The power supply section of the unit is built to sustain the specified line fluctuations
and still allow the system to function within its operating margin. As long as the
incoming voltage is adequate, the power supply provides all the logic voltages
necessary to support the monitor unit.
Unusual AC line variations may cause undesirable system shutdowns. As a first step
to reduce line variations, correct any possible feed problems in the distribution
system. If this correction does not solve the problem, use a constant voltage
transformer. The constant voltage transformer stabilizes the input voltage to the
systems by compensating for voltage changes at the primary in order to maintain a
steady voltage at the secondary. When using a constant voltage transformer, check
that the power rating is sufficient to supply the unit.

Listed below are general compatibility issues that apply to the 5012KPM(T) and
5015KPM(T):
••••
The KPM(T) monitor must be powered up before the host computer is
powered up so that the host can determine if a keyboard and mouse are
connected. If the KPM(T) monitor is not powered up first, the host will
determine that there is no mouse or keyboard available.
••••
Once the complete system is up and running, the KPM(T) monitor can be
power cycled at any time without affecting the host. It is the initial power up
of the host that requires the power up sequence.
••••
If an operating system is loaded on the host computer, the KPM(T) monitor
should not be used as the host mouse or keyboard during the loading of the
operating system. Instead, a mouse and keyboard can plug directly into the
host for the loading of an operating system. The KPM(T) monitor can be
used for the monitor only during the loading of the operating system.
••••
The IBM specification for PS/2 ports defines both a Type I and Type II
interface. The KPM(T) monitor is a Type II interface.
Pro-face
has determined
that not all PS/2 compatible devices are Type II compatible. The user can try
any standard PS/2 device, but
Pro-face
only guarantees the approved list.
••••
Non-standard devices should not be used with the KPM(T) monitor. If a
device does not meet the standard PS/2 definition, and does not use the
standard PS/2 driver that comes with the operating system, it will not work
reliably with the KPM(T) monitor. For example, if a device requires its own
separate driver it probably will not work because it was written to expect that
the device would be plugged directly into the computer’s host port. In the
case of the KPM(T) monitor, this is not true.
