Save Program to Drive 1
This function is used to save to an external disk drive if the Model 512 has an external disk drive
connector and an external disk drive is connected. The operation of this function is identical to
the Save Program to Drive 0. (The external disk drive connector was available on earlier
systems; it is no longer available.)
Self Test
This mode is used to test the Model 512. Basically it checks for opens and shorts on the scanner
transmit and receive lines (Scanner Modules). The error type (Open or Short) and the faulty
points are displayed. No test harness should be connected to the unit during Self Test; shorts in
the test harness would be displayed as shorts in the tester.
To perform a Self Test, use the arrow keys to display the mode and then press MENU RUN. If
an error is located, testing stops and the error is displayed. To continue past the error, press
MENU RUN again. During Self Test, "test in progress..." will display. After the test is
complete the display will show "test in progress...passed xxxx rev yyyy." Where xxxx is the
number of points tested and yyyy is the software revision number.
"PROGRAM 1 is free. Save (y/n) ?" or
"PROGRAM 1 in use. Save (y/n) ?"
