1. Introduction

This document describes the command protocol that is used to communicate with the Vortex EF2210 via its RS-232 port.

2. RS-232 Hardware

The communication between the Vortex and a host controller is conducted via the RS-232 port on the back panel of the Vortex. The Vortex's RS-232 port operates at the following settings:

● Bit Rate (bps): 9600 (default), 19200, or 38400

● Data Format: 8 data bits, no parity, 1 stop bit (8N1)

● Flow Control: none (default) or hardware (RTS, CTS)

Note that although the flow control setting is user selectable to none or hardware, hardware flow control must be used when updating the firmware of the Vortex. This means that while a 3-wire RS232 cable (RX, TX, GND) is acceptable for control of the Vortex, the minimum cable for updating firmware should contain 5 wires (RX, TX, RTS, CTS, GND).

3. Programming Tips

3.1. Initialization

During power up of the Vortex device or initialization of the host program, electrical fluctuations on the RS-232 lines may cause the Vortex to receive spurious data. After initialization, the host program should send a few carriage return characters (^M, ASCII 13) to the connected Vortex to flush out any spurious characters it may have received. Failure to do this could result in the Vortex ignoring the first command received after initialization.

As part of the host program initialization, the host will want to synchronize the status of its controls

with the current status of the Vortex devices that are being controlled. The host could initialize its controls to default values and then send commands to the Vortexes to set them to the same state. This approach has significant disadvantages since initializing the host program could undo settings made by other host programs or by the front panel controls of one of the linked Vortex devices. A better approach is to query the linked Vortex devices for their status and set the host program controls based on the return values.

3.2. Wildcard Characters

The use of the wildcard character, '*', can make programming the host controller much easier. Be careful when using wildcards, however, since they can generate a lot of traffic on the digital bus.

3.3. Using Acknowledgements

It is a good idea for the host program or control system to make sure that all connected Vortex devices have acknowledgment mode enabled (see the ACKMOD command). When acknowledgment

mode is on, a Vortex device will send an acknowledgment for each command it receives. Proper use of acknowledgments makes the host program more robust and makes supporting multiple hosts effortless. The rest of this section describes how to use acknowledgments to achieve these goals.

As a convenient example, let us imagine a host program with a graphical user interface (GUI). The user presses buttons on the GUI to enable or disable features of various linked Vortex devices. The buttons on the GUI reflect the current status of the corresponding feature.

When the user presses a button on the GUI to enable or disable a feature, the host program should send the corresponding command to the selected Vortex device. It may be tempting to update the status of the GUI button at this point, but this can cause problems if there are transmission errors or if there are multiple host controllers. The proper way to handle this is to only update the GUI controls based on acknowledgments received from the Vortex device.

To implement this, organize your code so that the functions that send commands are totally separate from the functions that receive responses from the Vortex devices. This also enables your host program to support the presence of multiple host controllers. For example, consider the following sequence of events.

1. Another host sends a command to a Vortex device.

2. The Vortex device responds with an acknowledgment that is broadcast to all of the other hosts.

3. Your host program receives the acknowledgment and updates the status of the corresponding control.

The result of this programming model is that all hosts and linked Vortex devices will always be synchronized.

For simple on/off features, your host program can make use of the toggle arguments to some commands (e.g., 'SSEN2'). By sending a toggle command when a button is pressed, and updating the button based on acknowledgments, your host program will not have to keep track of the status of the button.

In a similar fashion, many of the integer commands (such as gains) can be controlled by incrementing or decrementing them by a specific amount. For example, the command ' ' increments the input gain on channel by 1 dB. The acknowledgment for this command will return the actual value that the gain was incremented to. Thus, to implement a volume control, your control program can send a command to increment the gain by 1 dB when the "up" button is pressed and decrement the gain by 1 dB when the "down" button is pressed. The control can update its level indicator based on the acknowledgment that is received.

3.4. Macros and Presets

Although macros and presets are similar, there are times when using one is better than the other. Presets store the absolute values of all of the non-global settings of the device. This includes, but is not limited to, input and output gain settings, matrix settings, algorithm settings, parametric EQ settings, and automixer settings. See

saved to presets.

Presets should be used when you really want to change all the settings in a device. One example would be when you want to have one unit be able to control different rooms. In this case, having a preset for each different room is the easiest solution.

Section 7 for a list showing all the commands and which are

Macros are like mini-presets. You can define them to change only the settings you are interested in. One advantage of macros over presets is that macros can make relative changes in addition to absolute changes. An absolute change is something like "set the input gain to -3 dB". A relative change is something like "raise the input gain by 3 dB". One example of using macros for a relative change is stereo volume ramping. If you have two outputs setup to have left and right program audio, then you could build a macro that contains two commands: one to increment the left channel by 1 dB and the other to increment the right channel by 1 dB. Then, by calling that macro, you can ramp the stereo outputs. A similar thing can be done with decreasing the volume.

Another thing to consider when using macros and presets is to use the commands instead of the macro or preset, but the X versions produce acknowledgements for the settings that change, while

the Q versions don't. If your control system updates its status by looking at the acknowledgements that come back, then you'll probably want to use the X versions. Another option would be to use the Q versions and then manually query the values you're interested in. If your control system does not need use acknowledgements, or if you are manually querying the values you're interested in, using the Q versions is better since it doesn't generate acknowledgements and thus reduces RS-232 traffic.

4. Command Structure

A Vortex command consists of a series of ASCII characters with the following structure.

Description Number of Characters Range of Values

Device Type 1 Device ID 2

0-9, A-Z, * 0-9, *

Command Name 1-7 Command Data 0-64 ASCII characters

0-9, A-Z

Command Terminator 1

^M (ASCII 13)

4.1. Device Type

A single alphanumeric character is used to indicate the device type. The devices in Polycom's EchoFree family have the following device types.

Device Device Type

EF200 EF1210 EF2280 EF2241 EF2211 EF2210 EF2201

A C F B S Q T

Device type '*' can be used to send a command to all device types simultaneously.

4.2. Device ID

Two numeric characters are used to indicate the device ID. The Vortex can be configured for device IDs from '00' to '07'. Note that even though the device ID is less than 10, the leading '0' must be included. Device ID '**' can be used to send a command to all device IDs simultaneously. Some examples of using wildcard characters are given below.

● 'Q**' broadcasts to all EF2210 devices that are linked together.

● '*07' broadcasts to all devices with device ID 07 (this format is not commonly used).

● '***' broadcasts to all devices that are linked together.

4.3. Command Name

The command name can be from 1 to 7 characters long. Command names will be specific to device types. In other words, the EF2280 has its own command set, which is different from the EF2241's, which is different from the EF1210's, etc. There are some commands, such as 'PING', that are common among all the various command sets.

4.4. Command Data

The command data is a series of 0-64 characters containing payload data for the command. Obviously, the command data will be specific to the command type. note that the maximum number

of payload characters for the EF200 and EF1210 is 32, but the Vortex devices support up to 64 characters in the payload. This increase was necessary to accommodate the matrix gain and macro/preset commands.

4.5. Command Terminator

The command terminator is a single character indicating the end of a command. ASCII 13 (^M) was chosen as the terminator to allow manually typing commands using a simple text terminal.

4.6. Examples

In the following examples, Vortex commands are enclosed in single quotes, 'like this'. Also, the terminator character is not explicitly shown, but its presence is implied.

Consider the command '***PING'. The device type and ID for this command are wildcards, thus the command will be sent to all devices. The command name in this case is 'PING', and there are no data characters (payload). Note that the 'PING' command is supported by all of the Vortex devices, thus broadcasting the command to all devices makes sense.

Consider the command 'Q**GAINIA10'. The device type for this command is 'Q' and the device ID is a wildcard, thus the command will be broadcast to all EF2210 devices linked together. The command name in this case is 'GAINIA' and the command data (payload) is '10'. This command sets the gain on input A of all connected EF2210's to 10 dB.

Command Effects

***PING Q**GAINIA10

Requests PONG response from all linked Vortex devices. Sets the gain on input A of all connected EF2210 devices to 10 dB.

5. Status Messages

The Vortex sends status messages via RS-232 and EF Bus any time one of its internal parameters changes. This means that the host program does not need to continually poll the Vortex in order to detect status changes. Status messages are in the same format as the commands used to set the corresponding parameter.

For example, suppose you send the command 'Q**GAINIA10' and there are two EF2210's linked together with device IDs 3 and 7. The EF2210's will respond with 'Q03GAINIA10' and 'Q07GAINIA10', respectively. Now, someone uses the front panel of the EF2210 set to ID 7 to decrease input A's gain by 1 dB. When this happens, the EF2210 will respond with 'Q07GAINIA9'. This example illustrates that status messages can be sent as the result of an RS-232 command or as the result of some other change in the Vortex device such as front panel adjustments, logic inputs, etc.

Status messages can be turned off via the mode since the term status message and acknowledgement are synonymous for our purposes.

ACKMOD command. ACKMOD refers to acknowledgement

6. Command Types

Many of the Vortex commands have similar formats. The main formats are described here in order to provide a better understanding of the command set.

6.1. Boolean Commands

Boolean commands take one of the three following arguments.

● '0' indicates that the parameter should be turned off.

● '1' indicates that the parameter should be turned on.

● '2' indicates that the parameter should be toggled (i.e., '0' becomes '1' and '1' becomes '0').

Parameters associated with boolean commands can be queried using the '?' character. For example, if input A is muted, and you send ' Q04MUTEIA? ', the EF2210 will respond with a status message of ' Q04MUTEIA1 '. When a status message is generated for a boolean command, the command data will either be a '0' or '1', since '2' is obviously not a valid state.

6.2. Integer Commands

Integer commands can take one of two types of arguments. The first argument type is absolute, meaning that the parameter will be set to the specified number. For example, ' Q04GAINIA10 ' means that the gain on input A will be set to 10 dB. In this case, the device will respond with a status message of ' Q04GAINIA10 '.

The second argument type is relative, meaning that the parameter will be incremented or decremented by the specified amount. The increment character is '>' and the decrement character is '<'. For example, ' Q04GAINIA>3 ' increments the gain on input A by 3 dB. If the input's gain was previously set to 6 dB, then it would now be set to 9 dB. In this case the device would respond with a status message of ' Q04GAINIA9 '.

The numeric part of both the absolute and relative arguments can contain a '+' or '-' to indicate the algebraic sign of the argument. If no sign is given, '+' is assumed.

The parameters associated with integer commands have maximum and minimum values associated with them. If you try to set a parameter above its maximum or below its minimum, the parameter will be set to its maximum or minimum value, respectively.

Parameters associated with integer commands can be queried using the '?' character. For example, if input A 's gain is set to 12, and you send ' Q04GAINIA? ', the device will respond with a status message of ' Q04GAINIA12 '.

6.3. Channel Commands

A command can be a channel command in addition to being one of the other types of commands (integer or boolean). A channel command means that the command applies to a specific input or output channel. The channel is specified by a single character (e.g., '1', 'A', 'B', etc.) occurring before any other payload data.

An example of a boolean channel command is the '

AGC' (Automatic Gain Control) command. '

Q04AGC10 ' disables the AEC on input channel 1 . After sending this command, the device will

respond with a status message of ' Q04AGC10 '.

An example of an integer channel command is the 'GAINI' command, which adjusts the gain on the input channels. ' Q04GAINIA12 ' sets the input gain of channel A to 12 dB. After sending this

command, the device will respond with a status message of ' Q04GAINIA12 '.

A wildcard character ('*') can be used as the channel specifier for many of the channel commands. If this is the case, there are two options for specifying the values for the channels. The first method is to specify a single value that will be applied to all the channels.

Take the

MUTEI command for example: ' Q04MUTEI*1' mutes input channels 1 and A-B After

sending this command, the device will respond with a status message of ' Q04MUTEI*111'. In this status message, the device reports the status of all the channels. Since the MUTEI command applies to channels 1 and A-B the status of all 3 channels. The first (left most) value corresponds to channel 1 and the last (right most) value corresponds to channel B.

This leads us to the second method of using a wildcard character: specifying the values for each of the channels. For example, ' B04MUTEI*101' mutes channels 1, B and unmutes channel A. In this case, the device will respond with a status message of ' B04MUTEI*101'.

As an interesting example, consider sending ' Q04MUTEI*2' after the above example. The device will respond with a status message of ' Q04MUTEI*010'. Notice that all the states have been toggled.

Queries using the '?' character are straightforward. For example, ' Q04MUTEI1?' might return ' Q04MUTEI11', while ' Q04MUTEI*?' might return ' Q04MUTEI*100'.

Using the wildcard character with integer channel commands is similar to using it with boolean commands, but there are some differences. If we sent ' Q04GAINI*10', the input gains on channels 1 and A-B will all be set to 10 dB. The device will respond with a status message of ' S04GAINI*ÄÄÄ'. Those weird characters are the main difference between using wildcards with integer channel commands versus boolean channel commands. When reporting multiple integer values, the Vortex uses a binary format with one byte per integer value. This allows for more compact commands and reduces RS-232 and bus traffic. To convert from an integer value to a byte value, we add 132 to the integer value. In the above example, where the gain is set to 10 dB, we have: 10 + 132 = 142 = 0x8E (hex) = Ä (ASCII). The reason for adding 132 is to allow us to conveniently represent negative numbers as well as avoid the use of special characters that are normally used in RS-232 and EF Bus communications.

When using a wildcard character to specify separate values for each channel, you must also use the binary format. For example, ' Q04GAINI*Äää' sets the input gain of channel 1 to 10 dB and the input gain of channels A-B to 0 dB. (10 + 132 = 142 = 0x8E (hex) = Ä (ASCII), 0 + 132 = 132 = 0x84

(hex) = ä (ASCII))

As an interesting example, consider sending ' Q04GAINI*>3' after the above example. This will result in all the input gains being incremented by 3 dB so that channel 1 is at 13 dB and channels A-B are at 3 dB. The Vortex will respond with a status message of ' Q04GAINI*æçç'. (13 + 132 = 145 = 0x91 (hex) = æ (ASCII), 3 + 132 = 135 = 0x87 (hex) = ç (ASCII))

Queries using the '?' character are straightforward. For example, ' Q04GAINI1?' might return ' Q04GAINI110', while ' Q04GAINI*?' might return ' Q04GAINI*Äää'.

6.4. Matrix Commands

Matrix commands are used for controlling parameters that exist at the crosspoints of the mixing matrices. Typical parameters include gain and mute. Before describing the matrix commands, it is necessary to give a description of the matrices involved. During the following discussion, it will be helpful to refer to the figure below, which shows all the matrices with their input and output labels.

The EF2210 has three analog outputs labeled 1, A, and B. These outputs are all at line level. This yields a total of three physical outputs. The EF2210 also has a power amplifier output, however the power amplifier does not have a separate output in the matrix -- it is tied to output 1. Thus the signal routed to output 1 will also be routed to the power amplifier output.

The EF2210 has three analog inputs labeled 1, A, and B. Input 1 is mic/line selectable, and inputs A-B are line level only. Input 1 can also have phantom power enabled and contain channel processing, which includes the following DSP algorithms: Acoustic Echo Cancellation, Noise Cancellation, and AGC. Inputs 1, A, and B yield a total of three physical inputs.

Vortex devices can be linked together so that they can share control information and digital audio signals. The audio signals are shared on four digital busses labeled P, W, X, Y, and Z. All Vortex devices can receive signals from all of these busses. Only certain devices can transmit on the busses. This information is given in the following table.

Device Transmit on P Bus

Transmit on W, X, Y, Z Busses

Receive P Bus

Receive W, X, Y, Z Busses

EF2280 No Yes Yes Yes EF2241 Yes Yes Yes Yes EF2211 Yes Yes Yes Yes EF2210 No Yes Yes Yes EF2201 Yes No Yes Yes

The P bus is meant for routing telephone audio between the devices. The W, X, Y, and Z busses are meant for routing microphone and auxiliary audio between the devices. The W, X, Y, and Z busses also carry NOM (Number of Open Microphones) information from the automixer so that outputs created from these busses can be appropriately attenuated for the number of open microphones.

The digital inputs consist of all of the signals placed on the EF Bus by the other connected Vortex devices. Each P, W, X, Y, and Z bus can carry channels from up to eight other devices, so we have the following digital inputs to each Vortex device: PB0-PB7, WB0-WB7, XB0-XB7, YB0-YB7, and ZB0ZB7. The inputs are designated by three characters: the bus letter (P, W, X, Y, or Z), a B indicating that it is a bus input, and a number between 0 and 7 indicating the channel of the bus.

There is also an internal signal generator, labeled SG, that is capable of producing white or pink noise. this signal is fed into the matrix so that it can be routed to the appropriate outputs for calibration or testing.

The mixing capabilities of the Vortex devices can be broken down into two parts: the EF Bus submatrices and the main matrix.

For each of the W, X, Y, and Z signal busses, there is a 7 x 3 matrix that allows the user to define up to three mixes of each of the four signal busses. The reason the matrix is 7 x 3 instead of 8 x 3 is that since we can transmit on the W, X, Y, and Z busses, we do not need to mix our own channels in

these matrices. The inputs and outputs for the 7 x 3 matrices are as follows.

W Submatrix

● Inputs: WB0-WB7 (with one invalid)

● Outputs: WM0-WM2

X Submatrix

● Inputs: XB0-XB7 (with one invalid)

● Outputs: XM0-XM2

Y Submatrix

● Inputs: YB0-YB7 (with one invalid)

● Outputs: YM0-YM2

Z Submatrix

● Inputs: ZB0-ZB7 (with one invalid)

● Outputs: ZM0-ZM2

For the P signal bus, there is an 8 x 2 matrix that allows the user to define up to two mixes of the P signal bus. This matrix has a full 8 inputs since the EF2210 does not transmit on the P bus. The inputs and outputs for the 8 x 2 P bus matrix are as follows.

P Submatrix

● Inputs: PB0-PB7

● Outputs: PM0-PM1

The crosspoint gains on all outputs are user adjustable. The "M" in the output labels of the submatrices indicates that the signals are being fed into the Main Matrix.

The main matrix consists of the following inputs: analog inputs 1, A, and B, the signal generator (SG), the outputs of the EF Bus submatrices PM0-PM1, WM0-WM2, XM0-XM2, YM0-YM2, and ZM0-ZM2. This is a total of 18 inputs.

The main matrix consists of the following outputs: analog outputs 1, A, and B, AEC reference signal R1, and the EF bus outputs W, X, Y, and Z. This is a total of 8 outputs.

The matrix commands can adjust two types of parameters: integer and boolean. We will introduce the matrix commands by using the MGAIN command as an example. This is an integer matrix command that is used to set the gain (in dB) at any of the crosspoints in the main matrix or EF Bus submatrices.

Matrix commands are similar to channel commands except that instead of specifying a single channel, it is necessary to specify a crosspoint (or range of crosspoints). In order to specify a single crosspoint, you use the input and output labels discussed in this section. The first label always specifies the input

to the matrix and the second label always specifies the output of the matrix. For example, to set the gain of the crosspoint (1, A) to -3 dB, you would send ' Q04MGAIN1,A,-3 ' which sets the gain at the crosspoint to -3 dB. In this case, a status message will be generated similar to ' Q04MGAIN1,A,- 3 '.

It is also possible to use the wildcard character ('*') to specify ranges of crosspoints with the matrix commands. The only restriction is that you can only use a wildcard to specify the input or output, but not both simultaneously. Thus you could specify all the inputs going to a specific output (one column) or the value of an input to all of the outputs (one row), but not the entire matrix. One example of using a wildcard for an integer matrix command would be ' Q04MGAINSG,*,0 '. This will set all the crosspoints in the signal generator row of the main matrix to 0 dB. Thus, the signal generator will be added to all of the outputs of the main matrix with a gain of 0 dB. In this case a status message will be generated that looks like ' Q04MGAINSG,*,дддддддд '. The binary representation used here is the same method described in

Section 6.3.

You can also use the wildcard character to set the crosspoints of a row or column individually. For example, 'Q04MGAIN1,*,äzzxxxxx' sets the crosspoints of input 1 to 0 dB for output 1, -10 dB for outputs A and B, and -12 dB for outputs R1, and W-Z. In this case, the EF2210 will respoind with a status message of 'Q04MGAIN1,*,äzzxxxxx'.

Queries using the '?' character work in the usual manner. For example, ' Q04MGAIN1,A,? ' might return ' Q04MGAIN1,A,-6 ', while ' Q04MGAIN1,*,? ' might return ' Q04MGAIN2,*,дддддддд '.

Boolean matrix commands work as you would expect. They use the characters '0', '1', and '2' as described in

● ' Q04MMUTE1,A,1 ' mutes crosspoint (1, A) of the main matrix. In other words, the signal at

Section 6.1. Here are some examples.

input 1 will not be heard on output A A status message will be generated of the form ' Q04MMUTE1,A,1 '.

● 'Q04MMUTEA,*,11100000' sets the mutes for input A of the main matrix. The signal path

from input A to outputs 1, A, and B is muted, while the signal path from input A to outputs R1 and W-Z is unmuted. The EF2210 will respond with a status message of 'Q04MMUTEA,*,11100000'.

● 'Q04MMUTEA,*,2' toggles the mutes for input A of the main matrix. If this command follows

after the command in the above example, the EF2210 will respond with a status message of 'Q04MMUTEA,*,00011111'.

● 'Q04MMUTEA,*,?' queries the status of the mutes for input A of the main matrix. If this

command follows after the commands in the above examples, the EF2210 will respond with a status message of 'Q04MMUTEA,*,00011111'.

6.5. Miscellaneous Commands

Miscellaneous commands are those that don't fall under any of the other categories. See the description of a given command for specific details on how it operates.

7. Command List

The following table is a list of the commands recognized by the EF2210 Detailed descriptions of each command are given in the next section.

The Storage column contains one of the following values indicating when and where the parameter is stored.

● "Global"

● "Preset"

● "-" = not stored or not applicable

Globally stored parameters are not changed when a preset is executed. Only one copy of a global parameter is stored. Global parameters are written to non-volatile memory each time they are changed. Globally stored parameters retain their values when the power is cycled.

Parameters stored in presets are changed each time a new preset is restored/executed. Preset parameters are not saved in non-volatile memory until a

stored in the power-on preset (see

PRESETP) are restored when the power is cycled.

8.10. AMBUSID -- Set Automixer Groupings for EF Bus

This command is used to assign the internal automixer to one of the EF Bus automixer groups. For example, consider three EF2210's, each of which has its automixer enabled for its microphone input (input 1). Now, if each of these EF2210's sets its automixer to have Bus ID 5, then the three automixers (one from each EF2210) will work as a single automixer containing 3 (3 x 1) microphones. Setting AMBUSID to 0 means that the specified automixer is not grouped on the bus. For compatibility with EF2280 and EF2241 commands, the AMBUSID command requires you to specify the automixer number with the command. On the EF2280 and EF2241, there are two internal automixers. However, the EF2210 only has one internal automixer, so 1 is always specified.

The first argument in the AMBUSID command is the automixer number (always 1 for the EF2210) and the second argument is the Bus ID (0 for none, or 1 through 8). Although this command is a channel integer command, use of the wildcard character for the automixer number is not supported.

This command is a channel integer command. See

Section 6.3 and Section 6.2 for more information

on this type of command. The minimum and maximum values for this command are 0 and 8, respectively.

8.29. BLDATA -- Request Level Information

This command is used to request "blinking light" data from the EF2210. Blinking light data consists of signal levels for the 3 inputs (1, A, B), 3 outputs (1, A, B), and AEC reference (R1) as well as the room gain level for input 1, AGC gain level for input 1, and AEC state information for input 1.

The blinking light data can be received in two ways. The first way is by polling the Vortex by sending a BLDATA? command. The second way is to have the Vortex automatically send BLDATA responses via the

The most general format of the BLDATA responses generated by the Vortex is as follows.

Q01BLDATAiiiooorgas

BLAUTO command.

Each of the i, o, r, g, a and s characters above represents a single byte of data as shown in the table below.

BLDATA Bytes

iii ooo r g a s

Each of the i bytes correspond to signal levels on the 3 inputs in the following order (from left to right): 1, A, B. The o bytes correspond to signal levels on the 3 outputs in the following order (from left to right): 1, A, B. The r byte indicates the signal level for AEC reference R1. The the g byte indicates the room gain for input 1. The a byte indicates the AGC gain on input 1. The s byte indicates the AEC state for input 1.

Meaning

input levels 1, A, B output levels 1, A, B AEC reference level R1 room gain 1 AGC gain 1 AEC state 1

The formats of the i, o, r, g, and a bytes are the same as for the binary gain commands (binary values offset by 132). See

The range for the i and o bytes is -100 dB to +20 dB, which corresponds to byte values of 32 to 152. For reference, the LEDs on the front panel signal meter correspond to teh following dB levels (left to right): -20, -12, -7, -3, 0, 3, 9, 20.

The format of the s bytes are also the same as the binary gain commands. The bytes are integers (offset by 132) that represent the current AEC state. The following table shows how the byte values

Section 6.3 and Section 6.4 for more information on the binary format.

translate to AEC states.

Byte Value AEC State Value (Byte Value - 132) AEC State Description

132 0 Idle 133 1 Transmit 134 2 Receive 135 3 Double Talk

Here's an example BLDATA message to clear things up.

Q01BLDATApèpçppppèä

The first three bytes (pèp) consist of only two values.

p = 0x70 = 112 → 112 - 132 = -20 è = 0x8A = 138 → 138 - 132 = 6

So, the signal at input A is at 6 dB, while the signals at the rest of the inputs are at -20 dB.

The next three bytes (çpp) consist of only two values.

p = 0x70 = 112 → 112 - 132 = -20 ç = 0x87 = 135 → 135 - 132 = 3

So, the signal at output 1 is at 3 dB, while the signals at the rest of the outputs are at -20 dB.

The next byte (p) consists of only one value.

p = 0x70 = 112 → 112 - 132 = -20

So, the signal level of the AEC reference is -20 dB.

The next byte (p) consists of only one value.

p = 0x70 = 112 → 112 - 132 = -20

So, we know that the room gain for input 1 is -20 dB.

The next byte (è) consists of only one value.

è = 0x8A = 138 → 138 - 132 = 6

So, we know that the AGC gain for input1 1 is 6 dB.

The last byte (ä) consists of only one value.

ä = 0x84 = 132 → 132 - 132 = 0 = Idle

So, we know that the AEC on input 1 is in idle mode.

In the above description, the data in the BLDATA command consists of 10 bytes (3 input levels + 3 output levels + 1 AEC reference level + 1 room gain level + 1 AGC gain level + 1 AEC state). It is possible to tell the EF2210 to only send a subset of this information. There are two reasons you might want to do this. First, it makes parsing the data easier since you can ask for only the data that you are interested in. Second, when you decrease the amount of data being sent, the EF2210 can send the messages faster. This means that if you are trying to implement a signal level meter, you can get faster refresh rates by asking the EF2210 to only send the data you're interested in.

Suppose you were only interested in signal levels on inputs A-B. You could send the following command.

Q01BLINFO0110000000

In the above positions of the data that we don't want. Now, when we send a BLDATA? command or enable

BLAUTO, the Vortex sends messages of the form:

Where the ii bytes are the signal levels for inputs A-B.

8.31. BROAD2 -- Broadcast Arbitrary Command Strings to RS-232 Port

This command is used to broadcast arbitrary commands to the RS-232 port for controlling other devices (not necessarily other Vortex devices). For example, ' ' ' ' Q01BROAD2:ATDT4048921180' ' would cause the Vortex to send out 'ATDT4048921180' via its RS-232 port. If a modem was

connected to the RS-232 port, this command would cause the modem to dial the Polycom Installed Voice Business Group in Atlanta.

Q01BROAD2

8.32. BROADA -- Broadcast Commands to Other Connected Devices

This command is used to broadcast commands to other connected Polycom devices via the EF Bus and/or ASPI Bus. For example, the command ' Q01BROADA:B02PHONE1 ' would cause device ID 1 to send a command to the EF2241 at device ID 2 to tell it to take its phone off-hook. The EF2241 at device ID 2 would respond by taking its device off-hook and sending an acknowledgement.

This command is usually used in macros when one needs to have a macro on one device trigger an action on another device.

Example Description Status Message

Q01BROADA

Q01BROADA:B02PHONE1

B02PHONE1, this second status message is from the EF2241 at device ID 2 when it takes its phone off hook.

8.33. BUSREF -- Set Which AEC Reference is Placed on EF Bus

This command sets or queries whic AEC reference (if any) is placed on the EF Bus. Setting BUSREF to '0' means that no reference is placed on the EF Bus. Setting BUSREF to '1' means that AEC reference 1 (R1) is placed on the bus.

Only one Vortex can put a reference on the EF Bus at a time. If more than one Vortex places its reference on the EF Bus, then an 'ERROR#093' will occur.

This command is an integer command. See command. The minimum and maximum values for this command are 0 and 2, respectively.

8.34. CGATE -- Query Camera Gating Status Information

This command is used to query the gating status of the microphone input. It is identical to the GATE command except that any given microphone must be gated on for a specified hold time in order for it

to be considered "on" by the CGATE command. A typical use for this command is to control camera pointing based on microphone activity. The added hold time prevents the camera from jumping too quickly between positions when there are short amounts of signal present.

The

CGATET specifies the hold time used for the gating decisions in this command. The CGATEEN can

8.60. MACROA -- Add Command to Current Macro

This command adds a command to the macro currently in progress. This is used in conjunction with the MACROS and MACROW commands to create a new macro.

The syntax of this command specifies a macro number, a comma, and then the command to be added to the macro. The command to be added to the macro can be any valid command except the following:

● any PRESET command

● any MACRO command

● any logic input or output command

If an attempt to assign an invalid command to a macro is made (via condition ERROR#074 will be generated.

An error will be generated if the specified command is not a valid command. However, an error will not be generated if the specified command is valid, but its data is invalid. For example:

Q01MACROA25,LAYDOWNTHEBOOGIE

Would return an error because it does not contain a valid command. However:

Q01MACROS112 Q01MACROA112,MUTEI*0 Q01MACROA112,GAINI*0 Q01MACROA112,MUTEO*0 Q01MACROW112

This defines macro number 112 to unmute all inputs, set all input gains to 0 dB, and unmute all outputs. It is acceptable if another command is sent in between these commands (such as Q01NC*? ) as long as it isn't another non-volatile memory command which could interfere with the storage of the macro.

8.61. MACROK -- Delete One or All Macros

This command kills (deletes) the specified macro. If the wildcard character (*) is used the specify the macro number, then all macros are deleted. Deleting all macros via MACROK* is more efficient than deleting them all individually since it requires less writes to non-volatile memory.

This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it is changed. It will retain its value after power-down. Since this command writes to nonvolatile memory, there will be a delay before an acknowledgment is returned.

This includes global parameters, presets, macros, labels, and logic assignments. The lock applies whether the user tries to make the changes via RS-232, front panel, logic inputs, or any other method. The user will still be able to query all the features of the device, but will get an error message if an attempt is made to change them. When NVLOCK is disabled, the user has full access to the system settings.

Usage of this command is similar to other boolean commands (see disabling this feature, the password must be supplied for the command to work. If an incorrect

password is supplied, 'ERROR#005' will be generated. The examples below illustrate the correct usage. The examples assume that the password has been set to 'aspi' (the default). The NVLOCK password can be changed via the

NVPSWD command.

8.98. PRESETK -- Delete One or All Presets

This command kills (deletes) the specified preset. If a wildcard character (*) is used to specify the preset, then all presets are deleted.

If an attempt is made to delete one of the factory presets (in the range 0-15), the PRESETK command will fail and generate an ERROR#071. This is because the factory presets are read-only, thus the cannot be changed or deleted.

This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it is changed. It will retain its value after power-down. Since this command writes to nonvolatile memory, there will be a delay before an acknowledgment is returned.

8.104. REFASGN -- Assign AEC Reference to Input Channel

This command assigns an AEC reference signal (R1 or EF Bus) to an input channel. Only input 1 has echo cancellation, so the command is only valid for that channel. Assigning 1 to the input channel selects AEC Reference 1 (R1). Assigning 3 to an input channel selects the EF Bus Reference. The EF Bus reference is an AEC reference that is placed on the EF Bus by one (and only one) of the linked Vortexes. See the

REFASGN a value of 2 is not supported on this device. The value of 2 is only supported on devices that can build a second AEC reference (i.e., the EF2280, EF2241).

8.105. REFGAIN -- Set Reference Output Gain

This command sets the effective output gain of the corresponding AEC reference. When doing volume control of room speakers, it is a good idea to adjust this reference gain along with the speaker output gain so that the AEC is aware of any volume changes. This will help prevent short echoes when volume changes are made.

There are two AEC references on the EF2280, EF2241, and EF2241, so there are two separate commands, REFGAINR1 and REFGAINR2, for controlling the effective output gain of R1 and R2, respectively.

There is only one AEC reference on the EF2211 and EF2210, so there is only one command, REFGAINR1 for controlling the effective output gain of R1.

This command was introduced in firmware version 2.5.0.

This command is an integer command. See command. The minimum and maximum values for this command are -100 and 20, respectively.

This command is saved to non-volatile memory only as part of a preset. The state of this command will be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
