The Ethernet Media Converter, provides a cost effective plug-and-play solution for long-range Ethernet extensions and added benefit of auto-negotiation, making it the perfect choice when planning future upgrades of networks. The Ethernet Fiber converters are ultra-miniature in size and feature a shielded RJ45 Ethernet jack, SC/ST/FC style fiber-optic connections. Built-in auto-sensing capabilities enable full or half-duplex Ethernet operation with no configuration required.
This is a serial rs485&rs232 to Ethernet server, used for data transparent transmission. USR-TCP232-410S is a dual serial server, which supports rs232 & rs485 working at the same time. It is based on Cortex-M4 solution And the internal of the serial server integrates TCP/IP protocol stack.Besides, USR-TCP232-410S has the function of terminal power supply.Modbus to Ethernet Converters Feature

TCW122B-WD is an Ethernet controller, specially designed for IP watchdog monitoring. It controls the functionality of a device or a network by transmitting or receiving respectively ICMP echo request or ICMP echo reply. If there is no ICMP echo (ping) for certain time, the appropriate relay is activated and this can restart the monitored device or network switch.
TCW122B-WD has 2 digital and 2 analog inputs, 2 relay outputs and 1-Wire interface and it also can be used for general monitoring and control of environmental monitoring of server rooms. For every of monitored parameters – temperature, humidity, analog voltage and status of digital input, SNMP trap can be sent, if it goes outside of previously set-up range. The relays can be activated remotely (WEB and/or SNMP) or automatically from presence/absence of ping (ICMP echo request or echo replay).Password protected web based configuration and control;
• 1-Wire interface for up to 2 temperature (TST1XX) or temperature/humidity (TSH2xx) sensors;
• 2 relay outputs with NO and NC contacts;
• 2 analog inputs with 0 to 60VDC range;
• 2 digital inputa with “dry contact” or “logic level” mode;
• SNMP v.1 support;
• SNMP trap messages sending under certain conditions;
• VLAN and MAC address filtering;
• Remote FTP firmware update
The device has all necessary functionality to solve the problems of internet service providers like:
• IP watchdog monitoring of small and medium networks;
• Monitoring of temperature and humidity in server rooms;
• Control and management of ISP networks;
• Remote control of electric devices;
4G Modem RS232/RS485 Serial to 4G Network
G780 is a 4G DTU, support FDD-LTE, TD-LTE 4G high speed access, support WCDMA, TD-SCDMA and GSM as well. Perfect software, can realize data bidirectional transparent transmission from Serial to Network. It supports custom registration package, heartbeat package, 4 Socket connection, and USR-Cloud access. With high speed, low latency, support FTP protocol upgrade.
1. Network transparent transmission mode
In this mode, User’s device can send data to specified server by WCDMA network. G761 support 2 socket link, that is Socket A and Socket B, two links is mutual independence.
2. HTTPD Client Mode
In this mode, the data will sent to HTTP server directly, or obtain data from HTTP server. The data will sent to Web server(apache, IIS, tomcat, etc) in Http(GET/POST) mode as long as sending data in formal format. User can utilize the scripting language like PHP, ASP as database storage.
3. SMS transparent transmission mode
In this mode, user’s device can send SMS to specified phone, or transmit the SMS from phone to device. The transparent transmission between device and phone can realised by parameter setting.
4. AT command
When G761W working in any kind of mode(Network transparent transmission, SMS transparent transmission, AT command), user can send specified data, then let WCDMA switch into AT command mode.
Baud Rate Synchronization
4G modem support baud rate synchronization protocol, can change serial baud rate, data bits, check bits, stop bits dynamically. Suitable for USR VCOM software, serial parameters changed in VCOM, serial parameters of G780 been changed automatically.
USR-G780 4G DTU as TCP CLIENT, after establishing TCP connection successfully, it can sending scheduled registration package automatically in order to TCP Server remark this data. Registration package can be IMEI code, ICCID code and custom registration data.
Heartbeat Package Mechanism
4G Modem support network heartbeat package and serial heartbeat package.
Network heartbeat package is used for notify server the activity status by sending heartbeat package continuously.
Serial heartbeat package is used for notify serial device the activity status by capturing data from sensors, can not push.
