I connected a powered-on
P2ZCIM to another chain
and now the chain size is
wrong. What happened?

The P2ZCIM you added was a Master P2ZCIM. When it was added to
the new chain, it became the Master of that chain as well. The added
P2ZCIM reset the chain to use its last known chain size. The user
should momentarily power off a P2ZCIM before adding it to a new chain
to prevent this problem. The user can resize the chain to correct this
issue.

Enhanced User Station

What are the differences
between the Standard User
Station (P2-UST) and the
Enhanced User Station (P2-
EUST)?

The P2-EUST supports video quality at longer distances and higher
resolutions than the P2-UST. When used with automatic P2CIM-Axxx
CIMs, the P2-EUST will support automatic skew compensation, based
on cable distance and cable types. If desired, automatic skew
compensation can be manually overridden. The improved video quality
permits the range of video gain settings to go from -15 to +15 for the P2-
UST to 0 to +6 for the P2-EUST.

What is skew compensation
and why is it necessary?

Red, green and blue signals have different skews (time delays) when
traveling the distance from the target server to the monitor connected to
a User Station, due to differences in cable distance and type. Skew
compensation resynchronizes the red, green and blue signals by adding
a time delay on the signal that arrives at the user station earlier than the
others.

When I use the P2-EUST,
how can I adjust the video
quality to change the skew
compensation and gain
settings?

Skew compensation is automatic on the P2-EUST, using the automatic
P2CIM-Axxx CIMs. This automatically adjusts for signal losses based on
cable distance and type. Manual skew compensation can, however,
override the P2-EUST’s automatic adjustment, and will continue to be
provided with older CIMs.

To manually set skew compensation, connect to the channel you wish to
adjust. Press the Hot Key to activate the Selection Menu and click on the
[*] or [/] keys on your numeric keypad to select Red, Green or Blue skew
delay. Then click on the [ + ] or [ - ] keys on your numeric keypad. The
Skew compensation range is 0 to 31.

To set video gain, see the adjustment value appearing in the Message
Banner at the bottom of the screen; click the [ + ] and/or [ - ] keys to
adjust video gain from 0 to +6 or (from -15 to +15 for the P2-UST) until
you are satisfied with the video quality.

What video resolution and
distances can the P2-EUST
support?

Video quality is often subjective and depends on the cable and monitor
being used, the cable distances and the resolution that a user has set.
The P2-EUST provides video resolutions greater than 1920 x 1440 at
distances over 1000 feet at refresh rates of 60 Hz, and 1600 x 1200 at
distances up to 1000 feet, at refresh rates of 75 Hz and 85 Hz.
