1.2 PHOTO DETECTOR CONNECTORS
1.2.1 DB-15 “intelligent” connector
The DB-15 male "intelligent" connector contains an EEPROM (Erasable Electrical Programmable
Read-Only Memory) that stores information such as the model of the detector, the calibration
sensitivity of the available spectral range with or without attenuator and the applicable scales for
that specific PH and PE Series head. Wavelengths are not available where the sensor physical
properties don’t allow it.
The Gentec-eo monitors use the data in this connector to adjust their characteristics automatically
to the power sensor being connected. No calibration procedure is required when installing the
power heads, allowing for faster set-up.
