2 GETTING STARTED

The software required to program the Leviton 41920-C8F 8 Button Control Panel is supplied with the control

panel on a USB drive and available online at Leviton.com.

2.1 Install the Software

Programming software is for Windows based machines only. The software is an executable ﬁle that

can be run directly without installation. Best practices are to create a folder on a PC drive, protected

portable drive or other secure location and run the software from this folder. When the software is run

for the ﬁrst time and a Library is created as described in a later section, a new folder called “Library”

and an additional ﬁle called “wpsetup” will be created in the folder from which the software is opened.

The ﬁles will auto locate in the root folder where the software is installed. All work performed to create

libraries is stored in the “Library” folder. It is critical that this folder is stored in a secure location to

protect the work of the programmer. The names of the library ﬁles cannot be changed in the ﬁle

explorer. All library ﬁle names can be edited only from within the Leviton software.

Before opening software:

4 PROGRAMMING A BUTTON

Before Events can be added to a button, a button must ﬁrst be setup with its behavior when pressed or

held. These are called Action Types (Press, Release, Page or Toggle). Follow the procedure below to

setup the Action Type as well as other settings for each button on the panel.

1. Click on the button to be programmed in the Button

Selection area. A new window will open.

2. Enter a name for the button (4 characters maximum).

This will appear in place of the default numbers.

3. Select a default brightness for the blue LED button

backlight:

Off or Level 1 (dimmest) through Level 9 (brightest).

This value can be overridden in Event settings for a

button action.

4. Set the Repeat Interval. If the button is to control a ramping feature (e.g. Volume Up) in which the

command will repeat until the button is released, Repeat Interval determines the ramp rate. The

interval selected determines how often the command is repeated. Lower Repeat Interval time equates

to faster ramping.

5. Select an Action Type from the dropdown list.

Press – Initiates an Event and continues while the button is pressed.

EXAMPLE: Start sending Volume Up IR commands to a device and continue ramping

volume while the button is continually pressed at a speed determined by the Repeat

Interval.

Release – Initiates an Event when the button is released.

EXAMPLE A: Turn on the button LED after a button has been released.

EXAMPLE B: Initiate action for a button when the button is released instead of when

pressed. This can reduce repeat hangups in public spaces with multiple operators. Best

used with complex multisystem operations such a System ON or OFF.

Page – Changes the parameters and/or functions of other buttons.

Toggle – Changes from one parameter to another each time the button is pressed.

Toggle Class – Describes the number of different commands that the button will transmit

until it repeats.

Toggle Number – Deﬁnes each of the Toggle Classes.

EXAMPLE A: A single PWR button will turn the power of a device on or off each time it is

pushed = Toggle Class 2.

EXAMPLE B: A display with 2 HDMI and one VGA could toggle via a single button called

SRC (Source) = Toggle Class 3.

Toggle Number 1 = HDMI1

Toggle Number 2 = HDMI2

Toggle Number 3 = VGA

6. Click Add Action. This will rename the button in the Button Selection section of the software and the

new Actions will be displayed in the Action List section as shown below.

WEB VERSION

5 ADDING EVENT(S) TO A BUTTON

Events are actions the controller takes when a button is activated (Press, Release, Page or Toggle). These

Events can include sending RS232 commands, IR Commands, Relays, Delays, repeats, etc. Events can

stack and are processed in series.

EXAMPLE: The press of a single button (labelled ON for example) can direct the controller to send

RS232 (Power on) to the AV receiver, send RS232 (Power on) to a projector, send an IR (Power On)

to an optical media player, wait for 2 seconds, send a dim to 20% command to a lighting controller, and

send a relay command to the motorized shades (down).

NOTE: This control panel operates serially. If a long sequence button command string is running and

another button is pressed, the ﬁrst series will be interrupted. For this reason, long series commands or

boot sequences are discouraged. Best practice is to keep command strings as short as possible.

1. In the Button Selection area, click on the button to be manipulated.

2. In the pop-up Button Action area, click the Action Type drop-down box. Refer to the Programming a

Button section for details on the options presented. Then click Add Action.

WEB VERSION

5 ADDING EVENT(S) TO A BUTTON

3. In the Action List section, click on the button action just added.

4. In the Event Settings section, select the tab that corresponds with the type of action you would like the

button to take.

RS232 – Send a serial RS232 command from one of the rear RS232 ports to a device.

IR – Send an IR command via an IR emitter connected to one of the rear IR ports to a device.

Relay – Change the state of one of the relays on the control panel.

On = Closed

Off = Open

Delay – Add a delay to the string, typically used if multiple commands are to be sent from a single

button push.

EXAMPLE: Send IR Power On; Delay 2 seconds; Send IR input to HDMI 1.

Compare – Not Used.

LED – Sets the LED button light level for the selected button.

Page – Not Used.

Loop – Not Used.

Toggle – Not Used.

WEB VERSION

5 ADDING EVENT(S) TO A BUTTON

5 For RS232 or IR commands, check that the device library to be accessed is in the Library Name box.

If it is not, click Browse. Select the device library from the dialog box. If the device library is not present,

see Create Libraries section for details.

6. Within the selected tab, select the function or action to be performed. Click Add Event. The event will

be added to the Event List section.

7. Continue adding Events as needed to complete the action intended for the button.

8. Repeat steps 1-8 for all buttons.

NOTE: Remember to save often.

EXAMPLE: A button labelled ON may be programmed to turn on multiple devices by triggering several Events.

A room system may include:

• A projector connected to RS232 port 1

• An electric projection screen connected to Relay 1

• A Leviton 41920-A70 ampliﬁer connected to RS232 port 2

• An optical media player connected to IR port 1

Program the button events to perform several events in series. Adding a delay between the projector power-

on signal and the amp unmute signal can be used to eliminate any pop or beep sound from the projector

start up process.

Event List

1 – RS232 – Function:Mute – MIC & LINE

Mute all audio from the ampliﬁer.

2 – RS232 – Function:Power_on

Send a “power on” signal to the projector.

3 – Relay – Port 1 on

Close relay one to trigger a screen drop for the projection screen.

4 – Delay – Time 10 seconds

Delay 10 seconds to wait for the projector to power up.

5 – RS232 – Function:INPUT 1

Set ampliﬁer input source to Projector input (1).

6 – RS232 – Function:Unmute_Audio

Send an unmute command to the ampliﬁer.

7 TIPS AND TRICKS

Save often!

• Save after every Library entry.

• Save after each Button Event addition.

Before doing anything, create a drawing of the entire system. Include in the drawing:

• All connected devices.

• Labelling for the connected ports of the devices (what is connected to what).

- Ensure all connectors pinout correctly and that all connectors are compatible.

- Ensure all cable distances will be within spec and that the cables intended for the project are long

enough.

• Labelling for the control protocols supported by each device.

• Determine the best communications method and cabling required to support it. Consider an IR

blaster for stacked equipment.

• Label the cabling, pinouts, and color schemes on the drawing for future reference.

Before going to site:

• Bench test the entire system.

• Gather all components to be installed on site and connect them as intended.

• Test and modify the controller program before going to the jobsite.

• Thoroughly test all operations and functions of the system before taking to the jobsite.

Serial RS232 and RS485 commands are supported.

• RS232 Serial command code sets must be located and documented before designing a system.

• RS232 commands vary considerably from vendor to vendor. If in doubt, contact the device vendor

for assistance in constructing the commands.

• Serial command sets, including communications parameters, are available from the controlled

devices manufacturer and may be found in instruction manuals, online resources or a phone call to

the manufacturer.

• Maintain serial command sets for future use.

• Communications parameters that are required before programming can be completed include:

- Baud Rate

- DataBit

- Stop Bit

- Parity

- Format (ASCII or HEX)

- ASCII End Character(s)
