SPECTRALIS 2
7.2 Safe file operation
I. If you are working with an Apple Macintosh do not forget to unmount the
drives after you’re done copying data to flash rom, ramdisc or a smart media
card. This is easily accomplished by dragging the drive icon onto the trashcan.
If you don’t do it data will not be written completely. In a worst case scenario
incomplete data or interrupted data transfer can lead to data-loss on your media!!
7.3 USB Troubleshooting
In case, you connected the USB cable to your computer and the computer is
not mounting the Spectralis drives, you should first make sure to connect the
spectralis directly to your computer. The Spectralis is a highspeed USB device.
A couple of USB HUB's can't handle these devices.
Older computers are maybe only running USB1.1 and are not configuring USB2
devices correctly, that are trying to connect via Highspeed. In the USB
specification is exactly described, how a host should handle that. A 100%
compliant host will set the client into USB1.1 mode automaticly, if the host is
not USB2 compatible.
However - some older computers with outdated bios versions are maybe not
handling that this way and are only reporting an error message or nothing. In
this case you can set the Spectralis to USB1.1 Fullspeed mode manually in the
system menu.
Press and hold the [Shift]-button and push the [System]-button to enter the
system-menu. The following display dialog will appear:
1/5:System SN:00xxxxxx V1.5x
Drum:OFF Contr:100 Save:Yes Load:ASK
Press [Page-Up] to reach the second menu page:
2/5:System SN:00xxxxxx V1.5x
USB:FULL DSnd:YES Sync:DIS Play:YES
The first rotary encoder allows to change the USB communication speed:
USB: FULL - Fullspeed Mode, USB 1.1 compatible
USB: HIGH - Highspeed Mode, USB2 compatible
USB: OFF - USB turned Off - the lowest available speed;-)
When ”Mounting“ a
Drive it becomes
accessible
for the operating
system
Once the operating
system
senses a new drive it
will try to access it.
This process is
called ”moun-ting”.
During this process
the drive is as-
signed to an
identifying letter
