How do I download the ARC-WEB dialer to my phone or mobile device?

No download is necessary.  ARC-WEB Dialer is a web app that is hosted on the Symetrix hardware.  After enabling and programming the ARC-WEB Dialer in SymNet Composer 4.0+ software, simply type in the hardware’s IP address into your web browser.

Does ARC-WEB Dialer work on a MAC or an iPhone?

ARC-WEB is supported on Mac OS X browsers and iOS devices.  It is also supported on Windows and Android browsers.  The supported platforms include: iOS version 6.0+, Android version 4.1+, Internet Explorer version 9.0+, Chrome version 29+, Safari version 6+: Mac OS X 10.7 or later, and Firefox version 24+

Is ARC-WEB Dialer available for the 2 Line VoIP Interface Card and/or the 2 Line Analog Telephone Interface Card?

ARC-WEB Dialer may be enabled/disabled for each telephony interface.

If I have more than one phone card can I still use the ARC-WEB Dialer?

For each phone interface in a site file, an entry will automatically appear in the RS-485 section of the Remote Control Manager under the four ARC-WEB instances. Any ARC-WEB Dialers will be labeled with DSP name, IP address and card slot the interface is plugged into.  A unique name can also be given to each ARC-WEB Dialer.

If I have multiple DSP's with multiple phone cards in the same site file, can I still use the ARC-WEB Dialer?

For each phone interface in a site file, an entry will automatically appear in the RS-485 section of the Remote Control Manager under the four ARC-WEB instances. Any ARC-WEB Dialers will be labeled with DSP name, IP address and card slot the interface is plugged into.  A unique name can also be given to each ARC-WEB Dialer.

Can I program/change and recall Speed Dial names and numbers from the ARC-WEB Dialer?

Speed dial names and numbers can be programed and/or changed using the ARC-WEB Dialer.  Simply click on the name and number you want to program and/or change. To trigger or dial the Speed Dial, select the Speed Dial number (1-20) under the line you want to dial out on. Any programming and/or change made to the Speed Dial name and number will also be changed in the VoIP or ATI module inside SymNet composer.

Can I resize the ARC-WEB Dialer to fit my screen resolution?

ARC-WEB and ARC-WEB Dialer will adjust to the device’s screen size and present a small screen (phone) or large screen (tablet / desktop) interface as appropriate. The minimum display size supported is 240×320 (640×960 Retina) pixels. It is recommended to save the ARC-WEB or ARC-WEB Dialer as a “web app” if using a smaller display device, particularly on those devices running iOS 8, as the bottom navigation buttons may be obscured by the browser’s command bar.

How do I lock and unlock an ARC-2e?

To unlock the ARC-2e, hold the “Menu” button down for 3 seconds, then while continuing to hold “Menu”, push the “Down” button. If the ARC-2e needs to be re-locked to prevent tampering, simply do the same procedure but use the “Up” button.

I am using the ARC-WEB Dialer but I have no volume or mute controls?

Each volume and mute control needs to be individually enabled.  In the “Edit ARC-WEB Dialer” window each menu item is listed.  Select the desired menu item and then click the “Edit” button.  This will open an edit window for that menu item.  Check the enable box and then click “Save Menu”.  For volume controls, you can also set the Low Limit, High Limit, and Resolution.

Can I have separate volume and mute controls for each Appearance on each line of the VoIP card with the ARC-WEB Dialer?

Each ARC-WEB Dialer instance controls two lines, two assignable volumes and mutes per line, 20 speed dial locations shared between lines, and 8 presets shared between lines.

If I use multiple ARC-WEB Dialers can I password protect each one separately?

Each ARC-WEB Dialer instance may be protected with a unique username/password.

Can I change the display text font on the ARC-3?

Yes, in the Edit ARC-3 windows you can change the “ARC Description”. You can also modify the Font, size and position of the text to be displayed. In addition, a background image can be imported (239×24 pixel monochrome bitmaps).

Can I lock or add security to the ARC-3?

Yes, a 4 digit security PIN can be enabled. This PIN will need to be used anytime the ARC-3 is activated or when the ARC-3 comes out of sleep mode.

How do I assign an address to the ARC-3?

In the ARC-3 edit window, assign the ARC-3 address in the RS-485 field located under the ARC Description.

Can I enable/disable Sleep Mode in the ARC-3?

Yes, in the ARC-3 Edit window you can choose to disable Sleep Mode by unchecking the box (Enable Sleep Mode). This box is checked by default. You can also adjust the delay time between 1-600 seconds of inactivity. In addition, you also have the option to keep LEDs on or turn LEDs off during Sleep Mode (default setting turns LED’s off).

Does the ARC-3 use the same wire pinouts as the ARC-2e?

Yes, the ARC-3 uses the same wire pinouts as all the ARC remote devices. The pinouts can be found in the help files.

Can I use the ARC-3 with Designer, Jupiter, or the Zone Mix 761?

No, the ARC-3 is currently only compatible with Composer 4.1 and above.

Can the ARC-3 display different languages?

The ARC-3 can display any character in any language that can be generated on a Windows computer.

Can I adjust the brightness of the ARC-3's LED's?

Yes, in the ARC-3 edit window you can adjust the brightness of both the idle and active states. You can also select or de-select “auto-adjust brightness Settings for ambient light” and “brighten button LEDs when buttons pressed”.

How do I enable dynamic menus within the ARC-3?

Dynamic Menu Enable – Check the box to enable an ARC or individual menus with controller numbers. Example: In a room-combine scenario, choose to display a separate set of menus when the room is combined and another when it is uncombined.

How do I change the address on the ARC-3?

Press both the left and right buttons, and then press and hold the top + portion of the slider. This puts the ARC-3 into system mode. Here an address from 1-99 can be selected.

How many ARCs can I daisy-chain together?

The number of ARCs that can be daisy chained together will vary depending on the type of ARCs used and the cable lengths.  Download Link: ARC Power Calculator.

Is the xControl programmed in the Remote Control Manager in SymNet Composer?

No, while the Control I/O was programmed in the Controller Manager in SymNet Designer, the same cannot be said about the xControl.  The xControl is added to the Site View of Composer just like a SymNet DSP. Once in the site file, the xControl is programmed to control parameters in the same way all control is programmed:

Right Click -> Set Up Remote Control-> Remote Analog Input –‘xControl’

Is there a template available to help me label the buttons on my Modular ARC?

Below is a PDF form which can be downloaded to your computer and used to produce labels for your Modular ARC (SW4, SWK, MIC, XLR and EX4 panels). Download the file linked below to your computer. Open the file with Adobe Acrobat. If you do not have Acrobat on your computer, it is freely available from Adobe. Once you have opened the document, you may type directly into the button label fields. The label text will auto-size from one large character to no more than three lines of eight characters each. Once you have typed up the labels you require, you may save your work for future use or print to the printer and paper of your choice..

SW4 Label Template

What cables are required to connect to ARCs?

A single standard straight-through CAT-5/6 cable will provide power and data to an ARC from the host DSP.  The daisy-chain to subsequent ARCs also uses CAT-5/6.

Legacy DSPs that pre-date the ARC Port (RJ-45) communicate to ARCs with a twisted-pair (A, B, Ground) for RS-485 data.  In this scenario a local external transformer provides up to 24VDC to the ARC.

What kind of cable do I use to hook up the RC-3?

Standard two-conductor shielded twisted pair.

Is the xControl an RS-485 device?

No, the xControl is a true POE device that communicates to the DSP hardware over Ethernet.

Where can I find an owner's manual for my Symetrix product?

All technical and operational instructions and documentation for current Symetrix products are contained within the Help menu of the Designer and/or Composer software. Simply click on the question-mark icon on the toolbar in Designer/Composer and search your topic.

How do I download the ARC-WEB to my mobile device?

No download is necessary.  ARC-WEB is a web app that is hosted on the Jupiter hardware.  After programming the ARC-WEB in the Jupiter software, simply type in the hardware’s IP address into your web browser.

ARC Power Calculator

An ARC’s power requirements vary depending on the voltage supplied to it. For example, an ARC-2e at 24V DC uses approximately 55 mA, while at 7V DC it uses approximately 170 mA maximum. As the voltage varies from 24 to 7 VDC, the current requirement increases accordingly. ARCs can be daisy-chained and fed power over this daisy-chain from an ARC-PSe or other device. However, as the length of the cable increases, so does the resistive line loss, which lowers the voltage available at each subsequent ARC. The actual power drain on each output from the powering device can vary substantially depending on the number of ARCs and the distance each of them is separated by. In order to assist with system design, Symetrix has available a Microsoft Excel spreadsheet that can help a system designer determine power requirements based upon cable length, number of ARCs and the power supply to be used.

What kind of cable do I use to hook up the Analog Control Inputs?

Standard two-conductor shielded twisted pair.

What distance can an ARC be from the host DSP?

The distance varies greatly depending on the type of ARC, the gauge of the cable, and the number of arcs chained together.  Download Link: ARC Power Calculator.

Can the xControl be powered from a Control I/O power supply?

No, the power supply for the legacy Control I/O is not compatible with the xControl.  A POE injector ships with the xControl.

Where can I download archived versions of Composer software?

Archived versions of all final public releases of Composer software are listed in the table below. The software runs on a Windows PC and is used to configure, design, and control Composer-based products. For new designs we highly recommend using the latest version of Composer, however archived major release versions can be found below for legacy compatibility and/or troubleshooting requirements. All firmware files are included as part of the downloaded Composer software package. The Composer firmware versions and Dante Kernels listed below are to help in cross-referencing the firmware running on the installed DSP(s) with the corresponding version of Composer that should be downloaded.

To communicate with Symetrix hardware from a given version of Composer, it may be necessary to upgrade (or downgrade) firmware in each hardware device. This can be done directly from the Composer application and only takes a few minutes per device. Firmware upgrade is done from the Composer Hardware menu.
