==Description==
 
−
The Digital Event Recorder is a device for recording timing pulses used for synchronizing several devices and is developed by the [[Technical Support Group]]. The device is based on a Raspberry Pi. The software on the raspberry pi is developed by Günter Windau.
 
−
 
 
−
The device has isolated inputs that can register trigger pulses from other devices. The incoming pulses are timestamped and can be used afterwards for synchronization of data collected from different devices. The device has an Ethernet connection and can be instructed and read out by your MATLAB program. The MATLAB software for the device is available in the biofysica repository on [[Gitlab]].
 
−
 
 
−
The synchronization is based on Lab Streaming Layer (LSL). This protocol has a built-in timing facility which is designed to achieve sub-millisecond synchronization on a local network.
 
−
The 8 channel digital event recorder is a 1U 19" rack version of the device.
