Introduction

The AS00 is intended for use in a marine environment. It provides an easy way to link NMEA 2000 devices to an older NMEA 0183 listener device (e.g., chart plotter or voyage data recorder). It features an NMEA 2000 to NMEA 0183 converter with a wide support of message types.

The AS00 has an NMEA 2000 input and an NMEA 0183 output port. It supports the conversion of most NMEA 2000 PGNs and is compatible with a wide range of NMEA 0183 listener devices on the market.This includes devices using the RS422 (differential terminals) or RS232 (single terminal) communication protocol.

Thanks to its small size it can be easily installed behind instrument panels, making this device the ideal solution for vessels with limited available space for marine instruments, or on boats where multipleconverters are required. It is also recommended for marine electronics engineers or technicians, who require direct access to a vessel’s NMEA 2000 network data, for testing or investigative purposes.

Please refer to the Conversion List chapter for details of supported (and non-supported) conversions.

If you need a NMEA 0183 to NMEA 2000 small size converter, please choose QK-AS01 NMEA 0183 to NMEA 2000 Mini Gateway.

Mounting

The AS00 is aimed at the commercial, leisure and fishing boat markets.

It is not waterproof so should be mounted in a dry place such as behind the instrument panel on a flat surface.

Connecting

Disconnect all power sources before connecting your equipment!

Connecting to the NMEA 2000 network

The AS00 is pre-fitted with a five-core screened cable for the NMEA 2000 connection, fitted with a male micro-fit connector. Simply connect the cable to the NMEA 2000 network backbone or using a T-piece connector.

The main communication channel of an NMEA 2000 network is an NMEA 2000 backbone to which NMEA 2000 devices are connected. The NMEA 2000 backbone must be powered from a stable 12V DC power supply and always requires two termination resistors.

Please note the AS00 is powered by the NMEA 2000 network.

Connecting to a NMEA 0183 Device

The AS00 comes with a 4-way terminal block. Two of these terminals, labelled as ‘OUT+’ and ‘OUT-‘,represent the NMEA 0183 output port and can be used to connect the AS00 to an NMEA 0183 listener device (e.g., a VDR’s or a chart plotter’s NMEA 0183 input). Please ensure the NMEA 0183 listener device is connected to the right terminals, as connecting it to the wrong terminals will damage both the AS00 and the other device.

NMEA 2000 networks operate with a high data rate of 250kbps. To reduce the amount of data loss caused by data overflow when converting data from a high- speed network to a lower speed connection, the AS00’s NMEA 0183 output baud rate is set to 38400bps. Please ensure your NMEA 0183 listener device input’s baud rate can be set to 38400bps, otherwise it will not be able to communicate with and receive data from the AS00 gateway. Please read your listener device’s manual or contact the manufacturer for more details.

Although the AS00’s NMEA 0183 interface is based on the RS422 communication protocol (differential ends), it also supports NMEA0183-RS232 interface devices (single end). The following tables provide the wiring information for each type.

| QK-AS00 terminal| RS422 device terminals
---|---|---
NMEA 0183 Output| NMEA OUT+| NMEA input+ *[¹]
NMEA OUT-| NMEA input-

*[1] Swap NMEA + and NMEA- wires if the connection does not work.

| QK-AS00 terminal| RS422 device terminals
---|---|---
NMEA 0183 Output| NMEA OUT+| GND *[²]
NMEA OUT-| NMEA input
[2] Swap NMEA input and GND / NMEA output and GND wires if the connection does not work.

Configuration

The AS00 is a plug and play device, no initial configuration is required before connecting it to an NMEA0183 device or to the NMEA 2000 network. By default, the AS00’s output baud rate is set to 38.4kbps.As the NMEA 2000 network uses a significantly higher data rate (250kbps), while the default NMEA 0183 port runs at 38.4bps, data overflow on the NMEA 0183 output port cannot be completely avoided.

If there are multiple NMEA 2000 devices connected to the backbone, please be aware of the possibility of data overflow.

NMEA 0183 output sentence format

The AS00 can be helpful for the boat owners or the trained technician to directly access the boat’s NMEA 2000 network data and perform any diagnostic or analytical work accordingly. In this case,viewing raw NMEA 2000 data in PCDIN format might be required. This can be achieved by short connecting the AS00’s GND and SET terminals. Please ensure your device is disconnected from the NMEA 2000 network (powered off) before short connecting / disconnecting the GND and SET terminals.

Conversion Lists

The following tables list the supported NMEA 2000 PGN’s (parameter group numbers) and NMEA 0183 sentences. It is important to check the table to confirm that the AS00 will convert the NMEA 2000 PGNs to the required NMEA 0183 sentences.
