Note: Each of the three DIP switches works identically.
SW1 controls code output on rear panel BNC J3a or J3d.
SW2 controls code output on rear panel BNC J3b or J3e.
SW3 controls code output on rear panel BNC J3c or J3f.
The modulation ratio and amplitude can be individually adjusted for each of the three channels
as follows:
