8. The connection between the GV-ASManager and GV-AS / GV-EV 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 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
(For details on adding a card, see Step 1 in 4.3.1 Adding a Single Card.)
It may be the card format is not compatible with the controller. For GV-AS100, GV-AS110 and
GV-AS120, ensure the format is 26~64 bits. Otherwise, send us the related information of
your card format so that we can customize the format for you.
