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 Testing works

The RF Terminal uses Site Test 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 Testing.

Before you permanently install any hardware, you should perform a Site Test to fully evaluate your planned area of operation. During the test the RF Terminal is transmitting messages and waiting for acknowledgement from the Base Station. (Since this US Terminal hops over 25 different frequencies, the Site Test goes across all frequencies to make comparisons valid; this takes about 10 seconds.) The Site Test evaluates the percentage of successful transmissions. The higher the percentage, the more successful your communications will be from that area. Site Testing does not require your Base Station be attached to your Host Computer. All you need is your Base Station, 5v power supply and RF Terminal. For detailed information

on how to perform a Site Test and use the results to determine the best location for your Base Station, go to Chapter 4; Performance Issues.
