General FAQs
16.1
Q. How do I telnet to the NetGuardian LPG Controller?
A.
You must use
Port 2002
to connect to the NetGuardian LPG Controller. Configure your Telnet client to connect
using TCP/IP (
not
"Telnet," or any other port options). For connection information, enter the IP address of the
NetGuardian LPG Controller and Port 2002. For example, to connect to the NetGuardian LPG Controller using
the standard Windows Telnet client, click Start, click Run, and type "telnet <NetGuardian LPG Controller IP
address> 2002."
Q. How do I connect my NetGuardian LPG Controller to the LAN?
A.
To connect your NetGuardian LPG Controller to your LAN, you need to configure the unit IP address, the subnet
mask and the default gateway. A sample configuration could look like this:
Unit Address:
192.168.1.100
subnet mask:
255.255.255.0
Default Gateway:
192.168.1.1
Save your changes by writing to NVRAM and reboot. Any change to the unit's IP configuration requires a reboot.
Q. When I connect to the NetGuardian LPG Controller through the craft port on the front panel it either
doesn't work right or it doesn't work at all. What's going on?
A.
Make sure your using the right COM port settings. Your COM port settings should read:
Bits per second:
9600 (9600 baud)
Data bits:
8
Parity:
None
Stop bits:
1
Flow control:
None
Important!
Flow control
must
be set to
none
. Flow control normally defaults to hardware in most terminal
programs, and this will not work correctly with the NetGuardian LPG Controller.
Q. The LAN link LED is green on my NetGuardian LPG Controller, but I can't poll it from my T/Mon.
A.
Some routers will not forward packets to an IP address until the MAC address of the destination device has
been registered on the router's Address Resolution Protocol (ARP) table. Enter the IP address of your gateway
and your T/Mon system to the ARP table.
