Introduction The 7001 RF T erminal is a low cost, eas y-to-use radio frequency interactive terminal which communicates with PCs (or any computer) by RS-232 serial port. This new term inal offers unprecedented power and ease of use, while maintaining compatibility with programs written for the older W orth Data T erminals.
• Speaker volume is controlled by the RF T erminal's S etup menu. • The 7000 Series does not have a choice of batter y types. It comes with a built-in Li-Ion recharge able battery . The battery is charged by the same power supply that is used with the Base Station.
Chapter 1: Installation Components The components in your RF T erminal system will vary according to the configuration of your system. Y our RF T erminal shipment should contain at least: • An RF T erminal T7001 or L T7001 - If the RF T erminal is an L T7001 model, it will have an integrated laser scanner built-in to the body of the terminal.
out to the serial port, which then passes this data on to the Base station. The Base station then broadcasts the message to the terminal, causing the terminal to displa y the message to the user .
RF T e rmi nal Operation Using the RF T erm inal keypad… The RF T erminal is turned on by pressing the green ON/OFF button located in the upper left- hand corner of the RF T erminal keypad. It is a good idea to fully charge the RF T erminal before you use it the first time to make sure the battery charged.

Filter Mode • Filter Mode • 0 – 3 4 • This option is only available on the L T701 1. • If you are trying to read poorly printed bar codes, this setting may improve the performance of the decoder . • Mode 0 is the default setting and works best with good quality bar codes.
Other Settings Preamble Preambles are user-defined data that is attached to the beginning of data (bar code or keyed) that is transmitted to the host by the RF T erminal. For example, if you set a preamble of @@ and scanned bar code data of 12345 , @@12345 would be transmitted to the host.
Postamble Postambles are user-defined data that is attached to the end of data (bar code or keyed) that is transmitted to the host by the RF T erminal. For example, if you set a Postamble of @@ and scanned bar code data of 12345 , 12345@@ would be transmitted to the host.
Characters This setting allows the RF T erminal to output chosen ASCII characters in place of the actual characters entered. For example, if you scanned the number 1 ( hex 31 ) and wanted the RF T erminal to output hex 92 instead, you would enter 3192 for the Characters parameter .

coverage in more than one location that is difficult to cover with a single base. An example of this would be inside two or more metal buildings where a base would be in one building and a relay in the other . Relays work like a remote antenna, passing data to the Base Station via cable instead of radio frequenc y .
Sometimes a Relay gets a response from the Base Station that is partial data or garbage. The T erminal retransmits its data since it has not received a new prompt. If this occurs ten times, the RF T erminal broadcasts, “who can hear me”. A t this point the Relay is still functioning and answers the RF T erminal’ s ca ll.
cable distance allowable. The gating factor for the application is almost always going to be the application pr ogram. By splitting the application between two or mor e work stations, each talking to a separate set of T erminals/Base Station, that factor can be minimized.
this is a common mistake. Failure to trap them will give create very strange, unpredictable results. Even though you don’t t hink your code will ever make a mistake, take advantage of feedback that the Base Station provides.
Programming for the RF T er minal The three levels of programming support offered for the RF T ermina l are: • Low Level ASCII s equences sent to and from the Base Station by the user program reading/writing to the serial port. • Active X drop-in components.

the statement, it will try to display the invalid statement on ID 0. Once the ENTER ke y is pressed on the T erminal displaying the invalid statement, the terminal sends the Base Station a “? ” character . The Base Station then in turn sends the message n ?CR (where n is the T erminal ID and CR is a carriage return) back to the Host computer .
Base Station to Host Formats The basic format of a message that is transmitted from Base to Host is fairl y simple: Byte position Function Possible values 1 RF T e rminal ID 0 -9, A-Z, a-z, - = 2+ Dat.
a valid command - remember that all messages must end with a request for data input. The host should then expect a response from the terminal of T erminal ID + DA T A (none if onl y pressing ENTER key) + CR .

A ut omatic Check Back When a terminal checks back in to see if there is a change in instructions, the host can send back the same prompt or send back a new prompt. The check back occurs according to the time specified in the T erminal's setup, (specified in increments of 5 seconds).
Control Keys for Possib le Programming There are some keys on the RF T erminal keypad that when pressed, can transmit special ASCII characters back to the host program. This feature might be used by a programmer to allow the operator to review transactions.
PromptCOM/ActiveX Drop-in components are tools that are added to your programming environment "tool kit". There are a variety of different technologies around for implementing a drop-in component such as V BX (for V isual Basic) and VCL (for Delphi and C Builder) and COM (ActiveX).
• Methods are function calls used to issue commands and access features of the drop-in component. An example of a method is sending an Input command to the terminal. • Events are function definitions placed in your applica tion’ s source code. The function definitions in your source code are called Event Handlers.
ComStopBits V alid values: 1, 2 Definition: This is a serial port setting and must match the base station setting. WDterm may allow other settings but those listed here are the onl y ones com patible with current version base stations.
InputKeyBd Parameters: line, position, pr ompt, shifted, timestamped InputKeyBdColor (15-line terminal only) Parameters: line, position, pr ompt, shifted, timestamped,FG,BG Function: This instructs the Active Ter minal to display the prompt at line and position and wait for data to be entered from the terminal ke y p ad only .
Function: This instructs the Active Ter minal to display the prompt at line and position and wait for data to be received through the terminal serial port. W aiting for serial input can be bypassed by pressing the enter key on the terminal which will send an empty data string to the host (fires the On Ter mData event handler).
SendFormat (15-line terminal only) Parameters: FGcolor , BGcolor Function: Sends to the Active Terminal the current Format Definition as created b y one or m ore calls to the DefineFormat method. It also sets the user-default display foreground and background colors.
T erminal ID is always passed as 0-63. A T er minal ID value of 99 indicates an error . Once you have the event handler skeletons, you can proceed to add whatever functionalit y y ou desire to each event. Y ou must call the OpenDevice method before an y events can be fired.

PromptNET TCP/I P Active X Controls Pro m ptNET/ActiveX is a drop in COM component that allows programmers to easily add the ability to send prompts to and receive data from their RF T ermina l via an RF Base Station across a TCP/I P network connection.
Before making any WDIPterm method calls in your application, make sure to set the ServerOn property to "true". T e st For Good Communication Implement an event handler for OnT ermBaseRegister that causes a beep or displays a message when called.

Portable Printers Cameo and QL 3 Common Information Both of these printers are stocked by W orth Data for the convenience of our users who need portable printing. These printers do not require any special protocol; the y do not require the “wake-up byte” as do other printers.
So, when the RF T erminal transmits the data to the host, it will be in the following format: RF T erminal ID + T1: D A TA + CR or RF T erminal ID + T2: D A TA + CR or RF T erminal ID + T1: D A TA + T2: DA T A + CR For fu rther i nfo rm ati on, see y our Pr inting Syste ms Pr ogr ammi ng Ma nual on the CD RO M s hip ped wi th th e pri nter .
V oi ce Message Operations The RF T erminal’ s exclusive use of voice prompts allows you to overcome problems such as literac y , language and lighting. W ith proper planning, voice pro mpting can enhance your RF T erminal application, making it faster and simpler .
1. Short messages are preferable for pro mpts; most English prompts can be stated in ½ second. Instead of saying, “Enter the Item Number ,” say “Item”. The ty pical RF T er minal operator does not want to hear long messages thousands of times.
T r oubl eshooting General Considera tions Site T est The most basic tool for troubleshooting is the Site T est at 50 feet range. (See Chapter 4 for the details on how to do a Site T est). If the Site T est fails at close range (50 feet), you have found the problem.

• Save the shipping box . If you ever need to send the RF T er minal or any of its parts back for repair , use this box. • Before you call your dealer or W orth Data for technical support, have your RF T erminal and related equipment in front of you and be prepar ed to explain your pr oblem in detail to the T echnical Support Engineer .
Appendixes Channel and Jumper Changes Opening a Base As preparation for changing the Channel on a Base Station or changing the Base to operate as a Rela y , the case must be opened to expose the circuit board with the switches and jumpers. Be sure you disconnect power before opening the case.
Channel Changes T o determine the current channel of a Base Station , power up the Base and watch the L ED light on the front of the unit. On power UP , a Base LED will blink "channel +3" times. For example, a unit that blinks 5 ti mes on power up is operating on channel 2 .
Adding Relays Connecting a Relay S tation How it works… A Rela y station allows you to extend the area of your RF coverage. Relays are connected by cable to the Base station, acting as a remote antenna. More than one Relay can be added b y “multi-dropping” additional Relays.
Routing the Wirin g The below diagram illustrates the RIGHT way to route your wiring and which units should be terminated. Notice this is the classical bus interface where the Base and Relays are connected to a “ one-cable bus”. The bottom of the Y -Cables is connected into the unterminated base or relay(s).
