Description

The SC82 is a DCC compatible accessory decoder.

It can control up to 8 servo motors that can be used

for switches (turnouts) or semaphores. It can drive

LEDs for turnout state. The inputs can be used for

push buttons to control switches or block detectors to

control semaphores. It has route capability for

multiple turnout control.

The SC82 can be used as a stand-a-lone controller or

communicate with other devices that have a

compatible serial bus.

Using the serial bus, one SC82 could control another.

Push buttons connected to the inputs of one SC82

can control servo connected to another SC82. A route

defined in SC82 could include servos controlled by

another SC82. The serial bus can help in reducing

and simplify the wiring.

The SC82 works out of the box with no

programming. If you you need to change servo

position or addresses its as easy as issuing switch

commands or controlling loco speed. If custom

operation is required, CVs can by programming by

the DCC system.

1 Operation

The SC82 is capable of driving eight servo motors. Each output (servo) can individually be assigned any switch (turnout)

address. It has eight inputs for local control of the outputs and eight programmable routes.

There are two modes of operation. The modes are based on how the servo is used. All servo outputs function in either mode 1

or 2 i.e. modes can not be mixed between servo outputs.

The first mode is moving all servos to two positions (default).

Mode 1 - The servo outputs can be used for switch (turnout) control. There is a separate switch address for each output so

they can be controlled individually. There are a total of eight switch addresses used.

The second mode is for moving all servos to three positions.

Mode 2 - The servo outputs can be used for semaphore control. There are 24 switch addresses used. In this mode three

addresses are used to control each servo, address A(throw) will command the servo to one end, address A+1(throw) will

command it to the center and address A+2(throw) will command it to the other end.

The SC82 supports routes. A route allows for the control of multiple switches (turnouts) with just one switch command. Each

route is made up of eight cells (switch addresses) and one top level address (or route execution switch address). Each top

address is completely independent of a servo address. Complex routes with more than eight servo addresses can be created by

assigning the same address to more than one top level address. Routes are executed by issuing a switch command.

Since the SC82 is an accessory decoder, it can be controlled via DCC commands. It can also be controlled via the serial bus

(LocoNet® compatible). For non-Digitrax systems a DCC gateway feature allows DCC switch commands to be passed

directly to the serial bus. This allows DCC switch commands to control devices connected to this serial bus.

1.1 LED Indicators

LED 1 flashes indicates “Smart” programming. LED 2 flash indicates accepted program value or a valid received address.

LED 3 slow flash indicates heartbeat and fast flash indicates serial bus short.

2 Getting Started

The SC82 comes from the factory ready to use with addresses of 1 to 8. Once you plug in the servos cables, centered the

servos (section 2.2) and mounted them you are ready to use the SC82. If you want to change some of the addresses or adjust

servo movement see the “Smart” Programming section. For very custom programming see section 4, Configuration Variables

for various options. Before doing any programming, it is strongly recommended that you verify basic operation.

2.1 Control via LocoNet - Digitrax Users

The SC82 comes from the factory ready to use by control from DCC commands when it is connected to track power. To

control the SC82 via LocoNet®, it must be enabled. LocoNet® can be enabled using section 3, “Smart” programming Part 3 or

the programming track. If the programming track is used, connect the SC82 track power terminals to the programming track

and program CV9 with a value of 48. The SC82 can now be powered from a 12 volt supply and controlled via LocoNet®.

2.2 Servo Mounting

Before mounting and/or linking the servo arm (horn) to the turnout or semaphore, the servo should be centered and then the

arm attached so that when linked the turnout or semaphore will be in the approximate center of their travel.

To center the servo, press the Smart button then turn on power and continue to press the button until LED2 (green) begins to

flicker. Several seconds after releasing the button, all the servo will move to the center position.

NOTE: for mounting orientation it may be useful to know that a turnout throw command causes the servo to rotates CCW

when viewing the servo shaft (factory default operation).

2.3 Servo Move Direction

It may be that after you have installed the servos issuing a close or throw command causes the switch to move to the opposite

intended position. That is, close causes the switch to move to the thrown position. The direction can be reversed without

programming if a push button is used for switch control. To reverse the servo direction press and hold the “Smart” program

button until after power is turned on. If LED2 (green) begins to flicker you have pressed the “Smart” button too long. After

power has been on for at least 5 seconds, press and hold the respective push button for the servo to be reversed for at least 4

seconds. Direction can also be changed in “Smart” programming Part 2.

2.4 Switch Position Indication

If LEDs are used to indicate the status (position) of the switch on a panel or facia, they will flash during the time the

respective servo is moving. It may be that after they are installed that the lighted color does not match the switch position.

That is, green may be lit instead of red. The lighted color can be reversed without programming if a push button is used for

switch control. To reverse the lighted color during normal operation, press and hold the push button for at least 4 seconds.

Once you notice the change release the button. The LEDs may be

flashing during this time. Also the SC82 must NOT be in the same

mode as when change the servo direction mode.

3 “Smart” Programming

“Smart” programming is a term used to describe an easy way to

program Configuration Variables (CVs). A controller (any device used

for locomotive or switch/accessory control) is used to issue switch

(turnout) or accessory commands. Additionally, loco speed commands may be used.

“Smart” programming only works when the SC82 is connected to track power.

There are three parts to “Smart” programming. You can:

1. change the addresses of the inputs and servo outputs, either for switch control (two servo positions) or semaphore control

(three servo positions).

2. change the amount of servo movement and positions.

3. set the SC82 configuration and status report options.

To program in “Smart” mode, connect the SC82 power terminals to track power. The serial bus (LocoNet® in Digitrax

systems) should NOT be connected to the SC82 during “Smart” programming.

To start turn on track power. Wait 6 or 7 seconds.

You can start from any part. Also at any time you can exit “Smart” mode by pressing the button for approximately one second

until LED1 stops flashing.

Part 1: To change addresses and mode, press the “Smart” program button and hold it down for approximately one second

until LED1 (red) starts to flash. Then release it. The SC82 is now ready to have the addresses changed. You can set eight

sequential addresses in one (first) step or continue and set each of the individual servo addresses (non-sequential). Input

addresses are also changed. SC82 Configuration is unchanged.

Eight sequential addresses:

Using the controller select the switch address or accessory number you want for the start of eight sequential addresses and

issue a close (normal) command for two positions (mode 1). Issue a throw (reverse) command for three positions (mode 2).

Now press the “Smart” button until LED1 stops flashing, the SC82 will restart and be ready to use with the new addresses.

Non-sequential addresses:

Using the controller select the

switch address or accessory number

you want for the first servo output

address and issue a close (normal)

command for 2 positions (mode 1).

Issue a throw (reverse) command

for 3 positions (mode 2). LED1 will

be flashing twice with a pause and

then repeats indicating that the servo

2 output address is ready to be

programmed. Select the switch

address you want for the second

servo output address and issue the

same close/throw command as in

step one.

Servo 2 position and 3 position modes can NOT be mixed.

After the last step the SC82 will restart and be ready to operate

As you progress through the “Smart” programming steps, LED1 flashes the number of times indicating which servo output is

ready to be programmed. After the 8th step the SC82 will restart and be ready to use with the new addresses.

Note: servo 3 position (mode 2) used for semaphore requires 3 addresses, one for each position. Enter only the first address

and be sure to skip at least 3 addresses when programming. You can exit “Smart” programming after any step by pressing the

“Smart” button until LED1 stops flashing.

Part 2: To change servo position press the “Smart” program button and hold it down. After about a second LED1 (red) starts

to flash. Continue to hold it down until LED2 (green) turns on. Then release it. LED1 will be flashing and LED2 will be on.

The SC82 is now ready to have the servo movement changed. You need to be able to see the servo arm, switch or semaphore

to make adjustments.

Using the controller select a loco address (not a switch address) that corresponds to the servo output (1-8) that is to be

changed. For example select loco 2 for output 2. Adjust the speed of the loco to move the servo. Set the loco to forward to

move the servo in one direction, set the loco to reverse to move it in the other direction.

To program the switch position for close, use the manner just described and move the servo to the position you want it to be

in when closed. Now issue a switch close command with address 1.

To program the turnout position for throw, use the manner just described and move the servo to the position you want it to be

in when thrown. Now issue a switch throw command with address 1.

The switch address (1-8) is used for programming the servo position of the respective output. If a switch address higher then

8 is used, the SC82 will restart and be ready to use with the new positions. You can also exit “Smart” programming by

pressing the “Smart” button until LED1 stops flashing.

Note: The controller must be set for 128 speed steps and there should not be any other locos addresses selected in the 1-8

range.

Part 3: To change the SC82 Decoder Configuration and/or the Status Report options press the “Smart” program button and

hold it down. After about a second LED1 (red) starts to flash. Continue to hold it down until LED2 (green) turns on and then

off. Then release it. The SC82 is now ready to have the options changed. LED1 (red) will be flashing.

The CV value is the switch address you select. For example, to enable the serial bus and disable DCC control for a Digitrax

system select a switch address of 48 and issue a throw command.
