The entire staining and cover slipping part of the iSaCS is controlled
through a USB cable by the PC, different from the scanner part. The staining
and cover slipping part is divided into several control electronics, and
addresses are used to distinguish the data stream for the controllers.
The addresses are programmed into the unit, so each unit is unique in
the system. Several controllers are from the same construction.
Wire

Power supply
The power supply
of the main control board is realized by the ±24V and the ±12V line; supplied
directly from the power tower’s power supply TDK Lambda through the connector
“Power, Main electronics”.

Local
control
The shown electronics board is used to control the
· transporter
· stain applicator
· cover slipping
· wash - rinse
The board exists 4x in the staining and cover slipping units;
differences are given in the address of the board and connected units; the
board itself is identical; the firmware also.
Remark
Because the address is different for each board, an interchange of the
board between the named units without address modifying is impossible!
