Intermec 751G user manual Configuring the Computer in a UDP Plus Network

Chapter 3 — Configuring the Computer

The computer returns the CgS+BV4 transaction to the host application:

Cg is a TMF Configuration Get response.

$+ is the Change Configuration reader command.

BV4 means the Beeper Volume configuration command is set to a value of 4, which is a very high beeper volume.

Configuring the Computer in a UDP Plus Network

Use the host computer to configure a 751G in your wireless network. To send and receive configuration data or files, write a host application that can communicate with an Intermec Application Server (IAS) (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 751G.

To set up the IAS, configure a peer-to-peer destination name for the host application. Create a $NGCFGRSP transaction ID that routes to this destination name. The IAS uses the transaction ID to route responses from the 751G back to the host application. $NGCFGRSP is a special transaction ID that the server uses to forward configuration response data from a 751G.

All configuration responses are routed with the $NGCFGRSP transaction ID. The IAS cannot track multiple applications sending reader or configuration commands. If you have two host applications sending reader or configuration commands, they must both be configured to receive the $NGCFGRSP transactions, and receive all 751G responses.

To set up the host computer, verify host computer-to-IAS communication.

To set up the application, prepare and write a host application that can communicate with the IAS and send transactions to and receive transactions from the 751G in this format.

transaction header TMF field commands

where:

transaction is a 96-byte field with message number, date, time, source application ID,

header destinations application ID, transaction ID, and other. 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 751G to host computer.
CS	Configuration Set request sent from the host application.
Cs	Configuration Set response sent from the 751G to the host computer

commands are the reader and configuration commands to set on the 751G or the current value to retrieve from the 751G. To save configuration changes in flash memory, send the .+1 reader command as the last command. See the Intermec Computer Command Reference Manual for supported commands.
