AJAX ReX 2 User Manual page 5

The hub and ReX 2 must be connected to the same network through a router for
this communication channel to work. The router is needed to determine the IP
address for the range extender. The network to which ReX 2 connects must
allow broadcast queries and an open 4269 port for all types of tra c.
Connecting ReX 2 directly to the hub via an Ethernet cable is not provided.
ReX 2 can work with both static and dynamic IP addresses. If the range extender
is unable to establish an Ethernet connection with the hub, the
display a malfunction. For convenience, the MAC address of the range extender
is also available in the error details, which can be used to nd and solve the
problem.
A communication loss noti cation is sent in two cases: if the hub completely loses
connection with the range extender, and also if the hub loses connection with the range
extender via the photos transmitting channel. If communication via Jeweller only or via
Wings only is lost (when Ethernet is connected), a noti cation is not sent.
Support of photo veri cation
ReX 2 radio signal range extender supports connection of
veri cation . ReX 2 range extender can transmit not only events and alarms but
also photos taken by the detectors.
Photo delivery time via range extender depends on the channel of the
communication with a hub, the type of detector and the resolution of the
images.
