Honeywell IP Communicator Bandwidth & Port Info

7845i-ENT is a T10 based device half duplex
7847i is a T10/100 base device half duplex
7845iGSM is a T10/100 base device half duplex
Vista21IP is a T10/100 base device half duplex

Devices communicate outbound to one of three predet
ermined IP addresses on port 443 and all data is en
crypted use AES encryption.
Devices are capable of using DHCP or Static IP

Devices in the field send a MAC ping out on port 44
3 every 20 seconds.

All inbound and outbound traffic between the Device
and AlarmNet NCC is fully encrypted

Each device MAC has a unique encryption key in it a
nd AlarmNet has the matching key at it’s NCC no ke
y is transmitted between the two points.

For a session to occur the end user logs into a sec
urity HTTPS web site that is hosted at the AlarmNet
NCC. Once the device checks in we tell the
device to establish a socket connection with a serv
er at a predefined IP address based on what functio
n the end-user is requesting.
The use of this method allows the device to establi
sh connection outbound but we can not establish a s
ession inbound to the device.

The device is operating with a private written code
set and is not vulnerable to attack by hackers or
virus.
