6.4.4 Installing Cat-5 Extender
The Cat-5 Extender (PN #UNS-EX170-1) increases the maximum length of the
Cat-5/6 ScTP cable run that connects the Accel Hub to the RAU from 100 meters to
170 meters. The minimum cable length between the Hub and Extender is 90 meters
and the minimum length between the Extender and RAU is 20 meters. Beyond the
minimum lengths, an additional 60 meters of cable, maximum of 170 meters total,
can be inserted before or after the Extender.
Considerations:
• Ensure that the following minimum and maximum cable lenghs are met:

1. Attach the Cat-5 Extender securely to a stationary object (i.e., wall, pole, ceiling
tile).
2. Attach the Cat-5/6 cable that is coming from
the Accel Hub to the
TO UNISON SYSTEM con-
nector on the Extender.
If the green LED lights on the Extender, then you
have correctly connected the Cat 5/6 cable that is
connected to the Accel Hub.
If the LED does not light, then you may not have connected the cable at the Accel Hub. If
the cable is connected and the LED still does not light, then the Unison system may not be
powered on, the Cat-5 cable may be cut/broken, or there is a problem with the Extender.
Verify that the
Accel Hub is connected to AC power and the power switch is in the ON
position.
3. Attach the Cat-5/6 cable that is coming from the RAU to the TO UNISON RAU
connector on the Extender.
CAUTION: Do not insert the RAU cable into the Extender until the green LED
on the Extender lights. Otherwise, you may damage the RAU.
