This article demonstrates how to enable the Telnet password and secure the D6686 IPv6 Communicator from Internet based attackers, attempting to utilize the second available tunnel.
How to return the D6686 to factory settings.
How to determine the values to enter for the Poll Rate and Ack Wait Time.
Note: The calculation described is only be required on legacy control panels. The B8512G/B9512G and GV4 types only need a Receiver Supervision Time selection. The Poll Rate, Ack Wait and Retry count will automatically populate.
The formula for determining Poll Rate and Ack Wait Time is as follows:
Panel setting: Poll Rate + Ack Wait + ( Retry Count X Ack Wait)
Receiver setting: Panel Poll + Ack Wait
Panel setting = Receiver setting
Example: Panel Setting: Poll Rate = 240; Ack Wait = 10; Retry Count = 5 Panel setting: 240+10+ (5 X 10) = 300
Receiver Settings: Poll = 240; Ack = 60 Receiver setting: 240 + 60 = 300
300 = 300 Refer to the the following site for more information on setting up Conettix Devices
