The QT511 is a new enhanced version of the Quantum Research QWheel chip.
Now any device with serial inputs and outputs can be Ethernet/Internet-enabled for less than $35 (one-off).
Setup for the 1.6 x 2.2in EG-SR-7150MJ is very easy with the configuration software provided.
Three different modes of operation are supported: TCP server, TCP client and UDP.
TCP guarantees data delivery, but UDP doesn't require acknowledgement, so communication can be faster.
Once the TCP client and server have established connection, data can be transparently transmitted bi- directionally.
The EG-SR-7150MJ's IP address can be manually assigned (static IP), or IP, subnet and gateway address can be acquired from the DHCP server automatically.
Serial commands can be hardware- or software-triggered.
Configuration can be done on-site if need be, even without a PC, using a simple serial device (keypad etc).
The EG-SR-7150MJ is based on WIZnet's TCP/IP- offload IC W3150A with Realtek's RTL8201 Ethernet driver chip.
The EG-SR-7150MJ has a built-in Atmel AT89C51RC2 8bit microcontroller with 32Kbyte Flash memory and 32Kbyte SRAM.
EG-SR- 7150MJ offers 10/100Mbit/s auto-sensing on its RJ45 connector.
Protocols supported include TCP, UDP, IP ARP, ICMP, MAC, PPPoE.
Serial signals available are TXD, RXD, RTS, CTS, GND.
RS232 data formats: parity - none, even, odd; 7/8 data bits; flow control: RTS/CTS, XON/XOFF.
The EG-SR-7150MJ needs only 3.3V at 150mA.
The EG-SR-7150MJ-EVB provides a DB-9 connector for quick PC hook-up, CD (configuration program, schematic, manual), a 5V 500mA power adapter and serial and UTP cables.
