If the ping test of the host computer’s IP passed, while the ping of the NetScanner ™ System module
failed, check the following possible sources for error:
! Ensure the NetScanner ™ System module’s IP has been assigned (as explained in
Section 6.2.2.1) and that the correct IP was used for the ping test.
! Ensure the IP address of the host computer and the NetScanner ™ System module are
not duplicated on the network.
! Ensure the link LEDs are active on the scanner and the Ethernet hub or switch to
which it is attached. Also ensure the link LEDs are active on the host computer’s
Ethernet adapter and the hub or switch to which it is attached.
! Ensure the Ethernet adapter card installed in the host is properly configured without
conflict. In Windows
® 95 this can be verified by entering the CONTROL PANEL
under SETTINGS. Under CONTROL PANEL, select the SYSTEM icon. When
the DEVICE MANAGER tab is selected, a list of all installed hardware devices will
be displayed. Any possible hardware conflicts will be marked in this list with a
yellow warning symbol next to the device in question.
! Ensure the Ethernet adapter is configured for 10 Mbit/Sec. Many adapters are
capable of higher speeds that are not compatible with the NetScanner
™ System
modules.

Zero and Gain Calibration Troubleshooting
Incorrect pneumatic setup or incorrect command usage when executing a module’s Re-zero or Span
calibration command (see ‘Z’, ‘h’, and ‘C’ commands in Chapter 3) can result in unexpected
module operation. A common source of errors during these operations is incorrect control of the
module’s internal calibration valve and pneumatic inputs (9016) or their external
pneumatic/hydraulic equivalents (9021/9022).
Pressure connections are described in Chapter 2 while details of calibration procedures are
described throughout Chapter 4. Some common errors and problems are listed below. These
common problems apply primarily to Model 9016 with its internal transducers and calibration
manifold. However, similar symptoms may be encountered with external pneumatic/hydraulic
calibration equipment connected to a model 9021/9022’s all-media transducers.
! The module’s supply air input is either not attached or does not provide enough
pressure (less than 65 psig) to shift the calibration valve. This results in the
calibration valve remaining in its current position even though module commands
have requested movement of the valve.
