The TTY interface initial configuration screen
The TTY interface is the NetGuardian-16S's built-in controller for basic configuration and monitoring of the
NetGuardian-16S. Configure the NetGuardian-16S's ethernet port settings, monitor the status of base and system
alarms, operate control relays, view live ping targets , view debug or create proxy connections to other ports. For
more advanced configuration tools, please use the Edit16S utility.
To use the TTY interface with the NetGuardian-16S, all you need is any PC with terminal emulation software
(i.e. Hyperterminal) and a connection to the NetGuardian-16S. This connection can be a direct connection to the
NetGuardian-16S's top front panel craft port or a remote connection via Telnet or dial-up.
Some initial software configuration must be performed before you can use a remote connection to the
NetGuardian-16S. For Telnet, connect to the Net Guardian's IP address at port 2002 to access the configuration
menus after initial LAN/WAN setup.
Telnet sessions are established at port 2002, not the standard Telnet
port
as an added security measure.
The TTY interface is primarily used for configuring and provisioning the NetGuardian-16S, but you can also use
it to ping IP targets, view system statistics, and data port activity.
NOTE:
The TTY default password is "dpstelecom".
If you have physical access to the NetGuardian-16S,
the easiest thing to do is connect to the unit serially
through the top craft port and then assign it an IP address. Then you can complete the rest of the unit
configuration over a remote LAN connection, if you want. For instructions, see Section 12, "Connecting to the
NetGuardian-16S via Craft Port."
If you DON'T have physical access to the NetGuardian-16S,
you can make a LAN connection to the unit by
temporarily changing your PC's IP address and subnet mask to match the NetGuardian-16S's factory default IP
settings. Follow these steps:
1. Look up your PC's current IP address and subnet mask, and write this information down.
2. Reset your PC's IP address to
192.168.1.200
