2 Overview
Thank you for purchasing the Nexus Race Box!
The Nexus Race Box is a great addition to any Nexus instrument system with an FDX
server. Our Race Box can calculate both polar and target boat speed (PBS & TBS), log
your instrument data in both Nexus native binary NXB format and comma separated
values (CSV) format and assist your tactician in making the best start possible. From
time to time, firmware upgrades will be released for the Race Box, and these can easily
be installed. Instructions for upgrading the firmware will be provided with each update.
Information generated by the Race Box is sent to Nexus instruments in accordance with
the Race Box configuration. This will be discussed in detail later in this manual, but in
general, you can send Race Box data to any NX2 or NXR instruments. This includes
the NX2 Multi, the Multi XL, the NXR Multi and the larger NXR instruments.
The Race Box is powered by 12 volts DC, just as the Nexus server is. A standard, DB9
male to DB9 female straight through serial cable connects the Race Box to the Server
data port.
To get the most out of your Race Box, you'll want to have a Nexus buzzer installed on
your FDX server and a Nexus push button connected to the Race Box. The Race Box
will provide the SET STEER and MOB functions you're used to, so you won't need an
additional button. In fact, with the Race Box, all these functions and more are controlled
with a single button. You can reuse the button that is currently connected to your server
if you have one.
The Race Box requires that a standard SD memory card be installed. This card will
have your polar table and your configuration file, both of which are read when the Race
Box starts up. Your log files will also be stored on this card. After your racing, you can
easily remove the card and use any computer with an SD card reader to review your
data.
The Race Box has four, full duplex RS-422 connections for communication with NMEA
0183 and other devices. Future firmware updates will allow the connection of some
peripherals to these connectors. In the initial release, you can connect a NMEA 0183
GPS receiver to the Race Box. The Race Box will accept the RMC sentence up to 5
times per second, for high speed position, COG and COG updates.
The Race Box also has three colored lights which can be seen through the translucent
case. These lights, referred to as the “status lights” or “status LEDs,” will be explained
in detail later in this manual.
Finally, the Race Box has connections for MOB, SET STEER and a buzzer. These are
for future use and currently are left unconnected.
How does it do all that?
