Appendix C: Rs-232 Serial Data; Connector; Data Stream - GE Giraffe Service Manual

Warning:
The computer or RS-232 monitor's user program must continuously check the data link. The
program should constantly verify connection to the incubator controller and check for updated
data.
nOTE: In the event of a power failure, all serial communication will cease until power is restored.
C.1 rS-232 Connector
The Nurse Call and the serial data output share the same female, nine pin, d-type connector.
• Pin 2: Receive Data (incubator input)
• Pin 3: Transmit Data (incubator output)
• Pin 5: Gnd (Signal Ground)
Cable requirements
The user interface cable must have capacitance less than 1500 pF. It should be a shielded cable such as Belden
9611 with AMP shielding kit 748046-1 and ferrule 747579-8.
C.2 Data Stream
The data stream from the Giraffe products is repeated every two seconds. The RS-232 parameters are
19200bps baud rate, no parity, 8 data bits, and one stop bit. The data is in ASCII format; the string is described
below.
