TriggerBox /TriggerBox Test I/O
  • Handles and merges triggers from different sources by means of parallel/LPT and BNC inputs

  • Equipped with 8 toggle switches to flexibly regulate bit-wise input to output routing

  • Connects to the 16th bit of the BrainAmp trigger input via a fiber optic or BNC connector

  • Provides a reliable virtual serial port via USB that can be directly addressed from your stimulus presentation software

TriggerBox: A must-have tool to easily handle and merge triggers from various sources

The TriggerBox helps to handle and merge triggers arriving from different sources, which is quite often a requirement in complex laboratory setups. For example, some markers might arrive from experiment control software via parallel - DB25 (LPT port) - input while other devices - like MOVE, TMS, etc. - may communicate through BNC. If so, the amplifier should record all the triggers simultaneously.

The TriggerBox Extension offers 8 additional BNC connectors which can be linked to the 8 upper bits (from lines 8 and 15) of any BrainAmp amplifier or used as a standalone solution for amplifiers such as actiCHamp Plus in situations where stretching, switching and isolation functions are not required. It can also be connected to the output trigger port of the actiCHamp Plus in order to lead the outgoing signal to the BNC ports.

TriggerBox and TriggerBox Extension serve as a general adapter which replaces many small adapters, cables and boxes and thus are for sure a useful addition to any lab.

Using the TriggerBox as virtual serial port

To use the TriggerBox as virtual serial port you need to install a small application, the TriggerBox Test IO.  More detailed information is available in our newsletter article “Millisecond precise trigger without a parallel port”.
