The laser marking head incorporates the latest technology in
sealed-tube, RF-excited, continuous wave, carbon dioxide
lasers, providing excellent output power, stability, and reliability
in a rugged compact modular package.
Marking Field Size
The size of the marking field is dependent on type of lens
installed on the laser marking head. See Flat-Field Lens.
Marking Depth
Simple laser parameters can be operator programmed to create
depths ranging from simple surface discoloration, shallow laser
etching, or deep laser engraving. Marking depth is dependent
on several factors including material, lens type selected, and
laser marking parameters. Please contact Telesis for the proper
setting for your specific application.

Dimensions drawing
Marking Head Power ............... 680 watts (approximate)
Mounting Weight ..................... approx. 26.3 Kg (58 lbs.)
Flat-Field Lens
The flat-field lens is key to the marking performance of the
system. This is the final coated optical lens that the beam will
pass through before it strikes the marking target. This lens is
called a flat field lens because when the beam is focused, the
focus lies in a plane perpendicular to the optical axis of the lens.

Lens
Dual-Sensor Shutter Circuit
(mm)
The CO30A laser marking head employs two separate sensors to
detect the closed-state of the laser shutter mechanism. The
sensor signals can be monitored at the Outputs Connector on the
back panel of the laser controller. When the shutter is open, the
sensor feedback signals are OFF. When the shutter is closed, the
sensor feedback signals are ON.
Visible Red Aiming Diode
Laser marking head includes a visible red diode that can be
viewed on the work surface without the need for protective
safety goggles.
The aiming diode provides a safe and convenient aid for laser
setup and part programming. Since the red beam is located after
the shutter, the aiming beam may be used with the shutter
opened or closed. Additionally, the visible red beam may be
used with the lasing beam during the marking cycle. Note that
protective eyewear must always be worn when the laser is in
operation.

CO30A Laser Marking System
SYSTEM SOFTWARE
The powerful Telesis Merlin II LS Laser Marking Software is a
Windows® based software package that comes standard with the
laser marking system. It is a graphical user interface that makes
marking pattern design quick and easy. The WYSIWYG (whatyou-see-is-what-you-get) interface provides a to-scale image of
the pattern as it is created. Just “click and drag” for immediate
adjustment to field size, location, or orientation.
SYSTEM COMPUTER
The laser system requires an IBM-compatible computer for
running the Merlin II LS Laser Marking Software. The system
computer may be an external device connected to the laser
controller, or it may be embedded within the controller itself.
If supplied by Telesis, the Laser/Galvo Controller board and the
Merlin II LS are installed in the system computer prior to
shipment and the entire unit is tested as a laser marking system.
Warranty for the computer, keyboard, monitor, and peripherals
defaults to the original equipment manufacturer.
The Merlin II LS software includes tools to create and edit text
at any angle, arc text, rectangles, circles, ellipses, and lines.
Multiple fields may be grouped and saved as a block to form a
logo. Existing DXF files can also be imported for marking. Nonprintable fields can be created to clearly display a graphical
representation of the part being marked.

CO30A Laser Marking System
Remote Communications
The communication capability of the laser marking software
allows you to control the laser from a remote source. Remote
communications can be performed by connecting to a Host
computer, an optional two-axis Auxiliary Controller, or to
remote I/O devices.
Host Communications. Remote communications may be
executed from a host computer using RS-232 or Ethernet
(TCP/IP) connections to the system computer running the
Telesis laser marking software. The software provides
parameters to define the data transmitted to and from the host.
For more information on using and configuring these
parameters, refer to the Merlin II LS Operating Instructions.
Two-axis Controller. Telesis offers an optional two-axis
controller for all laser systems that use the Merlin II LS Laser
Marking Software. The auxiliary controller provides an interface
for connecting a Z-axis tool post and/or a Theta-axis rotary drive
unit. An optional board allows connection of two additional
linear axes. For installation details, refer to the Auxiliary
Controller Installation & Maintenance Manual supplied with
the two-axis controller.
I/O Kits for Systems with External Computers. Telesis offers
optional kits that provide programmable I/O signals in addition to
the standard input signals (Go, Abort, Input 1 through Input 4) and
standard output signals (Done, Ready, Paused, Output 1 through
Output 3). For more information on connecting and using the
additional I/O signals, refer to the I/O Installation Supplement
provided in each of the kits.
Kit #53920 provides an additional 6 inputs and 6 outputs. It
includes the I/O board, pre-installed SIPs resistor packs,
software driver CD, and installation documentation. This kit
does not provide opto-isolated signals. Telesis does not
endorse direct connection of I/O signals to the I/O board.
Direct connections to high current/high voltage devices
will damage the board. The installer/integrator must provide
opto-isolation between remote I/O devices and the I/O board.
Kit #53928 provides an additional 6 inputs and 6 outputs. It
includes the I/O board, pre-installed SIPs resistor packs,
software driver CD, Telesis Interface Module (#53423), two
cable assemblies, and installation documentation. This kit
provides opto-isolated signals between remote I/O devices and
the I/O board using a Telesis interface module so additional
I/O racks or opto-isolated board assemblies are not required.
Communications Protocol
Two types of host interface are supported (RS-232 or TCP/IP) and
two communication protocols are provided through the Merlin II LS
laser marking software: Programmable and Extended.
Programmable Protocol. Programmable protocol provides
one-way (receive only) communication with no error checking
or acknowledgment of the transmitted data. You may use
Programmable protocol to extract a continuous portion of a
message string to print. This can be used with a host computer
or a bar code scanner. Note that XON/XOFF Protocol applies
even when Programmable Protocol is selected.
The Programmable Protocol Message Type identifies the type of
message sent from the host. It determines how the marker uses
the data it extracts from the host message string when
Programmable Protocol is used.
49
Message type 49 (ASCII 1) overwrites the content of the
first text-based field in the pattern with the data extracted
from the host message. Note that if the field contains
message flags, they will be overwritten, not updated.
65
Message type 65 (ASCII A) updates the Offset Angle
parameter with the data extracted from the host message.
Syntax for the transmitted string is ±n where ± is a positive
or negative sign and n is an integer that represents the offset
angle for the marking window.
72
Message type 72 (ASCII H) updates the Offset X/Y
parameters with the data extracted from the host message.
Syntax for the transmitted string is ±X.X, ±Y.Y where ± is a
positive or negative sign, X.X represents the X-axis offset
distance, and Y.Y represents the Y-axis offset distance.
80
Message type 80 (ASCII P) indicates the data extracted
from the host message is the name of the pattern to be
loaded.
81
Message type 81 (ASCII Q) updates the text in the first
query text buffer (buffer 0) with the data extracted from the
host message.
86
Message type 86 (ASCII uppercase V) updates the text in
the first variable text field in the pattern with the data
extracted from the host message.
118
Message type 118 (ASCII lowercase v) updates the first text
field encountered in the pattern that contains a variable text
flag that matches the specified string length.
0
Message type 0 (zero) indicates that host will provide
message type, field number (if applicable), and data;. This
delegates message type selection to the host on
message-by-message basis. The host message must use
the format:
I/O Connector for Systems with Embedded Computers.
Controllers configured with an embedded computer provide an
opto-isolated DB26P I/O connector. Separate I/O racks or optoisolated board assemblies are not required. In addition to the
standard input signals (Go, Abort, Input 1 through Input 4) and
standard output signals (Done, Ready, Paused, Output 1 through
Output 3), this connector provides two programmable inputs and
two programmable outputs. For more information on connecting
and using the opto-isolated I/O connector, refer to the CO30A
Installation & Maintenance Manual.
Tnn<string>
where:
T
= the message type (1, A, H, P, Q, V, or v)
nn
= the two-digit field number or query text buffer
where data will be placed.
Note: Not used with Message Types A, H, P.
<string> = the pattern name to load (Message Type P).

CO30A Laser Marking System
Communications Protocol (continued)
Extended Protocol. Extended protocol provides two-way communication with error checking and transmission acknowledgment. It is
designed to provide secure communications with an intelligent host device using pre-defined message formats and response formats where
serial communication is a vital part of the marking operation.
All communications are carried out in a parent/child relationship with the host being the parent. Only the host has the ability to initiate
communications. The following describes the Extended Protocol message format as sent from the host to the Merlin II LS software.
SOH TYPE [##] STX [DATA] ETX BCC CR
where:
SOH
ASCII Start of Header character (001H). The system
ignores all characters received prior to the SOH.
TYPE
A single, printable ASCII character that defines the
meaning (type) and content of the message
downloaded from the host, where:
1
Message Type 1 provides data to a text string
in the pattern or polls the pattern for data.
See [DATA] for details.
[##]
Optional two-digit ASCII number that specifies the
Station ID of the system in multi-drop network
applications. The ID may range from 00-31. Note that
“00” is reserved for applications where only one
controller is used. In such applications, this field may
be eliminated and “00” will be assumed.
STX
ASCII Start of Text Character (002H).
[DATA] Character string that may be required for certain
message types (e.g., Type 1, A, E, H, P, Q, or V).
A Message Type A provides data to the system
Offset Angle parameter for the marking
window or polls the system for data.
See [DATA] for details.
Typically, data is sent in the format:
nn<string>.
where:
E Message Type E allows the host to take the
machine offline. It also provides the option of
displaying an error message box with the
provided data string. See [DATA] for details.
nn
<string> = the data to be inserted into the field or
the query text buffer, as applicable
(Message Types 1, Q, or V).
or
the pattern name to load
(Message Type P).
or
the value of the X/Y Offset
(Message Type H).
or
the value of the Offset Angle
(Message Type A).
G Message Type G initiates a print cycle.
H Message Type H provides data to the system
X/Y Offset parameters or polls the system for
data. See [DATA] for details.
I
Message Type I polls the system for the I/O
status.
O Message Type O places the marker online.
This allows a host computer to reset. For
example, this may be used to recover from a
power outage when the marker is unattended.
P Message Type P loads a pattern or polls the
system for the current pattern name.
See [DATA] for details.
ETX
ASCII end of text character (003H).
BCC
Optional Block Check Code that is generated and sent
to improve link reliability by providing fault detection.
The BCC is calculated by taking an eight bit addition of
the TYPE and DATA TEXT characters and
transmitting them as a three digit ASCII decimal
number in the range from 000 to 255. If the sum is
greater than 255, the most significant bit overflows and
is discarded.
CR
ASCII Carriage Return Character (00DH).
Q Message Type Q provides data to the system
query text buffer or polls the system for data.
See [DATA] for details.
S
Message Type S polls the system for the
machine status. The machine status is returned to
the host in an eight-character hexadecimal mask.
V Message Type V provides data to a variable text
string in the pattern or polls the pattern for data.
See [DATA] for details.
