The Physical Inputs and Output Connections
Connect input devices and output devices to the router according to the requirements of your
system and according to the connector types for the particular router(s) you have. Keep in mind
that there are 16 normal video inputs, 2 bypass video inputs, 2 CQX outputs, and 6 auxiliary
(normal) video outputs. All inputs and outputs use BNCs.
 Video cable length limits are standard: 400m for SD, 150m for HD, and 100m for 3Gig (80 m
for 3Gig CQX routers), for Belden 1694A (or equivalent) cable. Input equalization is automat-
ically adjusted according to that cable type and cable length.
External Video Reference
The CR1602-SD-CQX accepts composite (NTSC or PAL) reference. The other two CQX routers
accept either composite or tri-level video reference. All switch according to SMPTE RP168-2002.
Connect your video reference input to either video reference connector on the rear of the
router. Terminate the reference signal (or chain of reference signals) using a 75W terminator on
the other reference connector.
Button Legends
The buttons are pre-labeled at the factory, but you can create labels of your own. Use a desktop
publishing program to create your own button legends. The legends should be transparent and
no larger than 0.40”× 0.40” (10mm square). A 3/8” (9.5mm) square insert will allow a little clear-
ance. The clear plastic material used for overhead transparencies is suitable for printing legends.
To apply a label to a button, pull the clear plastic cap from the button, insert the label in the cap,
and replace the cap. The caps come off easily. No tools are required. We recommend that you
not use adhesive.
 Button legend templates (in Word, ® Illustrator, ® and Freehand ® formats) are available on the
Compact Router documentation and software disk you received with your CR Series
product(s). Simply type (or draw) the legends you want and print the page on transparent
film. Then cut apart the button legends and insert them under the clear plastic button caps.
