Remote Communications
The communication capability of the marking system software
allows you to control the laser from remote I/O devices. Remote
communications can be performed by connecting to a Host
computer, an optional I/O card, or an optional two-axis Auxiliary
Controller.
The rear panel of the controller also provides a connector to
monitor output signals that report the status of the shutter, laser
emission, and fault conditions.
Host Communications.
Remote communications may be
executed from a host computer using RS-232 or Ethernet
(TCP/IP) connections to the system computer (i.e., the PC
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
Operation Manual
supplied with the
laser marking software.
I/O Card.
Telesis offers an optional I/O card that provides six
input signals (Start Print, Abort, and four programmable inputs)
and six output signals (Ready, Done, Paused, and three
programmable outputs). The I/O card is available in the
following kits. For more information on using the optional I/O
card, refer to the Telesis
Optional I/O Card Installation
Supplement
supplied in each of these kits.
Kit #53920
This kit is available for all Telesis laser systems.
It includes the I/O Card, SIPs resistor packs (pre-installed),
the software driver CD, and installation documentation.
This kit does not provide opto-isolated signals. If this kit is
used, it is the responsibility of the installer/integrator to
provide opto-isolation between remote I/O devices and the
I/O card. Refer to the OEM
User’s Guide
for signal
limitations.
Note: Telesis does not endorse direct connection of I/O
signals to the I/O card. Direct connections to high
current/high voltage devices will damage the card.
Kit #53928
This kit is available for all laser systems that use
the Merlin II LS Laser Marking Software. It includes Kit
#53920 (above), plus the Telesis I/O Interface Module and
two cable assemblies.
This kit provides opto-isolated signals between remote I/O
devices and the I/O card through the Telesis I/O Interface
Module. Additional opto-isolator board assemblies or
opto-isolated I/O rack assemblies are not required when
the interface module is used.
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 six input and six output signals to and
from the laser marking system, and for connecting the optional
auxiliary axes: vertical (Z) axis, rotational (Theta) axis, and
linear (L1 and L2) axes.
Environmental considerations must be taken into account when
installing the auxiliary controller concerning contaminants and
EMI susceptibility. For details, refer to the
Installation/
Maintenance Manual
supplied with the controller.
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 marking system 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 ("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 ("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 ("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 ("P") indicates the data extracted from the
host message is the name of the pattern to be loaded.
81
Message type 81 ("Q") updates the text in the first query
text buffer (buffer 0) with the data extracted from the host
message.
86
Message type 86 ("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 ("v") updates the first text field
encountered in the pattern that contains a variable text flag
that matches the specified string length.
If the host is providing the Message Type within the transmitted
text string, enter "0" in the Message Type parameter text box
displayed on the Programmable tab of the Host/Setup window.
0
Message type 0 (zero) indicates that the host will provide
the message type, field number (if applicable), and data (if
applicable). This option allows more flexibility by
delegating the message type selection to the host on a
message-by-message basis. It also allows you to direct data
to specific fields and/or query text buffers.
The host can use Message Type 0 to provide data to the
marking system. The marking system will insert data
transmitted with the message into the appropriate location.
