1. General description
The CU601C is a microprocessor based system, which provides hardware
interfaces and commands to and from the cabinet components and laser
bench. There is also a remote box (RB601) that plugs into the front panel
of the CU601C. The remote box allows the user to enter commands on a
keyboard and view responses on an alpha-numeric liquid crystal display
(LCD). The user may also control the CU601C through an RS232 interface
on the front panel.
The interfaces from the rear panel to rack mount are:
• cooling group interlock
• 4 power unit interfaces.
Rear panel to laser bench:
• laser head interlock
• 2 harmonic generators
• shutter
• Q-switch a/b output
• low voltage output (24Vdc).
Other rear panel interfaces:
• ac power input
• auxiliary sync output
• externals
• +24/trig delayed.
Front panel:
• remote box
• RS232
• variable sync output.
The CU601C controls fall into 3 categories -
a) interlock monitoring and crystal heater control
b) external charging and firing control
c) RB601 or RS232 controls which are:
