2. Allow some time for the scanner to cycle through the focus, gain, and tracking settings. Do not move or disturb the scanner or test symbol while calibration is in progress.

3. When calibration is complete, the settings that provided the highest read rate will be selected. You will see one of the following messages: Calibration Passed, Calibration

Failed, or Original Settings Were Optimal.

Note: To silence the beeper, interrupt scanning by removing or blocking the test

symbol, or send a <K702,0> command to disable the beeper.

If calibration fails, try the following:

1. Check the read range for your particular symbol density.

2. Examine symbol quality and try a different sample symbol.

3. Slightly skew or tilt the symbol or scanner to minimize specular reflection.

4. Verify that the correct symbology is enabled.

MS-890 Industrial Automation Scanner User Manual

Page 23

Quick Start

Step 9 — Test Read Rate

Important: To receive symbol data through the 9-pin configuration port, you must enable the port with the following command: <K146,,1>.

1. Position the symbol in front of an operational MS-890 scanner.

2. Click the Utilities button.

3. Click the Start button in the Read Rate view.

If calibration has passed, the scanner sends data to the host computer and emits a beep (if the beeper is enabled) for each good read.

Move your symbol toward the scanner and away from the scanner until the decode rates drop off in each direction. This will give you a sense of the depth of field (inner and outer ranges) for your symbol’s density and range.

Note:

If the scanner is in the default routine, it will read and beep repeatedly as long as a readable symbol remains in the read range and the read cycle configuration has not changed.

• To end the read rate test, right click Read Rate and select the Stop button.

Communications

RS-232/422 Host Port

Includes host port connections and host protocols.

Communications Options

You can communicate with the scanner through the following ports:

• 9-pin D-sub external connector

• Wiring box

• 25-pin D-sub external connector

Only one port can be used at a time to receive commands.

Communications with Host through the 9-pin Host Port

For the 9-pin configuration port, set the host communications settings as follows: 57.6K baud, 8 data bits, 1 stop bits, and None parity. See Chapter 1, Quick Start, for more information on using the 9-pin port.

Note: The 9-pin configuration port settings are not changeable.

Communications with Host through the 25-pin Port

The default 25-pin host port configuration settings are as follows: 9600, 7, 1, and Even. Making changes to these communications parameters without corresponding changes in

linked device(s) can result in the loss of menu access. If this should occur, connect via the 9-pin port and reset your scanner’s host parameters to match the 25-pin defaults.

Communications with Host through the Wiring Box

The settings are the same as those of the 25-pin port. See Chapter 14, Wiring Box, for details on wiring connections.

MS-890 Industrial Automation Scanner User Manual

Communications

Host Protocol

Usage: In general, point-to-point protocols 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 scanner and the host, or in the case of Polling Mode, between scanners and a concentrator.

Important: When using Polling Mode, LRC must be Enabled and Preamble/ Postamble must be Disabled.

Serial Cmd: <K140,protocol,address>

Default: Point-to-Point Options: 0 = Point-to-Point

1 = Point-to-Point with RTS/CTS 2 = Point-to-Point with XON/XOFF 3 = Point-to-Point with RTS/CTS and XON/XOFF 4 = ACK/NAK 5 = Polling Mode

Point-to-Point (Standard)

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

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

Serial Cmd: <K140,0>

Point-to-Point with RTS/CTS

Usage:

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

Serial Cmd: <K140,1>

A scanner 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. CTS and RTS signals are transmitted over two dedicated wires as defined in the RS-232 standard.

Used only with RS-232.

These parameters take effect for RS-422 ports (not on the Auxiliary Port), and are completely independent of the

Polling Mode Options <K148>

The scanner always follows the protocol in both directions (to and from the host). There is no option to disable it from either direction.

NAK: (Negative Acknowledge) 0x15

The following are general outlines of the ACK/NAK protocol. Items that are framed by brackets ( [ ] ) can either be disabled or enabled. LRC does not include STX, but it does include preamble, postamble, and ETX.

Symbol Data Output

TX to host: [STX] [preamble] SYMBOL DATA [postamble] [ETX] [LRC] Response from host: ACK/NAK. Sent when LRC, ETX, postamble, or timeout (waiting

for more data) are detected (if REQ is disabled) depending on what is enabled.

Commands from Host to Scanner

TX to Scanner: [STX] <command> [ETX] [LRC] Response from Scanner: ACK/NAK. Sent when LRC, ETX, or command-ending angle

bracket ‘>’ are received, depending on what is enabled.

Command Response from Scanner to Host

TX to host: [STX] [preamble] COMMAND RESPONSE DATA [postamble] [ETX] [LRC] Response from host: ACK/NAK. Sent when LRC, ETX, postamble, command-ending

angle bracket ‘>’, or timeout (waiting for more data) are detected, depending on what is enabled.

As with Polling Mode <K140,5>, the scanner can optionally perform the REQ and RES event sequences in ACK/NAK mode. If the sender does not receive an ACK or NAK, it will send REQ to request such a response (if enabled). When the sender receives an ACK, too many NAKs, or times out (if already enabled), it will send a RES (if enabled) to terminate the transaction.

Auxiliary Port Protocol

Note: The Aux Port cannot be used when the host port is set to RS-422 or Multidrop.

As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical with those of the auxiliary device.

Usage: These commands set the communication parameters with the auxiliary port

which can be used to configure menus, send data to the host, display data transmissions originating from the host of the scanner, and relay data from other scanners set in tandem (Daisy-Chained). If the scanner’s host port needs to be dedicated to the host, but configuration must be done on the fly, the auxiliary port can be set to accept configuration changes by Command Processing.

Definition:

An auxiliary port connects the scanner to a remote display or to other scanners that can display or transfer data. As with the host port parameters, the auxiliary terminal’s settings (baud rate, parity, stop bits, and data bits) must be identical to those of the auxiliary device.

Aux Port Mode

Note: The Aux Port interacts only with the host port via the 25-pin port except when in Daisy Chain mode. When in Daisy Chain mode, the Aux Port will also interact with the

configuration port (9-pin port) or the wiring box network ports.

Definition: Determines the flow of data between the auxiliary port device(s), the scanner,

and the host. <

Usage:

Often used in conjunction with handheld scanners. Employs an auxiliary readout to detect mis-applied symbols.

Definition: In Transparent mode data is passed between the auxiliary port and the host.

The scanner buffers data from the auxiliary port and echoes the keyed data on the auxiliary port.

Data Initiated from the Auxiliary Port

Auxiliary port data is passed through to the host whenever a return key is pressed at the auxiliary port or symbol data is sent.

Whenever Aux Port data is sent with symbol data, the Aux Port data will appear between the preamble and the symbol data.

Auxiliary port data to the host is always sent with a preamble and a postamble.

If the scanner is in a polled mode to the host, auxiliary port data will still pass through.

Daisy Chain (Aux Port Mode)

Note: See also Daisy Chain Autoconfigure on page 3-19.

Usage: Used in applications where:

A symbol might be scanned in both ladder and picket fence directions. A symbol may be present on multiple sides of a package. Symbols are presented at different depths.

Definition: In a daisy chain application, scanners are connected in series or “daisy chain”

and decoded data is relayed from one scanner to another on up to the host. A master scanner has its host port linked to the host computer and its auxiliary

port linked to the host port of the first secondary scanner in the chain. Thereafter, each secondary’s auxiliary port is linked to the host port of the secondary that is further from the host in the daisy chain.

Each scanner in the daisy chain can be assigned an ID that accompanies any data that it sends.

Serial Cmd:

K101,aux port mode

daisy chain ID>

4 = Daisy Chain

Function: Before the master scanner times out, it checks its auxiliary port for data. It

should be set to wait at least 20 ms for each secondary in the daisy chain. (See Read Cycle Timeout on page 4-16.) If no data is received within the read cycle timeout, the master sends a No Read message to the host. Otherwise the complete data is sent.

If for example the master scanner is set to timeout in 120 ms, the first secondary scanner downstream might be set to 100 ms, the next to 80 ms, and so forth, thus assuring that at least 20 ms elapses between transmissions.

Daisy-chained scanners can send a series of symbols by enabling and a common multisymbol separator. If the master scanner does not receive the expected number of symbols, No Read messages are appended to the data string to make up the difference between the number of symbols enabled in Multisymbol and the number of symbols read.

For example, a master and two secondary scanners have set to 3 and Multisymbol Separator defined as %. If the master and the first secondary scanner do not find symbols, but the next secondary scanner registers a good read, the transmitted results would be:

,baud rate,parity,stop bits,data bits,daisy chain ID status,

Daisy Chain Autoconfigure

Note: This command is not available in ESP.

Usage: For quick setup and configuration of the daisy chain network. Definition: Daisy Chain Autoconfigure is issued to the master scanner in the daisy

chain and the software responds as follows:

• Counts the number of secondary scanners in the daisy chain.

• Assigns an internal ID number (1...n) to each secondary scanner, where the first secondary scanner is number 1 (and its own ID being a 0).

• Propagates the communications settings and the relevant operating modes of the master scanner to the host and auxiliary ports of each secondary scanner.

• Resets each secondary scanner.

• Verifies that each secondary scanner has acquired the new settings.

Serial Cmd: <K150DAISY>

When setting up a daisy chain operation, follow these steps:

1. Set the master (the scanner connected to the host) scanner to Serial. This sets all the scanners in the daisy chain to

Serial

when the command is carried out.

Before Autoconfigure you must set the primary scanner to Serial (S):

2. Send <K150DAISY> command.

3. If necessary, set the master scanner to Edge. After Autoconfigure you may set the primary scanner to Edge (S), but the other

scanners must remain in Serial (S):

After you’ve established communications and completed basic read rate testing, you will need to address the spatial and timing parameters associated with your application. In a typical operation, a bar-coded item moves along a line past a scanner. A trigger or timer activates a read cycle during which the scanner actively searches for symbols. You will need to decide how to initiate the read cycle and how and when to end it.

Note: When assigning characters in user-defined fields, the characters NUL, <, >, and , can only be entered through embedded menus, not through ESP or serial commands.

Note: You can learn the current setting of any parameter by inserting a question mark after the number, as in <K100?>. To see all K commands, send <K?>.

Note on Serial Commands: To preserve continuity with other Microscan products, some serial configuration commands may include 0s or 1s as placeholders. In order for a these commands to be implemented, the parameter values or a comma must be included.

Read Cycle

Multisymbol

Usage: Multisymbol is commonly used in shipping applications where a shipping

symbol contains individual symbols for part number, quantity, etc. This feature allows one trigger to pick up all the symbols. AIAG and EAN-128 are two application standards that address this need.

Definition: Multisymbol allows the user to define up to 12 symbols that can be read in a

single read cycle.

Conditions: The following conditions apply:

1. Each symbol must be different to be read unless they appear in the scan line at the same time.

2. The maximum number of characters in a read cycle is 32520 for all symbols.

The maximum number of characters the scanner can transmit is calculated by: Preamble + maximum number of symbols * (aux id + symbology id + maximum symbol length + quality output + ((number of insertion cells x cell length)+ separator) + postamble + LRC = 37425.

4. All No Read messages are posted at the end of the data string.

Continuous Read 1 Output

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 hand-presented.

Definition: In Continuous Read 1 Output the scanner self-triggers whenever it decodes

a new symbol or a timeout occurs. If End Of Read Cycle is set to Timeout and the symbol doesn't change, the

scanner will repeat the output at the end of each timeout period. For example,

Timeout

is set to one second, the scanner sends the symbol data immediately

and repeats the output at intervals of one second for as long as the symbol continues to be scanned.

If End Of Read Cycle is set to New Trigger, the scanner will send the current symbol data immediately, but send it only once. A new symbol appearing in the scanner’s range will be read and sent immediately provided it is not identical to the previous symbol read.

Serial Cmd: <K200,1>

Caution: In automated environments, Continuous Read 1 Output is not recommended because there is no one to verify that a symbol was missed.

Note: If Trigger is set to Continuous Read 1 Output, Number of Symbols will default back to 1 (if set to any number greater than 1).

Read Cycle

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

apparatus are variable and the time the scanner spends scanning 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 to begin when a trigger (change of

state) from an external sensing device is received. The read cycle endures until the object moves out of the sensor range and the active trigger state

changes again. Serial Cmd: <K200,2> Important: Level and Edge apply to the active logic state (Open or Closed) that exists

while the object is in a read cycle, between the rising edge and falling edge. Rising edge is the trigger signal associated with the appearance of an object. Falling edge is the trigger signal associated with the subsequent disappearance of the object.

Note: In External Trigger Level, sending a non-delimited start serial character will start a read cycle and sending a non-delimited stop serial character will end it. See

Serial Data

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

knows precisely when the object is in the scan zone. It is also useful in determining if a No Read has occurred.

Definition: In Serial Data, the scanner 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 Data and External Edge

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

applicatio needs to be manually triggered. An auxiliary terminal can be connected to the Aux Port so the user can send the serial trigger character through the scanner to the host.

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

trigger pulse to start the read cycle.

Trigger Filter Duration

Usage: Trigger Filter Duration is useful where trigger bounce could cause false

triggers. Definition: Trigger Filter Duration can prevent trigger bounce from falsely triggering the

scanner by limiting the time in which trigger pulses can be received.

Serial Cmd: <K200,trigger mode,trigger filter duration> Default: 320 (10 ms) Options: 0 to 65535 (0 to 2.047s in 31.25µs steps)

External Trigger State

Note: External Level, External Edge, or Serial Data and External Edge trigger mode must be enabled for External Trigger to take effect.

Usage:

Users can select the trigger state that will operate with their systems. (If using an object detector, use Active Closed.)

Definition:

When enabled for Active Closed the triggering device imposes a current on the optoisolator to activate the read cycle. When enabled for Active Open the triggering device interrupts the current to the optoisolator to activate the read cycle.

Serial Trigger

Usage: Useful in applications where a read cycle needs to be initiated and/or ended

by user-defined serial characters. Definition: An online host command composed of a single ASCII host serial trigger

character that initiates or ends the read cycle.

Trigger characters are of two types: delimited and non-delimited. A delimited

character is enclosed within angle bracket delimiters < >.

A non-delimited trigger character is one that either starts or ends the read

cycle and is NOT enclosed by delimiters such as < >.

Rules for Trigger Modes

•In External Edge the scanner looks only for the Start Trigger Character and ignores any End Trigger Character that may be defined.

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

•In Serial Data and External Edge trigger mode, command, either a Start Trigger Character or a hardware trigger can start an Edge trigger read cycle.

Serial Trigger Character (Delimited)

Usage:

Definition: A delimited trigger character is one that starts the read cycle, is enclosed by

Read Cycle

Start Character (Non-Delimited)

Usage: Useful in applications where a different character is required to start a read

cycle. Works with External Edge, External Level, and Serial Data and External Edge.

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

not enclosed by delimiters such as < and >.

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

Stop Character (Non-Delimited)

Usage: Useful in applications where a different character is required to end a read

cycle. Works with External Level only.

Definition: A single ASCII host serial trigger character that ends the read cycle and is not

enclosed by delimiters such as < and >.

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

End of Read Cycle

Note: When to Output

Definition:

The read cycle is the time during which the scanner will attempt to read and decode a symbol. At the end of a read cycle the scanner stops reading symbols and sends the symbol data or No Read message to the host.

must be set to

End of Read Cycle

before this command can be active.

End of Read Cycle Mode

Definition: A read cycle can be terminated by a new trigger, a timeout, or a combination

of both.

Serial Cmd: <K220,end of read cycle,read cycle timeout>

Default: Timeout Options: 0 = Timeout 1 = New Trigger 2 = Timeout and New Trigger

Note: When operating in Continuous Read or Continuous Read 1 Output, the scanner is always in the read cycle.

Timeout

Usage: Typically used with Serial or Edge and Continuous One.

It is effective in highly controlled applications when the maximum length of time between objects can be predicted. It assures that a read cycle ends before the next bar-coded object appears, giving the system extra time to decode and transmit the data to the host.

Definition: Timeout ends the read cycle when the time set in Read Cycle Timeout

elapses or “times out.” If in Continuous Read 1 Output, a timeout initiates a new read cycle and

allows the same symbol to be read again. With either External Edge, Serial Data, or Serial Data and External Edge

enabled, a timeout ends the read cycle and symbol data or a No Read message

is sent to the host. With External Level enabled, the read cycle does not end until the falling

edge trigger or a timeout occurs. The next read cycle does not begin until the next rising edge trigger.

4-14

MS-890 Industrial Automation Scanner User Manual

Page 85

Read Cycle

New Trigger

Usage: New Trigger is an effective way to end a read cycle when objects move past

the scanner at irregular intervals (not timing-dependent).

Definition: New Trigger ends the current read cycle and initiates a new one when a new

trigger occurs. New Trigger refers only to a “rising edge” trigger. With either External Edge, Serial, or Serial or Edge enabled, an edge or

serial trigger ends a read cycle and initiates the next read cycle. In the case of External Level, a falling edge trigger ends the read cycle but

the next read cycle does not begin until the occurrence of the next rising edge trigger.

Note: When New Trigger is enabled and if not in External Level mode, Laser On/Off will have no effect. When No Reads occur, the laser will remain on.

Timeout and New Trigger

Usage: Useful in applications that require an alternative way to end the read cycle.

For example, if an assembly line should stop completely or the intervals between objects are highly irregular.

Definition: Timeout and New Trigger is identical to Timeout, except that a timeout or a

new trigger (whichever occurs first) ends the read cycle.

MS-890 Industrial Automation Scanner User Manual

Page 86

End of Read Cycle

Read Cycle Timeout

Usage: Useful in many tightly controlled applications which require a read cycle to

end before the next object appears and therefore need the flexibility of a timeout adjustment.

Definition: Read Cycle Timeout is the time span of the read cycle and is represented in

10 ms increments. It is used in conjunction with External Edge or Serial Trigger.

Serial Cmd: <K220,end of read cycle,read cycle timeout> Default: 100 (x 10 ms) Options: 0 to 65535. (Divide any positive number entered by 100 to determine the time

in seconds.)

Note: A minimum setting of 2 is recommended. Note: Timeout or Timeout or New Trigger under End of Read Cycle must

be enabled for Read Cycle Timeout to take effect.

Read Cycle

Good Decode Reads

Usage: This is a very useful feature to increase reliability of reads for symbologies

that do not have internal error checking such as Pharmacode.

Definition: The number of decodes (from 1 to 31) required per symbol before a symbol’s

decoded data is sent. It requires the scanner to successfully decode a symbol a designated number of times (not necessarily consecutively) before it is sent. If it doesn’t achieve the number of good reads during the read cycle, then a No Read will be sent.

Note: Higher settings will decrease throughput speed.

Serial Cmd: <K221,good decode reads,mode>

Default: 1 Options: 1 to 31

Good Decode Output Mode

Definition: Affects how the scanner counts symbols that it reads successfully. Serial Cmd: <K221,good decode reads,mode>

Gain Settings

The settings in this section are typically adjusted by Calibration, or by qualified technicians. They are included here for special applications. Before making changes to individual commands in this section, it would be advisable to make a written record of current settings.

Gain Adjustment

Usage: Can be useful for fine-tuning gain or when portions of analog signals spike as

in the case of specular reflection or extraneous noise.

Caution: Changes to Gain are typically done by qualified technicians in Calibration. See Chapter 9, Calibration.

Definition: Sets a voltage amplitude value for the analog circuitry. Serial Cmd: <K504,gain adjustment,AGC mode> Default: Default is 40 (nominal). Gain is optimized at the factory before shipment; the

default value may not be 40.

Options: 0 to 255

AGC Mode

Definition: Tracks peak signals and selects an amplitude reference point to sample the

analog signals for converting to digital.

Read Cycle

Automatic Gain Control (AGC) Settings

Important: AGC settings apply to both AGC and symbol detection.

Symbol Detect Status

Usage: During the read cycle, the scanner counts the number of bar and space

transitions defined in the Transition Counter. If the count matches or exceeds the threshold, the scanner will perform AGC routines.

Definition: AGC is the acronym for Automatic Gain Control. AGC increases the depth of

field by attempting to maintain signal strength at a constant level regardless of the range of the symbol.

Serial Cmd: <K505,symbol detect status,minimum number of transitions>

Default: Disabled Options: 0 = Disabled 1 = Enabled

Minimum Number of Transitions

Usage: Can be useful in certain application where extraneous objects in the field of

view might require a higher threshold.

Definition: Determines the number of bar/space transitions that must be read before a

symbol is considered present and AGC can be resolved.

Serial Cmd: <K505,symbol detect status,minimum number of transitions>

Default: 14 Options: 1 to 255

Large Intercharacter Gap (Code 39)

Usage: Large Intercharacter Gap is helpful for reading symbols that are printed

out of specification. Caution: Do not use Large Intercharacter Gap with Narrow Margins

enabled since a large intercharacter gap (over 3x) could cause a narrow margins (5x) to be interpreted as an intercharacter gap.

Full ASCII Set (Code 39)

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

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

Since Full ASCII Set requires two symbol 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 scanner can read the full ASCII character set, from 0 to 255.
