Startup
Here's what you will see when starting S-CAB Throttle: 

If the ‘CAB’ light is green and the display shows ‘L3’, you’re ready to send commands to decoder number 3, which was included in the starter package.

If the display shows ‘P’ followed by a number or just shows a 2-digit number, the throttle is not at zero.

If the CAB light is off and the CV light (yellow) is on, the display will show ‘C’ with a blank second digit. Move Mode switch to its CAB position.

If the display (especially the right-most digit) is dim, the battery may require charging. Plug in the USB cable and connect to a computer USB socket. If a computer is not convenient, buy an inexpensive powered USB Hub. It will only be used as a power source to charge S-CAB’s battery.

Speed control
If throttle position is zero, display will show ‘L3’ when S-CAB is turned on.
Move throttle from zero and display will show ‘P’ for power with a number, as you see to the left. Since the throttle provides 28 speed steps, values 10 and greater replace ‘P’ with either ‘1’ or ‘2’.

Depending on motor’s starting voltage, it may not start at ‘P1’ or ‘P2’, but it should definitely be spinning before reaching speed step ‘10’. If track voltage is adequate (12 volts) and the motor is not spinning, there is either a wiring problem or the motor has an undesirably high starting voltage.

Sound Decoders
Connecting a speaker allows sounds to be tested. Tsunami decoders use functions F0 through F12 to control sounds and other functions.

Press and release ‘FG1’ key. Display shows ‘F’ with blank.
Numeric key '1' toggles bell sound on and off.
'2' sounds the horn or whistle until released, and so on to F9.

To use functions 10, 11 and 12, 
Press and release the ‘FG2’ key. Display shows 'I' blank.
Numeric key '0' toggles function 10, etc.

Switching control between two or more decoders
When Throttle is turned on, default loco selection is '3'. Let's select a second loco, number 7, for example.

Press ‘Loco#’ key. Display shows ‘L3’.

Press ‘7’.

Press ‘Enter’. Display shows ‘L8’ and commands are now addressed to decoder number ‘7.

The state of all decoders to which commands are sent is memorized so that control can be switched between decoders without loss of information.
For example, repetitive pressing 'Loco#' cycles through memorized addresses; in this case, switching control between L3 and L7.

Charging Battery
The display’s brightness is the first indication to recharge the battery. The battery’s protective circuit will automatically shut off to protect the battery against over-discharge. Use the USB socket, left side of the CAB to re-charge the battery.

---

---

Direction Switch
When in right-hand position, the decoder command is always forward direction. With decoder installed in a loco, direction of loco movement is determined by motor connections. If forward direction command moves loco backwards, flip motor gray and orange connections.
Left-hand position is always a backward direction command.

---

Buttons
Loco# selects loco number.
Speed button turns numeric keys into 9-step speed control.
FG1 turns numeric keys into function keys F0 to F9.
FG2 turns numeric keys into F10 to F12 plus some Throttle configuration keys.
HALT is emergency step.
ALL activates broadcast command. For example, 'ALL', 'HALT' is all loco emergency stop.

Lights and direction control
Turn on decoder power. Depending on decoder, lights may be on or off.

Press and release ‘FG1’ key. Display will show ‘F’ with blank.

Press numeric key ‘0’ one or more times until one of the lights turns on.

Each time ‘0’ is pressed, light toggles on and off. If direction switch is to right, it's the headlight that is switched on and off.

With headlight on, move direction switch to its left. Headlight turns off (or dims) and rear light turns on.

Changing a Decoder’s Address
Independent control of two or more decoders requires that they have different addresses. If planning to install decoders in other locos, this is a good time to change the decoder’s address.

Switch Throttle off and back on. Make sure ‘L3’ is displayed.

Move Mode switch to its ‘CV’ position. CAB light turns off, CV light turns on and display shows ‘C’ with blank second digit.

Press 'ALL' key. Commands will be transmitted in broadcast mode. Be sure to turn off all radio receivers except '3'.

Press ‘C#’ key. It’s the same key as ‘FG1’, but selects a CV number when Throttle is in CV mode. Display shows ‘C1’, which is the CV number for decoder’s short (primary) address and is the variable we want to change.

Press ‘C=’ key. Throttle displays ‘U3’, where ‘3’ is the default address value, which is not what we want. (Note the prompt, ‘U’ for valUe.)

Use numeric keypad to select an address value; number 8 for example. Display shows ‘U8’.

Press ‘Enter/Send’ key. Display shows ‘L8’ and a motor connected to the decoder jerks to acknowledge that address has been changed.

Return Mode switch to its ‘CAB’ position. CV light turns off, CAB
light turns on, and display continues to show ‘L8’.

Send a direction or speed command to be sure decoder responds to commands sent to ‘8’; its new address.
