If Controller Does Not Respond to Pushbuttons
The automated Lasercheck controller is designed to work under external computer control or under control of
the front panel pushbuttons. This is determined by configuration of an internal (user selectable) setup file inside
the control box. When a setup file configured to respond to an external computer through the serial RS232
connector on the back of the control box is active, the system will not respond to the front panel pushbuttons.
It takes about one second for the serial port to take control away from the pushbuttons when a “serial” based
setup file is active. In fact, sometimes the controller may just come up with a “serial” based setup file displayed
when you start the system making it difficult to ever get control of the pushbuttons. The solution is to fairly
rapidly push either of the scroll (> or ^) pushbuttons as the “serial” based setup file appears. You can get the
unit to briefly respond and scroll past a “serial” based setup file if you do it quickly and this will allow you control
of the unit through the pushbuttons so that you can do routine measures, file maintenance, transfers and so on.
