4.7 Diagnostic
Interface
A RS232 diagnostic interface (J4) is provided on the MT4400. This interface is designed to
connect to a PC through a MS3116-10-6S connector. 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.
TN4400-6 – Technical Note, Troubleshooting & Customer Service Guide for MT4400, will
describe calibration procedures; upload analog channel calibration tables, and data logging
function of the 45A0158 or 45A0189(Multi-Band HPAs) 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 onto 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 and paste functions are enabled on all program tabs except “Calibrate.”
4.7.1 Downloading
Status
1.
On the Diagnostic Interface program click on the “Status” tab (see the following figure).
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.
