate Cab
Operations Manual
For
Cab version 3.1
Copyright 1994-2006 NCE Corporation
Last revised: 10. September 2007 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
Toward the top of the Cab, between the
speed control buttons, is a 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. If you have a CAB04e it turns a
digital encoder inside the plastic case. If you
have a 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
This button comes factory set up 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 SETTING UP YOUR CAB).
This 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.
HORN
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 0 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 be the decoder). The second purpose is for
entering numeric data that is required for selecting a locomotive or other device.
Use the 0 key for Headlight and the 1 key for Bell if you have a sound system.

Cab04p HEADLIGHT
The 0 button (the headlight is Function 0) toggles the Headlight on and off.
ENTER

Used to confirm numeric input.
SELECT LOCO
This selects the locomotive/consist to operate. When this key is pressed, the Status
LED will light indicating that a numeric entry is expected. Enter the loco/consist
number, then press ENTER.
MACRO
Macros are explained in detail in our system reference manual. When this key is
pressed, the Status LED will light indicating that a numeric entry is expected. Enter
the macro number, then press ENTER. Macros are used to control one or more
accessory decoders with a single command. In operation this is much easier than
using the Select Accy button to control switches.
SETTING UP YOUR CAB04
Just as every locomotive has a separate number (address in DCC terms) each cab
needs a separate address so the command station can distinguish one cab from
another. Each CAB04 is shipped from the factory with the address of 5. If this is
not your first CAB04 you will have to change the address before using the cab.
NOTE: Cab Address 49 is not a valid address. Use Cab addresses 19-48
for the Cab04p.
To change the cab address:
1)
Turn on the DCC system.
2)
Unplug your Cab04 from the cab bus
3)
Plug the cab back in while holding down the SELECT LOCO button.
4)
Release the SELECT LOCO button. The cab will now enter its internal setup
program indicated by a flashing LED.
5)
Press 1 to enter cab address setup mode. The LED flash rate slows to indicate
the cab is ready for you to enter a new cab address.
6)
Type in the desired cab address (always use 2 digits... Address 3 = 03) followed
by the ENTER key.
7)
If you enter cab address 00 the cab will reset to its factory settings. If you enter
address 01 the cab will revert to its original factory settings except for any shifted
keys you have already programmed into the cab. Valid cab addresses are 2 to
63. If you enter a number outside this range the LED will flash rapidly indicating
an error. Press SELECT LOCO to clear the error and go back to step 2. This
finishes setting the cab address.

Cab04p

To change between REGULAR and YARD modes:
1)
Turn on the DCC system.
2)
Unplug your Cab04 from the cab bus
3)
Plug the cab back in while holding down the SELECT LOCO button.
4)
Release the SELECT LOCO button. The cab will now enter its internal setup
program indicated by a flashing LED.
5)
Press 2 to enter Yard or normal select mode. The LED flash rate slows to
indicate the cab is ready for you to select which mode
6)
Press 1 for Yard mode or press 2 for Normal mode. If you enter a number
outside this range it will not be accepted and the cab will continue to wait for 1
or 2.
To change BALLISTIC TRACKING rate (CAB04e only):
1)
Turn on the DCC system.
2)
Unplug your Cab04 from the cab bus
3)
Plug the cab back in while holding down the SELECT LOCO button.
4)
Release the SELECT LOCO button. The cab will now enter its internal setup
program indicated by a flashing LED.
5)
Press 3 to enter the ballistic tracking rate setup mode. Notice the flashing of
the LED slows to indicating it is ready to accept the new data.
6)
Ballistic tracking provides a means the speed will ramp up/down quickly if the
knob is turned fast and it will ramp up/down slowly if the knob is turned slowly.
This gives you very fine control by turning the knob slowly yet allows quickly
changing speed if you want by turning it fast. The factory setting is 3. Lower
numbers lower the sensitivity and higher numbers increase the sensitivity to how
fast the knob is turned. If you enter a number outside this range it will not be
accepted and the cab will continue to wait for a number in the range of 0 to 7.
The valid range is 0 to 7.
Setting the OPTION key:
1)
Turn on the command station
2)
Unplug your cab from the command station
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
status LED.
4)
Press 4 to enter OPTION key setup mode. Notice the flashing of the LED
slows to indicating its ready to accept the new key value.
5)
Enter a new value for the OPTION key from the table on the next page, followed
by the ENTER key. If you enter a number less than 64 or greater than 128 the
LED will flash rapidly indicating an error. If you get an error press SELECT
LOCO to clear the error and go back to step 2.

Notes on OPTION key settings:
Some of the possible values for the OPTION key are impractical as they require
many visual prompts on the LCD of a ProCab. In the above table the most practical
key values are listed in bold type.
If you are adventurous you can try some other key values. We use Programming On
The Main fairly often.
1.
Set the option key value to 97
2.
Use Programming on the Main with your ProCab and record the key strokes to
access CV programming. (PROGRAM ON MAIN, ENTER, ENTER, 2, CV#, CV
value, ENTER [the last ENTER exits programming])
3.
Press OPTION on the Cab04 and notice the LED will light indicating data entry
mode. Press the keys you recorded in step 2.
