OPTICAL SYSTEMS DESIGN DATA I/O CONNECTION The OSD1250 Interface Card uses HDB26 connector. The data formats supported are RS232, RS422, RS485, and RS485 4- wire. Signal RS232 Pin RS422 Pin RS485 Pin RS485 4W Pin GND PIN 1 TXD2 RXD2... -
Page 12: Alarm
ALARMS The OSD1250 has an open drain MOSFET rated at 200mA @ 50V max on pin 26 of the DB26 connector. Output at pin26 is 0Ω when unit is powered and ring/bus fiber link present. The output at pin26 becomes high impedance on all units on ring/bus when any fiber link is broken or the unit is off along the ring/bus. -
