1.28 Trend Storage
1.28.1 Installation and Use of the Extended Trend Feature
The Spectrum
®
/Spectrum OR
™
monitor is capable of storing, in non-volatile memory, up
to 120 trend values for each parameter, and for Spectrum
®
only, up to 6 minutes of OXY-
CRG data. With the addition of the Extended Trend card (P/N 0996-00-0052-01), the
Spectrum
®
/Spectrum OR
™
is capable of storing up to 500 trend values for each
parameter, and for Spectrum
®
only, up to 12 hours of OXY-CRG data.
This feature is added to the Spectrum
®
/Spectrum OR
™
by inserting the Extended Trend
card (P/N 0996-00-0052-01) into slot PCM1 on the right side of the monitor. The card
should be inserted before monitor power-up, and never removed during monitor operation.
In order to guard against accidental removal, the card slot is designed so that a tool is
required to eject the card after insertion.
The Extended Trend feature is automatically enabled when the unit is powered-up following
card insertion.
NOTE: All prior trended information is lost upon installation of the
Extended Trend feature.
1.29 Software Download
1.29.1 Download Operation
A download flashcard must be installed in PCMCIA slot PCM2 prior to power up. When the
unit is powered on, the valid download card will be read and downloaded to the Host CPU
module only. While the images are being downloaded a beep will sound approximately
once every second until the download is complete. Once complete, the unit will then run
automatically, first displaying the Spectrum
®
/Spectrum OR
™
logo then proceeding to
normal runtime mode. A display box will be displayed if it is determined that the images
downloaded to the Host CPU module do not match the images in the attached CP and/or
Front-end modules and/or EPM modules. This display box, shown below, will indicate the
Host CPU software version, the current version on the CP, Front-end and/or EPM modules
and the software version being downloaded to the modules. The images will automatically
load and the status message Complete will appear, after the download is complete.
NOTE: To ensure that the EPM module download is complete,
reboot the unit.
