2-3 More than one Setup P arameter can be cha nged before you scan END SETUP. For example, if you scanned START SETUP , then “ Beep Tone ”, then 3 , then “ Speaker Operation ”, then 1 , then END SETU P, this would change the beep tone t o “ high ”, and t urn the speaker " of f ".
2-4 The groups in the keypad Setup M enu contain the following set up parameters: Setup Group Parameter Setup Group Parameter RF Setup Device IP Date/Time Set Time 0 Server IP 3 Set Date Subnet Mask D.
2-5 RF Terminal Setup Parameters Default settings are shown in bold type in this manual and are ma rked by a * on the bar co de Setup Menu. The RF Terminal will typically require no setup chan ges except, Device Address (if more than one t erminal) and en abling bar codes to be read ot her than UPC or C ode 39.
2-6 SSID Default SSID None User Defined XXXXXXXXXXX • If wish to restrict terminal device to a specific network name, ente r the name here (up to 32 chs). The default setting is NON E. You will need to change it in orde r to sign on to your network.
2-7 • If you set this feature to 1 (YES), in order for th e RF Terminal to transmit the following valu es, the corresponding Co ntrol Key must be the first key pressed in a data entry seque nce. If it is not the first data entered, t he arrow key is ignored.
2-8 If you have skipped t he above screen a nd want to get to it, simpl y the press the F1 key. If your skip th e opening screen and you want to check th e settings of the Terminal without having to r.
2-9 The prompt for Headphon e Volume is: HEADPHONE VOLUME Enter 0-9 for Volume Control Current Value is: 5 Automatic Check Back This parameter sho uld not be changed unde r normal circumstances. Aft er the host sends a prompt, the Terminal goes to sleep waiting on the operator to key or scan input in response to th e prompt.
2-10 characters can be useful if you need to differentiate between data that comes from a bar code versus data c oming from the keypad. • Enabling use of the Mod 43 check ch aracter r equires that th e last character of your bar code conf orm to the Mod 43 check character specifications.
2-11 2006) format, set the Laser Options param eter to D. To return to the default of normal EAN-13 transmission, set it to C . For details on ISBN, see Appendix J , UPC/EAN . • Use setting 4 and 9 to enab le transmission of the NSC character to your comp uter.
2-12 code used for the storage of computer data tapes. Enab ling the tap e label code ( C ) does not disable reading of Code 128 or Code 39 bar codes. • Bar Code ID’s are characters assigned to each bar code t ype to identif y that particul ar type of co de.
2-13 • Setting 2 requires that the last digit in your bar code conform to the specifications for the 2 of 5 check digit calculation. See Appendix I ; 2 of 5 Code fo r more information. • Transmiss ion of the ch eck dig it ( 5 ) requires the use of setting 2 and will transmit the check digit along with the bar code data to the computer.
2-14 • LabelCode5 and LabelCode4 are propriet ary bar code types used b y Follet. • If you have enabled t he Mod 10 o r Mod 11 chec k digits, t hey will be transmitted along with your bar code data from the RF Terminal to your host. • For more in formation re garding MSI or Plessey Code, see Appendix K ; MSI Plessey Code.
2-15 with the RF Terminal, th is will be set to Rechargeable before shipp ing. • If you didn't order re-chargeable ba tteries, this shipped settin g is Alkaline. Battery Status can be displayed by pressi ng the STATUS key on the RF Terminal keypad.
2-16 Voice Message Partitions This parameter partitions the to tal am ount of voice messages into differen t message lengths. The default setting is: 303015 xx yy zz where: xx is number of ½ second messages yy is the number of 1-second messages zz is the number of 2-second messages The total time allotted must not exceed 75 seconds.
2-17 • Double Decode is there to minimize the possibility of misreads when scanning very poor quality bar codes. This op tion forces the RF Terminal to keep reading un til it gets two results that are identical.
2-18 The following serial parameters B aud Rate, Par ity , Data Bits, and Stop Bits apply only to firmware updates and a po rtable printer such as the QL320 printers.
3-1 Chapter 3 Operational Theory Before you j ump in and start writing a complex h ost program, i t might be nice to be familiar with the theory behind the operation of your RF Terminal. Basic RF System communications… A WIFI RF Terminal system consists of three componen ts – Host Server , Access Points and RF Terminal .
3-2 When the Server recei ves a SIGN ON message from a RF Terminal, the Server transmits the SIGN ON information to th e host application program. The host application can th en do one of two things: 1. If it has something for the Terminal to do, it can send a prompt to the Terminal.
3-3 Can I change a prompt after it has been sent? Normally once the Terminal has receive d a prompt from the host, it goes to sleep and waits (as long as it takes) fo r the operator to scan or key something in response. The host cannot se nd another data entry pr ompt without creating a "Sequence Error.
.
4-1 Chapter 4 P erf ormance Issues Evaluating your area of planned operation Since every operational env ironment is different, it is impossible fo r us to tell you exactly what equipment you n eed and where you should put it to achieve maximum performance fr om your RF System.
4-2 covers, you won't have a p roblem. If you find a spot that none of the planned Access Poin t locations will cover, you will have to mov e one of the Access Points closer to the pr oblem spot or plan on addi ng another cl oser Access Point.
4-3 computer is located in a metal shed, you will need at least one Access Point located ou tside th e metal sh ed. • The more walls you try to transmit through, the more the signal breaks down.
.
5-1 Chapter 5 Bef ore y ou begin pr ogramming… The “Application Host Program” or “Server Program” is a progr am designed and written by the user that incorporates the WD802Term ActiveX con trol.
5-2 • Parse the Returned Strings thoroughly . Don’t assume anything about the nex t response from the Server to yo ur program and loo k only for the partial string such as the ID only. Parse the string returned comp letely, and be sure you are ex amining every possibility.
6-1 Chapter 6 Pr ogramming f or the 802 RF T erminal The programming support of fered for the 802 RF Terminal is an ActiveX drop- in component. Every necessary function is defined - you just complete the cod e for each function .
6-2 Methods are how you initiate communication with th e WD802Term object. You can re quest that a prom pt be sent to a t erminal, map a t erminal ID to a n IP address, a nd a variety of ot her services. Events are how the WD802Term object initiates co mmunication with your application.
6-3 Pick Item YY qty N Scan barcode: Enter Qty Picked: Of course you can see how you mi ght handle incorrect items o r wrong quantities by having your applicatio n generate prompts su ch as Incorrect .
6-4 promptline2 as string promptline3 as string NextIfError as integer NextIfOK as integer End Type dim TransactionSequence(10) as TransactionElement TransactionSequence(1).commandcode = 1 'InputAny TransactionSequence(1).promptline1 = "Go to Location " + GetLocationCode TransactionSequence(1).
6-5 Programming languages t hat can interf ace with the Active X tool include VB, C++, Delphi, Access, FoxPro, etc. If the Application Serve r receives any of: 1. 5 Addressing a Ter minal not SIGN ed ON messages in a r ow or 2. 5 Sequence Er rors in a ro w, or 3.
6-6 Test For Good Communication • Implemen t an event hand ler for OnTermSignIn that causes a beep or displays a message when called. If communication between the host PC and the terminal is good, your event handler will fire when your program is running and you sign in a terminal on your network.
6-7 Concepts – WD802Term ActiveX Drop-in components are tools that are added to yo ur programmi ng environment "t ool kit". Only the ActiveX variety are wi dely compatible with almost al l development environme nts.
6-8 Keep in mind that unless your terminal is configur ed with a static IP address, each tim e it is powered on it can have a dif ferent IP address (issu ed by your DHCP server ). Also, regardl ess of the termina l’s IP addr ess, it can be assigned a differ ent ID (by WD802Term) each time it Sig ns On to th e server.
6-9 Methods – WD802Term ActiveX Methods are commands that you issue t o the WD802term control. All of the " Inputxxx " commands cause the terminal t o wait for operator input. Note that your development environm ent may show more available methods for the WD802term contro l than are listed here.
6-10 InputScanner Parameters: line, position , prompt, allowbreakou t, timestamped Function: This instructs t he ActiveTerminal t o display t he prompt at line and position and wait for data to be entered from the terminal scann er only.
6-11 input can be by passed by pressi ng the enter key on the terminal which will send an empty data string to the host (fires the OnTermData event ha ndler). Data might be ! U1 MCR 80 T1 T2+ CR + LF (Refer to the Cameo manual for the exact string sequence you need to send.
6-12 SendDisplay Parameters: line, position, promp t Function: This instructs t he ActiveTerminal t o display t he prompt at line and position. Must be followed by an "Input" method call to take effect. ClearScreen Parameters: none Function: This instructs t he ActiveTerminal to clear its display.
6-13 ReInitAll Parameters: none Function: Instructs all attached terminals to re-initialize. OutputRaw Parameters: data Function: This allows you to over ride all of WD802Term’s Input methods (or any other method, for that matter) and send whatever data you want to the Active Terminal.
6-14 Events – WD802Term ActiveX WD802term events o ccur when a specific cond ition is met. When an even t is "fired", an event handler fun ction in your application is called .
6-15 OnTermNotSignedIn Data passed: terminal Event: A com mand has b een sent to a terminal that is not signed i n. OnTermSequenceError Data passed: terminal Event: Th e one-for-one host prompt/terminal response protocol has been violated. The host cannot send a second Input command until it has received a respon se from the f irst Input command .
6-16 OnTermLeftArrow Data passed: terminal Event: The left-arrow button has been pressed on a terminal. You must issue another Inpu t method call before WD80 2Term can res pond to anot her keypress on the terminal. If you have al ready entered some data on th e terminal and press an arrow key, this event w ill not fire.
6-17 Portable Printers Cameo and QL 320 Common Information Both of these printers are stoc ked by Worth Data for the conve nience of our users who need port able printi ng. These printers do not require any special pr otocol; the y do not re quire the “wake-up byte” as do ot her printers.
6-18 • When the Terminal sends data to th e host, it sends it in the following format: Terminal ID + DATA + CR Typically, the data is simply a st ring of characters, but in the instance of data coming from the magstr ipe reade r, there are some additional characters you need to be aware of.

7-1 Chapter 7 V oice Message Operations The 802 RF Terminal’s exclu sive use of voice prompts allows you to overcome problems such as literacy, langu age and lighting. With proper planning, voice prompting ca n enhance you r 802 RF Termi nal application, making it faster a nd simpler .
7-2 prompts or error messages will make it easier for the user to distinguish between them. • Be sure to record error messages for all possible proble ms that the user may encounter during a session. Once the operator becomes accustomed to listening to the voice prompts, it may become easy to overlook a “displ ay only” err or message.
7-3 Record/Playback--->1 Cloning Master----->3 Cloning Receiver-->4 Pressing the “ 1 ” ke y takes you int o the voice rec ording an d playback function. “ 3 ” and “ 4 ” allow you to clone voice messages fr om one 802 RF Terminal to an other.
