4.6 Diagnostic
Interface
A RS232 diagnostic interface (J8) is provided on the front panel of the MT4000. This interface is
designed to connect to a PC through a standard RS232 9-pin cable. Through this interface the
operator is able to calibrate analog channels, set or adjust system parameters, download the
complete event log, download analog channel calibration tables, or upload analog channel
calibration tables. TN4000-6 Technical Note, Troubleshooting & Customer Service Guide for
MT4000 will describe calibration procedures, upload analog channel calibration tables, and data
logging function of the 45A0158 Diagnostic Test program.
The following procedures assume that a PC is connected to the HPA diagnostic interface that has
the 45A0158 Diagnostic Test program loaded on to it. These procedures give an outline for
viewing, downloading, and uploading data to the HPA. The diagnostic interface program has
information built into the Help menu to give the operator additional assistance. The Windows cut
& paste functions are enabled on all program tabs except “Calibrate”.
4.6.1 Downloading
Status
1.
On the Diagnostic Interface program click on the “Status” tab (see the figure below).
2.
Click on the “Now” button to refresh the status or check the “Update every” box to
automatically update status.
3.
To save the data to disc, once the status is done downloading, click on the “File”
menu, select “Save” on that menu, then on the Save menu select “Status.” The
diagnostic program will automatically produce a file name, which includes the HPA
serial number, “status”, and today’s date.
4.
The "add to database" box when checked will automatically save the downloads to an
Access 97 or better compatible database. Downloads are stored by HPA ID, Serial
Number and download time. The database can therefore handle multiple HPAs.
Access 2000 can be used for advanced charting and reporting of this data. The file is
stored in the application directory under filename hpa-log.mdb
