NetStation - aleslab/Psychtoolbox-3-aleslab-fork GitHub Wiki

       Establishes TCP/IP connection to the [NetStation](NetStation) host computer.  
       "host" is the hostname as a string (e.g., 'anything.com' or '187.14.176.12')  
       "port" is the ethernet port to be used. Default is 55513.  

       Disconnects from [NetStation](NetStation) host.  

       Synchronize to the connected host. "[SynchLimit](SynchLimit)" could specify the maximum allowed difference  
       IN MILLISECONDS. Default is 2.5 ms.  

       Synchronize to the amps built-in NTP server using EGI N-type  
       synchronization (eci\_NTPClockSynch method). So far only tested  
       for 400 series amps with [NetStation](NetStation) 5.3 and Psychtoolbox on  
       Linux! ntpserver is the amp ip, e.g. '10.10.10.51'.  

       NTP synchronization might possibly also work for 300 series  
       amps (using the [NetStation](NetStation) PC as NTP server) and other  
       [NetStation](NetStation) versions and OS. Please report on the Psychtoolbox  
       mailing list if you could test other versions (EGI photodiode  
       and AV tester box required).  

       Note that Psychtoolbox client time is NOT required to be  
       adjusted to NTP server time. Rather current NTP server (i.e.  
       amp) time is queried at event time (using the [GetNTP](GetNTP) client).  
       Possible delays between event and NTP request times and network  
       delays are accounted for. NTP synchronization is expected to be  
       considerably more accurate than regular synchronization on  
       quiet local networks.  

       Instructs [NetStation](NetStation) to start recording.  

       Instructs [NetStation](NetStation) to stop recording.  

       Send an event to the [NetStation](NetStation) host. The 'EventNoAck' variant doesn't  
       wait for acknowledgement of reception of the event, whereas the 'Event'  
       version does. Note that the 'EventNoAck' command is included for  
       completeness. It is not a good practice to skip waiting for  
       acknowledgements. If time is an important factor, Event commands can be sent  
       at a later opportunity within a session (e.g., in blocks at the end  
       of experiments).  

       "code"      The 4-char event code (e.g., 'STIM')  
                   Default: 'EVEN'  
       "starttime" The time IN SECONDS when the event started. The VBL time  
                   returned by [Screen](Screen)('[Flip](Flip)') can be passed here as a parameter.  
                   Default: current time.  
       "duration"  The duration of the event IN SECONDS.  
                   Default: 0.001.  
       "keycode"   The 4-char code of a key (e.g., 'tria').  
       "keyvalue"  The value of the key (any number or string)  
                   The keycode-keyvalue pairs can be repeated arbitrary times.  

        Flushes the read buffer.
