3. If the host program does nothing within 2 seconds, the Terminal displays the message:
Host Application Not Found
Enter: Retry or F1:Exit
Lets suppose that a Terminal and a host application program have been processing data by sending prompts
and data back and forth as described above. The host application program sends a data prompt to the
Terminal. The Terminal transmits the operator-entered data back to the Server. If the host application
program has another prompt for the terminal, it sends it out, repeating the process above. If the host
application program doesn't respond within 2 seconds, the Terminal Device displays
Host Application Not Found
Enter: Retry or F1:Exit
You might walk closer to an Access Point or you might simply hold the terminal up high over your head.
When you have repositioned the terminal, pressing the Enter key on the Terminal starts the transmission
process over again.
How Site Survey works
The Wi-Fi RF Terminal uses Site Survey mode to: 1) test the radios at short range, (50 ft.) as an acid test for
correct operation, and 2) to evaluate a specific site for effective coverage. Because each operating
environment is different, it is almost impossible to predict the performance without Site Survey.
Before you permanently install any hardware, you should perform a Site Survey to fully evaluate your
planned area of operation. Selecting option 3 from the main menu will start a Site Survey. The Wi-Fi RF
Terminal will listen for APs that are broadcasting SSIDs and display them along with the security type. This
information is useful to determine if an area has Wi-Fi coverage or not. It is a good idea to scan a few times
at each location since not all SSIDs may be heard by the radio on every scan.
This information will help you later when you are setting up the SSID and security type in the Setup screens
of the Wi-Fi RF Terminal.
Performance Issues
Evaluating your area of planned operation
Since every operational environment is different, it is impossible for us to tell you exactly what equipment
you need and where you should put it to achieve maximum performance from your RF System. However,
since access points are very inexpensive, you should be able to obtain whatever coverage you need. In a
typical warehouse, a terminal should be able to achieve communication within about 150 feet of an access
point. If you are planning the wiring of a new installation, you will want to lay out your access points so that
there is overlap.
There is also some basic information about Radio Frequency itself that can help you make smart choices about
the location and composition of your system:
