The UGI-417 is an Analog/Digital con-
verter/interface. It can convert the analog
output of Gyro Compass and Log to data
output. The output sentence IEC61162-
1/2can be used for AIS, VDR and IBS. It
fullmeets the requirements of IMO and
IEC61162-1/2.
Power Supply: 18-36 VDC
Output Ports: 2 X RS422, 1 X RS232

Universal Gyro Repeater
The NMEA Buffer module is the best
solution for buffering weak NMEA
sources, allowing NMEA devices to be
driven, such as chart plotters, radars,
and/or an on-board PC/ Laptop.
NMEA Buffer
For ship’s bridge integration, VDR
and S-VDR, there is a need to inter-
face various analogue sensors from
various systems to standard IEC
61162-1/NMEA messages. The
A8N Converter converts up to 8
analog inputs to RS/485/422
NMEA outputs.
Model A8N
NMEA Converter
This NMEA Multiplexer/Combiner
allows connection of up to five
NMEA (National Marine Electron-
ics Association) inputs, and multi-
plexes/combines them to its two
fully isolated NMEA outputs.
NMEA Multiplexer
Universal NMEA Converter is a
"Multi Analog Signal to NMEA
-0183 (IEC-61162-1) Convert-
er" for most kinds of Gyrocom-
pass, Anemometer, Speed Log,
Rudder. The Universal NMEA Converter is useful for
interfacing between old navigation equipment
and VDR, AIS, ECDIS.
Universal NMEA Converter
The NMEA Buffer/Isolator has 1 NMEA
signal input port and 2 NMEA output
ports. Input ports, Output ports and In-
put power are fully isolated with each oth-
ers. This NMEA Buffer can receive any
type of serial data such as RS-422
(NMEA), RS-232, 5V TTL signal for input, and has protection
circuits such as high voltage protection.
NMEA Buffer/Isolator
The NMEA Combiner
(NMEA Multiplexer) combines
up to 8 NMEA-0183
input data and let out it
through 2 NMEA-0183 output ports and 1 RS-232
port. This is very useful for any equipment such ECDIS and
VDR required receiving various NMEA-0183 data from
many devices (multiple talkers – single or multiple listeners
environment).
NMEA Combiner (Multiplexer)
The NMEA Autoswitch from allows
the data from up to four NMEA
(National Marine Electronics Associa-
tion) input devices to be switched to a
single NMEA output, by determining
the highest priority device with good
data.
