Pin not listed in the above sheet is not used by evaluation board 2. Recommend to make the shield of DB9 connect to ground Power On board DC JACK with internal size : 2.0mm,，power circuit support pole protection， input voltage arrange:7.5V~12V。adjustable power chips are LM2596 DC-DC and LM1117-3.3V LDO from SIPEX。 Selectable Channel Switch The Evaluation board provide 8bits DIP16/8 switch to select neport1 or neport2 to communicate with external rs232 interface. Push switch to ON will enable the corresponding signal. Attention： 1. User just can enable one group of this 8bits switch,(group 1:one:1-4 , Group 2:5-8), or Evaluation board can’t communicate with external rs232 devices 2. When all of 8bits switch are disconnected or one group are disconnect but no neport on the other group, such setting may cause no signal output to rs232 8Pin/2.0 pitch header The Evaluation board provides 8pins pitch header for OEM/ODM customized development, and this pitch header can make neport signals connect to user’s MCU/DSP efficiently to debug or testing according to the real application Attention： Should disconnect the extern rs232 interface to avoid effect testing result Buttons The Evaluation Board integrates three buttons used as reset / defaulting setting 16 NePort Summary Embedded Seial-IP series NePort –L Series NePort-R Series NePort Series NePort-EN Series Single port series LX SX EXH LX RX -485 Memory and Speed Core and System Serial Interfaces RX -485 SX -485 EXH ESX -485 Flash 128k 128k 256k 256k 512k 512k 512k 512k 512k Code/Boot(KB) /32 /32 /32 /32 /32 /32 /32 /32 /32 SRAM(KB) 80/128 80/128 128 128 256 256 256 256 256 Speed (MIPS) 55 55 55 55 55 55 60 60 60 ARM7TDMI Y Y Y Y Y Y Y Y Y Multi-T RTOS Y Y Y Y Y Y Y Y Y Ethernet Speed (M) 10/100 10/100 10/100 10/100 10/100 10/100 10/100 10/100 10/100 Y Y Y Y Y Y Y Y Y Y Y Uart RS232 Y RS485/422 Y Y Max-Baudrate(bps) 115200 115200 460800 460800 460800 460800 921600 921600 921600 Serial port Number 1 1 1 1 1 1 1/2/3 1/2/3 1/2/3 Programmable I/O PIO Number -- 2 -- 2 -- -- -- 2 2 Protocol stacks ARP/IP/ICMP/DHCP Y Y Y Y Y Y Y Y Y TFTP Y Y Y Y Y Y Y Y Y SNTP -- -- -- -- Y Y -- Y Y --Y Y Y Y Y Y Y Y /BOOTP/TCP/UDP Http Server (web customized) Telnet Server Y(*) Y(*) Y Y Y Y Y Y Y DNS Y(*) Y(*) Y(*) Y(*) Y Y Y Y Y Smtp (Email Trigger) -- -- -- -- Y(*) Y(*) -- Y Y PPP/PPPOE -- -- -- -- -- Y(*) -- -- Y Advanced SSH -- -- -- -- -- -- -- -- Y encryption SSL/TLS -- -- -- -- -- -- -- -- Y protocols Https -- -- -- -- -- -- -- -- Y Smtps -- -- -- -- -- -- -- -- Y Encryption AES -- -- -- -- -- -- -- -- Y Arithmetic DES/Triple-DES -- -- -- -- -- -- -- -- Y RC4 -- -- -- -- -- -- -- -- Y MD5 -- -- -- -- -- -- -- -- Y Power suppler(V) 3.3 3.3 3.3 3.3 3.3 3.3 3.3 3.3 3.3 I/O Tolerant(V) 5 5 5 5 5 5 5 5 5 PowerConsumption 10Base-T Activity 165 165 165 165 165 165 165 165 165 (mA) 100Base-T Activity 155 155 155 155 155 155 155 155 155 C,I C,I C,I C,I C,I C,I C,I C,I C,I RJ45 RJ45 RJ45 RJ45 RJ45 RJ45 RJ45 RJ45 RJ45 Low Low Cost Cost Analog parameters Operating temperature arrange C=0- +75°C Package Option I = - 40 - +85°C (RJ45) 17 More details by: http://www.conextop.com/products/embeddedsolution/wiredmodules/index.htm For details contact your local Conextop representative or Conextop directly: call OEM sales support at 86-755-26505615 More details about NePort at http://www.conextop.com © Conextop Technologies –November 2003 - All rights reserved The Conextop corporate logo is a registered trademark of Conextop Technology.
