ISCAN Device

Available on macOS

Description

Interface to an ISCAN eye tracking system.

On the device, the serial I/O baud rate must be set to 115200, and a binary output format must be selected.

Signature

iodevice/iscan

Optional Parameters

serial_port

Example

/dev/tty.usbserial-FTH1RRH5

Filesystem path that represents the serial port to which the ISCAN device is connected.

If omitted, MWorks looks for a single, connected serial device. If it finds one, it assumes it to be the desired ISCAN device and attempts to connect.

start_command

128

Command byte used to start recording. On some systems, the correct value may be 132.

stop_command

Default

autostart

Default

NO

If YES, the device will start I/O automatically (as if by an implicit Start IO Device action) when the experiment starts running.

Note: Device I/O will always stop automatically when the experiment stops running, irrespective of this setting.

alt

Alternative device to use if this one fails to initialize (e.g. because the required hardware is not available). If #allowAltFailover is set to 0 or false, this parameter is ignored.
