    8.116. VTXMODO -- Enable VTX Mode on Specified Inputs 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.

  • Page 6: Wildcard Characters

    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.

  • Page 7: Macros And Presets

    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.

  • Page 8: Device Type

    Command Name 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. Device EF200 EF1210 EF2280 EF2241 EF2211 EF2210 EF2201 Device type '*' can be used to send a command to all device types simultaneously.

  • Page 9: Command Terminator

    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.

  • Page 10: Command Types

    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.
  • Page 11 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.

  • Page 12: Matrix Commands

    (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.
  • Page 13 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.
  • Page 14 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.

  • Page 15: Miscellaneous Commands

    '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'.
