Abstract

A PCB mountable module includes logic circuitry that translates between serial and wireless communication protocols. Supported standards include I2C, CAN, ProfiBus, SPI, and USB, IP, ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP. Modules can optionally provide security, MILARRS functionality, and web related services such as email alert. The novel modules can be used wherever a device designer wants a plug-in (or “drop-in”) system that obviates the need for independent development and maintenance of wireless capability. Examples include servers, desktop and laptop computers, and even devices such as kitchen appliances with relatively simpler electronics.

Claims

1. A module comprising:

an electronic component board mountable housing that includes a logic circuitry that translates between a serial communication protocol and a wireless communication protocol;

a physical connector for connection to a major surface of an electronic component board; and

an RJ45 connector and an antenna, each of which is electronically coupled to the logic circuitry.

2. The module of claim 1 wherein the housing has a cross-section of an RJ45 connector.

3. The module of claim 1 wherein the physical connector includes pins for attaching an external RJ-45 jack.

4. The module of claim 1 wherein the circuitry is disposed on a single chip.

5. The module of claim 1 wherein the circuitry is split among multiple components.

6. The module of claim 1 further comprising at least 256 Kilobytes of memory that stores an operating system.

7. The module of claim 1 further comprising at least 2 Megabytes of memory that stores at least one web page.

8. The module of claim 1 further comprising a voltage supervisory circuit, and a power feed of no more than 5 Volts.

9. The module of claim 1 wherein the physical connector comprises an array of at least 3 pins.

10. The module of claim 1 wherein the physical connector comprises an array of at least 3 flattened wires.

11. The module of claim 1 further comprising a plurality of general purpose programmable input/output pins (PIO) within the housing.
