Computer control SDG II

The SDG II can be controlled with a standard RS-232 serial port. I made a standard 9-pin D-sub male/female extension cable for hookup. Only three pins are used for serial communications:
2SDG II trnsmit data, computer receive data
3SDG receive data, computer transmit data

Through the serial communication, I can control the Hurricane laser repetition rate acuurately. By sending command "set:rate 0127", the rate was fixed at 507Hz/127=3.99Hz.
