™ Advanced Display Protocol (ADP) 1.0 Introduction The 4U2SEE signs are designed to display text messages, graphics, numeric quantities and other information. This document explains the ASCII (American Standard Code for Information Interchange) communication protocol utilized to communicate with 4U2SEE display boards manufactured by Electro-Matic Products, Inc.
Advanced Display Protocol (ADP) • Version 4.0 ™ 2.0 Settings Within this document are the ASCII commands required to send messages to a 4U2SEE sign via the Ethernet, RS232 or RS485 ports. Alternate devices and software can be used. Caution must be used to make sure the display's port settings and the sending devices settings match, otherwise the devices will not communicate. This document covers 4U2SEE signs with: Firmware Version 8E04 or...
1) If data is issued to the display at intervals quicker than the approximate two (2) seconds, the display may not get updated. 2) To send messages to the 4U2SEE displays, the run sequence or play list may need to be edited or cleared. To accomplish this via the Electro-Matic input devices, please refer to Appendix B: Delete File Playlist or Sequence or to set or delete a current play list or run sequence please refer to section 6.4.11-12.
Folder. 5) Calls (<0x10>) from Simple STRING files to TEXT files are explained in section 6.1.5. 6) Nested STRING Files (reference section 6.1.6) can consolidate (group together) Call(s) to STRING File(s). This command can not be utilized in 4U2SEE Firmware versions prior to 8.E04. 6.1.3 Expanded (“<0x0F”>) TEXT Files (“T”) The Expanded TEXT files are used to store ASCII characters only (reference Appendix C: Valid File Labels and Characters). The ASCII message data and display mode information, along with various other control codes, are stored in Expanded TEXT files on a specified Drive in the TEXT (“T”) Folder.
PLEASE NOTE: All bold text in the above ASCII code format example is supplied to aid each circumstance and all non-bolded format text is explained in Table 2. 6.1.7 Special Functions Electro-Matic Products network supports a range of Special Function commands which give you access to internal registers, diagnostics and other items. The factory defaults listed in section 2.3 can be customized (altered) to accommodate your specific needs, unless otherwise noted. You can customize a solitary value or alter all the default settings at...
PLEASE NOTE: 1) There is no specification for variables and related attributes. 2) Default customization can not be accomplished in 4U2SEE firmware versions previous to 8E04. Mode commands <0x1B> can be embedded into TEXT messages, being used for positioning and incoming/outgoing activities.
4) The ASCII character “y” is reserved. 5) All Simple and Expanded TEXT files are designated for the TEXT (“T”) Folder. 6) The In/Out command codes shown in table 8 are not applicable to 4U2SEE firmware versions prior to 8E04.
Enhanced Version Advanced Display Protocol (ADP) • Version 4.0 ™ 3) There are limitations to the execution of this command in 4U2SEE firmware versions prior to version 8E04. 4) For examples of expanded files display date and time stand command code reference lines 111 128 of Appendix D: Examples of FlexSender Code.
Table 2. 2) This command is not applicable to 4U2SEE firmware versions prior to version 8E04. 3) For examples of expanded files character speed command code reference lines 146-150 of Appendix D: Examples of FlexSender Code.
Table 2. 2) This command is not applicable to 4U2SEE firmware versions prior to version 8E04. 3) For examples of expanded files character hold (stay) command code reference Appendix D: Examples of FlexSender Code.
2) All bold text in the above ASCII code examples are supplied to aid each circumstance and all non bolded text is explained in Table: 2 & 7. 3) This modification of play lists (sequences) can not be accomplished with 4U2SEE prior to firmware version 8E04.

The command clears the messages stored in both the Flash and RAM memory (D and E drives in 4U2SEE). It will also clear the play list from both the Flash and RAM memory (C and E drives in 4U2SEE) regardless of where the play list is saved based on the Default Display Setting.
CAUTION: The following procedure should only be performed by properly trained technicians. This procedure can only be utilized on enhanced display boards, utilizing Sigma 3000 Version 2.14 software, which can be purchased through Electro-matic Products Inc. Warranty will be voided if not performed by trained technicians.

Serial connection is the elected means of communication. To update, install or revise a version of 4U2SEE firmware 8E04 the following steps must be followed: 1) Install Sigma 3000 Version 2.14 (Sigma 3000 Version 1.0.0 [‘Sigma Editor’] is not appropriate) 2) Cycle electrical power (initial users introduce electrical power) and copy down all information displayed on the sign.

9) When ‘CPU Update’ is chosen, a file dialog box will appear. Allowing you to browse to search for the proper file. The file, which can be obtained from Electro-Matic Products Inc., will be named Sign_VER YYYY .cpu. The YYYY represents the firmware version number and the cpu (following a period) is referred to as an file extension.

CAUTION: It is very important not to interrupt power during this procedure, unless specified otherwise. If any power interruptions occur, then the display may be unusable and non-repairable. Damaged 4U2SEE display boards can be shipped to Electro-Matic Products, Inc. in the attempt to salvage at a nominal fee.
3. The third method is utilizing Sigma 3000 software and click on the "Function" tab and then click on the "Delete Play List From Sign". PLEASE NOTE: All devices and software methods can be purchased from Electro-Matic Products, Inc. Methods 2 & 3 (FlexSender and Sigma 3000) must have proper communications between the "host"...
