Wireless Light-Level Monitoring ILT1000
Wireless access point goes out of
range During this testing, a system restart was forced (Windows 8
equivalent of a BSOD) upon leaving the wireless range
while accessing the NUS device. This is likely a driver issue
related to use on Windows 8. Past testing has
demonstrated the behavior on Windows XP, but not on
Windows 7. This is likely an issue related to the
combination of system, OS-version, and driver. If the
wireless range is lost and re-gained while the NUS device is
not being accessed, the restart does not occur. The
workaround is to ensure that wireless connectivity is
maintained while accessing the NUS device.
Monitoring station/computer
returns from power down mode. With “Connect Device Automatically” is selected (See
Figure 15), the ILT1000 is automatically connected when
returning from low-power mode.
Reboot of the monitoring
station/computer. With “Connect Device Automatically” is selected (See
Figure 15), the ILT1000 is automatically connected upon
start-up or reboot.
Summary:
- Pros
o
Works as advertised, with the combination of the wireless router and Ethernet-USB
Bridge providing robust wireless-to-USB bridging and supporting the ILT1000.
o
Can be configured to automatically re-connect ILT1000’s after reboot and return
from low-power modes.
o
Simple installation and setup.
o
1 reading/second sampling, which is likely good enough for most remote monitoring
applications.
- Cons
o
Each Monoprice/Winstars NUS device can handle a maximum of 4 USB devices
connected to it. To expand beyond 4, multiple NUS devices are required.
o
Potential system restart requirement, based on the specific configuration tested,
while accessing the USB device when network connectivity is lost.
Conclusion
The ILT1000’s industry-standard USB interface, combined with the many network-to-USB
bridging solutions on the market, allows simple, low-cost methods to create wireless light-level
monitoring solutions. This capability opens up the possibility for robust, continuous monitoring
and alerting, particularly in applications where environmental safety may be compromised by
light levels that are either too low or too high.
