design of the wire. Because CAT5 consists of twisted pairs that are twisted together
in the cable, unequal wire lengths are created.
NOTE: Only the QM IN 1 port features delay compensation for signal skew. For
information on maximum cable lengths, refer to "QM (QM versions only)" on page
17.
The maximum aggregate cable length from QM transmitter to QM receiver is limited
by the loss of bandwidth over long distances and the amount of available skew
compensation. A cable rated at 15 ns of skew per 100 meters (328 ft.) means that a
cable will have no more than a 15 ns difference between the fastest and slowest RGB
signals over 100 meters of cable.
To determine the allowable maximum length of installed cable, the installer must
first perform a calculation based on the skew rating of the cable. The use of low-
resolution signals may allow increased cable length but must be tested with the
sources to be used. In any case, the maximum aggregate cable length should be
limited to 328 feet to prevent loss of bandwidth.
Skew compensation is primarily relevant to RGB sources; however, any/all video or
VGA signals may experience a loss of quality over very long lengths of cable. This
phenomenon is due to the added resistance and capacitance of longer cable lengths,
and is not particular to either Crestron and/or QuickMedia systems. To ensure
sufficient bandwidth to support signal resolutions up to 1600 x 1200, the maximum
aggregate cable length should not exceed 328 feet. The use of lower-resolution
signals may allow increased cable length but must be tested by the installer with the
sources to be used.
For pin assignment information, refer to "QM (QM versions only)" on page 17.
Refer to page 23 for additional QuickMedia network wiring information.

Identity Code

All equipment and user interfaces within the network require a unique identity code
(Net ID). These codes are two-digit hexadecimal numbers ranging from 03 to FE.
Refer to "Cresnet" on page 29 for instructions on setting the unit's Net ID. The Net
ID of each unit must match an ID code specified in the SIMPL Windows program.
Refer to the latest version of the Crestron Isys i/O™ TPMC-15 & TPMC-17 Series
Programming Guide (Doc. 6350) for details of the SIMPL Windows procedure.

Configuring the Touchpanel

NOTE: The only connection required to configure the touchpanel is power. Refer to
"Hardware Hookup" on page 48 for details.
The TPMC-15 and TPMC-17 are configured from the SETUP MENU.
NOTE: If no project has been loaded, or if an invalid project has been loaded, the
touchpanel displays an error message and defaults to the SETUP MENU screen.
