Sending data to a remote computer

When connected to an external modem, the 3900/3900P supports the transmission
of up to 24 hours of trend data over public telephone lines to a modem-equipped
remote computer. The telephone connection may be initiated by the remote
computer or by the 3900/3900P.

Remote computer requirements

Your remote computer must be equipped with a serial communications software
program (e.g., ProComm Plus by Data Storm Technologies) or a terminal
emulation program, such as those that are incorporated within some operating
systems (e.g., the Microsoft Windows Terminal program in Windows 3.1 or the
Microsoft Hyper Terminal program in Windows 95 and Windows NT).
Data are transmitted to a remote computer using the Xmodem or Xmodem/CRC
protocol. The communications program should support one of these protocols.

Preparing for transmission

The user of the remote computer may need to set up the remote computer
modem as described in the instructions for the modem. Before trend data can be
transferred, the remote computer user must set up the communications program
and verify that it is configured as follows:
•
•
Important: The communications program and the oximeter must use the same
baud rate. To set the 3900/3900P baud rate, see SETTINGS in chapter 2.

Dialing and answering calls at the remote computer

Consult the instructions for the communications program used on the remote
computer for details regarding dialing and answering features.

Receiving the data file at the remote computer

The remote computer user must select the Xmodem or Xmodem/CRC binary
transfer protocol to receive a data file from the 3900/3900P. It is recommended
that the received data be saved to a file on the remote computer. Saving data to a
file is supported by most communications programs and is activated by the
computer user. Although a successfully transferred data file can be viewed and
edited as an ASCII file, if the computer user must choose either ASCII or binary,
the user should select binary.
5-8
No parity, 8 data bits, 1 start bit, 1 stop bit, full duplex, and hardware flow
control.
Baud rate of 9600, 19.2K, 38.4K, or 57.6K BPS.
To initiate a call from the remote computer, the remote computer user will
need to set up the dialing features of the communications program.
To receive a call from the 3900/3900P, the remote computer user may need to
complete the connection by answering the call. Some communications
programs may require the user to type the modem command for answering
an incoming call: ATA <return>
