IrDA, RS232 and Nursecall Specification
IrDA / RS232 / Nursecall Feature
The IrDA (or RS232 / Nursecall optional feature) is a feature that allows the Pump to be connected to an external device for the purpose
of data communication .
w
The nursecall interface provides a remote backup to the internal audible alarm . It should not be relied upon to
replace monitoring of the internal alarm . The signal leaves the IrDA port and the RS232 for Nurse call within one
second after the alarm condition is detected .
Refer to the Technical Service Manual for further information regarding the RS232 interface .
The assessment for the suitability of any software used in the clinical environment to control receive data from the
Pump lies with the user of the equipment . This software should include detection of the disconnection or other
failure of the RS232 cable .
Any connected analogue and digital components are required to meet IEC/EN60950 for data processing and IEC/
EN60601 for medical devices . Anyone connecting additional devices to the signal input or output is a system
configurator and responsible for meeting the requirements of the system standard IEC/EN60601-1-1 .
To connect to the RS232 port use spare part 1000SP01183 - RS232 cable .
