The Ethersmart Wildcard™, an expansion module from Mosaic Industries (Newark, CA), enables Web connectivity to the company’s embedded controllers and operator interfaces. The module can be combined with the company’s QCard, a 2 × 2.5" single-board computer, to provide control, communications, and I/O capability. The Ethersmart Wildcard connects with standard Ethernet cables, allowing the QCard to communicate with other computers on a Local Area Network (LAN). The Ethersmart Wildcard implements the SMTP, HTTP, TCP/IP, ICMP, ARP, and DHCP protocols to establish and manage communications. Precoded software allows an application to compose and send e-mail to a specified LAN IP address, open or accept a TCP/IP connection to send and receive binary or ASCII data, and accept connections from a Web browser, serving out dynamic Web pages in response to queries.

The QCard Controller features a 16-MHz 68HC11F1 Motorola microprocessor, 1 MB of memory, communications, analog and digital I/O, and an expansion I/O bus. The QCard is programmable in C, Forth, or Assembly using any PC. Onboard I/O includes eight digital I/O lines with counter/ timer capabilities, eight analog inputs, a synchronous SPI serial interface, and dual RS-232/485 ports. In addition to the Ethernet, the QCard can host a selection of Mosaic’s stackable I/O Wildcards, such as octal 12-bit D/A and 16-bit A/D converters, a 24-bit-resolution analog data acquisition subsystem, CompactFlash card mass memory interface, fast buffered RS-232/485 dual UART, highvoltage/ high-current isolated I/O, and AC or DC solid-state relays.
