Configuring the CK60 Computer in a UDP Plus Network
You can use the host computer to configure a CK60 Computer in your
wireless or Ethernet network. To send and receive configuration data or
files, you need to write a host application that can communicate with an
Intermec Application Server (formerly Gateway or DCS 30X).
For help, see the appropriate Gateway or DCS 30X User’s Manual. Use the
Terminal Message Format (TMF) protocol to send and receive transactions
between the host application and the CK60 Computer.
To set up the Intermec Application Server, configure a peer-to-peer desti-
nation name for the host application. Create a transaction ID, $NGCF-
GRSP, that routes to this destination name. The Intermec Application
Server uses the transaction ID to route responses from the CK60 Computer
back to the host application. $NGCFGRSP is a special transaction ID that
the server uses to forward configuration response data from a CK60.
All configuration responses are routed with the $NGCFGRSP transaction
ID. The Intermec Application Server cannot track multiple applications
sending reader or configuration commands. If you have two host applica-
tions sending reader or configuration commands, they must both be con-
figured to receive the $NGCFGRSP transactions, and therefore both
receive all responses from all CK60 Computers.
To set up the host computer, verify that the host computer can communi-
cate with the Intermec Application Server.
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 Computer in this format. For an
example of the host application transaction, see page 51.

transaction header TMF field commands
transaction
header
is a 96-byte field with message number, date, time, source application
ID, destinations application ID, transaction ID, and other information.
Set the system message (SYS$MSG) flag to E in the transaction header.
TMF field is a 2-byte field containing one of these values:
CG Configuration Get request sent from the host application.
Cg Configuration Get response sent from the CK60 Computer to
the host computer.
CS Configuration Set request sent from the host application.
Cs Configuration Set response sent from CK60 to host computer
commands are the reader and configuration commands that you want to set on the
CK60 Computer or the current value you want to retrieve from the
CK60 Computer. To save configuration changes in flash memory, send
the reader command .+1 as the last command. See the Command
Reference Manual for a list of supported commands.
