the display may be helpful because it prevents front
panel indicators (such as
OPEN
and
CLOSED
) from blinking syn-
chronously with shutter operation—a potential nuisance in certain
laboratory environments.
1.2.5.7 Error code display
As discussed in
§
1.2.2.5, it is possible to display the error code in the
event of a shutter fault by pressing [Shift] [Err Code]. SR470 errors,
for example communications errors, are indicated by the lighted
word “ERROR” to the left of the numeric display. If this enunciator
is lit, [Shift] [Err Code] will display the SR470 error. If the message
is too long to fit on the display, the [
←
] and [
→
] keys can be used to
reveal the whole message.
If there are multiple errors, use the [
] and [
] keys to view the
additional messages. The “ERROR” enunciator will remain lit while
there are still unviewed error messages.
The list of SR470 error codes is in
§
2.6.

Remote interface configuration
The remote interfaces of the SR470, RS-232, GPIB, and Ethernet, can
be configured from the front panel. The user interface for these three
configurations is di
ff
erent from data entry elsewhere on the SR470
in that it is menu driven. Within each configuration, use the [
] and
[
] keys to navigate between menu items (parameters), and the [
←
]
and [
→
] keys to choose between di
ff
erent values or to scroll through
long IP address parameters.
1.2.6.1 RS-232
The SR470 comes standard with an RS-232 communications port
located on the rear panel of the SR470 . For more information about
this port, please see
§
1.3.8.3.
The RS-232 menu can be accessed by pressing [Shift][RS-232]. Use
[
