Communications

Host Port Protocol

Usage:

Definition:

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.

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:

Definition:

Used only with RS-232 or RS-422.

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:

Definition:

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.

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

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


Read Cycle

Number of Symbols

Usage:

Commonly used in shipping applications where an object contains individual symbols for part number, quantity, and other values.

This feature allows one trigger event to decode all symbols present.

Definition:

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


4-5

Time Between Identical Decodes

Time Between Identical Decodes

Usage:

Definition:

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.

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 2550ms

4-6


Read Cycle

Trigger Mode

Definition:

The Trigger is the event that initiates a read cycle.

Serial Cmd:

<

K200,trigger mode

>

Default:

Options:

Continuous Read

0 = Continuous Read

2 = External Level

3 = External Edge

4 = Serial Data

5 = Serial Data and Edge

Continuous Read

Usage:

Definition:

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

It is not recommended for normal operations.

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 options have no affect on Continuous Read.

Serial Cmd:

<

K200,0

>

External Level

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.

Usage:

Definition:

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.

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

Serial Cmd:

<

K200,2

>


4-7

Trigger Mode

External Edge

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.

Usage:

Definition:

This mode is highly recommended in any application where conveying speed is constant, or if spacing, object size, or read cycle timeouts are consistent.

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:

Definition:

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.

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


Read Cycle

Continuous Read 1 Output Emulation

Usage:

Definition:

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.

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.


4-9

Serial Trigger Character (Delimited)

Serial Trigger Character (Delimited)

Usage:

Definition:

Allows the user to define the trigger character and delimiters that start and stop the read cycle.

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


Read Cycle

Start Trigger Character (Non-Delimited)

Usage:

Definition:

Useful in applications where different characters are required to start a read cycle.

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.


4-11

Stop Trigger Character (Non-Delimited)

Stop Trigger Character (Non-Delimited)

Usage:

Definition:

Useful in applications where different characters are required to end a read cycle.

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 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:

<

K230,stop trigger character

>

Default:

NUL

(00 in hex) (disabled)

Options:

Two hex digits representing any ASCII character except XON and XOFF.

4-12


Read Cycle

No Decode Timeout

Usage:

Definition:

Useful in tightly-controlled applications that require a read cycle to end before the next object appears.

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:

Options:

2

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.


4-13

Decodes Before Output

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:

Definition:

Serial Cmd:

Default:

Options:

Useful for increasing the reliability of decodes for symbologies that do not have internal error checking.

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.

<

K221,decodes before output

>

0

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


Read Cycle

No Read Message

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

Usage:

Definition:

Used in applications where the host needs serial verification that a symbol has not been read.

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 message is not output when the reader is disabled (when an



command has been sent).

Symbologies

Minimum Symbol Length (Code 39)

Usage:

Definition:

Minimum Symbol Length helps prevent truncations and increases data integrity by ensuring that only one symbol length will be accepted.

Specifies the exact number of characters that the reader will recognize (this does not include start and stop characters and check characters). The reader ignores any symbology that is less than the specified length.

Usage:

Default:

Options:

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” through capital “Z”, minus symbol, plus symbol, forward slash, space, decimal point, dollar sign, and percent symbol. When Full ASCII Set is enabled, the reader can read the full ASCII character set, from 0 to 255.

Interleaved 2 of 5

Interleaved 2 of 5

Usage:

Definition:

Interleaved 2 of 5 has been popular because it is the most dense symbology for printing numeric characters less than 10 characters in length; however,

Microscan does not recommend this symbology for any new applications because of inherent problems such as truncation.

A dense, contimuous, self-checking, numeric symbology. Characters are paired together so that each character has five elements, two wide and three narrow, representing numbers 0 through 9, with the bars representing the first character and the interleaved spaces representing the second character. (A check character is highly recommended).

Appendices

Serial Command Format

Serial commands are of two types: utility and configuration.

Rules that apply to both Utility and Configuration commands

• A less than

<

and greater than

>

character enclose the commands.

• Commands and data are “case-sensitive.” That is, characters must be entered as upper or lower case, as specified.


These are sent during operations and are not followed by

<A>

or

<Z>

.

Serial Configuration “K” Commands

These begin with a single “K” character followed by a 3-digit numeric value, data fields, and an initializing command, as follows:

<

K

numeric value,data,data,...etc.><initializing command>

An initializing command

<A>

or

<Z>

may follow the command. A

<Z>

initializes the reader’s memory and saves for power-on; an

<A>

initializes the reader’s memory but does not save for power-on.

For example, to enable UPC and save the change for power-on, send

<K473,1><Z>

.

To change Baud Rate to 4800 and reset without saving changes for power-on, send

<K100,3><A>

.

Serial Configuration Command Conventions

• All data fields (except the last) must be followed by a comma without a space.

• Typically,

NUL

cannot be used. The characters

<

,

>

, and

,

can be used, but only if entered as hex pairs.

• All fields preceding a modified field must be included unless there is no change in the preceding fields.

• If there is no change in preceding fields, then commas alone can be entered in these fields. For example, if only the last field in the command

<K100,4,1,0,1>

is changing, it can be entered as

<K100,,,,1>

.

• All fields following a modified field can be omitted. For example, to change Baud Rate to

4800 without changing the other host port paramters, send

<K100,3>

.

Concatenating Configuration Commands

Commands can be concatenated (added together) in a single string.

For example,

<K100,4><K222,1><K470,0><A>

sets the Baud Rate to 9600, enables

Multiple symbol mode, disables Code 39, and resets the data buffers (without saving the changes for power-on).


A-7

Serial Configuration Commands

Configuration Command Status Request

To learn the reader’s current configuration, send the Configuration Command Status command:

<K?>

.

Entering Control Characters in Serial Commands

To enter control characters within a serial command, hold down the Ctrl key while typing the desired character.

Example: To enter a carriage return and line feed (

^M^J

), enter

<K141,1,CTRL-m CTRL-j>

.

Cleaning

The MS-2 CCD Reader has a hard-coated window that should only be cleaned with alcohol

(100% isopropyl).

Mounting

When mounting the MS-2 CCD Reader, do not insulate the stand mount. The bottom panel is the hottest part of the reader and metal-to-metal contact is necessary for heat dissipation.


A-11

Using an External Trigger

Appendix G — Using an External Trigger

Two types of inputs are used on Microscan readers. 5 volt devices have NPN trigger inputs. 10-28 volt devices have optoisolated inputs and outputs.

5 Volt Devices

To trigger a 5 volt device, the input has to be pulled down to “signal ground” (NPN). This can be done by relays or by a transistor-sourced signal. If a 5 volt device is used in combination with an IC-332, it must be connected as a 10-28 volt device.

Reader

Reader Sensor

Sensor

10-28 Volt Devices

To trigger a 10-28 volt device, a small amount of current needs to flow from “Trigger +” to

“Trigger –”. If a PNP source is used, “Trigger –” must be connected to “signal ground”. If an

NPN source is used, “Trigger +” must be connected to the supply voltage.

Host — A computer, PLC, or other device that is used to execute commands and process data and discrete signals.

Image Sensor — A device that converts a visual image to an electrical signal; a CCD, for example.

Initialize — Implement serial configuration commands into the reader’s active memory.

Input — A channel or communications line. Decoded data or a discrete signal that is received by a device.

Ladder Orientation — A linear symbol orientation in which the bars are parallel to the symbol’s direction of travel.

Light-Emitting Diode (LED) — A semiconductor device that emits light when conducting current.

Lens — A transparent piece of material with curved surfaces which either converge or diverge light rays.

Multidrop — A communications protocol for networking two or more readers or other devices with a concentrator (or controller) and characterized by the use of individual device addresses and the RS-485 standard.

Normally Closed — A discrete output state that is only active when open.

Normally Open — A discrete output state that is only active when closed.

Object Plane — An imaginary plane in the field of view, focused by a reader’s optical system at the corresponding image plane on the sensor.

Output — A channel or communications line. Data or discrete signals that are transmitted or displayed by a device.

Parity — An error detection routine in which one data bit in each character is set to 1 or 0 so that the total number of 1 bits in the data field is even or odd.

Picket Fence Orientation — A linear symbol orientation in which the bars are perpendicular to the symbol’s direction of travel.

Pitch — Rotation of a linear or 2D symbol around an axis parallel to the symbol length on the substrate. See the illustration below.

Glossary of Terms

PLC — See Programmable Logic Controller.

Port — Logical circuit for data entry and exit. (One or more ports may be included within a single connector.)

Programmable Logic Controller (PLC) — An electronic device used in industrial automation environments such as factory assembly lines and automotive manufacturing facilities.

Protocol — The rules for communication between devices, providing a means to control the orderly flow of information between linked devices.

Random Access Memory (RAM) — A data storage system used in computers, composed of integrated circuits that allow access to stored data in any sequence without movement of physical parts.

Read Cycle — A programmed period of time or condition during which a reader will accept symbol input.

Read-Only Memory (ROM) — A data storage medium used in computers and other electronics, primarily used to distribute firmware.

Skew — Rotation of a linear or 2D symbol around an axis parallel to the symbol height on the substrate. See the illustration under the definition of Pitch.

Substrate — The surface upon which a symbol is printed, stamped, or etched.

Symbol Transitions — The transition of bars and spaces on a symbol, used to detect the presence of a symbol on an object.

Symbology — A symbol type, such as Code 39 or Code 128, with special rules to define the widths and positions of bars and spaces to represent specific numeric or alphanumeric information.

Tilt — Rotation of a linear or 2D symbol around an axis perpendicular to the substrate.

See the illustration under the definition of Pitch.

Trigger — A signal, transition, or character string that initiates a read cycle.

Very Large-Scale Integration (VLSI) — The creation of integrated circuits by combining thousands of transistor-based circuits on a single chip.

VLSI — See Very Large-Scale Integration.
