1. Set Number of Poles (A)
The letter A is the command
to set the Model 705 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
A2 = 2-pole
A3 or A4 = 4-pole
Programming Example
-
Enter the following
statements
into
the HP-85 to program the Model 705 into the 4-pole mode.
REMOTE
717 (END LINE)
OUTPUT 717; "A3X" (END LINE)
When END LINE is pressed
the second time, the Model
705
goes into the 4-pole
mode. To verify the Model
705 is pro-
grammed
into the 4-pole mode, press PRGM, 6 and note the
front panel display.
Once the mainframe
has been programmed
into the matrix mode
the display uses the following format:
nn m 0 or C
where:
nn -
is a two digit number displaying
the column (five columns
per card, two cards per unit, five daisy chained units maximum).
m -
is the row from 1 to 4.
0 or C -
denotes open or closed.
For example:
Which means:
1 st unit (l-l 0 = unit one)
1 st card (1-5 = first card)
4th column
2nd row
closed
Programming Example
-
Enter the following
statements
into
the HP-85 to program the Model 705 to the first unit, first card,
fourth column, second row, and close this channel.
REMOTE 717 (END LINE)
OUTPUT 717; "CO42X" (END LINE)
To display
the previously
programmed
channel
on the main-
frame's display enter the following statement
into the HP-85.
OUTPUT 717; "BO42X" (END LINE)
2. Display Channel (B)
The letter B is the command
to program the Model 705 to
display a particular channel. The format for the display chan-
nel command
is as follows:
Bnnn
where
B = Display Channel Command
n = Number of Channel
Programming Example
-
Enter the following
statements
into
the HP-85 to program the Model 705 to display channel 7.
REMOTE 717 (END LINE)
OUTPUT 717; "B7X" (END LINE)
The number of channels
for a particular
configuration
is deter-
mined by the number of poles, and Model 705's daisy chained
together. If the channel specified in the statement
is greater than
the programmed
last channel, the Model 705 gives an IDDCO
and then returns to the previously
displayed
channel. Take note
of the front panel display upon pressing END LINE the second
time. Channel 7 should be displayed.
3. Close Channel (C)
The letter C is the command to close a particular
channel.
The format for the close channel command
is as follows:
Cnnn
where
C = Close Channel command
n = Number of Channel
Programming Example
-
Enter the following
statements
into
the HP-85 to program the Model 705 to close channel 7.
REMOTE 717 (END LINE)
OUTPUT 717; "C7X" (END LINE)
Take note of the front panel display upon pressing END LINE the
second time, Channel 7 should be closed.
NOTE
The number of channels for a particular configura-
tion is determined
by the number
of poles, and
Model 705's daisy chained together. If the channel
specified in the statement
is greater than the pro-
grammed
last channel,
the Model
705 gives an
IDDCO and returns to the previous displayed chan-
nel.
4. Display Mode (D)
The letter D is the command
to set a particular
display
mode. There are five display modes and they are as follows:
DO = Display Channel
Dl = Display Interval Time
D2 = Display Time
D3 = Display Date
D4 = Display Message
Programming Example
-
Enter the following
statements
into
the HP-85 to display the date.
REMOTE 717 (END LINE)
OUTPUT 717; "D3X" (END LINE)
When END LINE is pressed the second time, the Model 705 dis-
plays the date.
5. Set Date Format (E)
The letter E is the command
to program the Model 705 to
set the date format for american
date format or the interna-
tional date format. The two formats are as follows:
EO = American Date Format: mm.dd
El = International
Date Format: dd.mm
Programming Example
-
Enter the following
statements
into
the HP-85 to set the date format for the international
date format.
REMOTE 717 (END LINE)
OUTPUT 717; "ElX"
(END LINE)
When END LINE is pressed the second time, the Model 705 is
programmed
for the international
date format.
