Hardware and Cabling
RDTU Cable Length Switch
The distance between the DK, RDTU and CSU or RDTU to other Customer Premise Equipment
(CPE) T1 may vary (0~655 ft.) as shown. (See
transmitter must be equalized and its impedance must be matched to the cable length connecting
the RDTU to the CSU or other CPE, T1.
RDTU transmit equalization/ impedance matching is accomplished by setting RDTU SW1 for the
proper cable length (see
for SW1 location and
“SW1 Equalizer Switch and Loop Back
for SW1 setting instruction).
RDTU Loop Back Jumper Plugs
The RDTU PCB provides jumper plugs for loop back testing. Loop back tests are described in
