1. Overview
Iradion Infinity Series lasers offer to the user the ability to communicate with the
laser using RS232 communication. The RS232 communication signals are available
on one of the two ports on the rear-side of the laser: J7 HD-15 style, or J8 RJ45
style.
Iradion offers users a convenient GUI interface, or the user can interface directly using a
predefined command set.
2. Equipment Required
2.1. Windows PC (windows 7 OS or higher) with IRADION COMM WRITER II
software installed and USB to serial port converter or build in serial port.
3. Software installation.
•The software installation package consists of two files.
- Setup.exe and Setup.msi.
•Execute the setup.msi file.
•Follow the prompts to install the software (see figure 1 to figure 4).
•Windows will ask permission to install the software, this will
require administrative access to the computer. Answer ‘yes’.
•By default the software will be installed to the default program file
location. In most computers, this will be c:\program files or
c:\program files (X86). It will create a directory
IRADION\CommWriter2. The setup program will allow you to
change the destination of the files. (see figure 2)
•A shortcut will also be placed on the user’s desktop. (see figure 5)
•Note: In some cases, the setup program may require you to
update windows OS. An internet connection is required to perform
the update. The setup program will download required updates if
necessary.

4. Using the Software
4.1. Confirm the serial port on the windows PC is functional.
4.2. Connect the serial port (PC) to the IRADION CO2 laser’s serial port using
appropriate cabling. Refer to IRADION LASER user guide on how to connect
the cabling.
4.3. Run IRADION COMM WRITER II software. There should be short cut on the
desktop for the software.
4.4. Setup the communication port.
4.5. Click on the comm port combo box (see figure 6 and figure 7).
4.6. Select the available comm port. The comm port combo box contains the
name(s) of all serial port found installed in computer. If there is no comm port
showing in the combo box, the computer had failed to locate a serial port
installed. The software will not function without a working serial port.
4.7. Click on the Start monitor loop button to open the comm port and start
automatically polling the status of the laser. (see figure 6) Note: You have to
select a comm port first, otherwise this button will be disabled. Upon success
on initializing the comm port, the status bar (bottom of the application) will show
the connection status as connection:true. The comm port opened also will be
show in the status bar’s left side.
4.8. The Command window will show all available commands. (see figure 8)
4.9. Select desired command to send by clicking on it in the command
windows. Send the command by clicking on the Send Command button.
Alternative way to send command is to double-click on it inside the
Command window.

4.10. If the communication to the laser is successful, the application will start
filling in following information boxes by polling the laser:
•Laser state.
•Simmer duty
•Pulse stretch
•Temp
•Interlock
•Temp Warning
•Laser fault
•Laser VDC
•Laser serial
•Laser voltage Setting
•Rated power
•Measured power
•Auto fan
•Firmware version
•Mod low ground
4.11. If the communication failed, the application will display a failure status in
the status bar. The program will time out after 10 seconds and signal a
failure if the communication did not respond. A dialog box will be shown
to reset the serial port or to exit the application. (see figure 9)

5. LC Command Packets Listing
4.1 This section describes the packet protocol for transmitting and receiving data
via the RS232 com line to the Iradion Laser Controller Card.
4.2 Note: The Iradion Controller Card is programmed to reply only when queried
and does not automatically transmit strings.
6. Serial Data Format
6.1. The serial data format is RS232 - 19.2K baud, 8 data bits, no parity and 1 stop bit.
7. Command Packet Format:
7.1. The command packet is made up of ascii text characters as described below.
Start
Cmd
Length
Data
Data End
Check
End
8. Packet Characters:
Start $ character.
Cmd 2 characters, ascii hex format 00 –
FF. Length * 2 characters, ascii hex
format 00 –FF.
Data 0 to n characters, ascii hex format 000000…N –
FFFFFF...N Data End & character.
Check 2 characters, ascii hex format 00 –FF.
End 2 characters, carriage return and line feed.
Length - Number of characters in the packet includes Start to End
characters. A Cmd packet with no data field has a length of ten.
9. Check Character Calculation
9.1. The check characters are calculated by adding the Start, Cmd, Length, Data
and Data End ascii characters then representing the byte value as two ascii
characters.
10. Command Response:
10.1. After a valid command is processed a response packet is sent.
