Page 21: Rev. 100 Mode
Allows compatibility with earlier versions of the 802 and 7802 “version 100” Terminals. These terminals use a different communication protocol that the current 7802 WiFi Terminals and require the version 1 Windows-based Connection Host. Early version Terminals cannot use the web-based Connection Host.
Page 22 The normal operating mode of the 7802 terminal (with rev. 100 mode turned OFF) uses standard TCP connections and HTTP data formatting. Rev. 100 mode is intended ONLY FOR BACKWARD COMPATIBILITY and should NOT be used for developing new applications. Existing applications that use the older terminals can be easily ported to accommodate both old and new 7802 terminals.

Page 34: Chapter 3: Operational Theory
All communication between the parts of the 7802 Terminal system is through standard TCP/IP connections over your ethernet LAN/WAN. The 7802 Terminals require a standard wireless access point. This can be a wireless access point installed on your LAN, a public “hot-spot”, a mobile (cellular) access point, etc.
Page 35: Architecture
Physical The 7802 Terminals always connect to a wireless access point to become part of a LAN. In order for the Terminal to have Internet access, the LAN that it connects to must provide it.
Page 36: Communication Diagrams For Using A Connection Host
Communication Diagrams for Using a Connection Host An Application Server can run on any computer with access to the Internet. Worth Data provides programming tools for creating Windows Application Servers, but you could also create your own that runs on other platforms (Linux, Apple, etc.).
Page 37: Communication Diagram For Using A "Cloud" Application Server
URL that is managed through standard or dynamic DNS, or something similar. The IP address of a particular terminal can also be obtained. Once an 7802 RF Terminal is signed in, it receives messages from the (user created) Application Server via the Connection Host. The terminal responds back to the Application Server program with data that was keyed or scanned by the terminal's user.
Page 38: Logical
Internet connection. Logical The easiest way to think of the logical architecture of the 7802 Terminal system is as a “spoked wheel” or a “star”. Connection Host with Local Application Server Model Think of the center of the star as the Connection Host which serves to link all of the other pieces of your system together.
Page 39: Communication
Communication The 7802 RF Terminal has two modes of communication: • Sign-In Mode – the Terminal associates with an 802.11 access point and connects with your LAN. It then attempts to link with a Connection Host or Web Application Server over the Internet and register with an Application Server with matching username, password, and server ID.
Page 40: How Site Survey Works
3. If the host program does nothing within 2 seconds, the Terminal displays the message: Host Application Not Found Enter: Retry or F1:Exit Lets suppose that a Terminal and a host application program have been processing data by sending prompts and data back and forth as described above.
Page 41 • Metal walls are almost impenetrable by RF. If your access point is located in a metal shed, Terminals will likely not operate very well outside. • The more walls you try to transmit through, the more the signal breaks down. Walls that have metal studs (interior office walls) and concrete walls with steel rebar slightly degrade the signal with each wall you try to go through.
Page 42 If you have difficulty somewhere in the area, as long as that area is in an area of overlapped coverage that a different position of the Access Point covers, you won't have a problem. If you find a spot that none of the planned Access Point locations will cover, you will have to move one of the Access Points closer to the problem spot or plan on adding another closer Access Point.
Page 43 The terminal will do an Access Point Scan and report on the three Access Points with the strongest signals contacted, (or fewer than three is less contacted). You can update the display by pressing ENTER to rescan. The display will have the following format: WorthData1 WPAv1 WorthData2...

• Use the Test Program. Each Terminal come setup to use the default web-based test program. This is hosted by Worth Data. The test program allows you to see how the system functions and whether you can anticipate any system-wide problems. The test program can also be used as a response-time benchmark.
Page 48: Parts Of The System
Keep in mind that it is possible to not need a Connection Host for a fully working system. You can install you own custom “Cloud Server” (see the diagrams above). See the source code for the Worth Data Cloud demo for more information.
Page 49 The Worth Data 7802 WiFi RF Terminal requires an access point to connect to. 2. Local Area Network (LAN) or Cellular Mobile AP (required) Operation of the 7802 Terminal requires at least a local LAN with an access point OR a mobile cellular access point.

Servers, all using the same Connection Host. Worth Data provides a Connection Host already installed on our web site that you can use. While you can use it for production, it is intended for testing and demonstration. It is provided “as-is” and while the user/server ID/password system provides some data security, we cannot guarantee it.
Page 51 Then, copy the necessary files (listed above) to your web site. Typically you will use an FTP client such as Filezilla or whatever is provided by your web hosting service to copy the files out to your web server. When you copy these out to your web server, you should put them in a subfolder to keep them separate from the rest of the content of your web site.
Page 52: Install Local Connection Host And Test Server
Install Local Connection Host and Test Server Your Terminal comes preset to access Worth Data's web-based Cloud Server which provides a very simple testing and setup system for your Terminal. All you have to do is configure your Terminal to connect to your LAN's wireless access point and internet gateway.

Page 54: How To Use Local Test Server
How To Use Local Test Server When you start the Test Server, you will first see a notice about how you must configure your Terminal(s) in order to work with the Local Test Server. Notice that your Terminal must be set to find the Local Test Server on your LAN.
Page 55 If you click on the “Stop Server” button in the Test Server window, the Local Connection Host will shut down and the Test Server will set itself to connect with Worth Data's web-based Connection Host, rather than the Local Connection Host.

Page 66: Terminal Native Command Reference
Terminal Native Command Reference HTTP / Low Level ASCII script sequences Planning Local, PC-based programs can be written in any language that has some way to access TCP communication on your LAN and over the Internet. Web based server applications can be written in any language that can access a database backend and serve HTTP web pages, such as PHP, ASP, Pearl, Python,etc.
Page 67: Terminal Receive Definition
termID serverID termdata You can see that the actual data coming from the terminal is “%0F” which is HTML encoding for ASCII #15, which is a “Sign-In” request. USER, PASSWORD, and SERVERID all come from the Terminal's setup. TERMID is the MAC address of the Terminal and is unique for every Terminal Note that non-printable ASCII characters (as well as “&”, “?”, and “;”) must be sent as %hh, where hh is a two char hex value.
Page 68 This is what the Terminal receives from the Connection Host/web-based App Server in response to a properly configured page request as outlined above. Sample: HTTP/1.1 200 OK Content-Type: text/plain Transfer-Encoding: chunked wd*data:@1,1,1,Enter Data%04 (blank line) Explanation: Basically, the terminal will read the first line and make sure it includes “100 Continue” or “200 OK” (more on this below) and then read lines until it finds a blank line (CR/LF alone).
Page 69 The first byte, RF Terminal ID, is unused and included for backwards compatibility, should you want to port existing RF Terminal applications to the new 7802 system. Leave this set to “0” (zero). The reason that Terminal ID is not used has to do with the way the server works. You can never send anything to a Terminal unless the Terminal requests it, and the Server guarantees a direct one-to-one query- response integrity.
Page 70 There are 16 possible text and background colors available to choose from. They are the same 16 colors used in HTML programming. The @C command has been expanded to set the foreground and background colors for the entire display and within the same command you can also set the font size for the entire display to all be the same or split up the display using different size fonts for each line.
Page 71 lines defined cannot exceed the height of the screen. The total height of the screen is 240 pixels. A small font is 16 pixels tall, a medium font is 24 pixels tall and a large font is 32 pixels tall. If you define 2 lines with small fonts, 2 lines with medium fonts and 2 lines with large fonts you will be using (2x16)+(2x24)+(2x32)=144 pixels out of a maximum of 240 pixels.

Page 110 making your voice prompts user-friendly: 1. Short messages are preferable for prompts; most English prompts can be stated in ½ second. Instead of saying, “Enter the Item Number,” say “Item”. The typical Wi-Fi RF Terminal operator does not want to hear long messages thousands of times. Error messages are typically longer because they are the exception and need to provide more precise instruction to the user.
Page 111: Chapter 9: Troubleshooting
Chapter 9: Troubleshooting General Considerations Changing the Battery For RF Terminals, the most frequent cause of problems is a low battery that has either been ignored or undetected. The real test for the battery is to remove battery from a working unit and place it into a suspect unit.

Page 118: Appendix: Code 39 Specifications
Appendix: Code 39 Specifications Code 39 (or Code 3 of 9) is the de facto standard of non-retail American industry. It is widely used in the automotive industry (AIAG specifications) as well as in government and military applications (LOGMARS specifications). Code 39 is flexible, features a large character set, variable data length and density, and bi- directional readability.
Page 119 Here is an example to illustrate how the check character is calculated for bar code data of 123XYZ: Take the sum of the values assigned to each character: 1 + 2 + 3 + 33 + 34 + 35 = 108 Divide the sum by 43: (thus the name modulus 43) 108/43 = 2 with a Remainder of 22 Find the character corresponding with the remainder.
Page 120 Accumulate Mode Accumulate Mode is an option allowing the RF Terminal to accumulate multiple bar codes in its buffer, then transmit them to the computer as if they had been a single bar code. This is useful for entering quantities and other variable data.
Page 121: Appendix: Code 93 Specifications
Appendix: Code 93 Specifications Code 93 is variable length, continuous, bi-directional, compact code. Code 93 is an alphanumeric bar code which consists of 43 data characters (0-9,A-Z,$/+%.- and Space), 4 control characters, and a unique start/stop character. The entire set of 128 ASCII characters is represented in Code 93 using combinations of control characters and data characters.
