Name: Visual Stim Synchronization Interface
SKU: STMSYNC-VIS
Availability: InStock

Description

The Visual Stim Synchronization Interface is used to generate TTL level event markers for visual stimulus presentation systems. Four light sensitive sensors (photodiodes) are easily attached to the corners of a presentation monitor or split to attach to multiple monitors. By alternating the corners of the monitor between black and white squares underneath the sensor locations, different TTL level signals may be generated to identify both the specific visual stimulus that is on the screen as well as mark the onset and end of presentation. A black or dark area will be a 0 V level while a white or bright area will be a 5 V level. More than four stimulus types may be recorded by using binary coding with multiple sensors activated at the same time.

The Visual Stimulus Interface has a female DB25 connector to interface with the 25-pin port of a BN-SMART-IOCBL for use with a BioNomadix Smart Center or of an STP100C* for use with an MP200, MP160 or MP150 Research System.

BN-SMART-IOCBL + Smart Center is compatible directly out of the box
STP100C must provide external power and may be connected to an MP200 or MP200; extension cable CBL110C can be added if increased distance is required.

* Older STP100C may need to be updated to enable external power to run the photodiodes; if necessary, contact BIOPAC Support for an RMA.
