You can also allow or deny remote control keyboard access to message files transmitted to the Alpha 7120C N4/N4X by computer.
• Non-Blinking String File Updates – The Alpha 7120C N4/N4X supports "String Files" and real-time updating of String Files without blinking the messages displayed on the sign. String files are memory areas set aside in sign memory by special programming. One use of String Files is to store changing data being updated by an external device or computer. For example, the Alpha 7120C N4/N4X could be programmed to display five (or more) statistics fields for each of five (or more) production lines. As the real time values change for each of the 25 variables (5 x 5), the updated values can be transmitted into the Alpha 7120C N4/N4X instantly, without causing the Alpha 7120C N4/N4X to blink and without affecting the information currently being displayed. String Files can also be used to save sign memory. For example, if the same data is displayed multiple times within a message, the data can be stored once in a String File and recalled from its String File location each time it is needed.
• Nested Commands – For programmers writing control sequences using native sign communication protocol, multiple commands can be repeated or "nested" within a transmission frame.
• Clear Memory Easily – When debugging and testing software and messages features, the remote control keyboard can be used to clear the memory of the sign quickly and conveniently, without opening the Alpha 7120C N4/N4X enclosure or taking it down from where it is mounted. Clearing memory removes all messages, graphic files and the password that have been programmed into the Alpha 7120C N4/N4X.
