Resolving Communications Problems
If communication fails or cannot be established between the F6150 and
the ProTesT software, check the following:
1. Check the RS-232 cable or Ethernet cable.
2. Verify that the CPU circuit board LEDs (D1 & D2) are blinking.
3. Check for conflicts in the COMM PORT of the Computer or laptop
running ProTesT. To do this:
a. Click Control Panel | System Device Manager.
b. Verify that no other device, such as a Palm Pilot, or software is
using the same COMM PORT as ProTesT.
c. Check the Control Panel and Hardware Devices in Windows
95 or Windows 98 for serial device conflicts. If a device
conflict is found, contact your System Administrator.
4. If the communication cable is functioning and no conflicts are found,
replace either the CPU circuit board (page 7-17), Analog I/O circuit
board (page 7-17) or the Communications circuit board (page 7-13).
Error Types
Three types of errors can occur while using the F6000 Instrument:
• Hardware Errors
• Source Errors
• System errors
Hardware Errors
Hardware error messages display on the VFD on the Instrument front
panel. They are often the first sign that something is not functioning
properly in the Instrument.

OTE
Hardware errors must be resolved before further testing can proceed.
Table 6.5 on page 6-12 describes hardware errors and possible solutions.
