To initiate the VersiPort Analog Input Test for each pin in the DIGITAL IN/OUT port, depress the
corresponding menu number. For example, to test pin 1, depress 1 on the keyboard.
The MRMT11 VersiPort Analog Input Test begins by the PC prompting the user to depress the
space bar to initialize the test. This test indicates whether the threshold value is exceeded. As
long as the value read at the VersiPort is greater than or equal to the threshold value, an
asterisk (*) appears on the screen every quarter second. If the value read at the VersiPort is
less than the threshold value, a dash (-) appears on the screen at quarter second intervals. To
end the test, depress the space bar.
