Trend Data Access
7-2
Service Manual
Note:
Trend memory always contains the most recent 48 hours of data, with newly collected
data overwriting the oldest data on a rolling basis. The monitoring system continues
to record data points as long as it is powered on, with “blank” data points collected
if no recommended sensor is connected to the monitoring system or patient. “Blank”
data overwrites older patient data if the memory is full. To save old patient data, turn
the monitoring system off when not monitoring a patient and download the trend
memory before it fills up and overwrites the old data with new data (or “blank” data).

Data Port Connectivity
7.3.1
Overview
The monitoring system contains three different data ports and two antennae.
Each data port has a different intended use.
1.
Serial DB-15 data port —
This female DB-15 port provides RS-232, RS-422, and
differential transmission data connectivity. Use for sending historical trend data to
a serial printer for an ASCII print-out.
2.
RJ-45 port —
This female 100-base-T, wired, ethernet-capable port provides
connectivity for digital data output.
3.
Serial USB port —
This female USB port allows for faster data transfers. Use this port
for updating firmware or for digital data output storage.
4.
Radio-frequency (RF) antennae —
Two radio-frequency antennae broadcast data
to a wireless LAN network, should the proper configuration exist.
