OWNERS MANUAL | Cobolt 04-01 Series | D0105-I October 2022
Operation via data port
To communicate with a Cobolt 04-01 lasers use the mini-USB data port on the external controller. The appropriate
communication cable is provided with all lasers. Determine which communication protocol (USB or RS-232) your
system is configured for by either checking the label on the mini-USB data port or from the model number (see 3.1).
Handshaking
Under no circumstances does the system initiate communication; it only transmits characters in response to a
message. Every message generates a response, either a numerical value or
the acknowledgment string “OK”. In the
event that the system receives a message that it cannot interpret, it responds: “Syntax error: illegal command”. Every
system response is terminated by a carriage return (ASCII 13) and a full stop is used with floating numbers.
RS232 communication
Cobolt 04-01 laser controllers are configured for either RS-232 or USB configuration. The system is shipped from the
factory with a fixed baud rate (115200). The other serial port parameters are: 8 data bits, 1 stop bit and no parity.
Hardware flow control is not supported. Each command must be terminated by a carriage return. All commands are
case-sensitive. Leading and trailing white space is ignored, but command arguments must be delimited by a single
space character (ASCII 32).
USB communication
To support USB communication, the appropriate USB driver will be automatically installed on the computer with
Windows 10 and up, when the laser is connected for the first time. If a computer with another or older operating
system is used, then the USB driver must be actively downloaded from the Hübner Photonics website
NOTICE
If using an RS-232 configured Cobolt 04-01 laser, do not install any USB driver, regardless of
operating system.
