Remote Control / Monitoring (Serial Communication)
The Inspira is equipped for serial communication through two RS232 ports. Inspira
uses a Harvard Apparatus Command Line protocol as the basis of its serial commands.
These serial commands can be found in Appendix C.
RS232 Cable Selection
To connect PC/At or laptop computers you will need a 9-pin male to 9-pin female
shielded cable; Harvard Apparatus part number 5154-353. For PCs with a 25-pin seri-
al port connection, use a 9-pin male to 25-pin female shielded cable; 5154-527.
Note: Do not use a “Null-Modem” type cable.
RS232 Cable Connection
•
Use correct cable.
•
The recommended cable length is 3 meters maximum.
•
Turn power off to Inspira and to the external device before connecting the
cable into the connectors.
•
Check that the Inspira signal ground (pin 5) is connected to the external
device signal ground.
•
Use shielded cabling to connect Inspira’s chassis ground to the chassis
ground of the external device.
Serial Communication Setup
To configure Inspira for serial communications, press [Set] key followed by the
[RS232] key. The display should read “RS232 Setup, Enter to Continue”. Press [Enter]
key to display the RS232 input/output selection menu. The display should now read
“Press 1=Input port, 2=Output port”. Select the port you would like to configure
(Input is used for serial connection to a pc; Output is used for a daisy chain setup).The
display should now show the RS232 port setup menu which reads “Press 1=Baud,
2=Bits, 3=Parity, 4=Addr”.
