9. Channel Save/Recall (I) and (Z}
The letter I is the command to save the present relay set up
or recall the stored relay set up. Refer to paragraphs 26.5
and 2.6.6 (front panel Programs 4 and 5) for more informa-
tion concerning saving and recalling relay set ups. The for-
mat for the save/recall command is as follows:
II, 12, 13, I4 and 15 - Save the present relay set up.
Zi , 22, 23, 24 and 25 - Recall the stored relay set up.
Programming Example
- Enter the following statements into
the HP-85 to program the Model 705 to save the present relay
set up.
REMOTE 717 (END LINE)
OUTPUT 717; "11X" (END LINE)
When END LINE is pressed the second time, the Model 705
saves the present relay set up. To recall the stored relay set up
enter the following statements into the HP-85
REMOTE 717 (END LINE)
OUTPUT 717; "Zl X" (END LINE)
When END LINE is pressed the second time, the Model 705
recalls the stored relay set up.
Programming Example
- Use the following program to store a
relay set up of channels 1 through 5 with the programmed first
channel being channel 1, and the programmed last channel
being channel 5. The odd channels are programmed closed and
the even channels are programmed open. Type the following pro-
gram into the HP-85:

Use the following programming example to recall and display the
saved relay set up.
PROGRAM COMMENTS
Output 717; "Zlx" (END LINE) Recalls saved relay set up,
This program and the previous nine step program saved and
recalled one relay set up. The Model 705 is capable of saving
and recalling five set ups. The commands to save and recall the
relay set ups are as follows:
I1 saves a set up and Zl recalls the II set up.
12 saves a set up and 22 recalls the I2 set up.
13 saves a set up and 23 recalls the I3 set up.
I4 saves a set up and 24 recalls the I4 set up.
I5 saves a set up and
25
recalls the I5 set up.
It's possible to save a relay set up in any of the I commands with-
out having any of the other save commands programmed to save
a set up. For example, 12 can save a set up without having a set
up saved by II, 13, I4 or 15.
10. ROM and LEDTest (J)
The letter J is the command that programs the Model 705 to
go through many of the testing routines that are automati-
cally performed upon power-up. When the self test com-
mand is sent, the following actions are performed:
1. ROMTest
2. LED Test (All front panel LEDs turn on for a short period
of time.)
3. If the tests did not find anything wrong, then the self test
(J) byte in the status word is set to one. If the test failed
then the self test byte (J) is set to two.
The self test command is implemented with the following
command sequence:
OUTPUT 717; "JOX" (END LINE)
NOTES
1.
Other operating parameters are not affected by the JO
command.
2. RAM is not tested by the JO command but is tested upon
'power-up.
11, EOI (End or Identify) (K)
The letter K is the command that programs the Model 705 to
either send or not send EOI on the last byte out on a multi-
ple byte sequence. EOI response of the instrument may be
programmed as follows:
KO - Send EOI during last byte.
Kl - Send no EOI.
Upon power-up, or after receiving an SDC or DCL, the
Model 705 will be in the KO mode.
Programming Example
-The EOI will be suppressed with the
following statement sequence:
REMOTE 717 (END LINE)
OUTPUT 717; "Ki X" (END LINE)
Note that the HP-85 does not rely on EOI to mark the end of the
data transmission. Some controllers, however, may require that
EOI be present at the end of transmission.
