Troubleshooting FAQs

Q1: I've connected Silicon Explorer II and the window display reads
N/C. Why?
A: Look on the top of the Silicon Explorer II for the flashing yellow
"heartbeat." If it isn't flashing make sure you have properly
connected an adequate power supply.
Q2: It's flashing but still N/C. Why?
A: There are a number of things that prevent you from establishing
communication. The following are the most common:
• Wrong COM port. Try all four COM ports, even if you are sure
that your mouse is on COM 1.
• No power to Silicon Explorer II (see Q1).
• Desktop Systems External connector not connected to the COM
port internally.
• Laptop systems external COM connector disabled (Ir Port
Override?). Use your PC's CMOS setup program to enable the
COM port.
• COM port IRQ reassigned for DOS program, control panel not
updated.
• Multiple mouse drivers in system.ini.
• Third-party serial port "enhancers" do not conform to windows
API.
Q3: I've got the IDLE message, but when I click on Run, the Silicon
Explorer II window flashes an error message and returns to IDLE.
Why?
A: If the target power is incapable of supplying the necessary current,
then Silicon Explorer II resets and returns to IDLE. Many current-
limiting supplies will trip when set too close to the operating
current.
Q4: The Analyze module acquires data and then indicates errors on
read-back. Why?
