SmartScan SBI and Processing Module Connections
The SBI has a two way screw terminal for connecting 9-32 VDC power. The Positive terminal is closest to
the board corner. The SBI generates all it's required voltages from this input and also outputs 5V on pins B3
and B29 of the PC104 bus connector for powering connected devices such as the processing Module.
Heat Sinking
T
he SBI's laser is mounted on a heat sink block, this should be fastened to a metallic structure that can
dissipate heat, such as an enclosure body or chassis. The heat sink block has 3 off M2 x 4 mm threaded
holes on a 10 mm pitch for this purpose. The laser case temperature (which can be reported by software)
should be kept below 75 °C under all operating conditions so as not to degrade laser performance.
If the SBI is used 'open frame' at room temperature then the heat sink block alone should be sufficient.
