SIO TEST 3
The board should b e jumpered to connect the
SIO serial output to the SIO serial input for
this test.
The starting address is 3106 H.
The Sense Switches are used to define any
bits which should not be transmitted as part
of this test.
Switches should be set to a zero
for all bit positions to be transmitted (i.e.,
for seven bits, the MSB is set; for 6 bit, the
two MSBs are set; etc.). If you leave your ter
minal connected to the board while running this
test, do not attempt to type in as this will
generate an error.
The test continously transmits all possible
binary combinations within the pattern and com
pares the received results.
running without error, the Sense Lights will all
be out.
If a PE, OE, or FE occurs, the program will
display 0FF Hex until one of the Sense Switches
is changed.
When a change is made, these errors
are displayed in positions 4, 3, and 2 respec
tively. ' Changing the Sense Switches will cause
the program to continue.
the transmitted value versus received value, the
program will display 0FE Hex.
Sense Switches will cause the value of the trans
mitted character to be displayed in the Sense
Lights.
Changing the Sense Switches a second time will
cause the value of the received character to be
displayed in the front panel lights.
the Sense Switches will also cause the program
to continue with the next value.
