IEEE-488 PROGRAMMING
Not In Remote Error
A not in remote error will occur if the instrument
receives
a device-dependent
command
and the REN (Remote
Enable) line is false. In this instance, the following
error
message will be displayed
on the front panel:
NOT IN REMOTE
The error condition
can be corrected by placing the REN
line true before attempting
to program the instrument.

Example-To
demonstrate
the NO
REMOTE error message, type in the following
lines:
Note that the NOT IN REMOTE error message is briefly
displayed when the second statement above is cxccuted.
Model 8573 Programming
Example-Enter
the statements
below to demonstrate
the NO REMOTE error message:
Note that the NOT IN REIMOTE error message is displayed
when the second statement above is executed
IDDC
(Illegal
Device-Dependent
Command)
Error
An IDDC error occurs when the unit receives an invalid
command over the bus. For example, the command string
ElX includes an illegal command because the letter E is
not part of the instrument's programming
language. When
an illegal command is received, the instrument
will brief-
ly display the following
error message:
IDDC
To correct the error condition,
send only valid commands.
Refer to paragraph 4.9 for device-dependent
command
programming
details.

Example-To

an IDDC
Note that the IDDC error message is bristly
displayed
when the second statement above is cxccutrd.
Note that the IDDC error message is briefly
displayed
when the second statement above is executed
IDDCO
(Illegal
Device-Dependent
Command
Option
Error)
Sending the instrument
a legal command with ',n illegal
option that cannot be automatically
scaled within
bounds
will result in the following
front panel cuor message:
IDDCO
For example, the command Y65X has .m illegal option (hi)
that is not part of the instrument's
programming
language
Thus, although
the command (K) itself is v.~lid, the op-
tion (9) is not, and the IDDCO error will result.
To corrwt this error condition,
use only valid ~omm~md
options,
as discussed in paragraph 4.9.
NOTE
Programming
channel 2 (C2X) with no ch.mncl 2
module will result in an IDDCO c'rror.
HP-85 Programming
Example-Dcmonstratc
an IDDCO
error with the following
statements:
REP,I(ITE 7M'i
,:,,m,TF'l.IT 7W-1 : i . yt,:;;::,,: . 1
Note that the IDDCO error message is briefly displayed
when the second statement above is executed.
