![OMNI 3600 REFERENCE MANUAL 31CHAPTER 2Using the Terminal KeysBefore proceeding to other tasks, familiarize yourself with the operational features of the Omni 3600 terminal keypad to enter data (see Figure 29). This chapter describes how to use the keypad, including discussions on:•the12-key Telco-style keypad, •the three color-coded keys below the keypad, •the ALPHA key above the keypad, •the four ATM-style function keys (F1, F2, F3, and F4) to the right of the display (Figure 29), and •the four programmable function (PF) keys directly above the keypad. Using these keys you can perform all data-entry tasks described in this manual. Where a specific key is mentioned, it appears within square brackets (for example, the ALPHA key).The function keys allow you to navigate though system mode menus and select specific operations.Figure 29 Front Panel Key ArrangementNOTE The PF and ATM-style keys can also be assigned application-specific functions in addition to those assigned to system mode operations. These functions are not discussed in this manual.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-1.png)
![USING THE TERMINAL KEYSData Entry Modes32 OMNI 3600 REFERENCE MANUALData EntryModesBefore you can use the keys on the front panel to enter ASCII characters, the Omni 3600 must be in a mode that accepts keyed data entry. There are two terminal operating modes, each enables you to press keys to enter data under specific circumstances: •Normal mode: This is the terminal operating mode where an application program is present in SRAM and currently running.•System mode: This is a special, password-controlled terminal operating mode for performing a variety of test and configuration procedures that cannot be performed when an application is running.If you turn on an Omni 3600 terminal that does not have an application stored in SRAM, the system prompt DOWNLOAD NEEDED appears. You can enter system mode by simultaneously pressing F2 and F4, and then entering the password. Once in system mode, you can configure the terminal as required and perform the necessary download.If you turn on an Omni 3600 terminal with an application stored in SRAM, the application executes and the terminal automatically enters normal mode. The application then controls how terminal keys–including the programmable function (PF) keys and the ATM-style keys–process transactions and when you can use specific keys to type characters or respond to prompts.The Keypad The keypad is a 13-key arrangement, consisting of a 12-key Telco-style keypad and the ALPHA key (Figure 29). Using the keypad, you can enter up to 50 ASCII characters, including the letters A–Z, the numerals 0–9, and the following 16 special characters: (*), (,), (‘), (“), (-), (.), (#), (%), (:), (!), (+), (@), (=), (&), (space), and (/).NOTE If you enter system mode while a terminal application is running in normal mode, system mode preempts the application and takes control of the display and keyboard. The preempted application continues to run in the background, but does not accept user input. The only way to exit system mode is to restart the terminal. For this reason, once you enter system mode, you cannot return to the application in the same session.NOTE If an application is in terminal memory, the default system password into system mode may have been changed. If so, you must press a special key combination and then type in the required system password to enter system mode. The behavior of key entries depends on the specific active system mode menu.NOTE The system mode functions described in the next section require that you enter numbers, letters, or symbols using the keypad.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-2.png)
![USING THE TERMINAL KEYSThe KeypadOMNI 3600 REFERENCE MANUAL 33Function KeyDescriptionsThe terminal’s operating mode and context determine the specific action performed when you press one of the following function keys. The following descriptions are provided solely to acquaint you with some general characteristics of these function keys before presenting more detailed system mode procedure descriptions.Cancel KeyPressing the cancel key in normal mode—when the terminal’s application is loaded and running—usually has the same effect as pressing the Esc (escape) key on a PC. That is, it terminates the current function or operation.In system mode, use cancel to perform a variety of functions. The most common use of cancel in system mode is to exit a system mode submenu and return to the main system mode menu. The specific effect of pressing the cancel key depends on the currently active system mode menu.Backspace KeyIn normal mode, the backspace key is commonly used to delete a number, letter, or symbol on the terminal’s display screen. Press backspace one time to delete the last character typed on a line. To delete additional characters, moving from right to left, press backspace once for each character or hold down backspace to delete all characters on a line.In system mode, the specific effect of pressing backspace depends on the currently active system mode menu.ALPHA KeyIn normal mode, the ALPHA key enables you to enter one of the two or more characters or symbols assigned to individual keys on the 12-key Telco-style keypad. Use the ALPHA to enter up to 50 different ASCII characters through the following procedure:1Press the key on the 12-key keypad that shows the letter or symbol you want (for example, use 2 to type 2, A, B, or C). The number (1–9 or 0) or the symbol (* or #) you pressed now displays.2Press ALPHA once to display the first letter. Continuing our example, 2 ALPHA displays the letter A.3Continue pressing ALPHA as many times as required to display the desired character. For example, press 2 to display the number 2; press ALPHA once to display the letter A, twice to display B, or three times to display C. If you press ALPHA one more time, you cycle back to the number 2.NOTE If you firmly press and hold down one of the keys on the 12-key keypad without using ALPHA, the same character repeats until you stop pressing the key. For example, if you press 2 and hold it down, “2222222...” displays](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-3.png)
![USING THE TERMINAL KEYSThe Keypad34 OMNI 3600 REFERENCE MANUALIf two or more characters display on the Omni 3600 screen, pressing ALPHA changes the last character on the line to the next letter, number, or symbol in the key sequence. For example:Tabl e 2 provides additional examples of how to use the ALPHA key to select ASCII characters from the 12-key Telco-style keypad.Tabl e 3 lists all the ASCII characters you can type using the ALPHA key and the Telco keypad.Current display: A5C*2ALPHA A5C*AALPHA A5C*BALPHA A5C*CALPHA A5C*2Table 2 Example ALPHA Key EntriesDesired Character Press Keys2 2A2 ALPHAS7 ALPHA ALPHA ALPHA!# ALPHASpace 0 ALPHA ALPHAComma (,) * ALPHAPlus sign (+) 0 ALPHA ALPHA ALPHATable 3 Using ALPHA and the 12-Key KeypadKey to PressWithout Pressing ALPHAPress ALPHAOne TimePress ALPHATwo TimesPress ALPHA Three Times1 QZ. 1 Q Z .2 ABC 2 A B C3 DEF 3 D E F4 GHI 4 G H I5 JKL 5 J K L6 MNO 6 M N O7 PRS 7 P R S8 TUV 8 T U V9 WXY 9 W X Y0 -SP 0 – [space] +* ,’ ” * , ‘ “#aa.

![USING THE TERMINAL KEYSProgrammable Function (PF) Key DescriptionsOMNI 3600 REFERENCE MANUAL 35Enter KeyIn normal mode, the enter key is generally used the same as the enter key on a PC, that is, to end a procedure, confirm a value or entry, answer “Yes” to a query, or select a displayed option.In system mode, press the enter key to begin a selected procedure, step forwards or backwards in a procedure, and confirm data entries. The specific effect of the enter key depends on the currently active system mode menu.ProgrammableFunction (PF)KeyDescriptionsThe row of four PF keys directly above the keypad (Figure 29) from left-to-right are referred to as PF1, PF2, PF3, and PF4. These keys can be assigned application-specific functions. Because such functions are often unique and can vary greatly between applications, they are not discussed in this manual.The PF keys are also use to toggle through system mode menus. These keys are functioning when arrows appear in the display screen above the associated key, indicating the key’s can be used as follows:•PF1 ↑Move to the previous menu or screen•PF2 ↓Move to the next menu or screen•PF3 ←Scroll left•PF4 →Scroll rightNOTE In system mode, use ALPHA to key in the default system password, to enter a new system password, and for entering alpha characters.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-5.png)

![OMNI 3600 REFERENCE MANUAL 37CHAPTER 3System ModeThis chapter describes a category of terminal functions called system mode operations, including discussions on:•system mode entry,•initiating local and remote operations,•passwords,•file groups, and•system mode menus.System mode is used exclusively by those responsible for configuring, deploying, and managing Omni 3600 terminal installations in the field.When to UseSystem ModeUse system mode functions to perform different subsets of related tasks:•Application programmers: To configure a development terminal, download versions of the Omni 3600 application program you are developing, and test and debug the application until validated and ready to download to other terminals.•Deployers of Omni 3600 terminals to end-user sites: To perform the specific tasks required to deploy a new Omni 3600 terminal in the field, including configuring the terminal, downloading application software, and testing the terminal prior to deployment.•Terminal administrators or site managers: To change passwords, perform routine tests and terminal maintenance, and configure terminals for remote diagnostics and downloads by telephone.To perform the subset of tasks that corresponds to your job, select the appropriate system mode menu(s) and execute the corresponding procedure(s).Local andRemoteOperationsThe system mode operations available on an Omni 3600 terminal can be divided into the following two categories or types:•Local operations: Address a standalone terminal and do not require communication or data transfers between the terminal and another terminal or computer. Perform local system mode operations to configure, test, and display information about the terminal. •Remote operations: Require communication between the terminal and a host computer (or another terminal) over a telephone line or a cable connection. Perform remote system mode operations to download application](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-7.png)
![SYSTEM MODEVerifying Terminal Status38 OMNI 3600 REFERENCE MANUALsoftware to the terminal, upload software from one terminal to another, and perform diagnostics over a telephone line.This chapter contains descriptions on how to perform local system mode operations. For information performing remote operations, such as downloads, refer to Chapter 4.VerifyingTerminalStatusThe Omni 3600 terminal you are working with may or may not have an application program running on it. After you have set up the terminal (Chapter 1) and the terminal is turned on, use the following guidelines to verify terminal status regarding software and current operating mode:•If no application program is loaded into terminal RAM or flash, the message DOWNLOAD NEEDED appears on the display. From this point, press F2 and F4 to enter system mode and perform the required download.•If an application program is loaded into terminal RAM or flash, an application-specific application prompt appears. The application is running and the terminal is in normal mode. If all installation steps are complete, the terminal can process transactions.EnteringSystem ModeTo prevent the unauthorized use of system mode menus, the Omni 3600 terminal firmware requires a system password each time you enter system mode. The default, factory set system password is “Z66831.” Use the following key sequence to enter this password:1 ALPHA ALPHA 6 6 8 3 1 [↵] After entering the correct password, the terminal enters system mode and displays the first system mode main menu, SYS MODE MENU 1. You can now toggle through all seven system mode main menus. File Groups The Omni 3600 operating system implements a file system in volatile, battery-backed RAM and non-volatile flash memory. Files are assigned to one of 15 groups for access control. Groups are similar to directories on a computer in that different applications can be stored in separate file groups, just like different computer applications can be stored in separate directories. Groups are referred to as Group n or GIDn throughout this manual.Each group is protected by a separate password, and each has a separates CONFIG.SYS file. The following rules apply to the Omni 3600 file group system:NOTE It is recommended to enter system mode only on system startup or terminal restart. If you enter system mode while an application is running, system mode suspends the application and takes control of the display and keyboard. The application idles in the background, but no longer accepts user inputs. You cannot return to the application during that session, only after a restart. In addition, an application running in the background may deny access to certain system mode functions.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-8.png)
![SYSTEM MODEPasswordsOMNI 3600 REFERENCE MANUAL 39•The primary application must be downloaded into Group 1.•On terminal power up and after a restart, the terminal defaults to Group 1 as the controlling group. •Group 1 applications have access to files stored in all groups. Other applications can reside in Groups 2 through 14. •Applications in a group other than Group 1 have access only to themselves and files stored in Group 15. •Group 15 is globally accessible, making it an ideal location for files shared by multiple applications, such as shared libraries.•File Groups 1 through 15 are empty until they are filled through a download to the Omni 3600 terminal.For more information on managing file groups, refer to the Verix Programmer’s Manual (VeriFone P/N 19733).PasswordsSystem Password In SYS MODE MENU 3, you can select a procedure to change the default password to a unique and more secure password. Once you set a new system password, be sure to secure a copy of the new password.A valid system password may consist of one to ten alphanumeric characters. You can change the system password at any time, provided you know what the current password is.When you key in the system password to enter system mode, an asterisk (*) appears on the display for each character you type. These asterisks prevent your password from being seen by an unauthorized person. You can use the ALPHA key to change the characters or symbols you enter; this does not cause additional asterisks to appear.File GroupPasswordsFrom manufacture, each file group uses the default password “Z66831,” entered as: CAUTION If you change a password and then forget it, there is no password recovery method. Without the password, you are unable to access system mode operations and may be prevented from requesting a download, performing remote diagnostics, or changing any of the information already stored in memory. The terminal can, however, continue to process transactions in normal mode. If you forget or lose the system password to your terminal, please contact your local VeriFone representative for assistance.NOTE Some application program downloads automatically reset the system password. If your system password no longer works, check if a download has changed your password.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-9.png)

![SYSTEM MODESystem Mode Menus52 OMNI 3600 REFERENCE MANUALEdit Keyed Files A keyed file is a collection of individual records, which contain ASCII data and are identified by unique search keys. You can edit the ASCII data directly from the terminal keypad using the terminal’s built-in keyed file editor. Each record has two parts: a key name and a key value. The search key is a variable-length string, or key name, that identifies the record. The information assigned to the search key is contained in a separate variable-length string, or key value.For example, in CONFIG.SYS, the ZonTalk key for the application serial ID number is *ZT. The value for the key is the actual application ID number. By entering *ZT using the editor, the terminal can quickly locate the application serial ID number. You can also use [↵] to scroll through the search keys instead of entering the characters *ZT through the keypad.CONFIG.SYS: Protected and Non-protected RecordsThe concept of protected and non-protected records applies only to the CONFIG.SYS files in your terminal. Protected records are those with search keys beginning with an asterisk (*) or a pound symbol (#). Prior to a download, the recommended procedure is to clear RAM files. Protected records in the File Group 1 CONFIG.SYS file are retained in a full application download and when RAM is cleared. Non-protected records are all other CONFIG.SYS files, and records of other files. These records are deleted when RAM is cleared.Editing CONFIG.SYS with an External EditorYou can create and edit the CONFIG.SYS files of Omni 3600 applications through an IBM PC-compatible computer when you download files to the terminal. For more information on editing an application’s CONFIG.SYS file, refer to the ZonTalk 2000® Reference Manual, the Verix Programmer’s Manual, or contact your local VeriFone representative.For more information about using VeriCentre Download Management Module in client-server installations, please contact your local VeriFone representative.System ModeMenu 4In this menu you can view the error log and perform application debugging operations.NOTE When entering any password, an asterisk (*) appears on the display for each character you type. These asterisks prevent your password from being seen by an unauthorized person. Pressing the ALPHA key changes the characters or symbols you enter, but ALPHA does not cause additional asterisks to appear. Secure a copy of every password to ensure it is not forgotten or lost.NOTE For a complete list of the ASCII characters supported by the Omni 3600, as well as their decimal and hexadecimal equivalents, please refer to Appendix B.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-22.png)

The types of files and data can be grouped into the following functional categories:•Operating system files: A set of related programs and data files provided by VeriFone to control the terminal’s basic processes and functions. Files that belong to the OS are stored in a reserved area of the terminal memory.A complete OS is downloaded to each Omni 3600 terminal during the manufacture. If necessary, download newer versions during application development, when preparing for deployment, or to terminals in the field.•Applications and related files: An application is a computer program consisting of one or more executables, including compiled and linked object files (*.out), and one or more function libraries (*.lib). Most applications also include font files (*.vft, *.fon), data files (*.dat), and other related file types.Omni 3600 applications can be developed by VeriFone, customers, or third parties on customer request. One or more applications must be downloaded to the Omni 3600 terminal before it can be deployed at a customer site and used to process transactions.•Files related to file authentication: The logical component of the VeriShield security architecture in the Omni 3600 terminal is file authentication. For an executable to run on an Omni 3600 terminal, it must be authenticated by the VeriShield file authentication module.Two special types of files are required for the file authentication process: digital certificates (*.crt) and signature files (*.p7s). These file types must be downloaded to the terminal together with the application files to authenticate.•Terminal configuration settings: Files or records that contain various types of data can also be downloaded to an Omni 3600 terminal, including NOTE No special software tool or utility is required to perform back-to-back application downloads. Only a serial cable connected between two terminals is required.

OS and application downloads can be combined. The file authentication module is not invoked until the terminal is restarted following the download procedure.Omni 3600DownloadDifferencesTo help you plan download tasks and explain how the download procedures for Omni 3600 terminals may differ from those you may be accustomed to using for other POS terminals, some information on the following related topics is included in this chapter:•Support for multiple applications•Use of RAM and flash memory•Redirection of files during application downloads•File authentication requirementsSupport forMultipleApplicationsThe Omni 3600 terminal architecture supports multiple applications. This means that more than one application can reside in terminal memory, and that more than one application can run (execute) on the terminal.The application memory of the Omni 3600 terminal uses a system of file groups to store and manage multiple applications, as well as operating system files, in such a way that the data integrity of each application is ensured and that applications do not interfere with each another (see File Groups, page 38).How the File System Supports Multiple ApplicationsThe application memory partition of the Omni 3600 terminal is divided into 15 logically-defined sub-partitions called file groups or GIDs These groups are called Group 1, Group 2, and so on through GID15. Another partition of the terminal memory area, called Group 0, is reserved for the operating system and is logically separated from the application memory area. So, including Group 0, there is a total of 16 file groups.An application must be downloaded into a specific file group, along with any related files. You select the target file group for the download using system mode menu options and by entering a file group password.Usually, one application is stored in one file group. An application can, however, consist of more than one executable program file, and any number of executables (*.out or *.lib) can be stored in a given group. In most implementations, there is a main application, one or more related programs or secondary applications, and one or more libraries.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-32.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 63The main application must always be stored in the Group 1 sub-partition. Related programs or secondary applications can be stored in GIDs 2–14. GID15 is available to all other groups.The Main Application is Always Stored in GID1The main application stored in GID1 is the controlling application for the terminal. Any function call that invokes a related program or a secondary application stored in GIDs 2–14 must be initiated by the GID1 application.An application stored in a file group other than GID1 is limited in that it can only access executables and files stored in its own file group and in GID15.Physical and Logical Access to File GroupsThe Omni 3600 operating system controls physical access to GIDs 1–15 using password-protected system mode functions. To download data into a specific file group, you must first enter system mode and choose the target group by making the appropriate menu selections. Then, you must enter the correct password for that file group.Each file group has its own CONFIG.SYS file. The CONFIG.SYS settings of the target group you select are always used as the system parameters for the download operation you are performing.The system of file groups also imposes some logical restrictions on which files can download into which file groups:•If GID1 is selected as the target group in system mode, you can download files into GID1 and redirect files into any of the other file groups, as required, in the same download operation.•If another file group is selected as the target file group, you can download files only into that group and redirect files only to GID15. For example, if you select GID5 as the target group for the download, files can only download into GID5 and be redirected to GID15.Use of RAM andFlash MemoryThe Omni 3600 application memory partition has two separate file systems:•RAM (battery-backed volatile memory, also called SRAM), drive name I:•Flash (non-volatile memory), drive name F:The fact that there are two different file systems has the following important implications for data transfer procedures:•Depending on the requirements of a specific application, some files must download into RAM and others into flash.•There are also rules that restrict which types of files you can download and store in which file system (RAM or flash).](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-33.png)

Other file types, such as operating system files, digital certificates, and signature files, must download into RAM.In a typical download procedure, all files are loaded into the RAM file system of the target group selected in system mode. Specific files included in the download package must be redirected, as necessary, to the flash file system of the target group or to the RAM or flash file system of another file group.To redirect files during a download procedure, see the following sections.Defragment Flash For Application DownloadsBefore you perform an application download, you may need to defragment terminal flash memory. For information on performing this system mode operation, see Table 7, page 45.To ensure the best result when performing back-to-back downloads, you may need to defragment the flash memory on the receiving terminals. A system mode procedure is also available for clearing the RAM or flash memory, either entirely or for a specific file group, to prepare an Omni 3600 for a clean download.Redirection ofFiles DuringApplicationDownloadsYou can download application files into RAM or flash memory. By default, files that you download to a specific file group are stored in the RAM of that group. To store a file in flash of that file group, you must provide instructions to redirect the file to flash as part of the procedure.There are two methods you can use to redirect files during an application download, depending on the download tool you are using:•If you are using Download Manager or ZonTalk 2000, you must manually create and include special zero-length files called SETDRIVE.x and SETGROUP.n on the download computer, and add these files to the batch download list to direct files to a specific file system (drive) or file group.•If you are using DDL.EXE to perform direct downloads, you can use a special command-line option that automatically redirects files to the drive and file group you specify.Both of these methods are further described in the following sections.NOTE The flash defragment operation is not necessary for an Omni 3600 terminal just out of the box. In this case, the terminal flash file system is still in its factory-new condition.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-34.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 65Manually Redirecting Files to Flash MemoryTo manually redirect files to flash memory for Download Manager or ZonTalk 2000 application downloads, you must create one or more files on the download computer with the special file name, SETDRIVE.x, where, x is the name of the drive (memory area) to download files to:•Drive name I: is RAM: This is the system mode default for downloads.•Drive name F: is flash.To create a zero-length SETDRIVE file on the download computer, use the DOS command, REM, as in the following example:REM >SETDRIVE.FTo redirect a file from RAM of the target group to flash of the same file group, insert the zero-length SETDRIVE.F file into the batch of application files to download. All files that follow the SETDRIVE.F file in the download list automatically load into flash memory (F:) of the target group.If you do not insert a SETDRIVE.F special file in the download list, all files download by default into the RAM (drive I:) of the target file group. You can also insert a zero-length file with the name SETDRIVE.I into the download list at any point to indicate that the following files download into RAM.For example, the following batch download list loads the executable code file FOO.OUT into the RAM of the selected file group (default Group 1). Because the signature file, FOO.P7S is included, FOO.OUT is also authenticated when the terminal restarts after the download.The *GO variable in this example indicates that the FOO.OUT application executes on restart, after successful authentication. The two data files that follow the zero-length SETDRIVE.F file, FOO.DAT and FOO.VFT, are redirected into flash of GID1.

Together, the zero-length SETDRIVE.x and SETGROUP.n files allow you flexibility to store files as required in RAM or flash file systems and in specific file groups in a single batch download operation.Redirecting Files to Other File GroupsGID1 is the default system mode setting for performing downloads. Using the system mode menu options, you can select another file group (GID 2–15) as the target group for the application download. If you select another group, files download directly into the RAM of that file group.To redirect files from the selected target file group to another file group as part of the download operation, insert a zero-length SETGROUP.n file in the batch download list (the same as SETDRIVE.x). The syntax of this convention is SETGROUP.n, where n= 1–15, for GIDs 1–15.To create a zero-length SETGROUP file on the download computer, use the DOS command REM as in the following example:REM >SETGROUP.2If you do not insert SETGROUP.n special files into the download list, all files download into the target group selected in system mode. If no number is added to the SETGROUP filename, SETGROUP.1 (GID1) is assumed.Restrictions on File RedirectionThe Omni 3600 file system restricts how you can redirect files to other file groups. Here are the important points to remember:•The main application must always be downloaded into GID1.•Because of the way file groups are managed in the Omni 3600 file system, only two schemes are available for redirecting files during a batch application download:•If, using system mode menu options, you select Group 1 (default) as the target group for the download, files can be redirected to any other file group, including GID15.•If, using system mode menu options, you select a file group other than Group 1 (GIDs 2–14) as the target group for the download, files can be redirected only into the selected file group or into GID15.NOTE You can only use zero-length SETDRIVE.x files for batch application downloads, either direct or telephone, and only using the Download Manager or ZonTalk 2000 download tools (and not DDL.EXE). You cannot use this special file convention for operating system downloads or for back-to-back application downloads.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-36.png)

The download list loads FOO.OUT into Group 1 RAM, GOO.OUT into GID2, and the shared library, COMN.LIB, into GID15. When the terminal restarts after the download, the file authentication module is invoked for all three files, based on the certificate data that authorizes them to be stored in their respective file groups.If FOO.OUT is authenticated, the GID1 application, FOO.OUT, executes, as specified by the *GO variable, when the terminal restarts following successful file authentication.

The syntax is as follows:SETDRIVE.<drive letter>where, drive letter is I: (RAM, default) or F: (flash), and/orSETGROUP.<group number>where, group number is 1–15.For example, the following command-line entry:DDL SETDRIVE.F cardco.lib SETDRIVE.I SETGROUP.15 card.datdownloads the executable file cardco.lib into the flash of the selected target group and the data file card.dat into Group 15 RAM. (Because drive or group settings apply to all files that follow in the list, it is necessary to use SETDRIVE.x to reset the drive from F: back to I:.)If you are using this DDL.EXE method, zero-length SETDRIVE.x and SETGROUP.n files do not need to exist as files on the download computer.NOTE You can only use zero-length SETGROUP.x files for batch application downloads, either direct or telephone, and only using the Download Manager or ZonTalk 2000 download tools (not DDL.EXE).

![PERFORMING DOWNLOADSOmni 3600 Download Differences68 OMNI 3600 REFERENCE MANUALFile Redirection in Operating System DownloadsWhen performing an operating system download, you must download the OS files into Group 1 RAM and not into flash memory or into another file group.OS files download into Group 1 RAM because is not possible to download these files directly into Group 0. OS files are redirected to Group 0 depending on if you perform a full or partial download (see Table 13, page 60):•For full OS downloads, the redirection of OS files into Group 0 is performed automatically, after the terminal restart, as part of the download procedure.•For partial OS downloads, OS files are redirected from the RAM of Group 1 into Group 0 on manual terminal restart by selecting the appropriate system mode menu option.A downloaded OS is processed and authenticated while stored in Group 1 RAM. As the files are authenticated under the authority of the certificates and signature files included in the OS download package, they move automatically into Group 0. This process, which usually takes a few minutes, is completely transparent during the download procedure.File Redirection in Back-to-Back Application DownloadsIn a back-to-back application download, all application files stored on the sending terminal — in both file systems and in all file groups — transfer to the receiving terminal in a single operation.For this type of download, you must select Group 1 as the target group on the sending and receiving terminal. When you initiate the download on the receiving terminal, all application files, as well as all special files required for file authentication and terminal configuration settings on the sending terminal, download to the receiving terminal.In this type of data transfer operation, some file redirection does occur automatically as a result of the file authentication procedure that occurs on the receiving terminal. This redirection process is transparent during the download.Briefly, all files initially download into RAM, and are then redirected based on the directory and subdirectory names of the sending terminal’s file system. Signature files must always be authenticated in RAM. If the target file the signature file authenticates is stored in flash, the signature file is moved to flash only after the target file is successfully authenticated.To successfully perform a back-to-back download, all signature files that are required to authenticate application executables must reside in the memory of the sending terminal. If the *FA variable is present in the Group 1 CONFIG.SYS file of the sending terminal, it must be set to 1 to retain all previously downloaded signature files.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-38.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 69If a signature file is missing on the sending terminal, the target application file that it authenticates is not authenticated on the receiving terminal and, if the target file is an executable, it is not allowed to run on the receiving terminal.File AuthenticationRequirementsChapter 5 provided a general introduction to the file authentication process. Now we become more task-oriented and see how the file authentication process affects how to perform the various download procedures.Required Certificates and Signature FilesHere are some important points to remember about how certificates and signature files relate to application download procedures:•Before an executable file can be downloaded to and be allowed to run on an Omni 3600 terminal, the file must be digitally signed on the download computer using the file signing tool, FILESIGN.EXE. The result of this procedure is a signature file recognized by its *.p7s file name extension.•A signature file must be downloaded together with each executable that makes up an application. An executable can be a compiled and linked object file (*.out) or a shared function library (*.lib). In most cases, an application consists of multiple executables and requires a number of corresponding signature files.•In a typical batch application download, all files, including executables, signature files, and any required certificates, download together in the same operation. •After the download is complete and the terminal restarts, the file authentication module is invoked if a new signature file (or certificate) is detected. If the application (executable) is authenticated, it is allowed to run on the terminal. Otherwise, it does not execute.•If one executable file is required by an application that consists of multiple executables fails to authenticate, the main application may crash when it attempts to access the non-authenticated executable.•Application files other than executables (for example, font and data files) may also require logical security under file authentication. In these cases, each protected non-executable file also requires a corresponding signature file.•Digital certificates (*.crt) and signature files (*.p7s) required to authenticate both application files and operating system files must always be downloaded into RAM of the target file group.•Certificate files are deleted from application memory after they are authenticated. If a certificate is not authenticated, it is retained in the terminal memory.•If the *FA variable in the CONFIG.SYS file of the target group is set to 1, signature files are redirected to the same location where the application file it](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-39.png)
![PERFORMING DOWNLOADSOmni 3600 Download Differences70 OMNI 3600 REFERENCE MANUALauthenticates is stored. If *FA is 0, signature files are deleted from RAM when the file authentication process is complete.The File Authentication Process During an Application DownloadIn the following example of a typical file authentication process, it is assumed that we:•are downloading an application to prepare an Omni 3600 deployment terminal for deployment. That is, a sponsor certificate and a signer certificate download in batch mode to GID1 RAM of the receiving terminal, together with the application to authenticate.•generated a signature file for each executable that comprises the application on the download computer using FILESIGN.EXE, with the signer certificate, signer private key, and signer password as required inputs. These signature files are also downloaded to the receiving terminal.In a typical batch application download, file authentication proceeds as follows:1All certificate files (*.crt), signature files (*.p7s), and application files (*.out, *.lib, *.fon, *.vft, *.dat, and so on) download to the Omni 3600 deployment terminal in batch mode.2When the terminal restarts after the download, the file authentication module searches the RAM-based file system for the following two file types:•Authenticated certificate files (*.crt) to add to the permanent certificate tree•Signature files (*.p7s) that authenticate corresponding target application filesCertificate files and signature files can download into the RAM of any file group. For this reason, the file authentication module searches through the entire file system (all file groups) for new files with these filename extensions each time the terminal restarts.3The file authentication module builds a list of all newly detected certificates and signature files. If no new certificates or signature files are located, the module just returns. If one or more new files of this kind are detected, the file authentication module starts processing them based on the list.4Certificates are always processed first (before signature files). The processing routine is called one time for each certificate in the list. If a certificate is authentic, it is noted, and the next certificate processed. This process continues in random order until all certificates are authenticated.When a certificate file in the processing list is authenticated, the “Authenticated” message displays below the corresponding filename. If it fails to be authenticated, the “Failed” message displays for five seconds and the terminal beeps three times (see Figure 30). The routine then resumes processing and continues until all certificates are successfully processed.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-40.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 71The processing routine gives you both visible and audible indications if a specific certificate successfully authenticates. The file authentication module does not halt the process if a certificate fails to authenticate, but continues to the next step: authenticating signature files.If one or more certificates fail to authenticate, the ensuing file authentication process based on signature files probably also fails, with the result that an application is not authenticated and is not allowed to execute on the terminal.When a certificate file is authenticated, the data it contains is added to the certificate tree and the certificate file is deleted from the RAM. When all required certificates are authenticated and stored in the certificate tree, the file authentication process for signature files can proceed.Figure 30 Display Prompts During the File Authentication Process5Signature files are processed next (after certificate files). The file authentication module calls the signature checking routine one time for each new signature file it detects. Each *.p7s file is checked as it is detected; a list is not built and multiple processing passes are not required. •If a signature file is authenticated, the “AUTHENTIC” message displays and the target file’s ATTR_NOT_AUTH bit is set to 1.•If the authentication process fails, the “FAILED” message displays for five seconds and the terminal beeps three times (see Figure 30). The routine then continues processing the next signature file until all newly detected signature files are checked.•If a signature file fails to authenticate and its target file is an executable code file, such as *.out or *.lib, the executable is not allowed to run on the terminal on terminal restart.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-41.png)
![PERFORMING DOWNLOADSOmni 3600 Download Differences72 OMNI 3600 REFERENCE MANUALFor data files, font files, and any other files that require authentication to meet the application’s design specification, the application must ensure that these files successfully authenticate.While a signature file is being processed, it remains stored in the RAM file system of the target file group. The target application file may be redirected immediately on download to RAM or flash. When the signature file successfully authenticates its target file, it is automatically moved to same the file system and file group as the target file it authenticates (that is, if *FA = 1).The processing routine gives you visible and audible indications of if a specific signature file successfully authenticates. The file authentication module does not halt the process if a signature file fails to authenticate, but continues to the next step: storing the downloaded files in their final locations in the terminal file system.6Certificate files and signature files are retained in the RAM file system until the file authentication process is complete. These special files are then either deleted or automatically redirected to another file system or file group, as previously described.When an application file is authenticated, the operating system sets the file’s read-only attribute to protect it from being modified while stored in terminal memory. This is also true for a signature file retained in terminal memory. When a signature file is assigned the read-only attribute, it is no longer detected as a new signature file by the file authentication module on terminal restart.7When all certificates and signature files are processed and special files deleted or redirected as required, the terminal restarts and the *GO application executes.File Group PermissionsNow, consider how file authentication controls who (which business entity) can store application files in which file groups in the Omni 3600 file system.By inserting zero-length SETDRIVE.x and SETGROUP.n files into a download list, you can specify which drive (x = I: RAM or F: flash) and which group (n = 1–15) to store an application file. In addition to this file redirection protocol, the file authentication module controls which files are allowed, under the authority of the signer certificate used to sign them, to be stored in which file groups in the Omni 3600 file system.For example, if the terminal owner specifies that a loyalty application in be stored GID2, the information is encoded in the sponsor and signer certificates issued by the VeriFone CA for that terminal.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-42.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 73Chapter 5 discussed how signer certificates are required inputs to FILESIGN.EXE when preparing a deployment terminal. Each signature file generated under that signer certificate contains a logical link that allows the application to authenticate and run on the terminal only if the signature files and corresponding target files are downloaded into the target GID.Although you can store files in any file group simply by selecting the target group in system mode, the files you download are not authenticated for the target group you selected unless they are properly signed under the authority of the sponsor and signer certificates issued for that terminal.Download an Operating System Update Provided by VeriFoneBecause the operating system software for the Omni 3600 is developed and controlled by VeriFone for its customers, VeriFone provides the necessary certificates and signature files to ensure the authenticity and integrity of the operating system update as part of the download package. The file authentication procedure for OS downloads is much the same as application downloads, with the following exceptions:•VeriFone provides all files required for the OS download, including•The operating system files (such as Q.out, 1.out, and 2.out),•An encrypted list of the new files, called VFI.PED, and•A signature file generated by the VeriFone CA under the authority of a higher-level OS partition sponsor certificate, called VFI.P7S. The file authentication logic on the receiving terminal uses this signature file to confirm the origin and authenticity of the encrypted list of files, VFI.PED.•You must download the entire OS package into Group 1 RAM. If you select a target group other than Group 1, the operation fails.•Before you initiate an OS download, either full or partial, ensure enough memory space is available in Group 1 RAM to temporarily store the OS files and that any application files can also be stored in Group 1.•If you have selected a full OS download in system mode, the terminal restarts automatically and the new OS is processed and replaces the existing OS. In this download operation, all application files stored in Group 1 are automatically erased.•If you select a partial OS download, the operating system returns control to system mode after the download completes. To process the new OS, you must manually restart the terminal by selecting the appropriate system mode NOTE Operating system files can only be transferred to an Omni 3600 terminal using a PC-to-terminal download procedure, either direct or by telephone. OS files cannot be downloaded to an Omni 3600 terminal in a back-to-back operation.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-43.png)

When the new OS is processed (this usually takes a few minutes), the terminal restarts automatically and the OS download procedure is complete.File Authentication for Back-to-Back Application DownloadsWhen performing a back-to-back application download between two docked Omni 3600 terminals, the file authentication process on the receiving terminal is similar to an application download from a host computer to a standalone Omni 3600 terminal. There are, however, some important differences to take into account:•Only a full application download is supported for back-to-back data transfers. You cannot perform partial back-to-back application downloads.•Before you can initiate the back-to-back download, you must enter system mode in both terminals, select Group 1 as the target group for both terminals, and enter all required passwords.•All signature files required to authenticate the download application(s) must reside in memory of the sending terminal. They must not be deleted through the *FA variable being cleared to 0 on previous downloads.•Any sponsor and signer certificates downloaded to and authenticated on the sending terminal are stored in the certificate tree of that terminal. When you perform a back-to-back download, certificate files are reconstructed from the data present in the sending unit’s certificate tree.•All certificates transfer to Group 1 RAM on the receiving terminal, except for the highest-level platform root certificate, which can never be transferred to another terminal.•When certificates are detected by the file authentication module of the receiving terminal, they are processed exactly the same as in a direct download: All certificates are checked one by one and, on authentication, are added to the certificate tree of the receiving terminal. Then, all signature files are checked.CAUTION If the power supply to the receiving terminal is accidentally cycled during an operating system download procedure, the terminal may permanently lock up. In that case, return the terminal to VeriFone for service.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-44.png)
![PERFORMING DOWNLOADSOmni 3600 Download DifferencesOMNI 3600 REFERENCE MANUAL 75•Downloaded certificates (receiving terminal) must synchronize with the certificate data present in the certificate tree. Synchronized means the following:•The certificate tree of the receiving terminal can be no more than one revision out-of-sync with the certificate tree on the sending terminal or the files on the receiving terminal do not successfully authenticate. In this case, the term revision refers to any generic change to the current sponsor and signer certificates stored in the certificate tree of a deployment terminal.•When the back-to-back download completes and all certificates and signature files authenticate, the receiving terminal restarts. If the name of the *GO application is specified in the Group 1 CONFIG.SYS file of the receiving terminal, the application executes and the application prompt or logo displays on the terminal. Timing Considerations Due to the Authentication ProcessThe file authentication process takes some time. The total amount of time required depends on a number of factors, including:•the number and size of application files, •the number of certificates and signature files, and •if you are using the file compression feature of Download Manager to perform the download. Here are a few additional considerations that may affect the total elapsed time required to complete the download operation:•Because additional processing steps are required, an operating system download takes longer to complete than an application download (several minutes as opposed to a few seconds).•The download order of a batch of certificate files may affect total processing time. Digital certificates are validated in a looping process where the validation process cycles as many times as necessary to establish the proper relationship and position of a given certificate in the certificate tree that exists in the terminal. To optimize the authentication process, you can download certificates in a higher-level-certificates-first order. This way, they process faster than a random order download.Optimize Available Memory Space for Successful DownloadsOne certificate file or signature file requires approximately 400 bytes of memory space. The application designer must account for the extra memory required to download and store these special files.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-45.png)
![PERFORMING DOWNLOADSEffect of Downloads on Existing Files and Data76 OMNI 3600 REFERENCE MANUALWhen planning your download procedure, carefully consider the total amount of memory space required to store certificates and signature files and the application files. In some cases, a considerable number of 400-byte signature files reside in terminal memory at any given time. Here are some general guidelines to follow:•Know the size of available memory (RAM and flash) of the receiving terminal; in back-to-back downloads, memory on both the sending and receiving terminal.•Know in advance how application files are redirected to RAM or flash and to file groups other than the target group.•Defragment flash memory before performing a download to optimize the available space in the flash file system.•Before you perform a download, use system mode menu selections to clear the entire RAM and/or flash or the RAM or flash of a specific file group, as necessary to ensure proper use of available memory in the target group.Support for FileCompressionFor information regarding file compression, refer to refer to the Verix Operating System Programmer’s Manual (VeriFone part number 19733).Effect ofDownloads onExisting Filesand DataWhen you download application files and data to an Omni 3600 terminal, an important consideration is the effect of download procedure on existing application files, files used in the file authentication process, and terminal configuration settings stored in CONFIG.SYS files in the receiving terminal. Here are some important points to remember:•If a file already exists in the target file group, the existing file is replaced with the new file of the same name. (Files in separate file groups can have identical names.)•Always download executable files (and any other files to logically protect under VeriShield file authentication) together with the certificates and signature files required to authenticate them.•In full or partial application downloads, all CONFIG.SYS records on the receiving terminal, both protected and non-protected (beginning with * or #), are retained. New CONFIG.SYS variables included in the download package, including the *GO variable, selectively replace existing variables with the same key name in the CONFIG.SYS file of the target group.•All current passwords are retained on the receiving terminal during an application or operating system download (direct, by telephone, and back-to-back). This includes the system mode password and file group passwords. If required, you can replace existing file group passwords with new values as part of the data transfer operation.NOTE Always modify the system mode password in a separate, securely-controlled operation.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-46.png)

![OMNI 3600 REFERENCE MANUAL 97CHAPTER 5File AuthenticationThis chapter:•introduces the file authentication module of the VeriShield security architecture, and the organizational infrastructure that supports this feature.•explains how the file authentication process may affect the tasks normally performed by application programmers, terminal deployers, site administrators, or by entities authorized to download files to an Omni 3600 terminal.•describes how to use the file signing utility, FILESIGN.EXE, to generate the signature files that are required to perform downloads and authenticate files on the Omni 3600 terminal.In Chapter 4, the topic of file authentication is also discussed in the context of specific file download procedures.Introduction toFileAuthenticationThe Omni 3600 terminal has a new type of security architecture, developed by VeriFone. This architecture, called VeriShield, has both physical and logical components. The logical security component of the VeriShield architecture, which is part of the terminal’s operating system software, is called the file authentication module, or simply, file authentication.File authentication is a secured process for authenticating files using digital signatures, cryptographic keys, and digital certificates. This process makes it possible for the sponsor of an Omni 3600 terminal to logically secure access to the terminal by controlling who is authorized to download application files to that terminal. It proves and verifies the•file’s origin•sender’s identity•integrity of the file’s informationThe VeriFoneCertificateAuthorityTo manage the tools and processes related to the file authentication module of the VeriShield security architecture, VeriFone has established a centralized VeriFone Certificate Authority, or VeriFone CA. This agency is responsible for managing keys and certificates. The VeriFone CA uses an integrated set of software tools to generate and distribute digital certificates and private cryptographic keys to customers who purchase Omni 3600 terminals.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-67.png)
![FILE AUTHENTICATIONIntroduction to File Authentication98 OMNI 3600 REFERENCE MANUALSpecial Files Usedin the FileAuthenticationProcessThe following specially formatted files support the file authentication process:•A digital certificate is a digital, public document used to verify the signature of a file.•A digital signature is a piece of information based on both the file and the signer’s private cryptographic key. The file sender digitally signs the file using a private key. The file receiver uses a digital certificate to verify the sender’s digital signature.•Signer private keys (*.key files) are securely conveyed to clients on smart cards. The secret passwords required by clients to generate signature files, using signer private keys, are sent as PINs over a separate channel such as registered mail or encrypted e-mail.Some files, such as private key files, are encrypted and password-protected for data security. Others, such as digital certificates and signature files, do not need to be kept secure to safeguard the overall security of VeriShield.Within the FILESIGN.EXE tool, you can recognize the special file types that support the file authentication process by their filename extensions:All digital certificates are generated and managed by the VeriFone CA, and are distributed on request to Omni 3600 clients — either internally within VeriFone or externally to sponsors.All certificates that are issued by the VeriFone CA for the Omni 3600 platform, and for any VeriFone platform with the VeriShield security architecture, are hierarchically related. That is, a lower-level certificate can only be authenticated under the authority of a higher-level certificate. The security of the highest-level certificate, called the platform root certificate, is tightly controlled by VeriFone.The required cryptographically-related private keys that support the file authentication process are also generated and distributed by the VeriFone CA.Certificates Contain Keys That Authenticate Signature Files•Sponsor certificate: Certifies a client’s sponsorship of the terminal. It does not, however, convey the right to sign and authenticate files. To add flexibility to the business relationships that are logically secured under the file authentication process, a second type of certificate is usually required to sign files.A sponsor certificate is authenticated under a higher-level system certificate, called the application partition certificate.File Type ExtensionSignature *.p7sPrivate key *.keyDigital certificate *.crt](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-68.png)
![FILE AUTHENTICATIONIntroduction to File AuthenticationOMNI 3600 REFERENCE MANUAL 99•Signer certificate: Certifies the right to sign and authenticate files for terminals belonging to the sponsor.A signer certificate is authenticated under the authority of a higher-level client certificate (the sponsor certificate).The required sponsor and signer certificates must either have been previously downloaded and authenticated on the terminal, or they must be downloaded together with the new signature files and target files for them to authenticate.Signer Private Keys Are Issued to Secure the File Signing ProcessSigner private keys are loaded onto a smart card. This smart card is securely delivered to the business entity that the terminal sponsor has authorized to sign, download, and authenticate applications to run on the sponsor’s terminal. The VeriFone CA can also issue additional sets of sponsor and signer certificates, and signer private keys to support multiple sponsors and multiple signers for a specific platform.To establish the logical security of applications to download to an Omni 3600 terminal, the designated signer uses the signer private key issued them by the VeriFone CA as a required input to the file signing tool, FILESIGN.EXE. Every signature file contains information about the signer private key used to sign it.When a signature file generated using a signer private key downloads to the Omni 3600 terminal, if it is successfully authenticated depends on whether the signer private key used to sign the target file matches the signer certificate stored in the terminal’s certificate tree.How FileAuthenticationWorksFile authentication consists of three basic processes:1Development: The file signing software tool FILESIGN.EXE creates a signature file for each application file to authenticate.2Pre-deployment: An optimal certificate structure is determined, and the necessary certificates and keys created.3Deployment: The development and pre-deployment processes, once complete, are used in combination to prepare a terminal for deployment.Development ProcessIn this process:1The application developer creates an application file.2The developer assigns a name to the application file.NOTEOnly one sponsor certificate is permitted per terminal.](https://usermanual.wiki/Verifone/OMNI3600D.User-Manual-Part-III/User-Guide-370919-Page-69.png)
