Serial TTL To RJ45 Ethernet Module Device USR-TCP232-T2 What is the difference between USR-TCP232-T2 and USR-TCP232-T2 E8 Version ? USR-TCP232-T2 USR-TCP232-T2 is a tiny size serial Ethernet module which can realize data bidirectional transparent transmission between TTL and RJ45 Port. It can also be applied in RS232/ RS485 by level shift circuit.USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency. Function Features: Support DHCP, automatically obtain an IP address and query IP address through serial setting protocol Support DNS function Set parameters through webpage and serial AT command Upgrade firmware via network Auto-MDI/MDIX, RJ45 port with 10/100Mbps Serial port baud rate from 600 bps to 460.8 Kbps, Check bit of None, Odd, Even, Mark and Space Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client Support virtual serial port and provide corresponding software USR-VCOM Heartbeat package mechanism to ensure connection is reliable, put an end to dead link User-defined registration package mechanism, check connection status and use as custom packet header Under TCP Server mode, Client number ranges from 1 to 16; default number is 4 The global unique MAC address bought from IEEE, user can define MAC address Restore factory default Across the gateway, switches, routers Can work in LAN, also can work in the Internet (external network) Provide PC TCP/IP socket programming example such as VB,C++,Delphi, Android and IOS Support customization Application Field of Ethernet Module Industrial data transmission, industrial automation security and protection monitoring, public security Smart home, power control, environmental monitoring, intelligent agriculture Door check on work attendance system,POS system, rice selling system Building automation system, power monitoring, self-service banking system, telecom machine room monitoring Work Mode of Ethernet Module Application of Ethernet Module System Information Processor ARM Flash 32K byte Ethernet Port Number 1 Interface Standard RJ45 Rate 10/100 Mbps, MDI/MDIX, auto switch between cross and direct connection Protection 2KV electromagnetism isolation Network Protocol IP, TCP, UDP, DHCP, DNS, HTTP, ARP, ICMP Buffer Send: 6K bytes, receive: 4K bytes Serial Port Number 1 Interface Standard TTL Data Bits 5, 6, 7, 8 Stop Bit 1, 2 Check Bit None, Even, Odd, Space, Mark Baud Rate 600 bps ~ 460.8 Kbps Flow Control Null Buffer Receive: 800 bytes RS-485 Pull-up and Pull-Down Resistor Null, reserved 485 send-receive control pin Software Virtual Serial(USR-VCOM) Windows 2000 or higher (32 bit/64 bit) Configuration computer set-up software, serial command, built-in webpage, AT command Basic Parameter Size 55 x 22.6 x 23.1 mm Operating Temp. -25~ 75°C Storage Temp. -40 ~ 105°C, 5 ~ 95% RH Input Voltage DC 3.3V/5V Working Current 150mA Power
