ePAQ-9410 / ePAQ-9420 User’s Guide UG-107114 Communications Ports Copyright 2017 QEI6.3 Port 7 (J3) : Serial/IRIG-B Fiber6.3.1 IntroductionThe IRIG-B Fiber port consists of a 10BaseFL compatible serial fiber optic transmitter andreceiver. The port receives IRIG-B time signals, and can also be software configured for use as ageneric UART serial data channel.The port receives IRIG-B time signals, and via loop config can pass them out to anotherdeivce. IRIG-B time code can be received from many sources: IRIG-B modulated BNC input RS-485 input Fiber IRIG-B input NTP time code received over the TCP/IP network (Possible future enhancement; not ininitial product release).6.3.2 ConnectionsFP Designation : TX and RX , J3Connector Type: Separate Fiber optic Receiver and Transmitter with STconnectors (quarter turn locking).Receiver: Avago HFBR-2412Z.Transmitter: Avago HFBR-1414Z.Wavelength: 820 nmMax Data Rate: 115.2kbps (When used as serial port. Irig data rate is fixed byspecification)
