This is a communication gateway that collects information from various devices interface and sends it to a data collector web server for processing and visualization. This specific variant is build to gather information from devices with RS232, but is easy to expand USB and ATA/IDE ports. This module can be used in areas where it is needed to collect data from external peripherals (e.g. measurement equipment, sensor) and to provide it to Ethernet server for further processing. Each device has a unique identifier for identification.
The communication gateway is implemented with 2 circuits, the base board and the daughter board. The daughter board can be modem or Ethernet.
Main bard processor uses a Samsung S3C44B0X. This is an ARM7TDMI core processor with 60Mclock frequency, contains LCD controller and SDRAM controller, 2 x UART, and up to 71 general purpose I/O ports.
MODEM Card uses VI-BRIDGE embedded Modem module, or DAVICOM DM562P, it supports up to 56kbps transmission, compatible with ITU-T V.90, V.34, V.32bis, V.32, V22bis, V.22, V.23, V.21, BELL 212A, 103. It supports data compression and error correction. It is compatible with V.42bis, V.42, MNP Classes 2-4 and MPN 5 protocols.
Ethernet Card (PPPoE) adapts Realtek RTL8019AS Ethernet controller. It is a full-duplex Ethernet controller with PnP function, transceiver speed up to 10Mbit/s with 16KB build-in SRAM. It supports 8/16 data bus.
