Mode. Once the RF Terminal transmits data to the Base Station, the Base Station acknowledges receipt of the information by echoing back the data to the Terminal that sent it, along with a beep. If the data transmission did not make it through to the Base station after 10 tries, the RF Terminal will give two long beeps and display the following message:

TRANSMISSION FAILED

AND PRESS ENTER.

F1 TO EXIT.

One-Way mode also works well as a test program since it doesn’t require a program running on the host computer or even that the Base Station be connected to the host. To get into One-WayMode:

Hit any key at the opening screen, then select option 3 from the MODE MENU.

If the Base Station already has other RF Terminals signed on in Two-Way mode, you will not be allowed into the system. A Base Station must be dedicated to one mode at a time.

If the Base Station is dedicated to One-Way mode, you will see the following prompt on the RF Terminal display:

Data Received Was

Enter Data?

Since you have just started your One-Way session, there is no data to display on line #2. Line #3 is now asking you to scan or key data into the RF Terminal. If you are entering data from the RF Terminal keypad, you must press the ENTER key to transmit your data. If the Base Station receives the data, the RF Terminal displays the following prompt:

Data Received Was aaaaaaaaaaaaaaaaaa Enter Data?

Where aaaaaaaaaaaaaaaaaa is the data received by the Base Station (and transmitted to the Host Computer if connected). You can exit One-Way Mode simply by pressing the F1 key on the RF Terminal keypad.

In One-Way Mode, the RF Terminal transmits its Terminal ID to the Base Station but it does not pass it on to the Host Computer. If your application on the Host Computer needs to know which RF Terminal data came from, use the Preamble setup parameter to enter unique identifying information. Data is also transmitted without a Terminator Character (like a CR or TAB that is transmitted after the data); so if you need one, use the Postamble setup parameter to add the appropriate character(s) after your data. For more information on Preambles and Postambles see Chapter 2; RF System Setup for details.

How Site Survey works

The 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 range without Site Survey.

Before you permanently install any hardware, you should perform a Site Survey to fully evaluate your planned area of operation. During the test the RF Terminal is transmitting messages and waiting for acknowledgment from the Base Station. (Since this US Terminal hops over 26 different frequencies, the Site Survey goes across all frequencies to make comparisons valid; this takes about 10 seconds.). The Site
