OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016
Operation via data port
Handshaking
Under no circumstances does the Controller initiate communication; it only transmits characters in response to a
message. Every message to the Controller generates a response, either a numerical value or the acknowledgment
string “OK”. In the event that the Controller receives a message that it cannot interpret, it responds: “Syntax error:”
followed by the complete command string (minus the termination character) that caused the error.
Every Controller response is terminated by a carriage return (ASCII 13) and a full stop is used with floating numbers.
RS232 configured controllers
To communicate with the laser, a communication cable is supplied. Each Controller 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 to the Controller 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 configured controllers
The USB configured controllers requires a driver for communication with a computer. The USB driver must be
installed and can be downloaded from the Cobolt website (
). When installed, a virtual COM port will
be created to communicate with the Controller.
To install the USB driver in Windows 7 follow these instructions:
1.
Go to the Control Panel and choose Hardware and Sound.
