Example
In the host application, you want to get the current values of two configura-
tion commands from the CN30 Computer. Send the 
CG$+NABV
 transaction 
from the host application
where:
The CN30 returns the 
CgS+BV4
 transaction to the host application, where:
Configuring the CN30 Computer in a UDP Plus Network
You can use the host computer to configure a CN30 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 CN30 Computer.
To set up the Intermec Application Server, configure a peer-to-peer destina-
tion name for the host application. Create a transaction ID, $NGCFGRSP, 
that routes to this destination name. The Intermec Application Server uses 
the transaction ID to route responses from the CN30 Computer back to 
the host application. $NGCFGRSP is a special transaction ID that the 
server uses to forward configuration response data from a CN30.
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 CN30 Computers.
To set up the host computer, verify that the host computer can communi-
cate with the Intermec Application Server.
Note: The transaction header is not shown in this example. You do not 
need a transaction header for a host application in a TCP/IP network, but 
you do for a UDP Plus network.
CG
is a TMF Configuration Get request.
$+
is the Change Configuration reader command.
BV
is the Beeper Volume configuration command.
Cg
is a TMF Configuration Get response.
$+
is the Change Configuration reader command.
BV4
means the Beeper Volume configuration command is currently set to a 
value of 4, which is a very high beeper volume.
