INTEGRATING THE EF2201 INTO YOUR SYSTEM INTEGRATING THE EF2201 INTO YOUR SYSTEM Operating the EF2201 The EF2201 can be operated in two ways: through the LCD menu on the front panel or through RS-232. For control via RS-232, please refer to the EF2201 Programming Guide, which includes programming tips as well as the EF2201 RS-232 commands. For operation using the PC control software, Conference Composer, please refer to the Conference Composer User Guide.
THE EF BUS THE EF BUS The EF Bus is a high speed, low delay digital bus that includes the W, X, Y, and Z audio busses, the P bus, as well as the echo canceller bus reference and remote control information (for other EF devices). On the EF Bus page in Conference Composer, the inputs coming in to each submatrix labelled WB0, WB1, ... WB7 correspond with the device ID of the bus that is transmitting. The “B” denotes Bus.
THE EF BUS Figure 6. EF2201 P submatrix and W, X, Y, and Z submatrices. Note. The EF Bus must be connected so that the EF BUS OUT of one Vortex device is connected to the EF BUS IN of another Vortex device. Connecting EF BUS IN to another EF BUS IN (or EF BUS OUT to EF BUS OUT) will not work. See“Connector Pinouts” on page 31 for pinout of Cat 5 cable. PRESETS After configuring your EF2201, save your settings to a User Preset (PRESETS 16-47).
LCD MENU STRUCTURE LCD MENU STRUCTURE LCD Menu Tree The EF2201 LCD menu structure is made up of seven menu trees: SYSTEM, PHONE CONTROL, INPUTS, OUTPUTS, PARAMETRIC EQ, PRESETS, and MACROS. Each menu tree is organized by levels and branches into multiple subcategories. The branches end with an adjustable parameter or value.
LCD MENU STRUCTURE adjusted — you should hear changes as the parameter is changing. RS-232 control strings are also sent via the RS-232 port so your remote control device is instantaneously updated as well. Press ENTER to select and store the parameter value or press ESC to cancel the selected value and return to the old value. Pressing HOME has the effect of pressing ESC then HOME, so the selected value will be cancelled and the menu will return to the top of the menu tree.

Output Settings Output T Phone Output Gain Mute Output Delay Enable Delay The default setting is 0 dBu. Though the EF2201 allows for positive output gain, you should always try to adjust input gains to a good level so that the output gain is 0 dB.
LCD MENU STRUCTURE PARAMETRIC EQ MENU The input equalizer is comprised of up to 5 bands of filtering. The whole group of filters for the channel can also be enabled/disabled without losing the settings for each band. For each band, you first select the type of filter from the following: Parametric/ Peaking, High Shelf, Low Shelf, Lowpass, or Highpass.

TROUBLESHOOTING TROUBLESHOOTING RESIDUAL ECHO If there is residual echo in the system, it may not be a problem with the EF2201. There are different types of echoes that come from different directions, and the EF2201 is only designed to remove one of them. The first step is to make sure the echo isn’t caused by something else. Then, the EF2201 can be adjusted to remove any residual echo coming from the hybrid.
TROUBLESHOOTING Try Dialing Manually If the analog telephone works on the line, try using it with the EF2201 to dial manually. Connect the LINE jack of the EF2201 to the telephone jack in the wall, and connect the handset to the PHONE jack. Try making a call. Fix the Remote Control If you can make calls by dialing with the analog handset, but not with the remote control device, that means there is a problem with the remote control. See the “Remote Control Problems” section below.

DEFINITION OF TERMS DEFINITION OF TERMS Acoustic Echo Acoustic echo occurs in a conferencing or distance learning system when the remote speech played in the loudspeakers is picked up by microphones in the room and is transmitted back to the remote end. This transmitted signal is a delayed version of the original, which causes the echo. Acoustic Gain Acoustic gain is a term used in conjunction with sound reinforcement.
DEFINITION OF TERMS Equalization Equalization is the process of adjusting frequency characteristics of an audio signal. Line Echo Line echo is caused by reflections of the audio signal from the telephone hybrid. The EF2201 is an example of a device that includes a line echo canceller. Macros An arbitrary set of commands that can be replayed. Matrix Mixer A matrix mixer allows you to choose which inputs are included in each output. Some matrix mixers allow you to assign crosspoint gains to the inputs.
