3.1 General notes on remote control
The description of the mainframe of the PRO8000 (-4) / PRO800 includes all
instructions of how to prepare and execute the programming of the system via
IEEE 488 computer interface.
Special operation features of a LDC8xxx current module are described here.
(Refer to chapter 2, "Operating the ITC8xxx" starting on page 27)
NOTE
All analog values are read and written in SI units, i.e. A (not mA), W (not
mW) etc. Letters may be written in small or capital letters.
Attention
Before programming a current module first set the limit value of the
laser diode current I
LIM
(hardware limit) for the applied laser diode
with a screwdriver.
The corresponding potentiometer is marked I
LIM
and is situated at the
front of the ITC8xxx module.
The value I
LIM
is constantly measured by the PRO8000 (-4) / PRO800
and can be checked in the sub-menu of the ITC8xxx during setting.
(Refer to chapter 1.5.1, "Hardware limit I
LIM
" on page 13)
