EMBER & RAYMARINE LIMITED - COMPANY CONFIDENTIAL 1 Purpose The purpose of this document is to outline Raymarine’s Embedded Wireless Networking Technology. Raymarine are developing four products. They are: 1. BASE 2. S1000 (Autopilot) 3. S100 (Autopilot Controller) 4. SMART CONTROLLER As such these developments can be grouped by into two distinct, and quite different wireless categories. These are: 1. GW - Gateway 2.

For example, from Standby to Auto and vice versa, course changes, etc… It also displays the current Autopilot status. 2.4 Smart Controller The Smart Controller is a Handheld Controller. It will be used in conjunction with the Base Its function is to control a wired Autopilot as well as displaying vessel data that is available on the wired system to which the Base is attached.

Host Processor RX TX Network Processor RF Transceiver SPI EM2420 CONTROL #RESET Raydio Communication Module The Raydio Communication Module (RCM) is based upon Ember’s EM2420 2.

EMBER & RAYMARINE LIMITED - COMPANY CONFIDENTIAL 3.3 Application The application of this solution follows the rules below. 3.3.1 Rule 1 – Data on Request This RF system is not a broadcast system. Data must be requested using the PID request mechanism for the following reasons: 1. Reduced power consumption 2. Reduced on-air time 3.

EMBER & RAYMARINE LIMITED - COMPANY CONFIDENTIAL 3.4 Gateway (GW) The GW is an always-powered device, which will serve requests initiated by Handheld Controllers. This design uses PCB mounted antenna. Its role is to interact with the SeaTalk bus caching data locally, in order to speed up remote transactions. Since the GW is always powered it will be used as a relay / routing device. The embedded software running on the network processor of the GW performs the following functions: 1.

EMBER & RAYMARINE LIMITED - COMPANY CONFIDENTIAL 3.5 Handheld Controller (HC) The HC is a highly power conscious device which will be asleep most of the time in order to preserve power. This design uses an inverted ‘F’ tracked antenna. It will initiate communication on the network and stay awake long enough to hear responses. It will primarily perform ‘set and get’ operations on the gateway to which it is bound.
PAGE 11
EMBER & RAYMARINE LIMITED - COMPANY CONFIDENTIAL In order to further minimize power consumption, the network processor will be called upon, using specially formed commands to execute repetitive tasks, for the host. This will allow the host to stay asleep, while the network processor wakes and performs the tasks, the host will be notified of task results as well as if an error occurs. D619SP06 Issue 1.
