Interference

Pacemakers, Hearing Aids and Other Electrically Powered Devices

Most manufacturers of medical devices adhere to the IEC 601-1-2 standard. This standard requires devices to operate properly in an EM Field with a strength of 3V/m over a frequency range of 26 to 1000MHz.

The maximum allowable field strength emitted by the Dolphin is 0.3V/m according to Subpart B of Part 1 of the FCC rules. Therefore, the Dolphin RF will have no effect on medical devices that meet the IEC specification.

Microwaves

The radio in the Dolphin RF terminal operates on the same frequency band as a microwave oven. Therefore, if you use a microwave within range of the Dolphin RF terminal you may notice performance degradation in your wireless network. However, both your microwave and your wireless network will continue to function.

The Dolphin Batch terminal does not contain a radio, and therefore, is not affected by microwave ovens.

Batteries

•

Use only the battery supplied with your Dolphin or a replacement battery supplied, recommended, or approved by HHP.

• Replace a defective battery immediately as it could damage the Dolphin

terminal.

• Never throw a used battery in the trash. It contains heavy metals and should

be recycled according to local guidelines.

• Don’t short-circuit a battery or throw it into a fire. It can explode and cause

severe personal injury.

• Excessive discharge damages a battery. Recharge the battery when your

Dolphin indicates low battery power.

• Although your battery can be recharged many times, it will eventually be

depleted. Replace it after the recommended usage period (about 500 charge cycles for the 1500 mAh NiMH battery) or if the battery does not hold a charge.

• If you are not sure the battery or charger is working properly, please send it to

HHP or an authorized HHP service center, for inspection.

The Dolphin handheld computer/bar code scanner meets or exceeds all applicable standards and has been manufactured to the highest level of quality.

Turning On the Dolphin

1. Install the charged battery pack in the Dolphin.

2. Hold the Dolphin in the palm of your hand so that you can press the ON/SCAN

key easily with your thumb.

3. Press the ON/SCAN key to turn the Dolphin on. Your Dolphin will boot up just

like a desktop PC and the title screen for the HHP Demo Application will appear on the display.

If the title screen does not appear on the display of your Dolphin, the HHP Demo Application has been removed from your terminal. Therefore, you will see a DOS prompt on the screen. Example: C:\ or A:\ .

Note: If using the Dolphin for first time or if the terminal has been without a battery pack for more than 30 minutes and you are now inserting a battery, you may receive a CMOS error when the terminal boots up. Don’t worry, the terminal is OK. This simply means that the internal back-up battery needs to be recharged and the date and time need to be reset. To recharge the internal backup battery and reset the date and time, insert a fully charged battery in the Dolphin and then use the DOS date and time function to set the correct date and time. The internal back-up battery requires a minimum of 5 hours of charging time in order to perform and maintain the system as described on page

30.

Turning the Dolphin Off

The Dolphin is never actually turned off. To conserve power, the Dolphin goes into “sleep mode” when it is inactive for a programmed period of time as defined by your application. The screen is blank when the Dolphin is in “sleep mode.”

CHAPTER 2 DOLPHIN BASICS

Maintaining the Dolphin’s Batteries

CAUTION: Use only the 3.6V battery packs provided by Hand Held Products. The use of any other battery pack in the Dolphin 7200 terminal will void your warranty and may result in damage to the Dolphin terminal or battery.

There are two batteries in the Dolphin:

Internal NiMH Backup Battery

Located inside the Dolphin, this battery backs up the RAM and clock when the NiMH main battery is discharged or removed from the terminal.

NiMH Battery Pack

The battery pack is the primary power source for operating the Dolphin.

Internal NiMH Backup Battery

The Dolphin’s internal backup battery prevents the terminal from being reset if you need to remove and replace the main battery pack. The battery retains RAM data and allows the real-time clock to remain operational for up to 30 minutes when the battery pack is removed. If the internal back-up battery becomes discharged of power, it requires a minimum of 5 hours of charging time in order to perform and maintain the system as described above.

NOTE

Return the Dolphin to

an authorized service

center when the

internal battery needs

to be replaced.

The internal backup battery is charged by the Dolphin’s main battery pack. If the terminal is left without the main battery pack for more than 30 minutes, the internal backup battery needs to be recharged.

Note: Data and programs on Drives C and D remain safe even if the internal backup battery fails. However, you must reset the real-time clock using the DOS Time and Date function.

Follow these guidelines to maximize the life of the Dolphin’s backup battery:

• Keep a charged NiMH battery pack in the Dolphin. The internal battery

will prematurely discharge if there is not at least a partially charged battery in the terminal.

• Put the Dolphin in the HomeBase when the terminal is not in use.

NOTE

Keep a charged

battery pack in the

Dolphin at all times to

conserve the internal

back-up battery.

CHAPTER 2 DOLPHIN BASICS

NiMH Battery Pack

The 3.6V, 1500 mAh Nickel-Metal-Hydride (NiMH) battery pack is the primary power source for the Dolphin. Other Nickel-Metal-Hydride batteries may be approved by Hand Held Products, Inc. to work with your Dolphin. Contact Hand Held for more information.

The 1500 mAh NiMH battery is designed to operate in temperature range of –10 to 50 °C (14 to 122° F). For maximum performance, charge the batteries between 10 and 35 °C (50 and 95° F).

WARNING: Although the Dolphin 7200 terminal is received with the battery inserted, it is NOT ready for charging and/or deep-cycling. Remove the plastic insulator located between the

terminal and battery connectors. Failure to remove the insulator may result in damages to the terminal.

Performance specifications for a fully charged 1500 mAh NiMH battery (using power management function calls within application):

Up to 20 hours of usage in a Dolphin Batch terminal with a full battery charge

NOTE

For maximum battery

life, Hand Held

Products recommends

that you deep-cycle

(service) the battery

twice before initial use and then, once a month

thereafter.

Up to 10 hours of usage in a Dolphin RF terminal with a full battery charge

Up to 20 hours of usage in a Dolphin 2D terminal with a full battery charge

Keep a charged battery pack in the Dolphin at all times to conserve the internal backup battery. When you remove a battery pack, insert another battery pack in the Dolphin. The internal battery will prematurely discharge if there is not at least a partially charged battery in the terminal.

Servicing the Battery Pack

For maximum battery life, Hand Held Products recommends that you deep-cycle the battery twice before initial use. It is also recommended that you service, or calibrate the battery once per month. To deep cycle, insert the battery into the HomeBase auxiliary battery well. Then, push and hold the Service Aux Batt button for at least 4 seconds. For more information, see the section on the Service Aux Batt feature of the HomeBase in Chapter 7.

You may also deep cycle the battery using the CycleBat battery utility conditioning software which is available from the Partners area of the Hand Held Products website,

http://www.hhp.com/

. More information on this utility is available from the help file

that comes with the software.

CHAPTER 2 DOLPHIN BASICS

Charging the Battery Pack

You can recharge an individual battery pack using the auxiliary battery well of the Dolphin HomeBase, or the Dolphin 10-Slot Multiple Battery Charger. Both accessories use a charging method that senses when the battery pack is fully charged and then drops to a trickle charge to keep the battery pack at full capacity.

For more details, see the section on Charging Batteries in the HomeBase in Chapter 7.

Storing Batteries

To maintain top performance from batteries, follow the guidelines below when storing them:

• Avoid storing batteries outside of the specified range of -4 to 104° F

(-20 to 40°C) or in extremely high humidity.

• For prolonged storage, do not keep batteries stored in the terminal.

• During long-term storage, battery deactivation may tend to occur which

may cause charging to stop early during recharging after storage. Charging and discharging the battery several times can handle this issue. Also, the first charging after prolonged storage may yield a lower than normal capacity. While this will vary depending on the storage conditions, charging and discharging the battery several times will almost completely restore capacity.

CHAPTER 3 DOLPHIN 7200 RF HANDHELD COMPUTER

About the Dolphin 7200 RF Handheld Computer

The Dolphin 7200 RF® terminal integrates the basic functionality of the Batch terminal with an 802.11b or a WLIF™ interface that allows the terminal to communicate with a host computer via a wireless local area network (WLAN). Both radio options operate in the 2.4 GHz frequency band. Terminal emulation software and keypad overlays for IBM 3270, IBM 5250 and DEC VT100/220 emulation are available for both radio options. The terminal’s DOS compatible 386 microprocessor is easy to program and developers can create wireless applications linked to a host PC, using RF Simplicity® and MS Visual Basic™.

Refer to Chapters 1 and 2 in this manual for more on basic operation of the Dolphin terminal and accessories available.

802.11b-Compliant Dolphin 7200 RF Terminal

The 802.11b-compliant Dolphin 7200 RF incorporates a Cisco® 802.11b Micro-ISA radio. The radio uses direct sequence spread spectrum (DSSS) technology, which spreads its signal continuously over a wide frequency band, and provides an Ethernetlike data rate of up to 11 megabits per second. The radio may also provide up to 128bit Wired Equivalent Privacy (WEP) encryption. WEP is used to encrypt and decrypt data signals transmitted between Wireless LAN (WLAN) devices. It is an optional security encryption mechanism defined within the 802.11 standard that makes a wireless LAN link as secure as a traditional wired link. The optional WEP security mechanism is available with 128-bit or 40-bit encryption.

Dolphin 7200 RF is interoperable with other 802.11b compliant products to allow network expansion as needed. It can be connected to other devices, such as printers and PCs via PC-card adapters.

Setting WEP Modes And Keys On The 802.11b Radio Card

This section describes how to set WEP (Wired Equivalent Privacy) modes and keys on the Cisco® 802.11b radio card.

WEP is used to encrypt and decrypt data signals transmitted between Wireless LAN (WLAN) devices. WEP is an optional IEEE 802.11 feature used to provide data confidentiality that is equivalent to the confidentiality of a wired LAN that does not employ crypto techniques to enhance privacy. WEP makes a wireless LAN link as secure as a wired link.

The wep.bat utility is used to set WEP modes and keys for the Cisco® 802.11b radio card. The wep.bat file uses three files:

wepdos.exe – an executable file that configures WEP values for the Cisco radio

keys.exe – an executable file that calls the functions for setting WEP values

cscpkt.ini – a configuration file for the Cisco radio

All four files are located in the Dolphin c:\rf directory that is part of the stackcsc.exe file.

If the user will be setting WEP keys using the batch mode, the user must create a keys.txt file using a text editor such as Notepad and then copy it to the c:\rf directory. This file will contain the encryption keys used when operating in WEP mode. For obvious security reasons, this file will be automatically deleted upon running the wep.bat utility. HHP recommends that you verify that the keys.txt file has been deleted.

Refer to the Cisco documentation for complete descriptions of the various WEP modes. The current radio card may not support some modes.

CHAPTER 3 DOLPHIN 7200 RF HANDHELD COMPUTER

Running the WEP.BAT Utility

This section describes usage and command line options for the WEP.BAT utility.

NOTE

Reset the Dolphin terminal by pressing and releasing the <SHIFT>, <ON/SCAN>

WEPSHARED Sets WEP mode to WEPSHARED. In this

mode, the Access Point sends a plain-text, shared-key query to any device attempting to communicate with the Access Point.

WEPOPEN (default) Sets WEP mode to WEPOPEN which

allows any device, regardless of its WEP settings, to authenticate and then attempt to communicate with the Access Point.

CHAPTER 3 DOLPHIN 7200 RF HANDHELD COMPUTER

Example 1: To configure WEP using the batch mode, create the keys.txt file using a text editor as shown:

Sample ASCII keys.txt file for 40-bit encryption where x is the key code:

ASCII xxxxx xxxxx xxxxx xxxxx xxxxx

Sample HEX keys.txt file for 128-bit encryption where x is the key code:

HEX xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxx

After creating the keys.txt file, copy it to the c:\rf directory and enter:

C:>\WEP BATCH

Result: The WEPOPEN operating mode is automatically set (the WEP mode can be changed using commands shown later in this document). One of the following messages will display on the terminal:

Need keys.exe and keys.txt (if both files are not present)

Error(s): Retry (if error occurred writing to radio card)

Done (if keys successfully set)

CHAPTER 3 DOLPHIN 7200 RF HANDHELD COMPUTER

Example 2: To set the WEP keys using an ASCII character string via the Dolphin terminal keyboard, enter

C:\> WEP ASCII 11111 X 33333 X

There are four WEP keys to set. To skip a key code, enter <X> for each blank entry. In the example above, only keys 1 and 3 have a value; 2 and 4 have no value. An ASCII character string of 5 characters sets 40-bit encryption and 13 characters sets 128-bit encryption on the terminal.

Result: This will set key1 to 11111 and key3 to 33333. Keys 2 and 4 are not set. 40 bit WEP will be used. The terminal will display one of the following screens:

Error(s): Retry (if an error occurred writing to radio card)

Done (if keys successfully set)

Example 3: To configure WEP using a HEX string via the Dolphin terminal keyboard, enter:

C:\> WEP HEX 11111111111111111111111111 X X X

There are four WEP keys to set. To skip a key code, enter <X> for each blank entry. In the example above, only key 1 has a value; 2, 3 and 4 have no value. A HEX string of 10 characters sets 40-bit encryption and 26 characters sets 128-bit encryption.

Result: Sets key1 to 11111111111111111111111111. Keys 2, 3 and 4 are not set. 128 bit WEP will be used. The terminal will display one of the following screens:

WLIF™-Compliant Dolphin 7200 RF Terminal

The WLIF-compliant Dolphin 7200 RF™ terminal incorporates a high performance radio that uses frequency hopping spread spectrum technology compliant to the Proxim ® WLI Forum/OpenAir™ specification. The radio operates at a data rate of up to 1.6 megabits per second, with 15 independent channels available.

Frequency hopping technology is inherently secure in that the signal hops among a variety of frequencies and, at any instant in time, the signal is broadcast on only one frequency. The transmission remains on each frequency for only a short period (up to

0.4 second) before moving to the next frequency.

Dolphin 7200 RF is interoperable with all WLIF-compliant products to allow network expansion as needed. It can be connected to other devices, such as printers and PCs via PC-card adapters.

CHAPTER 6 DOLPHIN 7200 2D HANDHELD COMPUTER

About the Dolphin 7200 2D Hand Held Computer

The Dolphin® 7200 2D hand held computer features the IMAGETEAM ™ 4250 Image Engine, a low power, high-resolution digital image engine for omni-directional and auto-discrimination reading and decoding of linear barcodes, stacked linear (PDF417) and 2D matrix codes. The image engine functions like a digital camera and also provides OCR (Optical Character Recognition) functionality.

The terminal is available in several configurations with alphanumeric and numeric keyboard options. These configurations include the standard range (LR), long range (LX), and high-density (HD) engines with 2MB RAM and 8MB non-volatile FLASH memory.

The 2D terminal has image lift capabilities for signature capture and proof of delivery applications. Images taken with the unit can be compressed and stored using industrystandard data compression technologies. The device provides the flexibility to store either images that contain grayscale information or black and white only information. Images can be downloaded via HomeBase™ or VehicleBase™ communication cradles and then transmitted via one of many wired or wireless options.

The terminal is also able to decode barcode symbologies and capture images in dim lighting conditions or complete darkness.

Supported Symbologies

1D linear codes:

Code 3 of 9, Interleaved 2 of 5, TLC Code 39, Code 11, MSI, UPC A, UPC EO, UPC EI, EAN/EAN13, Codabar, Code 128, Code 93, UPC

2D codes:

CHAPTER 6 DOLPHIN 7200 2D HANDHELD COMPUTER

Reading Barcodes

The omni-directional scanning capabilities of the Dolphin 7200 2D terminal greatly simplify operation and training and increase productivity. To read a bar code:

1. Press the ON/SCAN button to project the scanner’s bright red aiming beam

2. Center the aiming beam over the barcode. The red SCAN LED illuminates when the user presses the ON/KEY key and the green DECODE LED illuminates when a bar code is successfully decoded. The aiming beam can

be positioned in any direction for a good read.

Linear bar code 2D Matrix symbol

The aiming beam is smaller when the terminal is held closer to the code and larger when it is farther from the code. Symbologies with smaller bars or elements (mil size) should be read closer to the unit. Symbologies with larger bars or elements (mil size) should be read farther from the unit.

CHAPTER 6 DOLPHIN 7200 2D HANDHELD COMPUTER

Capturing Images

The image-capture process is a split-second operation for experienced users. By following the basic guidelines, new users can easily develop their own technique and, with practice, quickly learn to adapt it to different circumstances. The basic steps for acquiring images using the Dolphin 7200 2D terminal are:

1. To aim, hold the Dolphin terminal horizontally at a 45° angle approximately 2 to 9

inches (5 to 20 cm) away from the target. You may have to adjust the angle at which you hold the Dolphin if there is glare on the screen.

2. Press the ON/SCAN button to take an image. Use the live video image on the

terminal screen as a guide for positioning and aiming the terminal at the target. You may find it helpful to start by moving the terminal further away and then in closer to the target. The active screen image will have a slightly degraded appearance compared to the captured image. This is normal.

3. Release the ON/SCAN button to capture the image when the desired image is

displayed on the terminal screen. Hold the Dolphin terminal as still as possible when capturing the image.

The image quality and related file size is determined by the data compression method used by your software application. For highest quality, take grayscale images. When saved, the image will be saved in JPEG file format. The size of the file depends on the information content of the image and will be approximately 4-8 K.

Lighting Conditions

The Dolphin 7200 2D terminal is designed to read bar codes and take images in dim light conditions. It is suggested that you turn on the unit’s electroluminescent display backlight when taking images in extreme low light conditions to help with aiming.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

Hub of the System

As the hub of your Dolphin system, the Dolphin 7200 HomeBase performs three important functions – battery management, communications and storage.

Battery Management

The Dolphin 7200 HomeBase uses a charging method that senses when the battery pack is fully charged and then drops to a trickle charge to keep the battery pack at full capacity. The battery pack does not need to be discharged before recharging because this method protects the battery from damage caused by overcharging.

IrDA Optical Communications

The IR communications port on the HomeBase connects with the IrDA port on the Dolphin. Reliable data communications at speeds of up to 115 baud can be transmitted by the HomeBase. With no pins or contacts to break, IrDA will work reliably for years.

The Dolphin 7200 HomeBase can be networked together for mass programming and charging. Units are individually addressable, allowing each HomeBase to be automatically loaded with the right information and files for its user.

Convenient Storage

The Dolphin 7200 HomeBase is a safe and convenient storage receptacle for the Dolphin terminal. The HomeBase also holds a spare charged battery pack.

CAUTION: Use only the 3.6V battery packs provided by Hand Held Products. The use of any other battery pack in the Dolphin Terminal will void your warranty and may result in damage to the Dolphin Terminal or battery.

NOTE

For maximum battery life,

Hand Held Products

recommends that you deep-

cycle (service) the battery twice before initial use

and then, once a month

thereafter.

With the Dolphin HomeBase, you can charge a Dolphin terminal and a spare NiMH battery pack simultaneously. The HomeBase charges the terminal and the spare battery pack independently.

When you insert a battery into the Dolphin HomeBase, it charges the battery at the highest rate possible. The HomeBase uses a charging method that senses when the battery pack is fully charged and then drops to a trickle charge to keep the battery pack at full capacity. You do not need to discharge the battery pack before recharging because this method protects the battery from damage caused by overcharging. A dead battery will charge to full capacity in approximately three hours.

The Dolphin Terminal can be stored indefinitely in the HomeBase without damage to the terminal, battery packs, or the HomeBase. Keep the HomeBase plugged in so that the Dolphin Terminal’s battery pack stays fully charged.

Charging A Dolphin Terminal

1. Insert a battery pack into the Dolphin Terminal.

2. Place the terminal, laser engine window up and the LCD visible, in the Dolphin

Terminal Well of the Dolphin HomeBase.

3. Let it glide down into the well until it stops.

4. Once the Dolphin Terminal is properly seated, the Charging Main Batt LED on

the HomeBase will be solid GREEN.

Once the battery is inserted into the Dolphin HomeBase you can use the CHARGING AUXBATT LED to monitor the charging progress. See Figure 10 for a summary of each charging state.

Deep-cycling the Battery

For maximum battery life, Hand Held Products recommends that you deep- cycle (service) the battery twice before initial use and then, once a month thereafter. To deep-cycle, insert the battery into the HomeBase auxiliary battery well. Then, push and hold the Service Aux Batt button for at least 4 seconds. The deep-cycling process takes approximately 6.5 hours.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

The CHARGING AUXBATT LED is red while the battery is discharging and changes to blinking red when the charging cycle begins and orange when charging at the maximum rate. The battery is ready to use when the light turns green. See Figure 10 for more on the LED status.

Setting Up For Communications

The Dolphin Terminal and Dolphin HomeBase support RS-232 communications through the RS-232 Main Communications Port located on the side of the Dolphin 7200 HomeBase. The HomeBase translates the RS-232 signals from the host computer into infrared signals to communicate with the Dolphin Terminal.

The HomeBase RS-232 interface allows the Dolphin Terminal to communicate to a personal computer, modem, or any standard RS-232 device using a standard serial cable and communications software.

Follow these steps to set up the Dolphin HomeBase and Dolphin Terminal for communications:

1. Set-up the Dolphin HomeBase.

2. Set-up the Dolphin Terminal.

3. Follow the data transfer sequence as described by your application.

Setting up the Dolphin HomeBase

Set the Dolphin HomeBase on any dry, stable surface such as a desktop. Before mounting the Dolphin HomeBase, check to ensure that all AC wall transformers have a nearby electrical outlet. Be sure to provide enough workspace with good lighting for the user to view and operate the Dolphin Terminal while it is in the HomeBase. Setting up the HomeBase involves three steps:

1. Connecting the cables

2. Setting the configuration switches

3. Setting the baud rate

Connecting the Cables

Connect the HomeBase to the host computer or other device by plugging an RS-232 serial cable into the RS-232 Communications Port on the rear of the HomeBase. The

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

wiring of your cable depends on whether the other device is set up as a DCE (Data Communications Equipment) or DTE (Data Terminal Equipment) device.

The HomeBase RS-232 Port is configured as a DCE device. To communicate with a DTE device such as a computer, use a standard (or straight-through) RS-232 cable. To communicate with a DCE device, use either a null modem adapter in line with a standard RS-232 cable, or a null-modem serial cable.

You can make your own cables by following the pin configuration in the chart below. To do so, you must determine if your host RS-232 device is 9-pin or 25-pin, and whether it is configured as a DCE or DTE device.

With the Dolphin 7200 HomeBase, use the appropriate cable to connect each device to the Main Comm Port for a single Dolphin HomeBase or to the Multi-HomeBase Port if you are creating a Dolphin HomeBase network.

Connect the power supply to the Dolphin HomeBase. Plug the AC transformer into the Dolphin HomeBase 12 Volt DC power supply connector. The AC wall transformer provided can power only one Dolphin HomeBase.

Hand Held Products recommends that you leave the Dolphin HomeBase connected to its power source at all times, so that it is always ready to use.

Setting the Configuration Switches

Use these switches to select the network and communications modes for your Dolphin HomeBase. If you are configuring the HomeBase for a single Dolphin Terminal, the switch must be in the ‘Single’ position for proper basic operation. The switch must be set to ‘Multi’ for proper network operation if you are creating a HomeBase network. The configuration switch must be in the program position to change the baud rate.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

Setting the Baud Rate

You may use the HomeBase Configuration utility program to select the baud rate. The program can also be used to change the host system’s COM port and will run a diagnostic check for optimal communications. After changing the baud rate, you must power the HomeBase off and then on again. The program is one of the utility programs that come with the Dolphin OS and Development System. For more on HomeBase Configuration, see the chapter 9.

Modes of Operation

Through the Command Mode, the host application software provides command instructions for configuring a single Dolphin HomeBase or a network of HomeBases for communications. Once configured, the HomeBase(s) is in Transparent Mode and ready for communications.

Command Mode

You can configure a single Dolphin HomeBase or a whole network and select units for communications via the host application by entering the Command Mode. Data transmission is not possible while the Dolphin HomeBase network is in this mode. Go into Command Mode by entering an escape sequence that informs the HomeBase network that it will be receiving commands from the host device or application. The escape string is:

<ESC>HHP [>100ms<1s] Next Command

where <ESC> is an ASCII 27 character. The escape string should be followed by a >100ms<1second period of line silence. When sending commands, the escape string must precede the command string. The HomeBase automatically exits Command Mode after receiving each command.

Programming commands used for configuring single Dolphin HomeBases include Version Number and Baud Rate Selection. You configure HomeBase networks using the Baud Rate Selection, Address Assignment and Device Selection programming commands. See the sections on Configuring A Single Dolphin HomeBase and Creating a HomeBase Network for details.

Transparent Mode

When the Dolphin HomeBase is selected by the host application and ready for communications, it is in Transparent Mode. In this mode, the HomeBase facilitates point-to-point communication between the host device and the Dolphin Terminal. Data sent through the RS-232 link is passed directly to and from the Dolphin Terminal via the Infrared Link between the terminal and the HomeBase.

NOTE

The configuration

switches are checked at

power up. Changes in the

switch settings will not be

recognized until power is

turned off and

then back on.

NOTE

The baud rate is stored

in Non-Volatile Memory

and is retained even if

the power is removed

from the network.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

Configuring a Single Dolphin 7200 HomeBase

To prepare a single Dolphin HomeBase for communications, you must enter the Command Mode to configure the version number and select the baud rate.

Version Number

To retrieve the version number for the Dolphin HomeBase:

1. Enter or send the escape and command strings:

<ESC>HHP >100ms< 1s V

This command will return the version number but is not needed for communications.

Baud Rate Selection

The Dolphin HomeBase baud rate is set to 57600 at the factory. Use the configuration switches on the HomeBase’s back panel to select the network and communications modes for your Dolphin. The following table outlines the configuration switch settings:

Switch Setting Function

1 SINGLE (UP) Single HomeBase only

2 FIXED BPS

Baud rate fixed at 9600

(DOWN)

2 PROGRAM (UP) Baud rate can be programmed

Figure 17 Configuration Switch Settings on HomeBase for Single HomeBase

To ensure communications, leave Switch 2 in the ‘FIXED BPS’ position and configure your communications software for 9600 baud. When Switch 2 is in the ‘PROGRAM’ position, the baud rate can be changed using the following procedure or you may use the HomeBase Configuration Utility program.

1. Enter or send the escape and command strings:

<ESC>HHP >100ms< 1s B

where n is the ASCII number corresponding to the baud rate shown in the table below. For example, the string <ESC>HHPB6 (which consists of the escape string and the command B6) would set the baud rate for the network to 19200. No response will be transmitted back to the host after executing this function.

Creating a Dolphin 7200 HomeBase Network

This information applies only to the Dolphin 7200 HomeBase. The Dolphin 7200 Compact HomeBase is not networkable. Each HomeBase must have its own AC power adapter connected to a standard AC electrical socket. The group can be placed on a table or desk, or rail-mounted using the mounting holes on the two outside Dolphin HomeBase units.

How to Daisy Chain the Dolphin HomeBases

To form a HomeBase network, daisy chain the HomeBases together using one of the following methods:

• Align adjacent units so that the MULTI-HOMEBASE PORT of one unit

will mate with the MAIN COMM PORT of the next unit until all HomeBases in the network are connected.

• Use a RS-232 cable to connect the Multi-HomeBase Port on one terminal

to the MAIN COMM PORT on the next terminal. Repeat this step to include each additional terminal in the chain. Connect the last terminal to the host computer and leave the last MULTI-HOMEBASE PORT open if it is not needed.

Programming Commands

To configure a Dolphin HomeBase network, these attributes must be programmed: Address Assignment, Baud Rate Selection and Device Selection.

Address Assignment

Use the Address Assignment command to establish unit IDs for each Dolphin HomeBase in your network. This must be done before a unit can be selected for communications. To establish an Address Assignment:

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

1. Type or send the escape and command strings to set-up the configuration mode

and establish the beginning unit ID number:

NOTE

The configuration

switches are checked at power up. Changes in the switch settings will not be

recognized until power is

turned off and

back on.

<ESC>HHP >100 ms< C >100 ms< 1s I

n is the number representing the first unit in the network

For example, the string <ESC>HHPCI0 would instruct the network to set up ID

numbers for all the units in the network beginning at zero (0).

2. The first Dolphin HomeBase in the network receiving the command responds to

the host with:

<SYN>

<SYN> indicates that the command was accepted

3. In sequence, each Dolphin HomeBase will determine its own ID number by

adding one to the previous ID number.

4. When ID numbers are established for all HomeBases, the last HomeBase will

return this response to the host:

<ACK>n

<ACK> indicates completion of ID configuration; n represents the ID number

for the last unit in the network.

Programmer’s Note: When sending ID numbers to the Dolphin HomeBase, remember that numbers typed on the keyboard are ASCII numbers which will be converted to Hex when sent to the Dolphin HomeBase. For example, typing the command from the keyboard:

<ESC>HHP >100ms< C >100ms< 1s I1

would instruct the network to set up ID numbers for each Dolphin HomeBase starting with the ASCII number 1. The first unit in the network would actually receive the number 31 Hex (since ASCII 1 is equal to 31 Hex) as the starting ID number. Each unit in the network would sequentially add one to this starting ID number to establish its own ID. So, for a network of 15 units, the final ID number would be set up as 3F Hex. When the final unit sends back an <ACK>3F, the host computer (which converts Hex data back to ASCII) will then display the ID number as “?” instead of 15 as you might expect.

Baud Rate Selection

The Dolphin HomeBase baud rate is preset to 57600 at the factory. Use the configuration switches on the back panel of the HomeBase to select the network and communications modes for your Dolphin. The following table outlines the configuration switch settings:

When Switch 2 is in the ‘PROGRAM’ position, the baud rate can be changed using the following procedure or by using the HomeBase Configuration Utility.

Enter or send the escape and command strings:

<ESC>HHP >100ms< 1s Bn

n is the ASCII number corresponding to the baud rate shown in the table below. For example, the string <ESC>HHPB6 (which consists of the escape string and the command B6) would set the baud rate for the network to 19200. No response will be transmitted back to the host after executing this function.

Device Selection

Use this command to enable the host device to select a specific Dolphin HomeBase in the network for communication.

1. Enter or send the escape and command strings:

<ESC>HHP >100ms< 1s S

where n is the unit ID of the Dolphin HomeBase being selected

2. The Dolphin HomeBase with the unit ID corresponding to the ID number in the

Device Selection command string will respond with:

<ACK>n

to indicate to the host that it is present. n is the unit ID.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

When data transfer begins, the COMM LED on the Dolphin HomeBase will blink red and green. A unit remains selected until another unit in the network is selected. For example, the string <ESC>HHPS3 would select the unit with ID number 3 for communications. That unit would then send back an <ACK>3.

A selected unit in the Dolphin HomeBase network will assert the DSR signal of the HomeBase when a Dolphin terminal is present. The DSR signal can be used by the host application to determine if a Dolphin terminal is present and selected.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE

Communicating with the Dolphin Terminal

To communicate with the Dolphin and any other devices connected to the HomeBase:

1. Insert the Dolphin into the terminal well of the HomeBase. If the Dolphin is in

sleep mode, it will awaken into active state.

2. The CHARGING MAINBATT LED on the HomeBase will turn on. If the

Dolphin does not turn on, or the LED does not light up, make sure that it is properly seated in the terminal well and that the power supply is properly connected to the HomeBase and plugged into a functioning AC outlet.

3. Start your application on the Dolphin terminal or the host computer. Data can

then begin transmitting between the terminal and the devices connected to the Dolphin HomeBase.

When data transfer begins, the COMM LED on the Dolphin HomeBase will blink red and green. If the HomeBase will not communicate with the Dolphin, check the port connections to ensure that the HomeBase is correctly configured. See Chapter 10, Troubleshooting, for more information.

CHAPTER 8 USING THE DOLPHIN 7200 COMPACT HOMEBASE

Hub of the System

As the hub of your Dolphin system, the Dolphin 7200 Compact HomeBase performs three important functions – battery management, communications and storage.

Battery Management

The Dolphin 7200 Compact HomeBase uses a charging method that senses when the battery pack is fully charged and then drops to a trickle charge to keep the battery pack at full capacity. The battery pack does not need to be discharged before recharging because this method protects the battery from damage caused by overcharging.

The Dolphin 7200 Compact HomeBase provides power to the Dolphin terminal to enable the terminal to charge its battery.

IrDA Optical Communications

The IR communications port on the Compact HomeBase connects with the IrDA port on the Dolphin. Reliable data communications at speeds of up to 115 baud can be transmitted by the HomeBase. With no pins or contacts to break, IrDA will work reliably for years.

The Dolphin 7200 Compact HomeBase is not networkable.

Convenient Storage

The Dolphin 7200 Compact HomeBase is a safe and convenient storage receptacle for the Dolphin terminal.
