Configuration Methods
The IAP Device Server can be configured using remote or local methods. Either use
an ASCII terminal or a terminal emulation program to locally access the serial port, or
use a Telnet connection to port 9999 to configure the unit over the network. See the
Getting Started chapter of the User Guide for your IAP Device Server.
The IAP Device Server configuration is stored in nonvolatile memory and is retained
without power. The configuration can be changed any time. The IAP Device Server
performs a reset after the configuration has been changed and stored.
IAP Device Server’s IP Address
The IAP Device Server is shipped with a default IP address of 0.0.0.0, which
automatically enables DHCP within the IAP Device Server.
With a DHCP-enabled IAP Device Server, if there is a DHCP server to respond to
IAP Device Server’s request when it is booting up, the IAP Device Server will then
get an IP address, a gateway address, and a subnet mask from the DHCP server.
These addresses will not be shown in the IAP Device Server’s Setup (configuration)
screens (you will still see 0.0.0.0); however if you enter the Monitor Mode and from
0> prompt, type NC (upper case), the IP configuration of the IAP Device Server will
display. (See 3: Monitor Mode and Firmware Upgrade.)
Using the Setup Mode Screen
1. From the DeviceInstaller configuration utility, click the Telnet button to open
a Telnet connection to the IAP Device Server. The IAP Device Server’s Ethernet
hardware address (or HW MAC) displays.
Serial Number 6407487 MAC address 00:20:4A:64:1D:3F
Software version 01.3 (010317)

screen. Here you can change the parameters that define how the IAP does its
job.
Note: When you set up a new unit, and especially if you just reflashed
the unit with a new firmware type, we recommend that you reset all of the
parameters to the factory defaults.
3. To reset the parameters to the factory defaults, type R on the command line and
press Enter. The default parameters display.
