H 24 V in port Power supply port. To be connected to the DC port, which
is located on the power supply panel, via a Y-cable.
I COM1 port The COM1 port is similar to a conventional, PC-compati-
ble serial port. It is only used for special applications.
J ERR LED The red ERR LED indicates an interferometer error, e.g. a
missing laser signal. When this LED is on, no data acqui
-
sition is possible. See chapter 7 for troubleshooting. The
ERR abbreviation means Error.
FWD LED The yellow FWD LED indicates the current interferometer
mirror movement. When the interferometer mirror moves
forward this yellow LED is on. During the backward move
-
ment of the mirror the LED is off.
Thus, the LED flashes in the rhythm of the interferometer
mirror forward and backward movement. This rhythm
depends on the measurement parameters selected (e.g.
resolution and velocity). When data acquisition actually
takes place the light intensity changes to bright yellow.
The FWD abbreviation means Forward.
TKD LED The green TKD LED indicates that the interferometer mir-
ror is within the data acquisition range. Typically, it flashes
with twice the frequency, and synchronously to the FWD
LED. When data acquisition actually takes place the light
intensity changes to bright green. The TKD abbreviation
means Take Data.
