Glidepad, Mouse, Trackball, or Other Input Device
It is usually possible to use a Microsoft
®
-compatible serial mouse, trackball, glidepad or other
external input device with your HFA II-
i
. These devices may be used as an alternative to pressing the
touch screen. They may be used in conjunction with the optional external keyboard. The keyboard is
not necessary to utilize these devices. For simplicity in describing the feature, the term “glidepad”
will be used to represent any compatible input device. The serial mouse or trackball is connected to
the green PS/2 connector on the PS/2 splitter adapter that is plugged into the HFA. The HFA II-
i
must
be turned off when attaching or removing any input device. See Chapter (2), "General Operation,"
for further information regarding use of the
external input devices.
External VGA Monitor
Your HFA II-
i
allows you to connect an external VGA monitor. This can be very useful for training
purposes, where you wish to allow easier viewing for large groups of people. Commands issued
with the keyboard and glidepad can be seen on the external screen. Touch screen capability is not
available on the external monitor. The HFA II-
i
touch screen remains available for use when using
the external monitor. Output to the external monitor will display in black & white, even when using
a color monitor. Connection of the VGA monitor is made to the VGA video port found on the back of
the HFA II-
i
. Refer to Figure 1.8 and Figure 1.9.
Surge Protectors
Carl Zeiss Meditec recommends the use of
surge protectors or UPS (Uninterruptible Power Supply)
systems to help isolate the HFA II-
i
from power surges or fluctuations. The HFA II-
i
is very sensitive
to line voltage changes and may experience database problems if subjected to brownouts, power
outages or surges of voltage. Hospitals, surgery centers, and offices with instruments which
consume large amounts of power, such as surgical lasers, especially should be careful to plug the
HFA II-
i
directly
into a UPS or adequate surge protector. Plugging the power table into the UPS may
not be adequate protection. For the HFA II-
i
, exclusive of the Power Table, Carl Zeiss Meditec
recommends a surge protection system with a rating of 450 volt amps or greater.
