Troubleshooting FAQs
9
1. Wrong COM port. Try all four COM ports even though
you’re sure that your mouse is on COM 1.
2. No power to the Probe Pilot (see Q1).
3. Desktop Systems External connector not connected to
the COM port internally.
4. Laptop Systems external COM connector disabled (Ir
Port Override?). Use your PC’s CMOS setup program to
enable the COM port.
5. COM port IRQ reassigned for DOS program, control
panel not updated.
6. Multiple mouse drivers in system.ini.
7. Third-party serial port “enhancers” not conforming to
windows API.
Q3: I’ve got the IDLE message but when I click on Run, the
Silicon Explorer window flashes an error message and
returns to IDLE.
A: If the target power is incapable of supplying the necessary
current, then the Silicon Explorer window resets and returns
to IDLE. Many current-limiting supplies will trip when set
too close to the operating current.
Q4: The Timing Instrument acquires data and then indicates
errors on read-back?
A: The Timing Instrument bursts data back in blocks at high
speeds, with built-in retry for a bad block (both checksum
and byte count are used). Some third-party serial programs
block all interrupts forcing the analyzer into a retry loop.
Some laptops power down the UART and drop a few
characters. Try disabling “Power Saving” in the CMOS setup
menu.
Q5: When the Silicon Explorer window is open, my other
Windows programs run slow?
