Installation of IRL-3000 Software

To use the IRL-3000 to its fullest potential, you will need to install the IRL-3000 software on a

PC. While some of the functions for the IRL-3000 can be learned without a PC, functions including numeric direct access, macros, custom function labels, and alternate addresses can only be performed from a PC.

When using a PC to program the IRL-3000, you have several saving options, making it easy to re-use certain source setups for other projects. This will limit the time you spend programming sources and their respective functions. Furthermore, testing functions and source layouts can best be done using the IRL-3000 software.

The IRL-3000 (Ver. 1.5) comes with a disc containing the required software. The disc has an installer built in. To install the IRL-3000 software, follow these steps.



Insert the IRL-3000 software disc into your PC’s floppy drive (A).

From the Windows menu select







From the Run window select


From the Browse window select the

Floppy Drive (A).

Select Setup.exe

and double click on it to begin the installer. You can also select the

Setup.exe and then press the Open button.

The Run window will return. Press OK to begin with the installation of the IRL-3000 program.

After the installer is opened, the window to the right will appear. To continue with the installation of the IRL-3000 program, click the Next button.

- 2 -



Enter your name and company information. If this data is already on your PC, these fields may already be filled in. If this occurs and the information is not correct, please use this step to alter the data.

This step permits you to alter the destination of the installed software or rename the folders where the installation will take place. ADA suggests using the IRL-3000 folder option that is automatically displayed. The installer will create a folder labeled ADA and in this new folder, place the IRL-3000 folder. The IRL-3000 folder contains all of the IRL-3000 files and the

IRL-3000 program. Please note, that because the IRL-3000 Program relies heavily on the location of files and folders, if you are going to be using any number of PCs, in order for PCs to share IR code files, there file structures must be identical. As such, it is strongly recommended that you allow the installer to place all files.

10 The next window will simply display the information showing that the Setup status is complete, the target folders, and the user information. Click the Next button to finish with the installation of the IRL-3000

Software. Press Cancel to stop.

11 The next window permits the installer to finish with the complete installation. Press the Finish button to continue.

The window to the right will appear somewhere on your

PC’s desktop after the installation is complete. At this time, you can close this window by clicking on the X box in the windows upper right hand corner.

1 Introduction

The IRL-3000 is ADA’s new infrared controller. It communicates primarily to source components, transmitting learned source IR commands when a specific ADA Bus® command is received by the IRL-3000. The IRL-3000 replaces the PCT-8 and should be programmed using a PC and ADA’s Progada.exe software. The software is sold with the IRL-3000.

Since ADA’s software is designed to run on even the oldest lap-tops (often passed on to field technicians), you will find most prepackaged file names follow the 8.3 character DOS format.

To make certain that the files you save are available to other programmers, now or later, ADA suggests saving file names in the same 8.3 character format.

2 Terminology & Features

IRL-3000 terminology includes the following phrases.

IR File(s) - When an IR command is learned, you will have to save it as

an IR File, giving the IR command a file name. The name should be 8 characters long and will be followed by the suffix, “.ir”. You will want to create folders for different devices for easy sorting of commands. For example, when learning a Sony 7000 DVD player’s commands, create a folder called Sony7000. Then when learning each code, label it as “_

_ _ _ _ _ _ _ . ir”. The “_” can be used to label the function (i.e. For play, you can choose to save the file as “”. Because you will have several play functions, placing the “.ir” files in the correct folder will be key to your use of these files.

Source File(s) - Once you have captured a full set of IR commands for

a particular component (“.ir” files), you will want to link these functions to a specific button press and also label the function (for display on an

MC-3000, MC-3800, or TS-3000). For example, you will want to place the “play” function (“”) on the “>” button and label it “PLAY”. The

IRL-3000 permits up to 21 functions to be entered for a single component (19 of which are accessed from an MC-3800). Once you have linked all functions to their corresponding buttons, you can save this set of links as a “.irs” file or Source File. Once you have built a library of Source Files, you will be able to setup an IRL-3000 in miniuts. Therefore, you will want to spend some time making certain that your source files are perfect prior to saving them.

ADA Files - The third save level available allows you to maintain the

configuration of a particular project. This is extremely useful if many of your systems using an IRL-3000, utilize the same components accessed on the same ADA keypad buttons. Instead of adding Source Files, you can further cut down your IRL-3000 programming time, by simply recalling a template or ADA File (“.ada”). ADA Files again use an eight character name followed by the suffix “.ada”. You can even recall an existing “.ada” file and make changes to it. The “.ada” file contains links to each IR File (“.ir”) and their respective labels.

- 4 -















ADA Keypad Layout - The Progada.exe (the IRL-3000 pro-

gram) will bring up a layout of an MC-3800 keypad. By clicking on a source button, you lock in the transport functions for that IRL-3000 Port. If you select Src 2, the transport buttons will correspond to IRL-3000 Port 2. The software’s source buttons do not correspond to the sources on the ADA system. ADA systems provide provisions to lock a source button to a specific IRL-3000 Port number, as well as, ADA tuner module, or Escient special CD address. Thus, the

IRL-3000 software’s ADA Keypad Layout and Src # buttons refer only to IRL-3000 Port numbers. Also note, the function that is accessed when an ADA keypad’s source button is repeatedly pressed, the Main function, is located under the >> button on the ADA Keypad Layout.

Also, two other functions, not accessed by an ADA keypad, ON & OFF, can be programmed by selecting their respective buttons on the upper right hand side of the ADA Keypad Layout.

These two functions can be accessed by an ADA keypad if inserted in another function as a macro. The TS-3000 can access these two functions independent of a macro.

The IRL-3000 offers the following features.

PC controlled learning of IR commands.

Learning of IR commands directly on the IRL-3000.

IR learning through the IRL-3000’s built-in IR receiver (located on bottom side).

Saving learned IR commands as independent “IR Files”.

Testing of IR commands after they are learned (all testing is through IRL-3000 port 1).

Grouping function files for a component as “Source Files”.

Attaching Source Files on the “ADA Keypad Layout” and saving a loaded IRL-3000 as an “ADA File”.

Macro capability per button with 8 IR Files and 7 delay steps.

Labeling of each IR File (12 characters) on the “ADA Keypad Layout”.

Downloading of multiple Source Files simultaneously.

The IRL-3000 has the ability to offer data serial direct or data with IR carrier individually for each port.

The IRL-3000 has jumper pins which engage or disengage IR repeat through for each port individually.

As some components invert their data (serial links), you can provide invert the serial data per Port.

The IRL-3000 has multiple address (set during download) so that several IRL-3000s can be used on one system

(note that ADA keypads permit use of the IRL-3000 on address 1 {standard} or address 2).

Installation & Connections



Install the software as described on pages 2-3.

To perform any IR Learning, IR Testing, IR Downloading, and Testing (ADA Mode) of IRL-3000 after download, you will first need to connect the IRL-3000.

2 Connect the IRL-3000 to the ADA Bus®. The IRL-

3000 will require power from the ADA Bus®. If you do not have an ADA Bus® system or driver device (CIC-

3000, Delta-3, Delta-88, Cinema Reference, SSD-66

(5.1), Millennium 2000, or VS-3), a 12-15VDC (500mA) transformer will do. Connect (-) to pin 1 and (+) to pin

4 on the IRL-3000’s ADA Bus® terminal.

3 Press the button on the IRL-3000 in so that it is in the RS-232 position.

4 Using a standard 9 pin D ribbon cableor 9 pin D connector, connect the IRL-3000 to a com port on your PC.

Start the IRL-3000 program. You can do so by either opening the ADA folder on your C drive, then opening the IRL-3000 folder.

Double click on the Progada.exe. You can also open the IRL-3000 program by selecting Programs>IRL-





Com Port Selection

Once the program is open, the window to the right will appear. In order to move forward with any programming, you must first make certain that the program is communicating out of the correct com port.

To open the com port setting window, click on the Config button at the top of the window. The window below ill then open permitting you to set the program to the com port the IRL-3000 is connected to.

- 6 -

Special Notice Prior To Proceeding


You cannot run more than one ADA application at any one time.


The Progada.exe (IRL-3000 Program) software is time sensitive with respect to the

IRL-3000. As such, the software and the IRL-3000 need to be in sync with each other to perform most any function. It is important, that the IRL-3000 receive power and be swtiched to the RS-232 mode prior to opnening the software program. Also, switching back and forth between Program Mode and ADA Mode, assists in synchronizing the software and hardware.

This will be further discussed under the following sections.


The IRL-3000 program does not save the IR commands (.ir) for each job in a client file.

The client file (.ada) or component file (.irs) only contain place holders for were the IR files (.ir) can be found. Just like any map, these paths are very specific. Thus, prior to proceeding with the process of assembling component or client files, you will need to setup a series of folders and sub folders that you will be able to reference. Thus, as you proceed with the steps for capturing IR commands, you will be able to save them in the right locations, saving time and confusion later on.

ADA suggests setting up a folder in the IRL-3000 folder called IR codes. In this folder create a new folder for each brand (Sony, Pioneer, etc.) In each folder labeled for a particular brand, make a new folder for the model number of the devices you are using.

You can label these folders with either a model number or device type (DVD, VCR, etc.).




Capturing IR Commands

Press the IRL-3000’s ADA/232 button so that the button is locked down in the RS-232 position.

Open the IRL-3000 Program as discussed in step 5 on the previous page.

Gather the remote controls you wish to capture and familiarize yourself with the buttons and their respective functions.

- 7 -





If you have not yet done so, in your C drive, open the IRL-3000 folder. If one does not yet exist, create a new folder and label it IR codes. In this folder, create an new folder for each brand and in these folders, create new folders for each compoent. Keep the number of characters to eight when labeling folders.

Press the Learn IR button located at the bottom left of the window. A window will open instructing you to

“Aim remote control at IRL-3000 window and press button for 1 to 2 seconds.” At this time you will send the IR command for capture by the

IRL-3000. Again, only press the remotes button for one or two seconds. The software will continue to count down for a few more seconds after you release the button.

Towards the end of the count down, a “save as” window will open.

At this time, on the right of the Save As window, select the folder which contains the component specific folders you setup in step 4 and open it by double clicking on it. Then double click on the folder for the device that corresponds to this captured IR code. On the upper left of the Save

As window appears “*.ir”. Place your cursor behind the “*” and in front of the “.ir”. Backspace to delete the “*” and then type in an eight character name that describes this function. Then press OK.

You have now saved an IR Function File (.ir).

IR File

IR File

Again, press the Learn IR button and learn another command. Follow the instructions in Step 5 & 6 to learn as many commands as you need to. Note, that after you saved the first ir file, the Save As window shows a very long name: c:\ada\irl-3000\

Actualy, this is simply the name and location of the previously saved file. Simply highlite everything other than the “.ir. and now type the name of the next function. Then press save.

- 8 -

Testing IR Commands

1 You should test all the functions you have captured to make certain that the capture is accurate. When testing IR commands, only Port 1 of the IRL-3000 is active.

a b c d

Note: When testing IR codes, ADA strongly suggests using an IR flasher to test codes rather than a direct serial connection. As serial connections may require special wiring or grounding (see page 18), testing codes using a flasher will more accurately indicate if the code was learned correctly.


If you are using an IR flasher, position it over the first source you are testing.

Remove jumper pin 1 from the DATA/CAR area at the top of the IRL-3000 to engage the IR carrier.

If you are testing a source via its serial connector, leave the jumper in place.

If you are using a source that inverts the serial data, set the jumper pin for Port

1 from Norm to Invert.

Press the Test button located at the bottom left of the window. An

Open window will appear showing the folders you created on the right side. On the left side of the window are the codes that you captured. Navigate to the folder you wish to test on the right and then double-click on the desired function you wish to test on the left.

Once you double-click on the file name, the Function File is then accessed from the PC through the

IRL-3000 to the component.

3 Repeat the steps for each function you captured.

- 9 -

Source Files

Once you have built a library of IR Function Files (.ir), you can now apply the Function Files to specific keypad buttons and IRL-3000

1 Select a Src # button for the first component you want to configure. Once selected the Src # label will turn red or the button will become hi-lighted. Remember, the Src # has nothing to do with the components actual position on the system as each keypad can have its source buttons correspond to any

IRL-3000 port. However, ADA strongly suggests that if the component you are preparing to configure appears as the fifth source on the system, that its commands be configured on the fifth IRL-

3000 port (Src 5).




Select a function button. Once selected, the function label (>>) will turn red.

At the bottom of the ADA Keypad Display, click on the box under Action T/D. A pull down window will appear with the option of either setting a Delay or inserting a Transmit. Pull down to Transmit and click.

Under detail, double-click in the open window.

The Open file window will appear. Navigate to the appropriate folder on the right side of this window. Once in the desired folder, double click on the IR Function File ( and it will appear in the open window under Detail. Note that the window will display the path of the IR

Function File from your C drive through all of your folders.



In the window at the top of the ADA Keypad Display, you can type in a twelve character label to define the function (PLAY). This window will be displayed on the ADA keypads when the function is selected.

If you do not need to make this function a macro repeat steps 2 through 5 for each

Function File you need to configure for this source. For Macros, continue with step seven. If you are ready to program another component, proceed back to step 1.

- 10 -





For macros, you will typically need to provide some type of delay between IR functions. Click on the

Action T/D window for line 2 at the bottom of the

ADA Keypad Display. Select Delay from the pull down window. In empty area under Detail for this line, enter a value. As the delay is in milli-seconds, a typical low value is 50. For a one second delay, you will need to enter in 1000. Type in the delay you wish to set.

To enter in the next IR Function File, click on the

Action T/D window for line 3 and select Transmit from the pull down window. Double click on the open Detail box for line three and select the IR

Function File for your second macro step.

Repeat steps 7-9 for each macro level you wish to add. As the IRL-3000 permits up sixteen line functions per button and since each additional transmit function requires a delay, you can compile up to an eight step macro (fifteen lines total).

Saving Source Files (.irs)

11 Once you have finished assigning IR Function Files to each button you need for a particular source, you will want to save the source file.

Position the pointer (cursor) over the Src button and click the alternate mouse button. A window will open with two options, Load Source and Save Source. When you select Save

Source, a Save As window will open. With either the option “*.irs” or the path of the last file saved “C;\ada\irl-3000\” Simply highlite the “*” or the “C;\ada\irl-3000\lastsaved” and type in the name of the component who’s code set you are saving. Also, use the right side of the Save As window to place this “.irs” file in the appropriate folder (ADA suggests placing these files in the same folder as the “.ir” IR code files.

- 11 -

Loading Source Files (.irs)

12 After you have saved a Source File, you can re-load it on another button. You can also load the source file at some time in the future when configuring another IRL-3000 for a new client. As you proceed with the sales of IRL-3000s, these Source Files, if saved, will permit you to build a library of component files that allow for speedy programming of the IRL-3000.

To load a source file, click the source (Src #) that you wish to load codes onto. With the mouse (cursor) still over the Src button, press the alternate mouse button. The option of Load

File and Save File will appear. Select Load File.

An Open file window will appear. Use the right side of this window to navigate to the file you wish to attach on this Src button. When you find the desired “.irs” file, click on it twice or click on it once and then click the OK button. This “.irs” file will open, attaching all “.ir” codes, labels, and macros. If you wish, you can modify these files or labels.

Saving Customer Files (.ada)

13 Once you have finished the assigning IR Function Files to each button you need, for each IRL-3000 port you are using, you will want to save the customer file. Prior to proceeding with this step, you may want to create a separte folder marked as “Clients”. This folder should sit inside the IRL-3000 Folder. Again, because the

IRL-3000 software is extremely folder specific, creating a clear structure of where to save files, will optimize your use of the IRL-3000.

Under the File heading in the ADA Keypad Display, select Save or Save As. A Save As window will appear permitting you to select the saveto folder on the right and the Save As file name on the left. The file needs to be saved as an eight character name with the suffix, “.ada”.

Depending on what you last saved, the default name will appear as “*.ada” or some other file.

If the default “*.ada” appears, position your cursor between the “*” and “.ada” and backspace to delete the “*”. Then type in the name you wish to use (perhaps a project name or client name) and click OK. If another file name appears, select the entire file name and overwrite it with the client name followed by “.ada”.

- 12 -


After you have completed the Component Configuration of tested captured IR commands saved as IR Function Files, you can download the files to the IRL-3000.

1 In the ADA Keypad Display window click on Options and pull down to select Download.

At this time, the PC will download the IRL-3000, programming it with your codes and function labels.

You can now proceed to test the functions from either an ADA keypad or from the software directly.

2 For testing the commands from the software, disconnect nothing. See the steps below.

3 Testing functions from a keypad. Connect the IRL-3000 to the ADA Bus® (if not already connected). Press the IRL-3000’s ADA/232 button so that is in the up position

(ADA Bus). At this time, the IRL-3000 is ready for use.

Testing Source and Client Files




The IRL-3000 and its software permits you to test the programmed IRL-3000 without having an ADA keypad available. Furthermore, unlike the testing of individual IR commands as discussed on 9, this test requires that you use the ILR-3000 ports that you plan to use. All test codes do not come out of port 1.

To test the IRL-3000 in this manner.

1 Connect your devices to the appropriate IRL-3000 ports and set the jumper pins for that device.


Keep the IRL-3000 button pressed and in the RS-232 mode.

Make certain the IRL-3000 has power.

In the IRL-3000 software, under Options at the top of the screen, select Simulation Mode. The IRL-3000 software will connect to the IRL-3000 and a new window will open that looks simular to the window you have been working on, but is void of the programming options at the bottom.

At this time, you can select IRL-3000 ports, press functions, and check feedback labels. When you are done, select Options at the top of the window and Program Mode.

This will return the IRL-3000 to the program mode fromwhich you can proceed to download the IRL-3000.

- 13 -

Error Messages & Problems

a b c

If you are trying to load or operate the IRL-3000 make certain that the IRL-3000’s ADA/

RS-232 button is in the right position (Down for PC oriented functions, Up for ADA Bus control).

Make certain that correct com port is set in the Progada.ini file.

If you are receiving error messages of any type and your connections are in the proper place, you may need to synchronize the software and IRL-3000 hardware. To do so, switch the ADA Keypad Display software between ADA Mode and Program Mode.

Select either ADA Mode or Program Mode from the Options pull down window. Flip back and forth between these two modes a few times to synchronize software and hardware.

Programming the IRL-3000 without a PC





The IRL-3000 features buttons directly on it that permit you to capture IR codes without using a PC. There are several limitations when using the buttons to program the IRL-3000 without a PC.

a Each IRL-3000 port will only hold seven functions. The 12 numeric functions, on, and off cannot be programmed without a PC.

b You cannot program a macro without the use of a PC.

c Custom labels are only available when using a PC.

d. Macros can only be programmed using a PC.

e. The IRL-3000 will only be used as Address 1 unless previously altered during download.

You can program over an existing function, even if the function was programmed via a download. However, the previous label will be erased with a default label. To program an IR code directly on the IRL-3000:


Press the PRM button on the IRL-3000. The PGM and CON LED will light up.

Press both the Source (Port) number button and the function button (>) at the same time and release these buttons. Only the PGM button will stay lit.

Aim the remote control at the IRL-3000’s window and press the function button for one or two seconds. The PGM, DEL and CON LEDs will light up.

To exit programming, press the PGM button.

To learn another command, press the PGM button to exit (if you did not yet do step 4) and then press it again to enter it. You need to exit and return (PGM button) every time you learn a new code.

Appendix A

Systems with TS-3000 Touch Screens or

Keypads with Version Numbers Greater than 2.04


The MC-300 and MC-3800 family of controls operating with Version 2.04 software (1994-

1999) utilize a timing sequence when displaying feedback from either the PCT-8 or IRL-3000.

As a function is pressed on the keypad, the keypads microprocessor permits feedback from the IRL-3000 or PCT-8 to come in for only a brief moment. As such, when a function is pressed on one room’s keypad, only its display will read the feedback. If another room activates a function on its keypad, only its display is open to feedback. As such, no single keypad will constantly display IRL-3000 information when that information is intended for other rooms.

The TS-3000 operates in a different manner as its IRL-3000 feedback windows are open all the time. As such, ADA has added flags to the IRL-3000 feedback strings and has also designed the TS-3000 to read these flags prior to displaying the IRL-3000 information. For systems combining both TS-3000’s and MC-3000 (or MC-3800) keypads, the keypads will need to run on the newer software (greater than 2.04) in order to filter this feedback. Again, this feedback is not based on timing, but rather, based on feedback flags.

When using an IRL-3000 with the TS-3000, new MC-3000 (MC-3800) keypads, or a combination of these controls, prior to downloading the IRL-3000, you will need to instruct the program to add these flags to the IRL-3000.

1 After learning codes, testing codes, and laying the codes out on the buttons, click the check box marked as “Fill in feedback”. This will instruct the IRL-3000 to add the feedback flags to the feedback data string, after a function has been activated on the

IRL-3000. If you are using the IRL-3000 with MC-3000 or MC-3800 keypads version

2.04, leave this box unchecked.

2 At this time, continue with the downloading steps as described on page 13.

Appendix B

IRL-3000 Jumper Pin Settings & Other Controls

The IRL-3000 has several jumper pins and other settings directly on it. To ensure proper operation of the IRL-3000, you will need to set these pins correctly. Depending on whether you are using an IR flasher or direct serial connection, whether you are engaging IR repeating or not, you will need to set jumper pins on the IRL-3000 accurately.

STEP A - When using IR Flashers

When you are using an IR flasher, you will need to remove the jumper pin from the IRL-3000’s. These jumper pins are located in on the IRL-3000’s surface in the area marked

“DATA/CAR”. There are a total of eight (8) jumper pins marked 1-8 and these correspond to IRL-3000 outputs 1-8 respectively. For IRL-3000 ports which are using an IR flasher, remove just these pins. For sources controlled via a direct serial connection, leave jumper pins in place.


STEP B - IR Repeating (When using an IR Flasher either remove or set to the Left)

Each of the eight IRL-3000 ports can be set to IR repeat independently of one another. This means, that the components original IR remote control (or some type of learning remote) can be aimed at an ADA IR receiver, and the signal will be passed along the system bus, through the IRL-3000 and out to the source. The ability to independently select IR repeating per output is especially useful when using several identical components on the system. For example, if you had three DSS receivers on one IRL-3000, you could permit DSS #1 to be controlled via IR repeating while DSS #2 & #3 are controlled from keypads only.

If you do not want any IR repeating, simply pull the jumper pin located under the word “RE-

PEAT”. By doing so, IR repeating is inactive for this port.

If you leave the jumper pin in place, you have to make certain that it is set to the correct position. When using IR flashers, the pin should be set to the left under “IR”. If you

C are connecting to the source using a serial connector, the

“REPEAT” jumper pin must be set to the right under the letter “D”. Note that these settings must correspond to those made in Step A, above.


STEP C - Data Normal (also for IR Flasher) or Data Invert Settings

The “D D” jumper pin also needs to be set correctly in order for the IRL-3000 to control the component. When using a Serial connector, a source that does not invert its data (Sony or other similar sources) or when using an IR flasher, this jumper pin (C) should be set to the left above the word “NORM”. If you are using a serial connection for sources that invert their data (Pioneer or other similar), you need to set this jumper pin to the right above the word

“INVERT”. If you are using a flasher, the pin must be set to the left above the word

“NORM”. When using a serial connection, it is important to note that some components only ground through their RCA jacks. If not connected to a system, the source will need to ground from a chassis screw to Pin 1 on the IRL-3000’s ADA Bus jack.

The IRL-3000 has an adjustment which permits you to set the IR frequency. This adjustment applies only for ports that are set to IR repeating on and is affected only when IR repeating through the ADA network. Typically, you will want to keep this adjustment set to the factory default of 40KHz

(normal). Please note, that this adjustment affects all eight outputs.

Connecting a Power Supply to the IRL-3000 for

Programming away from System.

As mentioned on Page 6, you can connect the IRL-

3000 to a 12VDC (500mA) external power supply so that you can program and test the IRL-3000 prior to connecting it to the ADA System. The Diagram to the right illustrates the connection of the transformer.

Please note, that positive (+) connects to the ADA Bus® port Pin 4 terminal and that the negative (-) connects to the ADA Bus® port Pin 1 terminal.

Programming the IRL-3000 after installation

The IRL-3000 can be can actually be loaded by one of two methods. The most common method described in this manual is by connecting a PC to the IRL-3000’s 9 pin D connector.

For this method of programming, the RS-232 button needs to be pressed (inward). However, the IRL-3000 can also be programmed through its ADA Bus® data port. This will be

To ADA System

extremely useful, if the IRL-3000 is buried behind the equipment rack. To program it once it is installed, without removing it from the system or gaining access to the IRL-3000 and connecting to its 9 pin D connector, simply find an ADA Bus contact point, and connect a

ISO-232 RS-232 to ADA Bus® Convertor to the ADA Bus® line. The IRL-3000’s RS-232 button can remain in the upward (ADA) position when programming via an ISO-232 as the IRL-3000’s ADA Bus® connector is active during normal operation.

Serial Connections & Grounding Issues

Several source components are not grounded or are only grounded if the source’s RCA audio jjacks are connected to a grounded component. As such, direct serial control may not be possible without the connection of an alternate ground. Since many IRL-3000s may be programmed and tested with the sources away from the system’s installation, it will be necessary to apply a ground. The diagram below shows a Pioneer component grounded to Pin 1 (Gnd) on the IRL-3000’s ADA Bus connector. Please note, that not every chassis screw will act as an addequate ground. Typically, the pink chassis screws make for the best grounding point.
