Casio PX-150 Simple Manual

A single session is concluded only when this Instrument returns an IPS (Individual Parameter Send)
in response to an IPR (Individual Parameter Request) from an external device, or when an external
device or this Instrument spontaneously sends an IPS. If this Instrument received an IPS, the value of
the applicable parameter is changed.
Depending on the function of a parameter, Individual Parameter Send may be used to issue a com-
mand to the Instrument or Individual Parameter Request may be used to check Instrument status
information.
