    8.155. VTXMODO -- Enable VTX Mode on Specified Inputs 1. Introduction This document describes the command protocol that is used to communicate with the Vortex EF2211 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 7: 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 mode is on, a Vortex device will send an acknowledgment for each command it receives.

  • Page 8: Macros And Presets

    "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.

  • Page 9: Device Id

    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 10: Examples

    Consider the command 'S**GAINIA10'. The device type for this command is 'S' and the device ID is a wildcard, thus the command will be broadcast to all EF2211 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 EF2211's to 10 dB.

  • Page 11: Boolean Commands

    Parameters associated with boolean commands can be queried using the '?' character. For example, if input A is muted, and you send ' S04MUTEIA? ', the EF2211 will respond with a status message of ' S04MUTEIA1 '. 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 12 respond with a status message of ' S04AGC10 '. An example of an integer channel command is the 'GAINI' command, which adjusts the gain on the input channels. ' S04GAINIA12 ' sets the input gain of channel A to 12 dB. After sending this command, the device will respond with a status message of ' S04GAINIA12 '.
