Ethernet to 4-Serial (RS485)

Introduction

This project is created because i had a need for a Ethernet to RS485 converter, a lot of my other projects
has a RS485 communication line, to make these devices easy accessible to all devices on the WAN.
The board has 4 individual RS485 lines, which are used to create a brigde to a unique UDP port,
the baudrate, UDP ports and WINS name can freely be changed via the onboard Serial port or via Telnet.


Features:
- Power supply DC: 8 - 35 VDC.
- ATMega128 16MHz, 48KB SRAM.
- 8 KB Seriel EEPROM.
- 10Mb Ethernet (RTL8019AS).

- Temperature sensore (LM75).
- 1 x RS232 (Console).
- 4 x RS485. (RX/TX LED, and RTS enable pr. line)
- 1 x Boot LED, 1 x Status LED.
