If you set network with Modem (PPPoE connection), networking works only via Modem-to-modem. In the same

manner, if you set network with LAN, networking works only via LAN. So, it is impossible to use LAN and modem at

the same time.

3. I have a firewall on my network system. It is impossible to normally interface with internal

XDVR server via external client S/W.

In case of system with a

firewall, you need to open the ports to interface with internal QLR1660 server via

external client S/W or search S/W. The ports are set at System setup of the Environment Setup of QLR1660 server.

Please open the following ports: 2000, 2001, 2002 and 2003 (default ports).

Some mother-board of VIA chipset could impact with the QLR1660 server system.

6. Although I reinstalled the QLR1660 program, the Setup of QLR1660 system is not set to factory-defaults.

Although uninstall the QLR1660 program, LOG and CFG files may affect the QLR1660 system installed newly still left

over in program folder. (C:\ProgramFiles\ VISTAPRO \) Therefore, after uninstall, must delete these all files left over by

all means.

In case that HDD Overwrite is set to enable (On), whenever free space is under 500MByte, QLR1660 system creates

the free space of 2.0GByte by erasing oldest data to save new recording data. But, if the total capacity of recorded data

for QLR1660is smaller than 2.0GByte, recording could be stopped. Please make the new space for recording.
