TriggerBox / TriggerBox Extension

THE 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.

TriggerBox at a glance

  • TriggerBox has connectors for parallel/LPT as well as BNC inputs; the latter are all isolated from each other as well as from the other input connectors.
  • It is equipped with 8 toggle switches to regulate bit-wise which input should determine the value of the output parallel port, where the EEG amplifier is connected.
  • It can provide connection to the 16th bit of the BrainAmp trigger input, via an optical fibre cable or BNC connector.
  • It offers a stretching function for the 8th and 16th bits which is useful if the incoming TTL pulses are too short for the amplifier and would otherwise go undetected.
  • It is powered by USB
  • new as of revision 2 (released in September 2015): TriggerBox is now even more flexible and provides a virtual serial port via USB that can be directly addressed from your stimulus presentation software

TriggerBox Extension at a glance

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

In short: 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.
