• 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 configurations 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 with the RF Terminal. See Appendix O;
ASCII Code Equivalent Table for the correct corresponding characters.
• Once you press 1 to enable the Security Code, you will see the following
prompt on the Terminal:
Enter Security Code_
You will be able to see the code as you enter it on the Terminal but once you
have moved on to another Setup Parameter, you will only see the status; 0
(disabled) or 1 (enabled) if you go back to it.
• If you forget the Security Code that you have already used on other
Terminals, the only way to see the code is to go into the Base Setup. This
requires that you have full access to the Base Station in order to change the
programming jumper. See Chapter 2 for Base Station Setup.
• You can only access the Security Code setup parameter by going into Setup
Mode via the RF Terminal keypad but you must use the bar coded FULL
ASCII MENU to scan in ASCII characters 33-126.
