RF Configuration
Default settings are shown in bold type.
The RF Terminal will typically require no setup changes except, Terminal ID (if more than one terminal) and enabling bar codes to be read other
than UPC or Code 39.
RF Terminal ID
Default ID
Available IDs

Every terminal needs a unique Terminal ID. The default Terminal ID is always shipped as 0. If you have more than one RF
Terminal assigned to a Base Station, you must be sure that each RF Terminal has a unique Terminal ID, (otherwise you will
have big troubles including false error messages). The Terminal ID is always displayed on the Start Up screen when you
power up the terminal. There are 64 Terminal IDs available - 0-9, A-Z, a-z, and the special characters "-" and "=". To change
the Terminal ID, select option 2 on the keypad after which a box will appear where you can enter the desired Terminal ID.
Enter one character for the Terminal ID.
RF Terminal Channel
Default Channel

The terminal's radio operates by "frequency hopping" spread spectrum. The radios hop from one frequency to another using a
pseudo-random sequence. The radio goes through 26 different frequencies and then repeats the sequence – all in the 902-928
MHz band at 250 milliwatts of power. Different sequences define the channels. It is possible to have more than one RF Network
in the same area, providing each RF Network is on separate channels to avoid interference and general confusion.

The default Channel is always shipped as 0. There are 6 channels in the USA. The Channel can be set by pressing the 1 key
when in the RF Configuration menu. Each time you press the 1 key the Channel will increment through the 6 possible channels.
All Terminals, Base Stations and Relays in the RF Network must be set to the same channel. The channel is always displayed on the
Start Up screen when you power up the Terminal. It is possible to have more than one RF Network in the same area, providing each
RF Network is on separate channels to avoid interference and general confusion.
Security Code
Security Code
Available security codes

A Security Code can be utilized to minimize the possibility of a Base Station listening to data from a Terminal that is talking to
a different Base Station. A Security Code can also prevent interference from having many Base Station/RF Terminal configura-
tions in one area; i.e. a merchandise mart with multiple vendors all running RF Terminal networks.

A Security Code consists of 3 characters - any combination of ASCII 33 - ASCII 126. This allows for the possibility of more
than 830,000 different character combinations. The characters are entered using the bar coded FULL ASCII MENU provided in
Appendix O; ASCII Code Equivalent Table.

Once you press 3 to enable the Security Code, you will see 3 boxes appear where you can enter the desired security code. Press-
ing the CLEAR key will reset the Security Code to the default value which is OFF. You can enter any key on the keypad. If you
press the shift key the cursor will turn RED and you can enter any of the shifted values on the keypad.

You must also enter a matching security code into the the Base using the Hardware Utilities program.
To enter characters that are not on the keypad, use the FULL ASCII MENU provided in Appendix O.
Skip Opening Screens

Go to Two-Way (TWO WAY)
Go to One-Way (ONE WAY)

Many users want to skip the opening screens and go directly to TWO WAY or ONE WAY communication once their pro-
grams are fully operational. Selecting TWO WAY or ONE WAY will automatically take the operator to the corresponding
mode and into your application, skipping the usual Mode Menu. If you want to return to the Mode Menu at any time, simply
press the F1 key.
