FEATURES
DESCRIPTION
The PTN3500 is a general purpose maintenance and control device.
It features an on-board E
codes or board manufacturing data for read–back by application
software for diagnostic purposes.
The eight quasi bidirectional data pins can be independently
assigned as inputs or outputs to monitor board level status or
activate indicator devices such as LEDs.
The PTN3500 has three address pins allowing up to 8 devices to
share the common two wire I
The PTN3500 supports live insertion to facilitate usage in removable
cards on backplane systems.
