10. Options

GPIB Interface
This option may be substituted for the RS232 interface. This option provides all of the
function control of the RS232 interface with the addition of SRQ functions. All
commands can be found in section 9. Bus Remote Interface GPIB/RS-232 of this
manual.
Printer Port Option
This option allows the instrument to generate hardcopy printout of the test results.
The printout can be configured to print automatically with each test, or manually by
pressing a front panel key. There is also capability to enter a serial number identifier
to each test that increments automatically after each test is performed. The test can
be further configured to print only results from tests that have failed or to print all test
results from every test performed.
The Printer Port is a parallel interface and should be compatible with most parallel
printers. The printer port output uses simple ASCII characters and control codes.
Simply connect the printer to the instrument and configure the printer output using the
Setup menu. The following sections describe the setup procedures for configuring the
printer output.
Auto Print
Please press the SETUP key to enter the Setup menu. Press the SETUP key four
more times to scroll to the Auto Print selection the screen will show:
AUTO Print = ON
<ENTER> to Select
To configure Autoprinting press the ENTER key to change the selection. When Auto
Print = ON the printer output will generate data every time the test has completed, and
will also enable two other menus to configure the Print Mode and the Print Number.
When Auto Print = OFF the user must press the LOCAL/PRN key on the lower left
section of the keypad to generate printer output.
When the EXIT/PRINT key is pressed after the test is completed the printer output will
be a duplicate of the front panel LCD test results. This key should only be used to
retrieve test results after the test has been completed. Although the output will print
the LCD screen during a test, the actual elapsed test time may be effected when
printing while the test is active.
Print Mode
Please press the SETUP key. This menu selection works in conjunction with Auto
Print. The Print Mode screen appears as follows:
Print Mode = All
<ENTER> to Select
AUTO Print = OFF
<ENTER> to Select
Print Mode = Fail
<ENTER> to Select
