Chapter 3 — Configuring the Computer
CK60 Handheld Computer with Windows Mobile User’s Manual 93
Synchronizing the Computer System Time with a Time Server
It is important that the time on all of your CK60s be synchronized with a
network time server to ensure real-time communications and updates.
Network time servers acquire Coordinated Universal Time (UTC) from an
outside source such as the U.S. Naval Observatory (USNO). The CK60
uses Simple Network Time Protocol (SNTP) to synchronize with a
network time server.
The default reference time server is the USNO (tock.usno.navy.mil). To
synchronize the time on your CK60 with this time server, you must have a
valid connection to the Internet. You can also synchronize the CK60
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.
Configuring the Computer through the Network
You can change the configuration parameters of the CK60 by sending
commands through a host computer or through the network. If you are
using a network, you can configure one or more CK60s at a time. You can
remotely configure the wireless or Ethernet CK60 by sending a command
from an application on the host computer.
Configuring the Computer in a TCP/IP Direct Connect Network
You can use the host computer to configure a wireless or Ethernet CK60 in
your TCP/IP network. To send and receive configuration data, you need to
write a host application that can communicate with the CK60 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 CK60.
To set up the host computer, verify that you can communicate with the
CK60. To set up the application, prepare and write a host application that
can communicate with the Intermec Application Server and send
transactions to and receive transactions from the CK60 in this format:
Note: You cannot set all parameters through the network. You can only set
those commands that have a syntax in the Intermec Computer Command
Reference Manual.
Note: You can continue running an application on the CK60 while config-
uring it from the host computer.
