3.3.4 Alternative ADU cable
Preferably choose one of the cable types listed in the table below.
Check the data sheet from the cable supplier that both the RF-
attenuation and the DC-resistance are kept within the maximum
specified values:
• ADU cable RF-attenuation at 5450 MHz: max. 25 dB including
connector.
• ADU cable modem-attenuation at 36 and 54 MHz: Max. 4 dB
• ADU cable loop DC-resistance max: 0.9 Ohm.
Also ensure that the specified minimum bending radius is
respected. If this is not the case, the loss in the cable will increase.
Check the documentation from the cable supplier.

Installation of the ACU
3.4.1 Installing the ACU
A cable relief bracket is already mounted when receiving the ACU.
The cable relief is a simple system to secure cables with cable strips.
It offers a number of holders to which you can secure the cables
from the ACU. To install the 19” rack version of the ACU, do as
follows:
1. Slide the ACU into a 1.5U space in a 19” rack.
2. Mount the screws in each side through the holes in the front and
fasten the screws to the rack. Make sure that the unit is mounted
securely according to the requirements for your 19” rack.
Use the 4 holes marked A or the 4 holes marked B.
3. Connect all cables. See
Interfaces of the SAILOR 100 Satellite TV
on page 4-1 for a description of the ACU connectors.
