Introduction
About the HS-21 and HS-41X Handheld Readers
About the HS-21 and HS-41X Handheld Readers
The HS-21 is a general-purpose 2D reader. Its many features include dual field optics for
both high density and wide angle performance, a ruggedized design, IP54 sealing against
dust and water, and compact size.
The HS-41X is a special-purpose 2D reader for decoding direct part marks (DPM).
Microscan’s X-Mode decode algorithms make the HS-41X an ideal solution for reading difficult
marks on many surfaces, including PCBs, electrical components, castings, and sheet metal.
Its tough design makes it a good choice for manufacturing and light industrial applications.
Both readers can be configured and tested easily using the intuitive tree controls and user
interface of Microscan’s ESP Software.
Note: The HS-21 and HS-41X have unique algorithm licenses, and the HS-21 cannot be
field-upgraded to an HS-41X.
About This Manual
This manual provides complete information on setting up, installing, and configuring the
HS-21 and HS-41X. The chapters are presented in the order in which the reader would be

Practice Targeting
When the reader is closer to the symbol, you will
see two separate bars.
As you draw the reader away from the symbol, the
two bars converge. At the optimal distance, the
two bars should just be touching, as shown above.
ABCDEFGHIJKLMNOP
When first connecting, allow approximately 3 seconds for the reader to initialize.
1. Hold the reader steady and point it at a test symbol.
2. Squeeze and hold the trigger.
3.
Move the reader toward or away from the symbol in a fluid motion until the two side-by-side
blue bars converge in the middle of the symbol. When the reader is at the optimal distance
(about 4 inches or 10 cm), it will decode the symbol and will beep and vibrate while
emitting a green LED flash to indicate a Good Read. At this optimal distance, the two
blue bars should just be touching. Note that the bars overlap as you continue to draw
the reader away from the symbol.
4. If no decode occurs, slowly draw away from or move closer to the symbol while holding
the blue bars centered steadily on the symbol.
Test Symbol
Targeting Suggestions
• Typically, you should not hold the reader exactly perpendicular to the symbol. Position
the reader at an angle to avoid specular reflection.
• Use smooth, fluid motion when targeting the symbol. Do not wave the reader side-to-side
or up-and-down, or attempt to sweep across a symbol, as sudden movements will create
blurred images.
• The reader is omnidirectional and can decode symbols in any orientation. When decoding
1D symbols, be sure that the entire symbol falls well within the field of view.

Communications Overview
Whenever you default the reader, it will return to the default settings of whichever interface
you are using. Defaulting the reader does not remove preamble and postamble formatting.
The reader is in USB Native (HID) by default.
USB
With USB communications, the reader connects directly to the host’s USB port from which it
draws its power. Data is displayed by any open Windows-based program that can capture
text in USB Keyboard Mode.
RS-232
With RS-232 communications the reader communicates with the host through a communications
program such as ESP’s Terminal.
Default settings for establishing RS-232 communications are:

Keyboard Mapping
The Keyboard Mapping feature provides alternatives for keyboards that do not conform
to U.S. English mapping.
Note: Universal Keyboard mapping is slightly slower than the other language-specific
options, because it maps data by reference to the full set of ASCII characters. The
advantage of Universal Keyboard mapping is that it allows any language and keyboard
layout to be mapped.
Important: Keyboard Mapping is not to be confused with USB Keyboard Mode, which
has an entirely different function—namely to enable USB cabled communications.

Reader Packet Format
Data that is sent from the reader to the host in Raw format is sent without packet framing
or check characters. One-Way communication is in a raw format, no response is expected
from the host, and data is not resent.
Packetized data is sent with framing (a preamble communicating the amount of data to be
transmitted, and a postamble containing error detection) and check characters, and a
response is expected from the host. Two-Wa y communication is in packet format.
Reader to Host Packet Size
The Reader to Host Packet Size is the amount of data (in bytes) that is sent to the host in
packet format. This feature allows you to set the maximum allowable packet size.
Expect Host Response
When Expect Host Response is enabled, the reader will re-transmit data if it doesn’t
receive acknowledgement from the host.
Reader Send Retry Count
Reader Send Retry Count sets the number of times the reader will re-transmit data
before abandoning further send attempts. The minimum retry count is 1, which represents
the initial transmission.
Host Acknowledgement Timeout
The Host Acknowledgement Timeout is the amount of time (in seconds) that the reader
will wait for an acknowledgement from the host before re-sending data.

Targeting Zone Tolerance
Targeting Zone Tolerance
Targeting Zone Tolerance is particularly useful in environments where closely spaced
symbols of various sizes need to be targeted. It allows the reader to narrow the field of
view relative to the size of a symbol, and to determine the distance the target must be from
the symbol for a decode event to occur.
See Window of Interest for more precise control of the active pixel area.
The default Targeting Zone Tolerance is 1600%.
Formula for calculating Targeting Zone Tolerance:
2 x distance from target to symbol (in pixels) / symbol width or height (in pixels) x 100

Camera Settings
Camera Settings allow you to set AGC Sampling Mode, to set the percentage values for
Illumination, Exposure, and Gain, to set the AGC Frame Adjust Count, and also to define
Window of Interest dimensions.
AGC Sampling Mode
When AGC Sampling Mode is set to Automatic (default), each time a No Read occurs,
the reader adjusts the gain and exposure for the next capture to optimize symbol contrast.
The values for Illumination, Exposure, and Gain can be set to any value between 0%
and 100%. The default values are shown below.
AGC Frame Adjust Count
Automatic Gain Control (AGC) is a system that controls gain in order to maintain high
performance over a range of input levels. Gain is essentially the ratio of output to input.
Gain settings affect how the reader decodes symbols and captures images.
AGC Frame Adjust Count sets the number of image frames captured and discarded
before the main image capture. This feature gives the gain control time to adjust.

Fixed Symbol Length Status
When enabled, the reader will check the symbol length against the symbol length field. If
disabled, any length will be considered valid.
Symbol Length
Specifies the exact number of bars that must be present for the reader to recognize and
decode the Pharmacode symbol.
Minimum Bars
Sets the minimum number of bars that a Pharmacode symbol must have to be considered
valid.
Bar Width Status
If set to Mixed, the reader will autodiscriminate between narrow bars and wide bars. If set
to All Narrow, all bars will be considered as narrow bars. If set to All Wide, all bars will be
considered as wide bars. If set to Fixed Threshold, it will use the fixed threshold value to
determine whether the bars are narrow or wide. The Bar Width Status setting will be
ignored when the reader is able to tell the difference between the narrow and the wide bars.
Direction
Specifies the direction in which a symbol can be read.
Fixed Threshold Value
Used when Bar Width Status is set to Fixed Threshold. Defines the minimum difference
in pixels that will distinguish a narrow bar from a wide bar.

Composite
Composite consists of a 1D component associated with an adjacent 2D component. A
successful decode is required for both the 1D and 2D components before the reader outputs
a result. When Composite is enabled, the unit decodes the 1D component first.
Important: EAN-8, EAN-13, UPC-A, and UPC-E cannot be decoded individually when
Composite is enabled.
Maximum Decodes per Read
Maximum Decodes per Read represents the maximum number of candidate symbols in
the field of view (1 - 100) that can be decoded during a read cycle. Note that decode
speed will decrease as the Maximum Decodes per Read value is increased.

This section includes instructions on setting up conditions for changing input/output electrical
transitions for control of the reader’s internal and external devices. A discrete I/O (in/out) signal
is an electrical transition from one voltage level to another so that digital switching can occur.
The Data Matrix symbols in this section can also be decoded to configure I/O parameters.
