Appendix C: Data Port Protocol

The cable used must have a braided shield providing 100%

coverage, such as a Belden cable (Belden part number 9609) or

equivalent

. The shield must have a 360-degree connection to the

metal shell on the NPB-295’s DB-15 connector and to the

connector on the PC or serial printer

. Do not create sharp bends

in the cable, as this may tear or break the shielding.

The pinouts (as illustrated in Figure 14) for the data port are listed

in Table 5.

Table 5: Data Port Pinouts

Pin Signal Name

1 RxD+ (RS-422[+] input)

2 RxD_232 (RS-232 input)

3 TxD_232 (RS-232 output)

4 TxD+ (RS-422[+] output)

5 Signal Ground (isolated from Earth Ground)

6 AN_SPO2 (analog saturation output)

7 NC_NO (relay closure nurse call, normally open)

8 NC_NC (relay closure nurse call, normally closed)

9 RxD- (RS-422 [-] input)

10 Signal Ground (isolated from Earth Ground)

11 Nurse Call (232-level output)

12 TxD- (RS-422 [-] output)

13 AN-PULSE (analog pulse rate output)

14 AN-PLETH (analog pleth wave output)

15 NC-COM (relay closure nurse call common lead)

GND is ground, TxD represents the Transmit Data line, and RxD

is the Receive Data line.

The pin layouts (as viewed from the rear panel of the NPB-295)

are illustrated in Figure 14

. The conductive shell is connected to

earth ground when connected to a PC or printer.
