8. The connection between the GV-ASManager and GV-AS Controller should be
established, and the connection icon should appear. If disconnection happens after
you connect the hub or switch to the network, then it should be other network problems.
Please contact your network administrator.
Q3: GV-ASManager cannot receive card messages but the reader accepts the
card when the connection between the GV-ASManager and GV-AS / GV-EV
Controller is well established.
It may be due to memory failure in the GV-AS / GV-EV Controller. Reset both the controller
module and the Ethernet module to factory settings. Refer to Step 3 in Question 1.
Q4: The GV-ASManager cannot retrieve the video from the DVR for playback.
1. Make sure the
Remote ViewLog Service
on
Control Center Server
is enabled on the
DVR.
2. Make sure the time on the GV-ASManager and the DVR is consistent.
3. Make sure the event file you want to play back has been created completely on the DVR.
For example, the assigned time length of every recorded event on the DVR is 5 minutes.
The desired event of 5 minutes must have been displayed on the ViewLog Event List, so
you can access the event file for playback.
Q5: After I add a card by presenting to the reader, the message “
Access
Denied Invalid Card” still appears.
It may be the card format is not compatible with the GV-AS / GV-EV Controller. Make sure
the card format is 26~64 bits. Otherwise, send us the related information of your card format
so that we can customize the format for you.
