If the ping test of the host computer’s IP passed, while the ping of the Model 9116 module
failed, check the following possible sources for error:
● Ensure the Model 9116 module’s IP has been assigned (as explained in Section
6.1.2.1) and that the correct IP was used for the ping test.
● Ensure the IP address of the host computer and the Model 9116 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 Model 9116 modules.
6.2 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.
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 9116 with its internal transducers and calibration
manifold.
● 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.
● The module’s calibration valve is not placed in the correct position before executing
the Span calibration command (Calculate & Set Gain). This command will not
automatically shift the valve to the CAL position before taking data (as the Re-zero
calibration command does). The user must manually control the calibration valve
position using the Set Operating Options (‘w’) command if the CAL and CAL REF
inputs are to be used.
