6: Getting Started
This chapter covers the required steps to get the Device Server on-line and working. There
are two basic methods used to log into the Device Server and setup the IP address:
!
Network Port Login: Make a Telnet connection to the network port (9999).
!
Serial Port Login: Connect a terminal or a PC running a terminal emulation program
to the Device Server’s first serial port (CH 1).
It is important to consider the following points before logging into and configuring the
Device Server:
!
The Device Server’s IP address must be configured before a network connection is
available.
!
Only one person at a time may be logged into the network port. This eliminates the
possibility of several people simultaneously attempting to configure the Device
Server.
!
Network port logins can be disabled. The system manager will not be able to access
the unit. This port can also be password protected.
!
Only one terminal at a time can be connected to the serial port. (In RS-485 mode,
the Device Server is capable of multidrop connections.)
Default IP Address
The Device Server ships with a default IP address set to 0.0.0.0, which automatically
enables DHCP within the Device Server.
Provided a DHCP server exists on the network, it will supply the Device Server with an IP
address, gateway address, and subnet mask when the Device Server boots up. (If no DHCP
server exists, the Device Server will respond with a diagnostic error: the red Diagnostic
LED blinks continuously and the green Status LED blinks five times.)
This IP address will not appear in the Device Server’s configuration screens; however, if
you enter Monitor Mode from the serial port with network connection enabled (see Monitor
Mode on page B-1), and issue the NC (Network Connection) command, you will see the
Device Server’s IP configuration.
