  • Page 5: Introduction

    8.114. TONER -- Enable or Disable Ring Tones 1. Introduction This document describes the command protocol that is used to communicate with the Vortex EF2201 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.

  • Page 6: Using Acknowledgements

    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 a Vortex device will send an acknowledgment for each command it receives.

  • Page 7: Macros And Presets

    Command Data Command Terminator 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. Section 7 for a list showing all the commands and which are saved to commands.

  • Page 8: Device Id

    Device ID '**' can be used to send a command to all device IDs simultaneously. Some examples of using wildcard characters are given below. 'T**' broadcasts to all EF2201 devices that are linked together. '*07' broadcasts to all devices with device ID 07 (this format is not commonly used).

  • Page 9: Status Messages

    IDs 3 and 7. The EF2201's will respond with 'T03GAINIT10' and 'T07GAINIT10', respectively. Now, someone uses the front panel of the EF2201 set to ID 7 to decrease input T's gain by 1 dB. When this happens, the EF2201 will respond with 'T07GAINIT9'. 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.

  • Page 10: Integer Commands

    Parameters associated with boolean commands can be queried using the '?' character. For example, if input T is muted, and you send ' T04MUTEIT?', the EF2201 will respond with a status message of ' T04MUTEIT1'. 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.

  • Page 11: Matrix Commands

    Using the wildcard character for channel commands is not common on the EF2201, since it has only one input channel and one output channel. The wildcard character for channel commands is generally more useful on devices with multiple inputs, such as the EF2280 and EF2241.
  • Page 12 The EF2201 has only one physical input. This input comes from the telephone interface, and is labeled T. The T input has signal processing which includes the following algorithms: Line Echo Cancellation, Noise Cancellation, and AGC. Vortex devices can be linked together so that they can share control information and digital audio signals.
  • Page 13 Y Submatrix Inputs: YB0-YB7 Outputs: YM0-YM2 Z Submatrix Inputs: ZB0-ZB7 Outputs: ZM0-ZM2 For the P signal, bus there is a 7 x 2 matrix that allows the user to define up to two mixes of the P signal bus. The reason the matrix is 7 x 2 instead of 8 x 2 is that since we can transmit on the P bus, we do not need to mix our own channels in this matrix.

  • Page 14: Miscellaneous Commands

    'T04MMUTET,*,10' sets the mutes for input T of the main matrix. The signal path from input T to output T muted, while the signal path from input T to output P is unmuted. The EF2201 will respond with a status message of 'T04MMUTET,*,10'.

  • Page 24: Bldata -- Request Level Information

    BLDATA 8.12. BLDATA -- Request Level Information This command is used to request "blinking light" data from the EF2201. Blinking light data consists of signal levels for the 1 inputs (T) and 1 output (T). The blinking light data can be received in two ways. The first way is by polling the Vortex by sending a BLDATA? command.

  • Page 25: Blinfo -- Select Information To Be Reported In Bldata

    In the above description, the data in the BLDATA command consists of 2 bytes (1 input level + 1 output level). It is possible to tell the EF2201 to only send a subset of this information. Depending on your control system, this could make parsing the data easier since you can ask for only the data that you are interested in.

  • Page 26: Broada -- Broadcast Commands To Other Connected Devices

    8.15. 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 ' T01BROADA: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.

  • Page 43: Lid -- Assign Action For When Logic Input Is Deactivated

    T01LIA4,? 8.44. LID -- Assign Action for when Logic Input is Deactivated This function assigns a single command to be executed when a given logic input changes from the active state to the inactive state. Typically, the inactive state is logic high ('1') and the active state is logic low ('0').

  • Page 44: Lien -- Enable Automatic Logic Input Status Messages

    is commonly referred to as active low. Acitve low is considered normal because a closed switch would ground the input and a closed switch would normally be considered active. This polarity setting can be changed via the command. A single command can be assigned to each of three conditions occurring on the logic pin: a change to the active state, a change to the inactive state, and a repeating command when the pin is held in the active state.

  • Page 45: Lig -- Configure Logic Input Pins Into A Group
