indicates a good network connection.
• Ensure the Ethernet connection light on the D6680 for the PC
running D6200 Software is on. This indicates a good network
connection.
• If using the D6600’s COM4 to connect to the D6680, ensure
Menu Item 6.1.4 COM4 Network Adapter in the D6600 is set

D6600 Menu Items 6.4.1 IP Address 1, 6.4.2 IP Address 2, or
6.4.3 IP Address 3.
• If communicating over a WAN, the external IP address of the
LAN with the PC running the D6200 software must be entered
into the D6600’s Menu Items 6.4.1 IP Address 1, 6.4.2 IP
Address 2, or 6.4.3 IP Address 3.

address of the D6680 is entered correctly.
— If communicating over a WAN, ensure the external
IP address of the LAN with the D6680 is entered.
— Both port numbers match (valid ports are from
2001 to 9998).
• If encryption is enabled on the D6200,
— it must also be enabled on the D6680.

• If communicating over a WAN, the firewalls of the LANs must
be configured correctly.
For example, the D6680 resides on one LAN while the D6200
software resides in another LAN. A WAN connects them both
but the firewalls at either LAN need to allow TCP and UDP
packets through.
• Firewalls must allow your selected ports to pass through.
• Contact your IT administrator.
