Console Connection ( optional – not usually needed for initial setup ). The Console Cable is needed at initial
setup only if your system cannot use the voip’s default IP address. In that case, the Console Cable is
needed to change the MultiVOIP’s IP address. Also, if, at a later date, you need to update the
MultiVOIP’s firmware, you will need to connect the Console Cable because it is required for that process,
as well.
If needed, connect the Console Cable (RJ45 male to DB9 female) between the MultiVOIP and the control
PC. Plug the RJ-45 end of the cable into the CONSOLE port of the MultiVOIP and the DB-9 end into a
serial port on the PC.
