GPIB Hardware Installation Guide and Specifications
Note
By recording the
READY
LED status messages before calling National
Instruments, you can save yourself time, and the Product Support Department can
answer your questions more accurately and efficiently. Do not switch off power to
your GPIB-ENET/1000 before recording the blinking
READY
LED pattern.
READY
LED signaling can report up to 81 different errors. The errors are numbered from
11 to 99 and are reported through sequences of
READY
LED flashes.
Note
There is no zero in any error message. This means that error message numbers
0 to 10, 20, 30, 40, 50, 60, 70, 80, and 90 are not possible.
Step 1. Count the Long Flashes
A three-second interval, during which the
READY
LED is off, separates each repetition of the
sequence. The sequence begins with a series of long one-second flashes—that is, one second red,
one second off. These long flashes represent the digit in the tens column. There can be one to
nine long flashes, which represent digits 1 through 9. For example, one long flash represents the
digit 1 in the tens column, and nine long flashes represent the digit 9 in the tens column.
Step 2. Count the Short Flashes
The long flashes are followed by shorter flashes; each short flash lasts about one-fifth of a
second—that is, one-fifth of a second red, one-fifth of a second off. These short flashes represent
the digit in the ones column. Again, there can be one to nine flashes, which represent the digits
1 through 9. For example, one short flash represents the digit 1 in the ones column, and
nine short flashes represent the digit 9 in the ones column.
Using this method, the
READY
LED flashes the following sequence to represent status
message 11:
<three seconds off> <one long red flash> <one short red flash>
<three seconds off>…
The
READY
LED flashes the following sequence to represent status message 31:
<three seconds off> <three long red flashes> <one short red flash> <three seconds off>…
Step 3. Record Your Status Code Number
When you have computed your error message number, write it down and also note the
ON/OFF state of the
ACT/LINK
LED. Have this information available when calling
National Instruments.
CFG RESET Switch
The Configuration Reset (
CFG RESET
) switch is a recessed switch located beside the power
connector on the rear panel.
