Configuring the IP connection without CXproᴴᴰ
If your network does not have a DHCP server, then the FBVi controller will use a Recovery IP address,
which is made up as follows:
• The first byte of the IP address is set to 10
• The 6 digits of the numerical part of the serial number grouped into 3 sets of 2 digits to form the last
3 bytes of the IP address.
For example, a FBVi with serial number
039188D
will be allocated the Recovery IP address of
10.03.91.88
Note: For a laptop (or PC) to communicate with a FBVi configured in this way, the IP address of the
laptop’s Ethernet port must be set to a subnet that is compatible with the FBVi’s IP address.
For example, if the FBVi has an IP address of
10.90.10.01
, the laptop could have an address
something like
10.90.10.nn
with a subnet mask of
255.255.255.0
.
Note: If the default IP address is used on a network, it can cause an IP Address conflict if the network’s
subnet mask is
10.0.0.0/8
(see
Subnetwork (Subnet)
on page 9).
It may be possible to reach the FBVi over the network but BACnet messaging may fail.
In this case you may need to use a directly-connected laptop, or a different network to configure
the FBVi. Alternatively you could change the FBVi’s subnet mask to
10.ss.ss.ss/24
, (where
ss
is the
serial number) to reduce the size of the subnet that could give rise to conflicts. For example, a FBVi
with serial number
901001A
should have a subnet mask of
10.90.10.01/24
.
