The auto-sensing 10/100 kbps Ethernet
in/out ports fitted to each Xpyda module allow a range
of configurations to be used:
1. Simple connection of Xpyda direct
into the nearest Cat. 5 RJ45 network port, and the
Xpyda then monitors up to 5 sets of alarm inputs on
that port (this configuration uses any available,
free network port);
2. As per 1. but the Xpyda sits
in line between the network point and a device already
present on the network (e.g. a PC or laptop, IP-camera,
network printer, etc.) (this configuration uses an
existing port into which a pre-existing device is
already plugged);
3. As per 1. or 2. but where two
or more Xpydas are connected together in series to
the same existing network port regardless of whether
this is already in use.
4. Any combination of network configurations
1, 2 and 3 as required.
With three possible network configurations
plus up to 5 items protected per Xpyda module (as shown
above), the scope and flexibility of Xpyda is limited
only by the total network resources available on any
given site rather than by any limitations of the Xpyda
hardware or software.
With reference to PoE networks (click
here for more information), the only restriction
is that the equipment terminating the network connections
under configurations 2 and 3 must not be PoE equipment.
Cable lengths
Computer cable:
Xpydas should be connected to the TCP/IP network following
the same wiring regulations which apply to all IT networked
equipment.
Alarm cable: The
maximum length of alarm cable supplied for use with
Xpyda modules is 20 metres. Cable should be installed
observing the standard specifications for analogue alarm
and signalling cabling
