EPU160 Event Recorder mmb16
- USB connectivity
- virtual serial port technology
- binary events converted to human readable plain text
The eDAQ mmb16 unit is an Event Recorder with a USB/virtual serial port connection.
Each mmb16 records the status of up to 16 time-stamped event lines (TTL or contact closure events). Multiple mmb16 units can be connected to the same computer. Each event can be used to trigger the output of a pre-set, user-defined, text message as a serial formatted character string over the USB interface. That is, an event takes place and the mmb6 sends out a human-readable plain text message to your computer.
The events are typically on/off, high/low, or other binary type-signals found in process control, animal behaviour, or similar experiments. For example pressing of a button to dispense a food reward is an on/off event. Other situations could be:
- lights, on/off
- heater, on/off
- flow pump, high/low
- position (eg a rat passing a point in a maze), yes/no
The mmb16 is supplied with a Chart software extension which allows easy use with an e-corder and converts the binary events to messages which appear as 'Chart comments'. Alternatively the serial protocol can be accessed by:
- writing your own software, for example in LabView, C#, Visual Basic, etc.
- terminal emulation software compatible with serial (COM) ports, eg TeraTerm, HyperTerminal.
- other serial (COM) port compatible software that can log responses into a file or Excel document, eg WinWedge, HyperAccess.
