No i have no CD-ROM...do you have the CD-ROM they talk about in the manual?
patient datalogger is only enabled in the paided version and i can't enable the datalogger...What´s your current PatientDataLogger setup?
yes.. Enabled the handshaking,when the monitor connected with the DSUB 9 pin connector with the pc via Terminal..Did you enable or disable hardware handshaking on the PC side?
we have connected the Bedside monitor to oscilloscope with RS 232 DB-9 connector...Are you sure you use the correct RS-232 cable with correct pin setup? If you are not sure about that you have to use your scope and measure all the RS-232 connector wrt RS-232_GND.
Isn´t it negative? = -8VNo data voltage.. continuous 8V out (not the data)

pin 3-TX
pin 5-GND
this is the connection

Hi,
Isn´t it negative? = -8V
Btw: do you measure the signals from the PC on the RS232 connector? And during this measurement you (tried to) transmit date from PC to the device?
Maybe the hardwae handshake singal disabled data transfer. --> do a test without hardware handshake.

Your hookup appears to be 2 wires. This resembles a null modem (as mentioned in post #2). It does not need handshaking. Therefore try shutting off handshaking and then you might see a signal on the oscilloscope.
It might be necessary to restart the sending unit, or maybe it is sufficient to stop the communication and resume.
