LANbridge

LANbridge is a device for creating the Ockam UDP broadcast over your local Ethernet without the need for a PC. Heretofore, the UDP broadcast was generated by the OckamSoft 4 driver, meaning that having an onboard PC was a prerequesite for using Eye. With LANbridge, a PC is no longer required. LANbridge comes in both wired (RJ-45) and wireless (802.11B/G) versions.

LANbridge enables ethernet communications via the UDP broadcast from any Ockam processor. With a wireless router attached, LANbridge allows wireless PDA access to Ockam data (e.g. OckamSoft Eye) without an onboard PC.

The UDP broadcast can be used directly by OckamSoft, Expedition and Nobeltec onboard software, bypassing the complications inherent in RS-232 serial communications and its abandonment by the Windows platform.

For boats without a LAN infrastructure, the RS232 interface provides equivalent functionality.

The LANbridge reproduces the Ockam display and NMEA channels over Ethernet. Received commands are transferred to the Ockam keyboard channel.

The UDP broadcast protocol allows any number of PCs and/or wireless devices to receive Ockam data and send commands without interfering with each other.
