QUICK START

The following can be used as a checklist to verify all of the steps necessary for complete installation of the DL Cordless Card™ for a DOS terminal and for a laptop (with two PCMCIA overlaid slots for PC cards of type II and with Windows 98, ME, XP, and later versions).

Installing to portable PC

1) Read all information in the section "Safety Precautions" at the beginning of this manual.

2) Start your PC.

3) Insert the DLCC correctly in the PCMCIA slot. Refer to the PC user's manual.

Figure 1 - Laptop Card Installation

A) Windows notifies the PC has a new hardware device (DLCC); B) Windows searches for a driver; C) Insert the enclosed installation CD-ROM and follow the procedure; D) At the end of the driver installation, Windows assigns DLCC a virtual

COM port.

4) Configure the DLCC address according to your application. See "Configuration Methods".

The default communication parameters of the COM port are: 9600 baud, no parity, 8 data bits, 1 stop bit, handshaking disabled

NOTE

The installation is now complete.

Installing to DOS Terminal

Read all information in the section "Safety Precautions" at the beginning of this manual.

1) Rhino™ will recognize the card if the correct drivers are loaded. Therefore, before inserting the card into the terminal make sure that:

- in NEWCFG.SYS the driver for the PCMCIA serial ports is loaded:

A:\PCMCIA\PCMSCD.EXE

- the scan engine driver is correctly configured (COM 3, interrupt 5) and

loaded after PCMSCD.EXE: A:\DRIVERS\REDIR.SYS -c3 -i5 -b3

The following is an example of the NEWCFG.SYS:

;Load PCMCIA drivers DEVICE=A:\PCMCIA\CNFIGNAM.EXE /DEFAULT DEVICE=A:\PCMCIA\PCMSSC40.EXE DEVICE=A:\PCMCIA\PCMCSFUL.EXE DEVICE=A:\PCMCIA\PCMRMAN.SYS DEVICEHIGH=A:\PCMCIA\PCMSCD.EXE

; Scan Engine Device Driver ; (Emulate SE1200 on Com3 @ 9600 N-8-1 Irq5) DEVICEHIGH=A:\DRIVERS\REDIR.SYS -c3 -i5 -b3

2) Insert the DLCC correctly in the PCMCIA slot. Refer to the terminal user's manual.

Figure 2 - DOS Terminal Card Installation

3) Start the DOS terminal. The system assigns DLCC a virtual COM port (COM 3, interrupt 5).

4) Configure the DLCC address according to your application. See "Configuration Methods" paragraph.

The default communication parameters of the COM port are: 9600 baud, no parity, 8 data bits, 1 stop bit, handshaking disabled

NOTE

The installation is now complete.

CONFIGURATION METHODS

DLCC configuration can be performed by four methods:

• DL Mobile Configurator™ to set the primary DLCC parameters;

• DL Sm@rtSet™ software configuration program;

• configuration strings sent from the Host via COM port;

• DLCARD.EXE DOS Configuration Program to perform a complete

configuration of DLCC.

Your card is supplied with its own Quick Reference Manual which provides basic application parameter settings using configuration strings, default values, and specific technical features. You can see either your card's Quick Reference Manual or this manual for

If you need to change the default settings for your specific application, see chapter 3 and the Examples in appendix A.

DL Mobile Configurator™

Through this Windows-based utility program it is possible to configure the terminal and set the primary DLCC parameters from a PC. To send the configuration to the terminal connect the PC to Rhino™ via RS232. For more details about this configuration method refer to the DL Mobile Configurator™ manual.

DL Sm@rtSet™

DL Sm@rtSet™ program, available on the Datalogic website, is a Windows-based utility program providing a quick and user-friendly configuration method. It allows defining the complete DLCC configuration and sending it directly to the card via virtual COM port. Connect to www.datalogic.com/services/support/ to download the software.

Configuration Strings from Host

This configuration method may be used for initial and complete configuration (see chapter 2) by sending the desired strings provided in chapter 3 through the COM port. Batch files containing the desired parameter settings can be prepared to configure the card quickly and easily. Reference notes describing the operation of more complex parameters are given in chapter 4.

initial configuration.

To use this manual for initial setup see chapter 2.

xii

DLCARD.EXE DOS Configuration Program

This configuration method allows setting DLCC through a vehicle mounted terminal running the DOS operating system. Upon start, the DOS DLCARD.EXE program checks communication with DLCC. If the test is successful, the program will open the file DLCARD.INI that includes a list of keywords. The keywords accepted are the following:

• RESET_CFG, to reset card configuration to default (possible values: TRUE or FALSE)

• ADDRESS, to set the DLCC address (range 0 to 1999)

• TERMINATOR, to set the terminator (possible values: CR, CR+LF or NONE)

• CMD, to send any command configuration string

Here is an example of DLCARD.INI file:

____________________________________________________________

[main] reset_cfg = TRUE address = 1973 terminator = cr

[commands] ;set minimum destination address cmd = $+MS1234$-

;set maximum destination address cmd = $+MT1235$-

____________________________________________________________

The DLCC will be set consequently.

In the DOS command line, if you launch the DLCARD.EXE program with the parameter /?, the list of all the possible parameters will be shown.

Example: C:\ DLCARD /?

INTRODUCTION

1 INTRODUCTION

The DL Cordless Card™ is a PCMCIA card developed to provide wireless 433 MHz RF communication between a laptop or a vehicle mounted terminal (Host) and Datalogic RF devices or base stations, which are STAR-System™ compatible:

Gryphon™ M Readers

Dragon™ M Laser Scanners

STARModem™ Radio Modems

Formula Basic Line RF Terminals (F734-E/RF, F725-E/RF, F660-E/RF)

STARGATE™ Base Stations

1.1 OVERVIEW

DLCC provides a wireless devices. DLCC installed in a vehicle mounted terminal is a Server (receiver) to the RF Devices and also a Client (transmitter) to STARModem, which receives data for the printer (Figure 3). STAR-System™ uses the Narrow Band RF radio and Datalogic CSMA/CA protocol to automatically link and manage all the RF devices in the system. This protocol manages the data transmission using a 16-bit CRC checksum. All RF devices in the system must implement the CSMA/CA protocol and therefore be configured using the STAR-System™ setup procedure.

INITIAL SETUP

2 INITIAL SETUP

For a correct DLCC configuration keep in mind the following:

• when using the DLCC for the first time, set the desired card address via COM Port, since its factory default address is "Undefined";

2.1 CONFIGURATION STRINGS

When using a DLCC on a terminal or a portable PC, initial setup can be performed via COM port by sending the configuration strings to the card using any terminal emulation program, for example Hyper Terminal.

Ensure that your PC COM port is set as follows: 9600 baud, no parity, 8 data bits, 1 stop bit, handshaking disabled.

NOTE

The programming sequence is the following:

SET RADIO ADDRESSES

Follow the procedure below to set the DLCC radio address and prepare it to receive and transmit data to all devices included in the range from the First to the Last destination device.

Enter Configuration

Set DLCC Radio Address xxxx = four digits for the DLCC address (from 0000 to 1999). This address must be unique.

RCxxxx

First Destination Device Address

xxxx = four digits for the Destination Device address (from 0000 to 1999).

Last Destination Device Address

xxxx = four digits for the Destination Device address (from 0000 to 1999). If transmitting to one Destination device only, this selection is not required.

Exit and Save Configuration

Step 4 and 5 can be omitted when the card is used only to receive data (Server).

When a range of cable-connected destination devices (i.e. a Stargate™ RS485 network) is defined, DLCC activates roaming towards all these devices.

4.1 RADIO AND SERIAL COMMUNICATION CONTROLS

DLCC communication can be controlled by several parameters depending on whether it is a Client or Server. DLCC can act as both Client and Server.

The following table summarizes which parameters are controlled by the Client and which ones are controlled by the Server.

Client (Transmitter)

controlled parameters:

Transmission Mode ACK/NACK Protocol ACK/NACK From Remote Host Handshaking FIFO Handshaking Single Store

To avoid incorrect interpretation of ACK characters, ACK/NACK Protocol and ACK/NACK From Remote Host cannot be

NOTE

To help understand the various communication control possibilities among the different communication modes, we will analyze the communication control parameter settings for the following 3 cases:

1) DLCC acting as Server

2) DLCC acting as Client (like an RF device)

3) DLCC as client / server

DL CORDLESS CARD™

DRAGON 1

HOST

DLCC

F734-E

DRAGON 2

DRAGON 3

Figure 5 –DLCC as Server

DLCC as a Server receives data from RF devices. The

ACK/NACK Protocol parameter can be set to assure correct communication between DLCC and the local Host.

Assuming the RF devices are setup for 2 way transmission in STAR-System™ mode we can analyze the following ACK/NACK protocol selections:

RF devices - Transmission Mode = 2 ways The Host must respond to a 2 way transmission

•

If DLCC - ACK/NACK = disabled there is no control of the communication between DLCC and the Local Host. DLCC answers the RF device which initiated the 2 way transaction with DATA received from the Local Host.

•

If DLCC - ACK/NACK = enabled when the Local Host receives a message correctly, it answers DLCC with the ACK character. Only then does DLCC acknowledge the RF device which initiated the 2 way transaction with an Empty Answer.

•

DLCC - DATA/NACK = enabled when the Local Host receives a message correctly, it answers DLCC with DATA. DLCC then answers the RF device which initiated the 2 way transaction with this DATA (i.e. command to RF device display).

PARAMETER ISSUES AND DEFINITIONS

Case 2 – DLCC as Client (like an RF device)

HOST

Client

Figure 6 - DLCC Client

In the figure above, DLCC is a Client (as an RF device). The following parameters may be set depending on the application:



STAR

Modem™ - ACK/NACK = enabled

STAR-System™ - Rx / Tx = enabled

•

If DLCC - Transmission Mode = 1 way

ACK/NACK from Remote Host = disabled FIFO = disabled Handshaking = modem (RTS/CTS)

In this case, DLCC sends data (messages) to the Remote Host. The special

case of FIFO disabled blocks transmission until an acknowledgement is received



from Host. Because ACK/NACK is enabled for STAR

Modem™, only after this has received an ACK from the Remote Host does it acknowledge reception (Empty Answer to DLCC).

Case 3 – DLCC as Client / Server

DL CORDLESS CARD™

Client

HOST 1

HOST 2

Server

Figure 7 – DLCC as Client / Server

Both DLCCs are able to communicate bi-directionally. For analysis purposes only, we assume the situation where Host 1 is Client and Host 2 is Server. It is clear that the situation is analogous in the opposite direction:

•

If DLCC 1 - Transmission Mode = 1 way

ACK/NACK from Remote Host = disabled FIFO = enabled Handshaking = any

The Client, (Host 1) sends a message to the Remote Host (Host 2), but no

control exists upon reception and even if ACK/NACK Protocol is implemented on the Server side (Remote Host), no answer is returned from DLCC 2 to DLCC 1. This is not a secure communication.

•

If DLCC 1 - Transmission Mode = 1 way

ACK/NACK from Remote Host = enabled FIFO = enabled Handshaking = any

The Client, (Host 1) sends a message to the Remote Host (Host 2). DLCC 2

acknowledges good radio reception but no control is made on Remote Host reception. If DLCC 2 acknowledges radio reception within the Radio Protocol Timeout, DLCC 1 sends ACK to its local Host, otherwise it sends NACK.

PARAMETER ISSUES AND DEFINITIONS

•

If DLCC 1 - Transmission Mode = 2 ways

ACK/NACK from Remote Host = enabled FIFO = enabled Handshaking = any Single Store = enabled

The Client, (Host 1) sends a message to the Remote Host (Host 2) and expects

an answer from Host 2. Host 2 answers with DATA (a string of up to 238 characters). If DLCC 2 sends this DATA answer within the Radio Protocol Timeout, DLCC 1 sends it to its local Host (Host 1), otherwise DLCC 1 sends NACK. In addition, the Single Store parameter upon Radio Protocol timeout, causes DLCC 1 to retry transmission of the same message the defined number of times, before responding to its local Host (Host 1) with NACK.

Host 1 - Handshaking = RTS/CTS

•

If DLCC 1 - Transmission Mode = any

ACK/NACK from Remote Host = enabled FIFO = disabled Handshaking = modem (RTS/CTS)

The Client, (Host 1) sends a message to the Remote Host (Host 2). DLCC 1

after receiving the message, blocks transmission of Host 1 until communication is completed according to the other communication control parameter settings as described above.

The most secure settings for bi-directional communication is to have ACK/NACK from Remote Host enabled and Two-way transmission at both ends. In addition, in case the first transmission fails, the Single Store parameter automatically repeats transmission of the same data

4.2.2 ACK/NACK Protocol

This parameter sets a transmission protocol which takes place between DLCC (Server) and an RF device. An RF device (such as a hand-held reader) passes its data (code read) to the card installed into the terminal. The Host sends an ACK character (06 HEX) to the card in the case of good reception; a NACK character (15 HEX) requesting re-transmission is sent to the card in case of bad reception.

In the particular case where the RF device is configured for 2 way transmission and therefore requires an answer, it is advised to set DLCC with the DATA/NACK protocol. The DATA answer from the Local Host is implicitly considered an ACK and is sent to the RF device. If instead ACK/NACK is used, the card generates an Empty Answer to the RF device.

Before selecting this parameter ensure that “ACK/NACK from Remote Host” is disabled (see par. 4.4.5).

PARAMETER ISSUES AND DEFINITIONS

If the card does not receive an ACK, DATA or NACK, transmission is ended after the RX Timeout (see par. 4.2.3 ). See also Radio Protocol Timeout, par. 4.4.3, for radio transmission to RF devices.

For ACK/NACK selection when DLCC as Client, is transmitting to a destination device connected to a Remote Host, refer to par. 4.1.

4.2.3 RX Timeout

This parameter can be used to automatically end data reception from the Local Host after the specified period of time.

If no character is received from the Local Host, after the timeout expires, any incomplete string is flushed from the card buffer.

Refer to par. 4.2.5 for RX Timeout functioning when defining the frame packing.

4.2.4 FIFO

If enabled, the Destination Device collects all messages sent by DLCC and sends them in the order of acquisition to the connected Remote Host.

If disabled, DLCC blocks the message transmission from the Local Host until an answer signaling the right/wrong message transmission has been received from the Destination Device (1 way) or the Remote Host (2 way). Once the answer has been received, the Local Host is allowed to send a new message.

This command requires the modem (RTS/CTS) handshaking to be enabled.

For more details about the Transmission Mode refer to par. 4.4.2.

4.2.5 Frame Packing

This parameter defines the format of the frame to be transmitted

Host.

the The frame received by DLCC may contain a maximum of 238 characters. All characters not included within this number will be transmitted from the Host in a new frame.

PARAMETER ISSUES AND DEFINITIONS

Correct FRAME identification is managed by frame packing. Three different types of frame packing can be selected:

•

Frame+ [CR]

(default)

: the frame sent to DLCC is terminated by [CR]. This means you cannot use the [CR] character within the frame. In Frame + [CR] mode, make sure the FRAME does not contain [CR], nor begin with $+ or #+ characters.

FRAME [CR]

The frame transmitted by DLCC has no additional field. In this case the end of

the FRAME is either DATA or Terminator if any.

FRAME

•

[STX]+LEN+Frame+[CR]: both frames sent to and by DLCC are preceded by [STX], LEN and terminated by [CR], where LEN is a field of 4 digits and indicates the FRAME length in number of characters, that is FRAME +CR.

[STX] LEN FRAME [CR]

In this mode, it is not necessary to use the Frame Packing to send commands.

(i.e. $+$&[CR]).

The [STX], [CR] and [ESC] characters contained in the frame must be preceded by the [ESC] character for a correct transmission.

•

Frame after Timeout: if the delay between two consecutive characters is more than the selected timeout, the card considers the frame completed. The timeout corresponds to 1/10 of the value defined for RX Timeout (see par. 4.2.3). Therefore, the timeout for frame packing is calculated in ms (from 10 ms to 990 ms).

It is not possible to disable this timeout, therefore possible values are in the range 10 - 990 ms. If RX Timeout is disabled,

NOTE

Frame after Timeout is 10 ms.

Both the frames sent to and by DLCC have no additional fields:

FRAME

All commands to be sent using this frame packing must be preceded by the

string below, which substitutes the $+ character:

#+++PROG_REQ+++#

DL CORDLESS CARD™

This string is always transmitted in a single frame preceding the one containing

the configuration command, as shown in the following examples:

Example 1

Sending the $+$![CR] command to transmit the card software release:

Frame = #+++PROG_REQ+++#

Frame = $![CR]

Example 2

Sending the $+ML0$-[CR] command to set the default frame packing

configuration:

Frame = #+++PROG_REQ+++#

Frame = ML0$-[CR]

4.3 DATA FORMAT

4.3.1 Header/Terminator Selection

The header/terminator selection is not effected by restore default command.

Figure 10 - Transmitting a Message in 2 Way Mode

The Address Stamping parameters consist of a 4-digit number in the range 0000-

1999.

When the card receives data in 2 way mode from more than one RF device, it is advised to enable Address Stamping for correct radio transaction management.

NOTE

If communicating with only one RF device in 2 way mode, Address Stamping is not required, since the data/answer generated by the Host is only sent to that device. In this case DLCC can receive data

NOTE

(messages) via radio only after sending the 2 way answer.

4.3.3 Address Delimiter

The Address Delimiter allows a character to be included to separate the Address stamping fields from the next fields in the message. Once enabled, it is required to set the Host application to include the Address Delimiter character in the message. Any character can be included in the hexadecimal range from 00 to FE.

PARAMETER ISSUES AND DEFINITIONS

4.4 RADIO PARAMETERS

4.4.1 RF Baud Rate

This parameter defines the baud rate used for radio communication. The baud rate value can be set to 9600 or 19200 according to the device communicating with DLCC. 19200 is the default value.

4.4.2 Transmission Mode (Client only)

DLCC Client can communicate within the system using two different transmission modes:

•

1 way mode: (default)

•

2 way mode:

DLCC transmits data without requiring an acknowledgement answer from the Remote Host (see par. 4.1 for details).

DLCC transmits data requiring an acknowledgement answer from the Remote Host (see par. 4.1 and par. 4.4.5 for details.

4.4.3 Radio Protocol Timeout (Client only)

This parameter sets the valid time to wait before radio and a destination device is considered failed.

This parameter should be set taking into consideration the radio traffic (number of devices in the same area).

If the RS232 interface connecting the Remote Host and the destination device is used with ACK/NACK enabled, this parameter should be at least equal to the RX Timeout parameter for low traffic environments. It should be increased if there are many devices in the same area.

transmission between DLCC

4.4.4 Single Store (Client only)

This command is active when DLCC (Client) destination device. It guarantees a secure control to prevent the transmission of duplicated data. If Single Store is enabled and DLCC does not receive any answer of good transmission from the destination device, it enters a special operating mode that stops sending new messages. When such operating mode is entered, the card retries transmission itself for the number of attempts selected in the configuration.

transmits messages/data to a

DL CORDLESS CARD™

Once the transmission is successful, the card continues to send new messages. If transmission is not successful after the number of configured attempts, the message is lost. To be absolutely sure that messages are received by the destination device, set Single Store to continuous. A new message will not be sent unless the previous one is received. If using Single Store as continuous, and the transaction is not received, check that the Server is active and that the DLCC configuration is correct. If your application requires an acknowledgement from the Remote PC, you must define Single Store and enable ACK/NACK From Remote Host (see par. 4.4.5).

4.4.5 ACK/NACK From Remote Host (Client only)

This parameter sets a transmission protocol which takes place between the DLCC (Client) Host and the destination device Host (Remote Host). The transmission is influenced by the transmission mode selected (see par. 4.4.2).

Before selecting this parameter ensure that “ACK/NACK Protocol” is disabled (see par. 4.2.2).

CAUTION

One way mode:

Host sends a message to DLCC which passes it to the destination device via radio. In case of good transmission, the destination device transmits a radio acknowledgement back to the card. If received before the Radio Protocol Timeout expires, DLCC sends an ACK character to the Host. If the timeout expires before receiving any acknowledgement, the card transmits a NACK character.

PARAMETER ISSUES AND DEFINITIONS

Two way mode:

Host sends a message to DLCC which passes it to the destination device via radio. The destination device transmits the message to the Remote Host which responds with DATA. This answer is sent to DLCC through the destination device. Then, the card transmits it to the Host. If the Radio Protocol Timeout expires before the answer from Remote Host is received by DLCC or in case the Remote Host does not respond, DLCC sends a NACK character to the Host.

functioning.

4.4.6 Beacon (Client only)

If this parameter is enabled, DLCC polls the server for data at regular intervals (configurable from 2 to 30 seconds) by sending a character ENQ (ASCII 05) with a 2 way transaction. The server must always respond with data or with an Empty Answer. The selection of this parameter does not influence the card normal radio transaction. This means that it does not modify the transmission of data sent by the Local Host.
