Frequently Asked Questions - ACP VC1 D Extron

How do I change the button on the ACP VC1 D?

Remove the two screws holding the plastic faceplate. Insert a small flat-bladed screwdriver into the notch at the top of the button plate to release the catch. Repeat for the bottom. Tilt the button plate forward and remove the button by pressing it backward through its slot. To install a new button, align the pegs on the button membrane with the holes on the back of the button plate and push forward. Reattach the button plate and faceplate.

How do I set the bus ID address?

Use the 6-pole DIP switch on the left side of the ACP VC1 D. Switch 1 (leftmost) is the most significant bit (value 32), and switch 6 (rightmost) is the least significant bit (value 1). Set the switches to create a unique binary address for each panel. Valid addresses are 1 to 8 (binary 000001 to 001000). Address 0 is reserved for the controller.

How many ACP panels can be connected to one host?

Up to eight ACP panels can be connected to a single host device. Each panel must have a unique bus ID address to avoid conflicts.

What does the status LED indicate?

The LED on the rear panel lights green when power and communication are present and there are no bus ID conflicts. Refer to the legend on the back of the panel for other LED behaviors, such as flashing for errors.

How do I cable the ACP VC1 D to the host?

Use 4-pole captive screw connectors on both ends of the cable. Wire both ends identically: V+ (power), A (data+), B (data-), and GND. Extron recommends STP20-2/1000 or STP20-2P/100 cable. Power is typically supplied by the host device. For long distances, an optional PS 1220EB power inserter can be used.

What software is required for configuration?

You need DSP Configurator software to configure the host device and ACP panels. Install the latest version from www.extron.com. Also ensure you have the appropriate firmware and drivers for the host device.

Can I mount the ACP VC1 D without a mud ring?

If not using a mud ring, you must install the included plastic spacer to allow the plastic faceplate to attach properly. The unit must be mounted in a UL Listed junction box or mud ring for safety and code compliance.

What power supply is needed for the ACP VC1 D?

The ACP VC1 D is typically powered by the host device via the ACP cable. If additional power is needed, use an Extron PS 1220EB eBUS power inserter or a 12 VDC desktop power supply. Refer to specifications at www.extron.com for guidance.

How do I troubleshoot if the panel is not recognized?

First, check that the bus ID DIP switches are set to a unique address and that the LED is green. Verify that all cables are wired identically and securely. Reconnect and power cycle the host. Use DSP Configurator's Live mode to push the configuration and check DataViewer for command responses.

Is the ACP VC1 D compatible with all Extron devices?

The ACP VC1 D is designed for use with Extron ACP-enabled host devices. Check the host device's user guide to confirm compatibility. It supports up to eight panels per host and works with DSP Configurator for configuration.

Installation

Step 1: Get Ready

Use the following checklist to prepare for installation:

☐ Download and install the latest software, firmware, and device drivers needed to configure the host device and the connected ACP devices (see the host device user guide, available at www.extron.com, for details regarding software and drivers).
☐ Obtain cables, mounting hardware, and any other supplies required for the installation.

Step 2: Prepare the Installation Site

ATTENTION:

NOTE: For the installation to meet UL requirements and comply with National Electrical Code (NEC), the ACP VC1 D must be installed in a UL Listed junction box. The end user or installer must furnish the junction box. It is not included with the ACP VC1 D.

Americans with Disabilities Act (ADA) Compliance

When planning where to install these devices, consider factors affecting accessibility of the button panel such as height from the floor, distance from obstructions, and how far a user must reach to press the buttons. For guidelines, see sections 307 ("Protruding Objects") and 308 ("Reach Ranges") of the 2010 ADA Standards for Accessible Design available at http://www.ada.gov/regs2010/2010ADAStandards/2010ADAStandards.pdf.

Site Preparation

Extron offers an assortment of mud rings, optional UL Listed in-wall junction boxes, external wall boxes (EWBs), and surface or tabletop mounting boxes for use with the ACP button panels. The ACP VC1 D is a US 1-gang size device.

Step 3: Removing the Plastic Faceplate, Removing the Button Panel, and Changing the Button

The plastic faceplate and button can be replaced. Additional buttons ship with the device and others can be ordered from www.extron.com.

To change the button:

1. Remove the two screws holding the plastic faceplate to the metal mounting plate and separate the faceplate from the button plate (see ① in the figure to the right).
2. Insert a small flat-bladed screw driver into the notch at the top of the button plate. Release the catch holding the button plate to the metal mounting plate (②).
3. Repeat step 2 to release the catch at the bottom of the plate.
4. Tilt the top of the button plate forward as it is removed to prevent the button from falling out.

1. To remove the button, press the button backward through its slot in the button plate until the membrane containing the button is free (see 1 in the figure to the right).
2. To replace the button, align the two pegs in the button membrane with the holes located at opposite corners of the empty slot on the back of the button faceplate and push the button forward so it fits in the slot (2). Ensure the button text orientation is correct.
3. Align the button plate with the metal mounting plate using the pegs on the rear of the button plate as guides.
4. Snap the button plate into place.
5. Reattach the plastic faceplate using the two screws removed in step 1 on the previous page.

Step 4: Set Bus ID Address

Set the bus identification (bus ID) DIP switches for the ACP VC1 D and any other ACP panels being connected to the system. Each ACP device must have a unique bus ID. If multiple panels have the same bus ID, address conflicts may cause one or more of the panels to not be recognized in DSP Configurator or by the host device. Up to eight ACP devices can be connected in the same system.

Setting the Bus ID Address

Each ACP device in a system must have a unique six-digit binary bus ID. ACP bus IDs are set using the DIP switch assembly on the left side of the ACP VC1 D (see E on figure 1 at the beginning of the guide).

Switch 1 on the left sets the most significant bit (highest number, 32) while switch 6 on the right sets the least significant bit (the lowest number, 1). See the example addresses to the right.

Step 5: Cable All Devices

1. Connect the ACP panel to the host device.
2. Connect ACP panels to each other if multiple panels are used in the system (see the wiring diagram below for correct wiring).

NOTES:

• Wire both ends of each ACP cable the same. Connectors are interchangeable between the host device and ACP devices.

• Do NOT power an ACP panel from more than one power source.

• Apply power to the host device after correctly cabling all devices.

Cabling

Attach cables using the diagram below as a guide. Wiring is the same for all ACP models. Connect a 4-pole captive screw connector to each end of the cable, wiring both ends the same. In most cases, ACP devices are powered by the host device. Power is carried on the V+ pin of the ACP VC1 D and other ACP devices.

Extron STP20-2/1000 or STP20-2P/100 cable is recommended for ACP device connections.

ACP devices that are relatively far from the host device can be connected to an optional Extron PS 1220EB eBUS power inserter or an Extron 12 VDC desktop power supply as shown in the diagrams below and on the next page (see the ACP VC1 D Specifications at www.extron.com to determine if additional power is recommended).
