About the MS-710 Scanner

The MS-710 is a programmable, fixed-mount, high-speed scanner that reads and
decodes a wide variety of bar code symbols using a 10-sided spinning mirror to
project laser beams over a wide scan angle.

A user interfa c e program, the ESP (Easy Setup Program), can be downloaded from our
web site (www.microscan.com) and runs on Windows 2000 or Windows XP operating systems.
Alternately, configuration commands can be sent from an embedded, menu-driven terminal
program, or directly by host serial command strings.

MS-710 scanner. The chapters follow the ESP menus w hich are presente d in the order i n
which a scanner might be setup and made ready for industrial operation.

Chapter 1, “Quick Start” provides overall step-by-step instructions for getting your

scanner operational with specific “go to” references to other chapters and appendices.
The appendices include specifications, reference tables of serial commands, ASCII ch ar -

acters, multidrop setup and addresses, as well as other useful information relating to
bar coding and electrical and mechanical setups for the scanner.

Highlighting

Serial commands, selections inside instructions, and menu defaults are highlighted in

red bold. Cross-references are hi gh lighted in blue bold. Web links and outside refer

ences are highlighted in blue bold italics. References t o menu topi cs are highligh ted in
Bold Initial Caps. References to topic headings within this manual or other documents
are enclosed in q uotation marks.

Host Communications

There are three ways the scanner can communicate with a host:

1. Microscan’s Windows™ based ESP™, the preferred method which offer s point­and-click ease of use and visual responses to user adjustments.

2. Serial commands such as <Kr1> can be sent from a terminal program. They can
also be sent from the Terminal window within ESP.

3. Embedded onboard menus are accessed from a terminal window with a <D>
command.

About ESP

ESP is composed of two basic modes Setup

Mode and App Mode (applications). The icons

shown here are used to move between these
modes and are located in the upper left corner o f
the ESP window.

In the App Mode, cli ck the Configuration icon
to bring up the configuration views for Read Cycle, Symbolo-

gies, I/O, Matchcode and Diagnostics.
Note: Throughout ESP, the term “reader” applies to both readers

and scanners.
For more information, see “Using ESP” in chapter 2.

Chapter 3 Communications

Point-to-Point with RTS/CTS

Usage: A scanner initiates a data transfer with an RTS (request-to-send) trans-

mission. 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 R S-2 32 standard.

Used only with RS - 232.

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

simple hardwa re handshaking pro tocol that allows a sc anner to initiate
data transfers to the host.

Serial Cmd: <Kf1>

Point-to-Point with XON/XOFF (Transmitter On/Off)

Usage: If an XOFF has been received from the host, data will not be sent to the

host until the host sends an XON. During the XOFF phase, the host is free
to carry on other chores and accept data from other devices.

Used only with RS - 232.

Definition: This option enables the host to send the XON and XOFF command as a

single byte transmission command of start (^Q) or stop (^S).

Serial Cmd: <Kf2>

Point-to-Point with RTS/CTS & XON/XO FF

3–Communications

Usage: Used only with RS - 232.
Definition: This option is a c ombination of Point-to-Point with RT S /C T S and

Point-to-Point with XON/XOFF.

Serial Cmd: <Kf3>

Polling Mode D

Usage: When in Polling Mode D, an address of 1 is automatically displayed on

the configuration screen. However, during transmission, a 1C hex poll
address (FS) and a 1D hex select address (GS) are substituted for the 1.

Definition: Like Point-to-Point, Polling M ode D requir es a dedicated connection to

the host; but unlike Point-to-Point, it requires an address and mu st
wait for a poll from the host before sending dat a.

Serial Cmd: <Kf4>

Multidrop

Note: See also “Multidrop Communications” on page A-29.
Usage: The MS-5000 can be used as a concentr ator to a single host port c onnec-

tion.

Definition: Multidrop allows up to 50 devices to be connected to a single RS-485

host, with the scan ner assigned an uni que address (from 01 to 50). When

Daisy Chain Mode

Usage: Used in applications where:

• A symbol might be scanned in both ladder and picket fence directions.

• A bar code symbol m ay b e p re s ent on multiple sides of a pa c ka ge.

• Bar code symbo ls a re pr es en ted at different depths.

Definition: In a daisy chain application, scanners are connected in tandem 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: <Kyaux port mode,baud rate,parity,stop bits,data bits,daisy chain ID

Options: 4 = Daisy chain
Function: Before the master scanner times out, it checks its auxiliary port for data.

a. The above example is based on the best case. Other factors such as baud rate, number of characters in

a given symbol, and the number of secondaries in the daisy chain can affect timing and may need
to be included in your calculations for complete accuracy.

status,daisy chain ID>

It should be set to wait at least mS fo r each secondary in the d aisy chain.
If no data is received within the read cycle timeout, the master sends a
noread message to the host. Otherwise the complete data is sent.

If for example the master scan ner 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 Multi-

symbol and a common multisymbol separator. If the master scanner
does not receive the expected number of symbols, noread messages are
appended to the data string to make up the difference between the num­ber of symbols enabled in Multisymbol and the number of sy mbols read.

For example, a master and two secondary scanners have Number of
Symbols 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: symbol data % noread % noread.

Conditions: The conditions for a daisy chain application ar e as

follows:

1. The master scanner’s trigger must be Serial
or External; the secondary scanne rs’ triggers
are configured for Serial.

2. All scanners are enab le d to Daisy Chain
mode.

3. Each scanner’s auxiliary port must be connect ed to the Host port of
its secondary scanner.

4. Each secondary scanner in the daisy chain must be set to send its
data no less than 20 mS before its preceding scanner.

5. All but the mas ter s cann er must have Postamble enabled and set
to CR (^M) only.

6. All but the master scanner must have their noread messages disabled.

7. If Multisymbol is enabled, Multisymbol Separator characters
must match in all scanners a nd Number of Symbols must be set
to number large enough to include all the symbols it may itself read
plus the number of symbols that it wil l be exp ecte d to relay to the

LRC Status

(Longitudinal Redundancy Check)

Usage: Used when extra data inte gr ity is required.
Definition: An error-checking routine that verifies the accuracy of transmissions. It

is the exclusive OR of all characters following the STX (start of text ) up
to and including the ETX (end of text). What this m eans is that the
binary representation of all the characters in a transmissions are
cumulatively a dded in a column and each resu lting odd integer is
assigned a 1 and each ev en integer a 0 (two 1s = 0, two 0s = 0, a 1
and a 0 = 1). The extra LRC character is then appended to the trans
mission and the receiver (usually the host) performs the same addition
and compares the results.

Usage: Used only when a response is required from the host. While in Multi-

drop, if the scanner does not receive an ACK or NAK from the host afte r

sending polled data, it will act on a fault. The scanner can be set to wait

indefinitely by setting Response Timeout to zero.
Definition: Time the scanner will wait before timing out if ACK, NAK, and ETX are

enabled, and a host response is expected.

Serial Cmd: <KAresponse timeout>

Usage: Used only when a host cannot receive data quickly enough and there is

enough time bet ween symb ols to allow data to be com pletely tr ansfer red.
It is rarely used since any setting other than zero will slow down commu
nications. Fo r example, a 200 setting will result in a 1/5 second delay
between each character that is transmitted.

Definition: The time interval in milliseconds between individual characters transmit-

ted from the scanner to the host.

Read cycles and triggering modes are at the heart of bar code scanning. After you’ve
established communications and completed basic read rate testing, you will need to
address the spatial and timing parameters associated with y our application. In a t ypical
operation a bar coded item moves along a line past a scanner. A sensor or timer acti
vates a read cycle during which the scanner actively searches for bar code symbols. You
will need to decide how to initiate the read cycle and how and when to end it. This sec
tion addresses these issues.

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 6 bar code symbols that can

be read in a single read cycle.

Continuous Read

Usage: Continuous Read is useful in testing bar code symbol readability or

scanner functions. It is not recommended for normal operations.

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

always in the read cycle, and it will attempt to decode and transmit
every scan crossing a symbol.

Trigger

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 bar code 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, if Timeout is set to one second, the scanner sends the symbol
data immediately and repeats the output at interv als 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 previo us symbol read.

Serial Cmd: <Kg1>
Caution: In automated environments, Continuous Read 1 Output is not recom-

mended 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 num ber greater than 1) .

Chapter 4 Read Cycle

External Trigger Level

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

ing apparatus are variable and t he t ime the scanner spends scanning
each object is not predictable. It also allows the user to determine if a
noread has occurred.

Definition: External Trigger 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 endures until the object moves out of the sensor
range and the active trigger state changes again.

Initiate Read Cycle:

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

End Read Cycle:

The same object, movi ng ou t o f the detector
beam, causes another change in the trigger
state, ending the read cycle.

Figure 4-1 Trigger Level

Associated waveforms assume
External Trigger State is set
to Active Closed.

4–Read Cycle

Serial Cmd: <Kg2>

Important: Level and Edge apply to the active logic state (Active Open or Active
Closed) that exists while the object is in a read cycle, between the rising edge and fall
ing 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.

MS-710 Scanner User’s Manual 4-7

-

Trigger

External Trigger Edge

Usage: This mode is highly recommended in any application where c onveying

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

Definition: External Trigger 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 outp ut
or, depending on End of Read Cycle setting, a timeout or new trigger
occurs.

Initiate Read Cycle:

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

Associated waveforms assume
External Trigger State is set

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 occurred.

Chapter 4 Read Cycle

Serial Data

Usage: Serial Data is effective in a hig hly controlled environment where the

host knows precisely when the object is in the scan zone. It is also useful
in determining if a noread 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 D ata trigger
behaves the same as an External Edge trigger.

Serial commands are entered inside corner brackets, such as <t>.

Serial Cmd: <Kg4>

Serial Data or Edge

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

that primarily uses an external sensing device but occasionally 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.

Serial Cmd: <Kg5>

MS-710 Scanner User’s Manual 4-9

Trigger

Trigger Filter Duration

Usage: Trigger Filter Duration is useful where trigger bo unce coul d cause false

triggers.

Definition: Trigger Filter Duration can prevent trigger bounce from falsely trigger-

ing the scanner by limiting the tim e in which trigger puls es c a n be
received.

Serial Cmd: <Kgtrigger mod e ,trigger filter duration>
Default: 78 (x 128 µS = 9984 µS)
Options: 2 to 255 (corresponding to 256 µS to .03 s in 128 µS steps)

External Trigger State

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

Usage: Users can select the trigger state that will operate with their systems. (If

using the Microscan object detector, use Positive.)

Definition: When enabled for Positive the triggering device imposes a current to

activate the read cycle. When enabled for Negative the triggering device
interrupts the current to activate the read cycle.

Serial Cmd: <Kjexternal trigger state>
Default: Positive

Serial Trigger

Usage: Useful in applications where a read cyc le needs to be initiated and/or

ended by user-defined serial ch aracters.

Definition: An on-line host command composed of a single ASCII host serial trigger

character that initiates or ends the read cycle.

Serial Trigger Character

Usage: Useful in applications where a single serial character enclosed in angle

brackets initiates the read cycle.

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

iters < > and can only be sent when the trigger mode is set to Serial
Data or Serial Data & Edge.

Serial Cmd: <Kiserial trigger character>
Default: GS (corresponds to ^] displayed in the embedded menu)

1 = New Trigger
2 = Timeout & New Trigger

Timeout

4–Read Cycle

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 ob ject appears, giving the system extra
time to decode and tran s mi t th e da ta to the host.

Definition: Timeout ends the read c ycl e whe n the time set in 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 & Edge

enabled, a timeout ends the read cycl e and symbol data or a noread 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 ed ge trigger.

4-12 MS-710 Scanner User’s Manual

Chapter 4 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 th e oc c urrence of the next
rising edge trigger.

(See Figure 4-1 on page 4-7 and Figure 4-2 on page 4-8 .)

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

Timeout or New Trigger

Usage: Used 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 or New Trigger

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

is identical to Timeout, excep t that a timeout

4–Read Cycle

Read Cycle Timeout

Usage: It is useful in many tightly controlled applications which require a read

cycle to end before the nex t 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 repre-

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

Serial Cmd: <Khend of read cycle mode,read cycle timeout>
Default: 100 (Corresponds to one second or 1000 mS)
Options: 0 to 65535. (Divid e any po sitive number entere d by 10 0 to dete rmine the

time in seconds)

Note: A minimum setting of 2 is recommended.
Note: Timeout or Timeout or New Trigger under End of Re ad Cy cle must be

enabled for Timeout Duration to take effect.

MS-710 Scanner User’s Manual 4-13

Good Decode Reads

Good Decode Reads

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

gies that do not have internal error checking such as Pharmacode.

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

bol’s decoded data is sent . It requires t he 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 noread will be sent.

Note: Higher settings will decrease throughput speed.

Serial Cmd: <Kmgood decode reads>
Default: 1
Options: 1 to 31

Note: When setting up, be sure to determine if the scanner’s scan rate is capable of
scanning your longest symbol the required number of times.

Default: 45 (nominal). Gain is optimized at the factory before shipment; the

default value may not be 45.

Options: 10 to 255

Scan Speed

4–Read Cycle

Usage: To ensure a minimum number of scans, faster scan speeds are typically

used for fast moving symbols and/or longer symbols with larger bar
widths.

Note: Scan beams move faster across symbols further out in the scan
range since the moving beam is being projected from a spinn ing mirror.

Definition: Allows the user to set the number of scans per second by controlling the

spinning mirror motor speed.

Serial Cmd: <KEscan speed>
Default: 40 (x 10 = 400 scans per second)
Options: 30 to 55 (x 10 scans per second)

MS-710 Scanner User’s Manual 4-15

Automatic Gain Control (AGC)

Important: AGC settings apply to both AG C gain control and symbol detection.

AGC Sampling Mode

Usage: AGC Sampling allows you to specify how automatic gain control sam-

pling will be done.

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 bar code symbol.

Serial Cmd: <KDgain,AGC sampling>
Default: Continuous
Options: 0 = Disabled 1 = Leading Edge 2 = Continuous

Disabled

Definition: When AGC Sampling is set to Disabled, gain levels can only be manu-

ally controlled by the Gain command.

Usage: Disabled is not recommended, but can be useful in certain applications

in which symbols do not require a large depth of field.

Leading Edge

Usage: Leading Edge is rarely used, but in some cases can improve scan rates

Interleaved 2 of 5

Usage: It is has been popular because it is the most dense symbology for print-

ing 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.

Definition: A dense, continuous, 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 firs t c ha racter and the in terleaved spaces representing the
second character. (A check digit is highly recommended.)

Important: You must set Symbol Length in order to decode I 2/5 sym­bols.

Symbol Length #1 (Interleaved 2 of 5)

Usage: With I 2/5, two symbol lengths can be defined. When using only one

symbol length in an application, setting Symbol Length #2 to 0 (zero)
to ensure data integrity is recommended.

Definition: Allows user to define the symbol length. B ecause I 2/5 is a continu ous

symbology, it is prone to substi tuti on e rrors. Hence, a s ymbol length m ust
be defined and a symbol must contain an e v en n umber o f d igits.

Note: If start, stop or check digits are used, they are not included in the
symbol length count.

Serial Cmd: <Krstatus,check digit status,check digit output,symbol length #1,sym-

bol length #2>
Default: 10
Options: 2 to 64, even

Since I 2/5 characters are paired, symbol length must be set to an ev en

number. If Check Digit is enabled, add 2 to your symbol length. For

example, if your symbol is 10 characters plus a check digit, then enable

Symbol Length for 12.

Note: Typically, when printi ng an I 2/5 symbol with an odd number of

digits, a 0 will be added as the first character.

Symbol Length #2 (Interleaved 2 of 5)

Usage: If using a second symbol, a zero or any even symbol length from 2 to 64

may be specified. If not using a second symbol, set Symbol Length #2

to 0 to ensure data integrity.

Definition: Allows user to define a second symbol length for I–2 of 5.

UPC Supplementals will not be decoded.

Enabled

When enabled, the scanner will try to decode a main and a supplemen tal. Howev er, if a
supplemental is not decoded, at the end of the read cycle, the main will be sen t by
itself. The UPC main and supplemental symbols are considered to be one symbol and
will be treated as such.

Required

When set to Required and either the main or supplemental symbo l is not read, a single
noread condition results. The UPC main and supplemental symbols are treated as one
symbol.

For example, if Supplementals is set to Required, Separator is enabled, and an
asterisk is defined as the UPC separator character, then the data will be displayed as:
MAIN * SUPPLEMENTAL.

Note: Under no circumstances will supplemental symbol data be sent without a main
symbol.

Note: If additional symbols—oth er than the main or supplemental—will be read in the
same read cycle, Number of Symbols should be set accordingly.

Usage: Match is used in an applic a t ion that requires s pe c if ic s ym b ol data infor-

mation and needs to sort, route or verify based on matching the specific
symbol data.

Definition: When set to Match, the scanner transmits symbol data whenever a sym-

bol data matches a master symbol. However, if Matchcode Type is set
to Disabled, it transmits on any good read.

Note: A noread can still be transmitted if Enabled.

Mismatch

Usage: Mismatch is typically used as a flag with in the host system to prev ent an

item from being routed in the wrong container.

Definition: With Mismatch enabled, the scanner tran s m its symbol data whenever

the symbol data information does NOT match the master symbol.
Note: A noread can still be transmitted if enabled.
