Probe or module malfunction

Acquisition PCB symptoms

Processor PCB symptoms

6-4
Troubleshooting: Fault analysis
Possible reason
The Dash patient monitor is

connected to a Dash Port 2 docking
station. The patient monitor's
Network Connector is inactive when
it is connected to the docking
station.
Network is disabled in boot code.

The Dash patient monitor does not

have the optional CARESCAPE
Network option enabled.
Cable or Autoport to Mport adapter

connections may be loose.
Remote control needs to be reset.

Remote control is defective.

Five or more consecutive hardware

failures have occurred.
Symptoms relative to patient signal acquisition such as missing
parameter text and waveform(s) may be associated with acquisition PCB
failure. It is important that you are able to distinguish the difference
between the general format of the display, which is generated by the
processor PCB, versus the patient signals and data that is associated
with these patient signals, a function of data acquisition, which is
generated by the acquisition PCB.
Symptoms with battery operation, network communications,
asynchronous communications, NBP control, PCMCIA communications,
analog output, audio/sound generation, and video signals as well as other
display-related problems all may be associated with processor PCB
failure. All of these are functions controlled by microcontroller or
graphics processing circuitry located on the Processor/Power
Management PCB.

Solution
Connect the network cable to the docking station's

internet connector.
Enable network in boot code.

Purchase and enable the CARESCAPE Network

option.
Restore the connection.

Disconnect and securely reconnect the remote

control from the patient monitor.
Replace the remote control with a known good one.

Review the input error log for Masimo or Nellcor

failure codes.
