along the left side of the screen has been eliminated, re-adjust the sharpness control for
the best image. This completes the tuning procedure for the C/Port.
Re-adjusting the C/Port
If, during the adjustment procedure, you become lost or confused, it is best to just
start over again. Begin by resetting the color switches to the Off positions. Do this by
adjusting each switch, one at a time, until it turns the picture off and then advance the
switch by one position, to Position 1. When you complete this, each switch will be
returned to the start position as shipped (see Figure 36). Finally, turn the sharpness
control fully counter-clockwise. From this point you can go back to the beginning and
start the tuning procedure over again. Moving the C/Port to a new location may
require re-adjustment of the C/Port unit.
Locking out Mass-Storage Devices
When using ClearCube’s C/Ports, you have an additional feature that provides
increased levels of security. The R Series PC Blades offer a unique Mass Storage
Lockout (MSL) security feature that disables the use of any USB mass storage device
at the desktop (e.g., key drives, floppy drives, CD-ROM drives, etc.). The default
factory setting does not enable this security feature – thus in the default mode, any
USB device, including mass storage devices connected to the C/Port, will be
recognized by the operating system. However, Switch Manager allows setting MSL in
software to lock out the use of storage devices.
• To enable MSL in hardware, a jumper on the PC Blade needs to be moved from
the default position to the adjacent position. You will need a set of needle-nose
pliers to access the MSL jumper.
• See Figure 37 and Figure 38 for the jumper locations by Blade model number.
The default position for the jumper connects pins 2 and 3 (USB mass storage
devices will function normally).
• When the jumper is in the default position, you can also use a software setting to
disable mass storage devices. This software setting is accessible through the
Switch Manager software.
NOTE: When the MSL jumper is physically set to lock out mass storage devices, the
software cannot override this.
