tesira ex-logic

Tesira EX-LOGIC is a half-rack logic box for use with Tesira SERVER, SERVER-IO, and TesiraFORTÉ AVB and non-AVB devices. The EX-LOGIC provides both logic inputs and outputs, can be configured as a control interface and through software. There are 16 total connections that can be used as inputs or outputs. 12 of the connections are designed as Logic connections only, and will accept contact closure or 5V TTL for input or provide a maximum of 40V/300mA for output. The remaining 4 connections can also be used for Logic connection or as variable voltage control input (e.g. interface to a potentiometer). The EX-LOGIC also provides a serial port for the output of command strings that can be used to send action commands to other equipment in the system. The EX-LOGIC communicates with the Tesira control network for audio networking, configuration, and control, and is powered by PoE.

Case Studies
  • Firmware

    • Tesira Firmware v3.0.0.60
      **Please note that there is a known issue in the public release version 3.0.0 of Tesira Firmware.**

      The issue can cause Tesira expanders to occasionally become undiscoverable on the network, which causes a loss of audio to/from those expanders. This issue only affects Tesira systems that include Expanders and are set up in “separate” network mode, meaning that the Control network is completely isolated from the AVB network. It will not affect systems that are in “converged” network mode, which is the default (and more common) configuration.

      If your system meets this criteria or if you have questions regarding this issue, please contact the Biamp Technical Support Team at 1-877-BIAMP-XO for more information.
