Need to sync your neural data with external triggers? Use an I/O board to connect up to 8 digital inputs to the acquisition board. Since its internal components are completely passive, the I/O board can be also be used to relay digital outputs, analog inputs, and analog outputs.

If you're interested in building your own I/O Board, follow the instructions here.This page has been moved to: https://open-ephys.github.io/acq-board-docs/User-Manual/Peripheral-devices.html#ioboard
If you just need one or two channels in a hurry, you can make a quick adapter cable with pretty little effort.

The easiest test is to check continuity and absence of shorts with a multimeter, using two I/O breakout boards and a hdmi cable. Alternatively, the same test can be performed with a acquisition board by plugging the hdmi cable into the Ain port and testing ontinuity between the bnc connectors and the row of 3-pin jumpers on the aq. board.
