Ensure LAN CAT5 cable is connected to the POE on the Power adapter and all other
connections are complete.
Ensure HazSim and Computer are charged
Turn off Server and HazSim, unplug and replug LAN being sure Cat5 cable is plugged in to
POE, turn on Server, then turn on HazSim.
Interference with Connection - on rare occasions with Pro 1 the system would not
connect where there was a large radio transmission tower. Physical barriers may cause
signal degradation, causing signal loss, Poor LAN antenna placement, RF Interference
Power loss to LAN antenna, CAT5 Cable plugged into LAN and not POE. If this is suspected,
move to an area where there was no trouble with connection and retest. Contact HazSim
support.
System server settings changed - If you have an early edition or using your own
computer as a server and the settings were changed, contact HazSim support.
Maximizing Range
PRO Tip: It is important to check your range obstacles prior to beginning your training
session. In general if the instructor can see the LAN, and the LAN can ‘see’ the students with
the HazSim, the range should be good. If you are training in an area with thick concrete or
steal, several feet below grade, reinforced vaults, or reinforced ships.
I. LAN in raised position
Raising the LAN to a height which has an overview of the training ground can greatly
extend the range of the HazSim system. If you can ‘see’ the LAN from both the
HazSim position and the Server position this will maximize range. A longer CAT5
cable can be used to extend the height of the LAN being sure to plug in to the POE
port on the LAN power adapter.
II. Overcome obstacles
The signal is similar to any other radio device where lightweight constructed walls will not
pose too much interference. Thick wall reinforced construction or thick metal walls as
found in some training props will restrict the signal. To overcome these obstacles set up
the LAN near an entrance if possible, with the best view of both the HazSim and the
Instructor. Consider the elevated approach as some construction will have thick walls but
lightweight roofing enabling the signal to reach from above.
