	ROBERTSON SKR82 GYRO TO NMEA INTERFACE 909 (R)

INTRODUCTION

The interface converts Robertson SKR82 gyro data to the standard NMEA 0183 format.

Typical applications include interfacing to new equipment such as radar and electronic chart systems.

The interface converts to NMEA directly, requiring no alignment of heading. Options can be generation of stepper, Furuno or Cetrek data. The unit is simple and reliable in operation and designed for unattended operation.

SPECIFICATION

INPUT: NMEA 0183 port. Opto-isolated. Programmed for SKR82 current loop data. Input resistor 3K3. Can share with SKR82 repeater using simple resistive divider network.

Series operation option.
Data as defined as SKR82 9600 baud 4 byte coded inverse.

OUTPUT: NMEA 0183, Standard data $HEHDT,xxx.x,T cr lf. Output rate default is 1 per second and whenever heading changes. Maximum of 10 per second.

5v CMOS limited 5 mA drive.

NMEA 0183, RS422, RS232 compatible.

POWER: 9 to 32 v DC at 200 mA.

HOUSING: Duck Egg Green diecast box 222 x 146 x 55mm.

FEATURES: LEDs on data in and out and bicolour status led.

Power fail and program run watchdog circuit.
All connections removable terminal blocks.
