special terminator sequences as follows:
1. Y(LF) = CR LF (Two terminators)
2. Y(CR) = LF CR (Two terminators)
3. Y(DEL) = No terminator
NOTE
Most controllers use the CR or LF character to
terminate
their
input
sequences.
Using
a
nonstandard
terminator
may cause the con-
troller to hang up unless special programming is
used.
Programming
Example-Enter
the following
statements
into the HP85 keyboard:
REMOTE 718 (END LINE)
OUTPUT 718; "YtX"
(END LINE)
ENTER 718; t$ (END LINE)
After END LINE is pressed the first time the Model 706 is
placed in the remote mode. After END LINE is pressed the se-
cond time the terminator is changed to the ASCII character
T. After END LINE is pressed the third time, the HP-85 ceases
to operate because it is waiting for the standard terminator
sequence. The HP-85 may be reset by holding down the
SHIFT key and then pressing RESET on the keyboard.
3.5.8 Inputs
1. Set Number of Poles (AI
The letter A is the command to set the Model 706 into one
of the pole configurations
or the matrix mode. There are
three different pole configurations and they are as follows:
A0 = Matrix Mode
Al = l-pole Mode
A2 = 2-pole Mode
A3 or A4 = Cpole Mode
Programming
Example-Enter
the following
statements
into the HP-85 to program the Model 706 into the 4pole
mode.
REMOTE 718 (END LINE)
OUTPUT 718; "A3X"
(END LINE)
When the END LINE key is pressed the second time, the
Model 706 is placed in the 4-pole mode. To verify the Model
706 is now in the Cpole mode, press PRGM, 6 and note the
front panel display. Press ENTER to return to normal display.
Programming
Example-Enter
the following
statements
into the HP85 to program the Model 706 into the matrix
mode.
REMOTE 718 (END LINE)
OUTPUT 718; "AOX" (END LINE)
When the END LINE key is pressed the second time, the
Model 706 is-placed in the matrix mode and the display is as
follows:
This format is explained as follows:
Where:
nnn m 0 or C
nnn is a three digit number displaying the column, card # and
unit #.
m is the row from 1 to 4.
o or c denotes open or closed.
As an example, consider the following display
Where:
004 Denotes unit #l (001 through 050 denotes unit #l).
004 Also, denotes card #l (001 through 005 denotes card
#l).
004 Also, denotes column #4.
2 denotes row #2
c denotes the crosspoint is closed
Therefore, the display 004 2 c means that the crosspoint of
unit #l, card #I, column #4, row #2 is closed. The programm-
ing statement that depicts this crosspoint is as follows:
OUTPUT 718; "COO42X" (END LINE)
To display the previously
programmed crosspoint on the
Model 706s display enter the following
statement into the
HP-85.
OUTPUT 718; "B0042X"
(END LINE)
Now, return the Model 706 to the 2-pole mode by entering
the following statement into the HP85 keyboard:
OUTPUT 718; "A2X"
(END LINE)
The l-pole mode is available only on the Model 7056 scanner
card. On the card, relay Kill
is the output relay for the even
channels and relay K112 is the output relay for the odd chan-
nels. These relays close when the appropriate channel relays
close. In the l-pole mode, each channel relay on the 7056
scanner card controls two channels. This is because they are
the same relay. For example, jf the channel 1 relay is closed,
then the channel 2 relay is also closed because they are the
same relay. The closed channels do not reach the output
unless the appropriate output relay is closed.
In some situations this may close channels that are not pro-
grammed as closed. For example, if channels 1 and 4 are pro-
grammed as closed, then because of the scanner card's ar-
chitecture,
channels 2 and 3 are also closed. Refer to the
following chart.
