3.2.2 Cables
Atracsys does not supply cables with the fusionTrack system, as standard Cat 5e Ethernet cables can be
used. The usage of shielded and unshielded cables are possible. In case a
PoE
+ power supply is used,
two Ethernet cables are needed (one from the host PC to the
PoE
+ power supply and one from the
PoE
+
power supply to the fusionTrack device). The
PoE
+ power supply needs a main power cable.
Power over Ethernet is a quite complex standard that includes an initialisation phase where the
PD
(here fusionTrack device) negociates with the
PSE
(here the
PoE
+ power supply respectively the
PoE
+
router) the amount of power needed. Depending on the
PSE
, the cables used (shielded or un-shielded) and
even potential ground loops between the
PSE
and the computer, this negociation phase might fail i.e. the
fusionTrack device will not receive power.
This potential problem can be avoided when the following recommendations are respected:
- Using a passive Gigabit Midspan Injector and an appropriate DC power supply (see Section 3.2.1). In
this case, no negociation phase takes place and it is always guaranteed that the fusionTrack receives
power. Both shielded and unshielded cables work perfectly;
- Using a
PoE
+
PSE
. In this case, the usage of unshielded cables (before and after the
PSE
) presents
less problems. Ground loops between the
PSE
and the PC have to be avoided i.e. the main power
connections of the
PSE
and the PC have to be connected together in the same wall plug respectively
in the same multiple socket outlet.
3.2.3 Status LEDs
The status LEDs colour and behaviour is used to indicate the status of the fusionTrack device. When the
fusionTrack device is switched on, the boot sequence starts with tests, during which the LEDs are switched
on and off, with various colours. This lasts for about 20 s to 30 s, then the LED is used to indicate the status
of the device. The various states are explained on Table 3.4.
3.3 The fusionTrack software development kit
The fusionTrack software development kit (
SDK
) is used to retrieve the measurements from the fusionTrack
on the PC and to modify settings on the fusionTrack. It is completely documented in an annex document [1].
3.4 Authorised modifications
Strictly no modifications are allowed on the fusionTrack nor on the fusionTrack SDK. The fusionTrack device
shall not be opened. If repairs or modifications are needed, please either contact or send the device back
to Atracsys (Section 1.6).
