5. Q&A
2)Is it possible to connect NSA-Ux using external Hub device?
ÆNSA-Ux is bus-powered USB device. Bus-powered devices rely totally on power fro
m the USB cable. The power consumption of NSA-Ux is 160~185mA. So, if notebook c
omputer run short of battery power, NSA-Ux will not work properly. In addition, it is r
ecommended that NSA-Ux is directly connected to USB port of notebook or PC withou
t extra hub or else.
1) How do I change the virtual COM port number assigned by the USB to Seri
al Port Driver?
ÆAfter the driver is installed, it will create a virtual COM port and the default setting
assigned by the OS will be COM2 or COM3 if there are two physical COM ports on your
computer. If you want to change the assigned virtual COM port for the NSA-Ux to the
other COM port, please follow the steps below.
-Double click My Computer, Control Panel, System
-Click Device Manger tab
-Click Ports(COM&LPT) and double click on the NAVIUS USB to Serial Port (COM
x)
-Click Port Settings tab and click Advanced button
You can change the virtual COM port to the other one at the COM port combo box.
3)After disconnecting NSA-Ux from USB port, I connect NSA-Ux to USB port
again. Why I cannot see any incoming data in HyperTerminal?
ÆWhen NSA-Ux is removed, Virtual COM port will be disappeared. Hyperterminal can
not reconnect COM port automatically. In Hyperteminal, Simply press disconnect butto
n and connect button again.
4)When I connect NSA-Ux, there is some delay to see incoming data. Why is
that?
ÆTo avoid Bluescreen problem in Windows XP, NSA-Ux outputs data after 5 seconds.
