Redback® A 4480B
8 In to 8 Out Audio Switcher
The consoles are connected to the A 4480B via standard Cat5e cabling as shown in Fig 5.1B. The maximum distance
between the A 4480B and a paging console is 300m. Note that each paging console must be assigned an ID number
before operation (see section 5.1.2 DIP switch settings).
A maximum of eight consoles can be connected at one time but only used in certain configurations. There are four RJ45
ports on the back of the A 4480B which can be used to connect the A 4481 paging consoles. Each port can accomodate a
maximum of two paging consoles. Fig 5.1B shows how to connect one paging console per RJ45 port.
5.1.4 Cascading the paging consoles
If more than four paging consoles are required the consoles can be cascaded together with the addition of external power
supplies. Fig 5.1C shows how to connect eight paging consoles at once. In this fig consoles 1-2 are connected to Port 1,
consoles 3-4 to port 2, consoles 5-6 to port 3 and consoles 7-8 are connected to Port 4. Please note: A maximum of 2
paging consoles can be connected per RJ45 port on the A 4480B. Each additional paging console has a dedicated power
supply and the total cat5 cable run can be no longer than 300m. I.e the maximum length of cable (after all paging
consoles have been cascaded) to the furthest paging console is 300 metres.
