Figure 14: Data Port Pin Layout

Pins 2, 3, and 5 provide data in RS-232 format.

Pins 1, 4, 9, and 12 provide data in RS-422 format

. TxD+ and

TxD- are the differential transmit data pair

. RxD+ and RxD- are

the differential receive pair.

No hardware flow control is used

. However, in the ASCII mode

XON/XOFF flow control is supported.

BAUD RATE

The baud rate can be changed by pressing the SETUP softkey, the

NEXT softkey, and then the COMM softkey

. Use the Adjust

Up/Down Buttons to select a baud rate of 2400, 9600, or 19200,

depending on the capabilities of the attached equipment.

REAL-TIME DISPLAY FORMAT

While on AC power and while the NPB-295 data port protocol

setting is set to ASCII (refer to Start-Up and Use section),

real-time data is continuously sent to the data port on the back of

the NPB-295

. Patient data can be obtained through the data port

by connecting it to an attached PC or serial printer

. When a

real-time printout or display is being transmitted to a printer or

PC, a new line of data is displayed every 2 seconds

. Column

headings will be displayed or printed after every 25 lines, or if

one of the values in the column heading changes.

Data cannot be obtained if the NPB-295 is operating on battery

power.

Note: If the data output stops transmitting, turn the power off

and back on again or, if connected to a PC, send an XON

(Ctrl-q) to reset the monitor.

An example of a real-time printout is shown in Figure 15.
