  • Automode – Characters enter, display and exit under control of randomly selected display modes.
  • Roll (Up, Down, Left, Right, In, Out) – Characters move onto the display down from the top (Roll Down), up from the bottom (Roll Up), from the right end to the left (Roll Left), from the left end to the right (Roll Right), move into position vertically from the top and bottom (Roll In), move into position vertically, entering from the center horizontal row (Roll Out).
  • Wipe (Up, Down, Left, Right, In, Out) – Characters are revealed as each horizontal row or vertical column of pixels is lighted row by row or column by column – from the top row of the character down (Wipe Down), from the bottom row of the character up (Wipe Up), from the left column of the message to the right (Wipe Right), from the right column of the message to the left (Wipe Left), from the center row of the message up and down (Wipe Out), or from the top and bottom rows of the message to the center row (Wipe In).
  • Scroll – Characters move up onto the display from the bottom, and any displayed characters move up and off the display.
  • Rotate – Characters travel from right to left across the display in the familiar stock market ticker display mode.
  • Condensed Rotate – Characters travel from right to left across the display in a horizontally-compressed font in the familiar stock market ticker display mode.
  • Hold – Characters display without effects or motion for a specified length of time. The length of time the message stays on the screen is determined by the Speed code.
  • Flash – All characters blink on and off simultaneously several times.
  • Twinkle – The pixels of the displayed characters oscillate their intensity.
  • Sparkle – New characters appear as their pixels turn on randomly and pixels in existing characters randomly turn off.
  • Snow – Lighted pixels sprinkle down from the top pixel row, building new characters from the bottom up, like accumulating snow.
  • Interlock – The 2nd, 4th, and 6th horizontal rows of pixels in the characters move rapidly from the left end to the right, while the 1st, 3rd, 5th, and 7th horizontal rows of pixels move rapidly from the right end to the left, forming the message on the display.
  • Switch – Every other character, i.e., the 1st, 3rd, 5th, 7th, 9th, etc., moves onto the display from the top down, as the remaining characters move onto the display from the bottom up, pausing momentarily to display the message.
  • Cycle Color – Each horizontal row of pixels in the message phrase is displayed in a color that changes four times a second, followed by a momentary pause, displaying the message phrase in one of the six color patterns – red, green, yellow, rainbow1, rainbow2 or mix.
  • Starburst – Several star-patterns display randomly, then form new characters, replacing any previously displayed characters.
• 6 Speeds – The Alpha 420C N12 has six Speed codes that control how long characters stay on the display in Hold mode, how long characters stay on the screen in the various Roll and Wipe modes, Interlock mode, Switch mode, etc. The fastest speed code is used with Hold mode to create user-designed animation effects.
• 10 Built-in Animations – The Alpha 420C N12 has ten built-in graphic animations that can be inserted into messages as special effects:
  • Cherry Bomb – The fuse on a cherry bomb burns down, and the bomb explodes.

  • Thank You – "Thank You" is written in script from left to right.
  • Welcome – "Welcome" is written in script from left to right.
• Automatic Message Centering – Messages are automatically centered on the Alpha 420C N12 display in all display modes, except when the Fixed Characters code is used. The Fixed Characters code left-justifies messages, and uses fixed (equal) character spacing from left to right. The primary use of the Fixed Characters code on the Alpha 420C N12 is to display similar fields of data on consecutive screens in the same pixel positions.
• Display Graphics – The Alpha 420C N12 will display user-designed graphics and logos, up to 7x120 pixels each, with your messages. You can create and store graphics in the Alpha 420C N12 using the remote control keyboard, or you can use a computer and special software. Using a computer, compose or scan bitmap (.bmp) graphics and save the bitmap files on disk. Then use software, such as AlphaNet Plus or Smart Alec, to send messages and graphics to the Alpha 420C N12.
• Real-Time Clock – The Alpha 420C N12 has a built-in, battery backed up real-time clock. The time and date (day, month, year) can be set using either the remote control keyboard or using a computer with software that sends the computer?s time and date to the Alpha 420C N12. The day, date and time are retained in Alpha 420C N12 memory for up to two weeks when the unit is unplugged.
• 12- or 24-Hour Time Display – The Alpha 420C N12 can display the time of day in either 12-hour or 24-hour format.
• 5 Counters – The Alpha 420C N12 will automatically count up or down in any increment, updating every minute, hour or day. Up to five different counters may be active in your messages at the same time. Counting may begin at any value between 0 and 99999999. Messages can display the number of days, minutes or hours until a special event; the number of days or hours since a lost-time accident; or a numeric value that increments or decrements by the same amount every minute, hour or day.
• Target Messages – Upon reaching specified Counter "target" values, specific target messages can be displayed automatically. For example, a message might display "10 DAYS WITHOUT AN ACCIDENT!" and on the next day automatically display "11 DAYS WITHOUT AN ACCIDENT!" followed by the target message: "A NEW RECORD... CONGRATULATIONS!"
• Computer Connection – The Alpha 420C N12 may be attached to a wide variety of computers, control equipment and communication devices.
• Supports Multiple Communications Protocols – The Alpha 420C N12 supports multiple communication protocols. RS232 and RS485 and two RJ11 attachment ports are standard features. Ethernet and POCSAG attachment options are also offered. Numerous cable, network, wireless and modem connectivity options are supported by the Alpha 420C N12 – click here for more information.
• Address Each Display – Each Alpha 420C N12 can be given a unique address, so that messages and data may sent by computer or control devices to different displays on the same cable, wireless channel, modem phone number or TCP/IP address. 255 addresses are available, and the Alpha 420C N12 address may be set or changed easily with the remote control keyboard or using a computer and special software. The Alpha 420C NEMA 12 also has a bank of DIP switches that allow its serial address to be set permanently. This method will survive lengthy power supply interruptions or other conditions that could cause a software-set address to reset.
• Message Verification and Error Checking – Built-in features ensure that messages are received accurately when a computer or control equipment sends messages or data to the Alpha 420C N12 by cable.
• Priority Message – The Alpha 420C N12 has a 125-byte Priority message file that can be activated by special programming. When the Priority message file is activated, all other message files that are currently running stop being displayed. When the Priority message is terminated, the other messages resume displaying.
• Audible Alert – A Tone feature may be invoked to beep the Alpha 420C N12 as needed. Several tone control programming options are built-in.
• Program with both Computer and Keyboard – The Alpha 420C N12 may be programmed by computer and by remote control keyboard without either the computer or the remote control keyboard disrupting the messages programmed by the other device. You may define how much of the storage capacity of the Alpha 420C N12 is reserved for programming by the remote control keyboard. You can also allow or deny remote control keyboard access to message files transmitted to the Alpha 420C N12 by computer.
• Non-Blinking String File Updates – The Alpha 420C N12 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 420C N12 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 420C N12 instantly, without causing the Alpha 420C N12 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 420C N12 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 420C N12.
• Supports Wireless Applications – The Alpha 420C N12 supports POCSAG or pager transmission format. It can be programmed for wireless applications.
• Wireless News and Sports Service – The Alpha 420C N12 can be equipped with a wireless broadcast receiver that will display the latest news headlines, financial market summaries, sports information and scores, in addition to your own messages. The receiver and news service are extra charge options.
• Update Firmware Easily – When new features or firmware improvements for the Alpha 420C N12 are announced by Adaptive Micro Systems, firmware upgrades may be purchased and easily installed. Alpha 420C N12 firmware is provided on a chip conveniently mounted in a chip carrier that literally snaps into a socket inside the Alpha 420C N12 enclosure.
