The trigger input is used to synchronise the Magstim 200
trigger input. Application of a 5V CMOS Logic Level to this input will
result in the instrument being triggered, provided the READY symbol
(12) is illuminated and one of the safety buttons at the base of the
stimulating coil is activated. This signal must be active for at least 10µs.
In most instances the Magstim 200
recording instrument supplied by various manufacturers. In these cases
the Magstim and the recording instrument will have to be synchronised so
that the magnetic pulse produced by the Magstim occurs exactly at the
start of the recording sweep of the recording instrument. Almost all
recording instruments have some means of accepting an external trigger
signal via either a dedicated input port or via the foot switch trigger input.
The trigger output supplies a synchronisation signal to the external
recording instrument. A 100µs 5V CMOS Logic Level pulse of either
polarity is provided at this output whenever the Magstim is discharged.

important to allow unrestricted air flow, the instrument must be placed on
a hard surface. In addition, there should be no obstructions placed closer
than 50mm to the FAN OUTLET.
