How the One-Way RF System works
The RF System can be used to perform “dumb” data entry to the computer – you
could even use Portkey to transmit the data as though it has been entered from
the keyboard. This is useful if you want to enter data directly into an application.
This type of data transmission is called One-Way 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
TO RETRY, MOVE CLOSER
AND PRESS ENTER.
F1 TO EXIT.
One-Way mode also works well as a “demo” program since it doesn’t require a
program running on the host computer or even that the Base Station be
connected to the host. If you want data to display on the host computer, simply
run a program such as Windows’ Terminal (be sure to disable Xon/Xoff) or our
Portkey program (for keyboard emulation). To get into One-Way Mode:
At power up, the RF Terminal asks if you want to
SIGN ON?
KEY [YES/NO]?_
SIGN ON is for Two-Way communication only. Press NO, then press NO again
at:
SETUP MODE?
KEY [YES/NO]?_
When you see:
ONE WAY MODE?
KEY [YES/NO]?_
Press YES. 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
