NIKON CORPORATION
Thank you for choosing Nikon Microscopes.
Nikon has recently discovered that Nikon Control Unit DS-L2 for
DIGITAL SIGHT series digital cameras for microscope has two kinds
of program malfunction as summarized below.
Problem 1. The DS-L2 creates image files dated wrong when they are
captured in February of a leap year.
Problem 2. The DS-L2 calibration in the tool menu does not
recognize the correct relay lens magnification and the scale data
given by calibration turns out to be wrong.
Please see below for further details and correction procedures.
Nikon regrets any inconvenience this matter may cause and we
appreciate your continued support of our products.
Details of this problem
1) Problem 1: When you capture images on the DS-L2 during February
1st thru 29th of a leap year (*1) (*2), image files are dated wrong
as follows.
Image file captured on February 1st: It is not dated, or dated
totally different.
Image file captured on February 2nd-29th: The date attached with
the file is one day before.
When folders are created on the DS-L2 during February 1st thru 29th
of a leap year,
the same problem will occur.
The problem is limited to the date and not with image files
themselves.
(Note *1: The upcoming leap year is year 2008.
(Note *2: If the date and time setting of the DS-L2 you have is not
correct,
the same problem will occur during February 1st thru 29th that you
set in the unit.
2) Problem 2: Calibration in the tool menu can't recognize a
correct relay lens magnification as follows.
* When you use the calibration function by inputting object/relay
lens magnification data,
the calibration does not recognize the correct magnification from
the relay lens and
the scale data given by calibration turns out to be wrong.
* When our Nikon Microscope Eclipse 80i/90i (*3), Eclipse LV series
and Multizoom AZ100M
are connected to the DS-L2, the DS-L2's calibration automatically
recognizes object lens magnification and you should be able to get
the scale data only by inputting the relay lens magnification.
However, for the same reason, the scale data after the calibration
turns out to be wrong in this case too.
* The problem does not happen when you use manual calibration mode.
(Note *3): When you connect your camera to the back side of the 90i
DIGITAL IMAGING HEAD "DIH-E/M",
the problem doesn't happen since the magnification of relay lens is
unchangeable.
Object products
1)Problem 1:
* The problem happens with all the units of the DS-L2 which have a
firmware version 1.00 to 3.10 installed.
* If the new firmware version 3.21 has been downloaded from the
Nikon website and has been installed in your DS-L2, the problem
does not happen.
2)Problem 2:
* The problem happens with all the units of the DS-L2 which has a
firmware version 3.10/3.20/3.21 installed,
including the cases where the firmware has been downloaded from the

(Note *4) Procedures on how to check what version firmware is

version is Ver.3.21.
