• Definition of Terms explains terms used in this manual, as well as terms used in

our technology of echo cancellation, noise cancellation, and audio conferencing.

About the EF2201 The Vortex EF2201 is the next generation of “digital hybrid” telephone interfaces. It

features a complete digital interface to other Vortex products using the digital expansion bus. The EF2201 interfaces telephone audio to the Vortex family of products and allows up to 8 callers to be added to the same conference by using 8 EF2201s.

Telephony signals are communicated with Vortex devices over the digital “P-bus” channel of the EF Bus without the need for an analog input and output. The EF2201 can be controlled via RS-232, Vortex Expansion bus, and via the front panel controls.

The EF2201 has audible ring indications, user configurable entry and exit tones, and controllable levels of DTMF and dialtone signals. The EF2201 settings are configured using the Conference Composer software and can be stored as user presets within the EF2201.

The EF2201 connects directly to an analog (PSTN) telephone line, connecting an outside caller to your meeting. In addition to providing crystal-clear telephone audio to all participants, the EF2201 significantly reduces background noise coming in on the telephone line to keep unwanted sounds from interfering with your conference.

OUNTING THE

Recommendation For Easy Access

Instructions for Securing Power Supply to Back of EF2201

CAUTION-To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.

EF2201

The EF2201 can be mounted in a rack enclosure using four large screws (10-32x1/2”) included with the unit. One EF2201 fits in a single rack space.

While not required, leave a single rack space in between the EF2201 and other units in your rack. This gives you easier access to the back panel.

• Locate the cable clamp on the back panel of the EF2201 above the power connector.

• Remove the screw and thread the power cord through the cable clamp.

• Attach the cable clamp to the back panel of the EF2201 and tighten the screw. Align the clamp so that the power cable does not interfere with the connectors on the EF2201 back panel.

• Plug in the power supply.

• We recommend that you also Ty-wrap the power supply to the rack. The purpose of securing the power supply to the back panel is so that if the power supply were to drop, it would pull where the cord is attached with the cable clamp and not pull the plug out of the EF2201.

Caution! Do not use any other power supply other than the one pro-

vided with this unit.

INSTALLATION

The following steps are typically used to set up the EF2201:

• Connect the EF B tion will provide both audio and remote control information to and from the Vortex device.

• Connect the L

• Connect the P

• Connect the external power supply to the P EF2201.

• Set the country code on the EF2201. By default the phone interface will be disabled until you select a country code for the telephony interface. This can either be done with the front panel LCD menu, or the RS-232 interface. The country code only needs to be selected the first time or when the country of the installa-

tion is changed.

NOTE The country code must be selected in order to begin using

ONNECTING

ULTIPLE

When considering which Device IDs can be used for which Vortex device, decide how many devices have the ability to transmit on the W, X, Y, and Z busses, and how many have the ability to transmit on the P Bus. The EF2201, for example, can only transmit on the P bus while the EF2241 can transmit on the W, X, Y, Z and P busses and the EF2280 can only transmit on the W, X, Y, and Z busses. Up to 8 devices can transmit on the W, X, Y, and Z busses. Similarly, up to 8 devices can transmit on the P bus. Note that the EF2241 counts as one of both types. All devices that can transmit on W, X, Y, and Z must have unique device IDs and all devices that can transmit on P must have unique device IDs.

EF2201s and EF2241s must have unique device IDs since both can transmit on the P Bus. EF2280s and EF2241s must have unique device IDs since both can transmit on the W, X, Y, and Z busses. If the device IDs of linked Vortex devices that can transmit on the same busses are the same, the front panel LCD screen will display “EFBus Error: Dev. ID Conflict”.

EF2201 D

Up to 8 EF2201 devices in combination can be linked together at one time (See Device IDs on the EF Bus above). Each unit in the chain must have a unique Device ID. Use the EF Bus to link multiple EF2201s together.

The following steps should be followed to connect the EF Bus:

1. Set a unique Device ID for each EF2201. The Device IDs range from 00 to 07.

2. Power off all units.

3. Connect the RS-232 remote control device to any EF2201 in the chain.

4. Connect the provided Cat-5 cable between the EF B

and the EF BUS IN of the second device.

Note. The EF Bus must be connected so that the EF Bus In of one

box is connected to the EF Bus Out of another. Connecting the EF Bus In to another EF Bus In (or Out to Out) will not work.

The EF2201 is self-terminating so if you are connecting multiple EF2201s or connecting an EF2201 to an EF2241, the EF Bus does NOT need to be terminated. However, if you are linking the EF2201 to EF2280s, terminate the EF Bus link on the EF2280.

ACTORY DEFAULT SETTINGS

The following is a list of the factory default settings of the EF2201. Since the equipment in your application may have different nominal levels, you can start with a F

TORY PRESET (Presets 0-15), change it to match your environment and then save it

within the EF2201 as a U P

Check Levels to the Acoustic Echo

If you have multiple devices in your system, save settings to a user preset (Presets 16-

47) on each device. Saving a preset will only save the preset on that particular unit.

Also, remember to set the P your settings to otherwise the device will revert back to Preset 0 (factory default) if power is lost.

If you are connecting the EF2201 to a Vortex device, the default level of 0 dB should give sufficient gain.
