Intermec cn30 User Guide

The default reference time server is the USNO (tock.usno.navy.mil). To 
synchronize the time on your CN30 with this time server, you must have a 
valid connection to the Internet. You can also synchronize the CN30 Com-
puter system time with a corporate network server within your firewall that 
is SNTP-capable. To use an internal corporate network server, you need to 
set the command name in the registry.

You can change the configuration parameters of the CN30 Computer by 
sending commands through a host computer or through the network. If 
you are using a network, you can configure one or more CN30 Computers 
at a time. You can remotely configure the wireless or Ethernet CN30 Com-
puter by sending a command from an application on the host computer. 
Note that you cannot set all parameters through the network. You can only set 
those commands that have a syntax in the Command Reference Manual.

You can use the host computer to configure a wireless or Ethernet CN30 
Computer in your TCP/IP network. To send and receive configuration 
data, you need to write a host application that can communicate with the 
CN30 Computer directly through an access point or through the Ethernet 
network. Use the TMF protocol to send and receive transactions between 
the host application and the CN30 Computer.

To set up the host computer, verify that you can communicate with the 
CN30 Computer. To set up the application, prepare and write a host appli-
cation that can communicate with the Intermec Application Server and 
send transactions to and receive transactions from the CN30 Computer in 
this format:

Note: You can continue running an application on the CN30 Computer 
while configuring it from the host computer.
