Trend Data Access
7-6 Service Manual
To save specific patient data, firmly connect and properly secure the appropri-
ate cable from the data port to a host system or serial printer. Connect the data
port to a serial printer or host system by using a cable terminated with the fol-
lowing devices.
•
An AMP connector (AMP part number 747538-1)
•
A ferrule (AMP part number 1-747579-2)
•
Compatible pins (AMP part number 66570-2)
The cable should not exceed 25 feet (7.6 meters) in length using RS-232 proto-
col or 4,000 feet (1219.2 meters) in length using RS-422 protocol. The external
ITE (Information Technology Equipment) device must be certified to the latest
IEC/EN Standard 60950-1 standards. The cable used must have a braided shield
that provides 100% coverage. The shield must have a 360-degree connection to
the metal shell on the DB-15 connector and to the connector on the equipment.
No hardware flow control is used. However, support exists for XON/XOFF flow
control in ASCII mode.
100base-T RJ-45 Requirements

Caution:
Do not create sharp bends in the cable. Bend radius cannot exceed one inch.
To save specific patient data, firmly connect and properly secure the appropri-
ate cable from the data receptacle to a receiving device capable of 100base-T
communication. Connect to the data receptacle via an RJ-45 jack properly
attached to a CAT-5 or better cable. The cable should not exceed 100 meters
in length. The external ITE (Information Technology Equipment) device must be
certified to the latest IEC/EN Standard 60950-1 and IEE 802.3 standards.

Note:
The monitoring system also supports 10base-T with a CAT-3 or CAT-4 connection.

Note:
The pin layout illustrates the pins viewed from left to right on the RJ-45 jack,
beginning with pin 8. The tab snap-fits to the receptacle and requires pressure to
release it. The data lines are shielded twisted pair (STP) with an additional drain wire
to reduce crosstalk or noise.
