This section is designed to help you understand the basic structure and elements of ESP (Easy Setup Program).

When you open ESP, unless otherwise specified in the ESP Preferences dialog accessible from the Options heading on the menu toolbar, you will enter EZ Mode for initial setup. From there, you can enter Application Mode (App Mode) and access three configuration menus (Communications, Read Cycle, and Symbologies), a Terminal interface, and a

Utilities interface.

ESP can be used to configure the MS-2 CCD Reader in three main ways:

• Tree Controls: Each configuration menu contains a list of all option settings that pertain to that specific element of reader operation. For example, the Communications menu shows a Host Port Connections option, and then a list of the sub-options Baud Rate, Parity, Stop Bits, and Data Bits. Each of these sub-options is configurable by using dropdown menus.

• Graphic User Interfaces: Reader settings can be configured using such point-and-click tools as radio buttons, zoom in/zoom out sliders, spin boxes, check boxes, and drag-and-drop functions.

• Terminal: ESP’s Terminal allows you to send serial configuration and utility commands directly to the reader by typing them in the provided text field.

Information about using ESP in specific applications is provided in subsequent sections.

For ESP system requirements, see Minimum System Requirements in Quick Start.

Host Port Connections

The following settings define the basic transmission speeds and digital standards that ensure common formatting.

Baud Rate, Host Port

Usage: Can be used to transfer data faster or to match host port settings. Definition: The rate at which the reader and host transfer data back and forth. Serial Cmd: <K100,baud rate,parity,stop bits,data bits> Default: 9600 Options: 1 = 1200 2 = 2400 3 = 4800

4 = 9600 5 = 19.2K 6 = 38.4K

Parity, Host Port

Usage: Only changed if necessary to match host setting. Definition: An error detection routine in which one data bit per character is set to 1 or 0

so that the total number of bits in the data field is either even or odd.

Serial Cmd: <K100,baud rate,parity,stop bits,data bits> Default: Even Options: 0 = None 1 = Even 2 = Odd

Stop Bits, Host Port

Usage: Only changed if necessary to match host setting. Definition: One or two bits added to the end of each character to indicate the end of

the character.

Serial Cmd: <K100,baud rate,parity,stop bits,data bits> Default: One Options: 0 = One 1 = Two

Communications

Host Port Protocol

Usage: In general, the point-to-point protocols will work well in most applications.

They require no address and must use RS-232 or RS-422 communications standards.

Definition: Protocols define the sequence and format in which information is transferred

between the reader and the host.

Serial Cmd: <K140,protocol> Default: Point-to-Point Options: 0 = Point-to-Point

1 = Point-to-Point with RTS/CTS

Note: The preamble <K141> and postamble <K142> character strings can be used to frame the decoded data in both protocol modes.

Point-to-Point (Standard)

Usage: Used only with RS-232 or RS-422. Definition: Standard Point-to-Point requires no address and sends the data to the

host whenever it is available, without a request or handshake from the host.

Serial Cmd: <K140,0>

Point-to-Point with RTS/CTS

Usage: A reader initiates a data transfer with an RTS (request-to-send) transmission.

The host, when ready, responds with a CTS (clear-to-send) and the data is transmitted. RTS and CTS signals are transmitted over two dedicated wires as defined in the RS-232 standard. Used only with RS-232.

Definition: Point-to-Point with RTS/CTS (request-to-send/clear-to-send) is a simple

hardware handshake protocol that allows a reader to initiate data transfers to the host.

Serial Cmd: <K140,1>

MS-2 Read Cycle Overview

The MS-2 outputs symbol data as soon as it is decoded. There is no “End of Read Cycle” option. Multiple symbol operations are emulated by controlling the read cycle duration and the time allowed between identical consecutive decodes.

The following conditions also apply:

1. In Single symbol mode, a read cycle ends only on a decode, falling trigger, or timeout.

2. In Multiple symbol mode, the read cycle begins on a triggered event, but starts over after any symbol has been decoded.

3. There is no “new trigger” feature.

4. There is no timeout for External Level mode.

5. There is no Continuous Read 1 Output setting in Trigger Mode, but this setting can be emulated by following the steps described in

Continuous Read 1 Output Emulation

4-4 MS-2 CCD Reader User’s Manual

Read Cycle

Number of Symbols

Usage: Commonly used in shipping applications where an object contains individual

symbols for part number, quantity, and other values.

Definition: This feature allows one trigger event to decode all symbols present. Conditions: The following conditions apply:

• When Number of Symbols is set to Single, the read cycle ends when one symbol is decoded and output.

• When Number of Symbols is set to Multiple, all decoded symbol data (for both the same and different symbols) is output while the read cycle is active and/or no timeout has occurred.

• If set to Multiple and Time Between Identical Decodes is less than the decode time (typically about 4ms), the same symbol data can be output multiple times.

Number of Symbols

Definition: Number of Symbols is the number of different symbols that can be read in

a single read cycle.

Serial Cmd: <K222,number of symbols> Default: 1 Options: 0 = Multiple

1 = Single

MS-2 CCD Reader User’s Manual 4-5

Time Between Identical Decodes

Usage: Can be used to prevent repetition of data output. Also useful for emulating

Multiple symbol operations. When used in conjunction with Number of Symbols set to Multiple, Time Between Identical Decodes can be set so

that more than one symbol can be read within a read cycle.

Definition: Determines the length of time that the reader will wait before it outputs the

same symbol’s data a second time.

Serial Cmd: <K503,time between identical decodes> Default: 0 Options: 0 to 2550 ms

4-6 MS-2 CCD Reader User’s Manual

Read Cycle

Initiate Read Cycle:

Object #1, moving in front of the detector beam, causes a change in the trigger state, which initiates the read cycle.

End Read Cycle:

The same object, moving out of the detector beam, causes another change in the trigger state, which ends the read cycle.

Trigger Mode

Definition: The Trigger is the event that initiates a read cycle. Serial Cmd: <K200,trigger mode> Default: Continuous Read Options: 0 = Continuous Read

2 = External Level 3 = External Edge 4 = Serial Data 5 = Serial Data and Edge

Continuous Read

Usage: Continuous Read is useful in testing symbol readability or reader functions.

It is not recommended for normal operations.

Definition: In Continuous Read, trigger input options are disabled and the reader is

always in the read cycle. If a single symbol stays within read range for multiple read cycles, its data will be transmitted repeatedly until it leaves the read range.

The reader sends replies to serial commands that require responses when symbol data is transmitted.

Note: No Read

Serial Cmd: <K200,0>

options have no affect on

Continuous

Read.

External Level

Usage: This mode is effective in an application where the speeds of the conveying

apparatus are variable and the time the imager spends reading each object is not predictable. It also allows the user to determine if a No Read has occurred.

Definition: External Level allows the read cycle (active state) to begin when a trigger

(change of state) from an external sensing device is received. The read

Serial Cmd: <K200,2>

MS-2 CCD Reader User’s Manual 4-7

cycle persists until the object moves out of the sensor range and the active trigger state changes again.

Trigger Mode

Initiate Read Cycle:

Object # 1, moving in front of the detector beam, causes a change in the trigger state, which initiates the read cycle.

Initiate Second Read Cycle:

Object # 2, moving in front of the detector beam, causes another change in the trigger state. This signal initiates a new read cycle and ends the previous read cycle unless

Timeout

is enabled and a good read

or timeout has not occured.

External Edge

Usage: This mode is highly recommended in any application where conveying

speed is constant, or if spacing, object size, or read cycle timeouts are consistent.

Definition: External Edge, as with Level, allows the read cycle (active state) to begin

when a trigger (change of state) from an external sensing device is received. However, the passing of an object out of sensor range does not end the read cycle. The read cycle ends with a good read output, or, depending on the End of Read Cycle setting, a timeout or new trigger occurs.

Serial Cmd: <K200,3>

Serial Data

Usage: Serial Data is effective in a highly controlled environment where the host

knows precisely when the object is in the field of view. It is also useful in determining if a No Read has occurred.

Definition: In Serial Data, the reader accepts an ASCII character from the host or

controlling device as a trigger to start a read cycle. A Serial Data trigger behaves the same as an External Edge trigger.

Serial commands are entered inside angle brackets, as shown here: <t>.

Serial Cmd: <K200,4>

Note: In Serial Data, sending a non-delimited start serial character will start a read cycle; however, a non-delimited stop serial character has no effect.

Serial Data and Edge

Usage: Serial Data and Edge is seldom used but can be useful in an application

that primarily uses an external sensing device but occasionally needs to be triggered manually.

An auxiliary terminal can be connected to the auxiliary port so the user can send the serial trigger character through the reader to the host.

Definition: In this mode the reader accepts either a serial ASCII character or an external

trigger pulse to start the read cycle.

Serial Cmd: <K200,5>

Note: In Serial Data, sending a non-delimited start serial character will start a read cycle; however, a non-delimited stop serial character has no effect.

4-8 MS-2 CCD Reader User’s Manual

Read Cycle

Continuous Read 1 Output Emulation

Usage: Continuous Read 1 Output can be useful in applications where it is not

feasible to use a trigger and all succeeding symbols contain different information. It is also effective in applications where the objects are presented by hand.

The MS-2 does not offer this feature, but it can be emulated by following the steps described below.

Definition: In Continuous Read 1 Output Emulation, the trigger must be active

(grounded) for as long as the MS-2 needs to be scanning symbols. The MS-2 will only output symbol data once while that symbol remains in the MS-2’s field of view. If the symbol is removed and then presented again, it must be removed from the field of view for the amount of time specified in the Time Between Identical Decodes value before the MS-2 will decode the symbol again. However, if a new symbol is presented, the MS-2 will decode it and output symbol data immediately.

Setting Up Continuous Read 1 Output Emulation

1. Set Number of Symbols to Multiple.

Serial Cmd: <K222,0>

2. Set Time Between Identical Decodes to 500 (ms).

Serial Cmd: <K503,500>

3. Set Trigger Mode to External Level.

Serial Cmd: <K200,2>

Important: Continuous Read 1 Output Emulation is not recommended for automated environments, because there is typically no reliable way to verify whether or not a symbol was missed.

MS-2 CCD Reader User’s Manual 4-9

Serial Trigger Character (Delimited)

Usage: Allows the user to define the trigger character and delimiters that start

and stop the read cycle.

Definition: A serial trigger is considered an online host command and requires the

same command format as all host commands. It must be entered within angle bracket delimiters < > or, in the case of non-delimited triggers, it must define individual start and stop characters.

Serial Cmd: <K201,serial trigger character> Default: ^] (<GS>) Options: Any single ASCII character, including control characters, except NUL (00 in

hex), an existing host command character, or an on-line protocol character. Control characters entered on the command line are displayed in the menu as mnemonic characters.

Note: Serial Data or Serial Data and Edge triggering mode must be enabled for Serial Trigger Character to take effect.

4-10 MS-2 CCD Reader User’s Manual

Read Cycle

Start Trigger Character (Non-Delimited)

Usage: Useful in applications where different characters are required to start a

read cycle.

Definition: A single ASCII host serial trigger character that starts the read cycle and is

not enclosed by delimiters such as < and >. Non-delimited Start characters can be defined and will function according

to the trigger event. When defining Start trigger characters, the following rules apply:

•In External Edge the reader looks only for the Start trigger character and ignores any Stop trigger character that may be defined.

•In External Level the Start trigger character begins the read cycle and the Stop trigger character ends it. Note that even after a symbol has been decoded and the symbol data transmitted, the reader remains in External Level trigger read cycle until a Stop character is received.

•In Serial Data and Edge trigger mode, either a Start trigger character or a hardware trigger can start an edge trigger read cycle.

Serial Cmd: <K229,start trigger character> Default: NUL (00 in hex) (disabled) Options: Two hex digits representing any ASCII character except XON and XOFF.

MS-2 CCD Reader User’s Manual 4-11

Stop Trigger Character (Non-Delimited)

Usage: Useful in applications where different characters are required to end a

read cycle.

Definition: A single ASCII host serial trigger character that ends the read cycle and is

not enclosed by delimiters such as < and >. Non-delimited Stop characters can be defined and will function according

to the trigger event. When defining Stop trigger characters, the following rules apply:

•In External Edge the reader looks only for the Start trigger character and ignores any Stop trigger character that may be defined.

•In Serial Data and Edge trigger mode, either a Start trigger character or a hardware trigger can start an edge trigger read cycle.

Serial Cmd: <K230,stop trigger character> Default: NUL (00 in hex) (disabled) Options: Two hex digits representing any ASCII character except XON and XOFF.

4-12 MS-2 CCD Reader User’s Manual

Read Cycle

No Decode Timeout

Usage: Useful in tightly-controlled applications that require a read cycle to end

before the next object appears.

Definition: The duration of the read cycle as measured from either the beginning of the

read cycle or from the last decode.

Serial Cmd: <K220,0,seconds>

Note: The first parameter is always a zero (0) and does not change.

Default: 2 Options: 1 - 4095

The MS-2 times out if no symbol is decoded during the No Decode Timeout period. If a symbol is decoded before the timeout expires, the timeout period starts again.

No Decode Timeout only applies to Edge, Serial Data, and Serial Data and Edge trigger modes.

In Single symbol mode (<K222,1>), No Decode Timeout is the maximum amount of time the reader will attempt to decode after a trigger is activated.

In Multiple symbol mode (<K222,0>), No Decode Timeout is the time in which there are no decodes—not the time since the trigger was activated. That is, if the reader continues to decode symbols presented to it, it will not exit the read cycle unless the time between decodes exceeds the time set in No Decode Timeout.

For Level trigger mode, the read cycle ends when the trigger falls, or when a symbol is decoded and output in Single symbol mode.

MS-2 CCD Reader User’s Manual 4-13

Decodes Before Output

Note: When setting up, determine if the reader’s scan rate is capable of scanning your

longest symbol the required number of times.

Usage: Useful for increasing the reliability of decodes for symbologies that do not

have internal error checking.

Definition: The number of decodes required per symbol before its data is sent.

Requires the reader to decode a symbol successfully a designated number of times before data is output.

Serial Cmd: <K221,decodes before output> Default: 0 Options: 0 to 10 (0 = “Auto-adaptive”)

Note: If the reader is in Single symbol mode and it doesn’t achieve the number of required decodes during the read cycle, a No Read message will be output.

Note: Higher Decodes Before Output settings will decrease the throughput rate.

4-14 MS-2 CCD Reader User’s Manual

Read Cycle

No Read Message

Note: A No Read message can only be transmitted when in Single symbol mode and no

decodes occur.

Usage: Used in applications where the host needs serial verification that a symbol

has not been read.

Definition: When enabled, and if no symbol has been decoded before timeout or the

end of the read cycle, the No Read message will be transmitted to the host.

No Read Status

Serial Cmd: <K714,status,No Read message> Default: Enabled Options: 0 = Disabled 1 = Enabled

No Read Message

Definition: Any combination of ASCII characters can be defined as the No Read

message.

Serial Cmd: <K714,status,No Read message> Default: No Read Options: 1 to 20 ASCII characters.

Note: A No Read

Shutter Speed

Shutter Speed allows shutter speed to be controlled automatically, set to a specific value,

or defined within a fixed range. Important: Shutter Speed settings should not be changed unless they are being

increased to accomodate a fast line speed in a dynamic application.

Usage: Faster shutter speeds may be necessary in faster-moving applications.

Slower shutter speeds are useful in slower, lower-contrast applications.

Definition: Shutter speed is the amount of time that the sensor is exposed to light. Serial Cmd: <K544,shutter speed> Default: Automatic Options: 0 = Automatic

1 = Slow 2 = Medium 3 = Fast

Beeper

The programmable Beeper can be set to indicate a Good Read or a No Read.

Definition: A sustained tone that can be programmed to indicate a Good Read or a No

Read. Also beeps in response to a <Z> command, a <Zrd> command, a firmware download, a parameter default, or a hardware default.

Serial Cmd: <K702,beeper mode> Default: On Good Read Options: 0 = Disabled

1 = On Good Read

2 = On No Read

Full ASCII Set (Code 39)

Usage: Must be enabled when reading characters outside the standard character

set (0-9, A-Z, etc.) The user must know in advance whether or not to use the Full ASCII Set

option. Since Full ASCII Set requires two code words to encode one character, it is less efficient.

Definition: Standard Code 39 encodes 43 characters; zero through nine, capital “A”

Utility commands are generally commands that are performed during reader operations to perform miscellaneous operations on reader hardware. Serial utility commands are not prefaced with a ”K” and a numeric value, nor do they require an initialization command (<A> and <Z>). They can be entered from ESP’s Terminal or Utilities views.

Read Rate

Read Rate Commands

Enter Decodes / Second Test

Sending <C> instructs the imager to transmit the decodes per second and symbol data (if any). The decode rate can vary dramatically due to the angle and location of the symbol in relation to the field of view. This test is very useful in aligning and positioning the imager during setup.

Enter Decode Percent Test

Sending <Cp> instructs the imager to transmit the percentage of decodes and any decoded symbol data.

End Decodes / Second and Decode Percent Tests

Sending <J> ends both the Percent test and the Decodes/Second test.

Read Rate Process

The read rate process is expected to operate very similar to a normal read cycle. The differences are:

•The K222 “number of symbols” parameter does not take effect. Every unique decode is recorded and output at the end of a read rate test cycle.

•The K221 “good decodes to read” parameter does not take effect. Only one decode is required to be recorded and output.

• System time is recorded at the beginning and end of the test, and an exact number of scan frames are captured and processed.

Firmware

Firmware Update

Firmware Update is used to download application code to the reader. Application code versions are specific to your reader. Consult with your sales representative before downloading application code. If needed, application code will be sent to you.

To download application code:

1. Be sure that the reader is connected to the host computer.

2. Apply power to the reader.

3. In the Firmware Update dropdown menu, select App Code and then click the Start button. This will open a dialog that allows you to browse for the application code file.

4. Navigate to where the application code file is located on your host computer and select the file.

5. Allow approximately a minute for firmware to download. As the application code begins to download, the reader will be silent, the LEDs will

flash intermittently, and a progress indicator at the bottom of the ESP window will show when the download is complete.

6. Verify that application code has been updated.

Caution: Do not interrupt power or disconnect the host cable while download is in progress.

Firmware Verification

ESP allows you to send a request to the MS-2 for the application code part number.

1. Click the Firmware tab.

2. From the dropdown menu to the left of the Request Part No. button, select App Code.

3. The application code part number will be displayed in the text field to the right of the Request Part No. button.
