ARC-Series Controllers

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†.
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.
ARC Power Calculator
An ARCís 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 RC-3?
Standard two-conductor shielded twisted pair.
What types of parameters can ARCs control?
ARCs are extremely flexible and can be assigned virtually any real-time parameters depending on what host DSP it is controlling. Generally ARCs are used for volumes, buttons, and presets.
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†.
How do I lock and unlock an ARC-2e?
To unlock the ARC-2e, hold the ìMenuî button down for at least 4 seconds, then while continuing to hold ìMenuî, push the ìDownî button. If the ARC-2e needs to be re-locked to prevent tampering, simply do the same procedure but use the ìUpî button.
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 Composer 4.0+ software, simply type in the hardwareís 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 DSPs 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 Composer.
Can I resize the ARC-WEB Dialer to fit my screen resolution?
ARC-WEB and ARC-WEB Dialer will adjust to the deviceís 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 ìweb appî if using a smaller display device, particularly on those devices running iOS 8, as the bottom navigation buttons may be obscured by the browserís command bar.
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 ìEdit ARC-WEB Dialerî window each menu item is listed. Select the desired menu item and then click the ìEditî button. This will open an edit window for that menu item. Check the enable box and then click ìSave Menuî. 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 ìARC Descriptionî. 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 LEDís 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 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 LEDs?
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 ìauto-adjust brightness Settings for ambient lightî and ìbrighten button LEDs when buttons pressedî.
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.
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.
My ARC-3 remote is displaying a time that is out of sync with real time.
If your ARC-3 remote is displaying/reporting a time that is out of sync with real time (e.g.; the real time is 11:35am, but the ARC is displaying 6:35am, or some other time), push and go online with your DSP and system. Then go to Tools > Launch Event Scheduler. In the lower left panel, check that the time being displayed here is correct. If itís not, click ìSet Unit ClockÖî and choose the appropriate option. This should also update the time displaying on the ARC-3.
My ARC-3 remote is displaying Remote Disabled on the screen.
This is a feature with the ARC-3 that can act as a soft ìlockî, or the ability to enable/disable the ARC-3 based on the state of a system (room combining, for example). This relies on a certain remote control number within the Composer programming being active to ìenableî the ARC-3 remote menus. To remove this option altogether, un-check the box for ìDynamic ARC Enableî from the ARC-3 remote properties in the Remote Control Manager under the ARCs tab.
