Furuno GP-170 - Transmission Interval; Load Requirements as Listener; Data Transmission; Schematic Diagrams

APPENDIX 1 DIGITAL INTERFACE (IEC 61162-1 EDITION 4 (2010-11))
AP-2
Ethernet Input/Output (DUAL mode only)
PFEC (GPasc, GPdst, GPmr2, GPmsk, GPreq, GPrt2, GPtrp, GPalm, GPrai)
Transmission interval
All sentences except ALR and HBT output at the interval selected (00 - 90 s).
Load requirements as listener
Isolation: Photo coupler
Input impedance: 470 ohms
Max. voltage: ±15V
Threshold: 3 mA (in case of connection of FURUNO device talker)
Data transmission
Data is transmitted in serial asynchronous form in accordance with the standard referenced in IEC
61162-1 and IEC 61162-2. The first bit is a start bit and is followed by data bits.
The following parameters are used:
Baud rate: 4800 for IEC61162-1, 38400 for IEC-61162-2
Data bits: 8 (D7 = 0), parity none
Stop bits: 1
IEC61162-1: Edition 4.0 2010-11, Third edition 2007-04
IEC61162-2: First Edition 1998-09
IEC61162-450: Edition 1.0 2011-06
