Product Information

AXB-DTMF+ DTMF+ Interface

Product Information

The AXB-DTMF+ DTMF Interface (FIG. 1) links an Axcess central controller to a telephone

network, enabling dual tone multi-frequency (DTMF) and audio pass-through control. The AXB-

DTMF+, with a programmed central controller, processes incoming calls and initiates outgoing

calls to any pager or cellular phone.

The multi-function AXB-DTMF+ can be integrated for many imaginative and creative purposes

within a home or work environment using touch-tone control. For example, the AXB-DTMF+ can

announce callers by caller ID data, or can set up an audible menu selection to process incoming

calls for routing.

The audio pass-through can be used with an AXC-SPE Enhanced Speech Synthesizer card, or PC

sound card to produce audible menus, monitor phone audio, or provide audio input such as music

on hold. The AXB-DTMF+ allows a user to issue instructions to the AMX Central controller from

a remote location using any touch-tone telephone.

The AXB-DTMF+ receives and decodes DTMF audio signaling and sends the decoded data to the

central controller for the switching/controlling of any devices connected to the central controller.

An Axcess program written on a personal computer, and downloaded to the central controller,

enables the central controller to interpret the data received from the AXB-DTMF+. The program

may also issue menu selections over the telephone through an optional AXC-SPE card. For more

information about programming a central controller, refer to the Axcess Programming Guide.

Configuration and Installation

AXB-DTMF+ DTMF+ Interface

Configuration and Installation

Setting the Internal Jumpers

There are two 2-position jumpers on the AXB-DTMF+ circuit card (FIG. 1). Each jumper is set to a

default pin setting. These jumpers are positioned to enable automatic call answering and select line

setting for a leased line or phone operation.

Auto Answer mode

The 2-position jumper JP2 selects auto answer ON or OFF mode when the system powers on.

When the auto answer is on, the AXB-DTMF+ answers on the ring set by the Send_Command

COUNT-XXX. If the ring count is set to 3, for example, auto answer picks up the call after the

third ring. The default count is 1 ring. The default jumper setting is shown in FIG. 2.

To change the auto answer default from ON to OFF:

1. Remove the AXB-DTMF+ unit cover.

2. Remove the jumper from pins 2 and 3, and place it on pins 1 and 2.

3. Re-install the AXB-DTMF+ cover onto the unit housing.

The 2-position jumper JP1 selects PHONE or LEASED line operation when system powers on.

FIG. 3 shows the default setting.

To change the line setting default from PHONE to LEASED:

1. Remove the AXB-DTMF+ cover from the unit housing.

2. Remove the jumper from pins 2 and 3, and place it on pins 1 and 2.

3. Re-install the AXB-DTMF+ cover onto the unit housing.

Wiring the AXB-DTMF+

Preparing captive wires

To connect the wiring into a captive-wire connector:

1. Strip 1/4 inch off the wire insulation for all four wires.

2. Tin 2/3 of the exposed wire.

3. Insert each wire into the appropriate captive-wire connector up to the insulation.

4. Tighten the captive screws to secure the fit in the connector.

Wiring guidelines

The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8 power

suppl. The Central Controller supplies power via the AXlink cable or external 12 VDC power

supply. The maximum wiring distance between the Central Controller and interface is determined

by power consumption, supplied voltage, and the wire gauge used for the cable. The table below

lists wire sizes and maximum lengths allowable between the AXB-DTMF+ and Central Controller.

The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts

available at the Central Controller’s power supply.

Configuration and Installation

AXB-DTMF+ DTMF+ Interface

Connecting External Telephone Lines

Telephone cabling for both the input and extension lines are standard RJ-11 type connections.

Follow these steps to connect external telephone lines.

1. Check the circuit card jumper settings to match line type and auto answer mode. For more

information, refer to AXB-DTMF+ Jumpers in the Pre-Installation section of this manual.

2. Connect the AXlink cable to the Axcess Central controller AXlink input.

3. Connect the male RJ-11 jack of the incoming telephone line input to the AXB-DTMF+ LINE

jack and the extension telephone cable to the PHONE jack on the rear of the AXB-DTMF+.

4. Adjust the AUDIO OUT level by referring to the Audio Pass-Through Level paragraphs in this

section.

Audio In

The audio in is provided for music on hold or for voice menu selections if connected. If the audio

volume is too low or too high, the audio in level needs to be adjusted. Increase or decrease the audio

in pass-through level (gain) from the AXB-DTMF+. The AUDIO IN pot is located about mid-center

on the AXB-DTMF+ circuit board (see FIG. 1). Perform these steps to adjust the audio in level.

1. Remove the AXB-DTMF+ cover from the unit housing. Then, apply an audio signal (1 V p-p

maximum) to the AUDIO IN connector.

2. Listen on-line and use a small flat-blade screwdriver to turn the pot counter clockwise to

reduce audio level from AUDIO IN. Turn the pot clockwise to increase the AUDIO IN level.

3. Re-install the AXB-DTMF+ cover onto the unit housing.

Audio Out

The AUDIO OUT jack provides a means of routing line level signals, which originates on the

telephone line to an external device such as a sound card.

Cables and connectors for telephone and audio hook-up are not included with the

AXB-DTMF+.

If audio is connected to the AXB-DTMF+, make sure the audio is turned on by using

the correct Send_Commands. Refer to the Axcess Programming section.

To prevent "howling", make sure that the AXB-DTMF+ AUDIO IN and AUDIO OUT

lines are not looped back through an external device.

Configuration and Installation

6AXB-DTMF+ DTMF+ Interface

Testing the AXB-DTMF+

Follow these steps to test the AXB-DTMF+:

1. Disconnect AXlink power.

2. Remove the cover from the unit housing and set the AUTO ANSWER jumper to AUTO ANSWER

ON then reinstall the cover on the unit housing.

3. Reconnect AXlink power. The status LEDs should blink in sequence from right to left and the

AXlink green LED should be blinking.

4. Place a call to the AXB-DTMF+ from an outside line.

5. The RING LED should light with an incoming ring.

6. The OFF HOOK LINE LED should light after 1 ring.

7. The DTMF RX LED should light when tones are sent from the calling telephone.

8. Check line quality and operation using an extension telephone connected to the PHONE jack.

9. Return the AUTO ANSWER jumper to OFF position, if desired.

Off-hook line and off-hook phone troubleshooting

The off-hook line and off-hook phone LEDs light only if there is a good telephone line connection.

If either the off-hook line or off-hook phone LED fails to light, a faulty telephone line connection is

indicated.

Make sure a proper phone line connection exists to light both off-hook and extension off-hook

LEDs. Test the off-hook line by following these test procedures:

1. Take the AXB-DTMF+ off-hook by issuing the off-hook Send_Command from the central

controller. If there is a good telephone line connection, then the OFF HOOK LINE LED lights.

2. If the OFF HOOK LINE LED fails to light, then there is a bad or faulty telephone line

connection. Check the incoming telephone line and make sure it is working properly. Then,

check the RJ-11 cable and its connection to the AXB-DTMF+.

Test the off-hook phone using the following steps:

1. Take the receiver off the extension telephone. If there is a good telephone line connection, then

the EXTENSION OFF HOOK LED lights.

2. If the OFF HOOK PHONE LED fails to activate, make sure that an extension off-hook

Send_Command has not been issued (you can do a Send_Command extension on-hook to be

sure; see the Operative Send_Commands section on page 7 for details). If this does not

produce results, then there is a faulty telephone line connection. Check the incoming telephone

line and make sure it is working properly. Then, check the RJ-11 cable and its connection to

the AXB-DTMF+. Make sure the RJ-11 cable from the extension telephone is good.

The extension telephone is optional and supplied by the user.
