Network Gateways Dealers

We are offering ethernet modbus gateway. The ethernet modbus gateway allows serial modbus rtus to communicate and interoperate with modbus/tcp based controllers. The modbus standard protocol is an asynchronous protocol designed to connect directly to computer asynchronous ports. Modbus has been extended to operate over ethernet using the ip protocol suite. This gateway converts between the modbus tcp/ip protocol and modbus ascii/rtu protocols transparently. the emg-01 can operate in four different modes viz, modbus rtu slave, modbus rtu master, modbus ascii slave or modbus ascii master. Depending up on the mode the modbus tcpip connection is emulated. the emg-01 is powered by powerfull 32bit controller and can support multiple socket connections. Emg-01 has built in web server which servers web pages to monitor the status of the device and also to set the various device configurations. multi mode operation configuration via browser protocol aware: minimum configuration needed two serial ports that each support rs-232, rs-485 2 or 4 wire 10 or 100 mbps ethernet rs-232 interface speeds to 230 kbps

Model SC10MK is a programmable, Web enabled Modbus RTU to Modbus TCP protocol converter. High end CPU along with Linux OS makes it an idle choice for applications like Meter readings, Solar controls & any other protocol conversion applications. 

We make available, the GSM Gateway System, which has 8 SIM Card slots and is very lightweight (1-1.2kg). The wide range of products is a result of intense quality analysis of raw materials at the initial stages of production. With stern checking, the products are examined with utmost precision. We are working with a group of quality examiners who conduct several tests on the offered lot for confirming its compliance with the quality standards.

A GSM Gateway or Fixed Cellular Terminal is a device which reduces costs when calling from a fixed telephone line to GSM network. In general, calling from the fixed network to a mobile network is more expensive than calling between mobile networks.

GW1102-2D(RS-485) is an industrial Ethernet Modbus gateway that converts between Modbus TCP and Modbus RTU/ASCII protocols. It provides 2 port RS-485/422 serial (5 bit terminal block) and 1 port 10/100M Ethernet.Modbus TCP, Modbus RTU and Modbus ASCII protocol are integrated in the products, users can easily realize the seamless integration of Modbus Ethernet devices and Modbus serial devices and even multi master and slave hybrid networks. At the same time, the user can be set up by Web or Telnet. The simple design can not only realize the fast application, but also guarantee the application of the entire real industrial environment.The products using EMC protection design, can work in rugged environment.   1.Support Modbus TCP, Modbus RTU, Modbus ASCII, IP, ARP, DHCP and DNS protocol2.Support 1 port 10/100M Ethernet3.Support 2 Port RS-485/4224.Support WEB and Telnet configuration5.Convert between Modbus TCP and Modbus RTU/ASCII6.Support RTU Slave, RTU Master, ASCII Slave, ASCII Master four operating modes7.Support ID mapping function, to achieve the management of the host ID8.300bps~115200bps baud rate and nonblocking communication9.Support IP address and MAC address filtering function10.Slave mode support 16 TCP master connections11.Master mode support 32 slave TCP connection requests12.Support Response Timeout and Interval Timeout setting13.Support cross-gateway and cross-router communication14.IP30 protection grade, metal shell, wall mounted installation15.No fan, low consumption design16.Working temperature: -40～75℃   Ethernet portStandard: 10Base-T, 100Base-TXProtocol: Support Modbus TCP, Modbus RTU, Modbus ASCII, IP, APR, ICMP, DNS and DHCPSignal: Rx+, Rx-, Tx+, Tx-Speed: 10/100MbpsWorking: Full-duplex and half duplexTransfer distance: 100mConnector: RJ45Serial portSerial port number: 2 ports RS-485/422RS-485 signal: D+ (A), D- (B)RS-422 signal: T+, T-, R+, R-Parity bit: None, Even, Odd, Space, MarkData bit; 7bit, 8bitStop bit: 1bit, 2bitBaud rate: 300bps～115200bpsRS-485/422 transfer distance: 1200mRS-485/422 connector: 5 bits terminal blockProtection: class 3 staticMaster mode: 32 TCP slaves Slave mode: 16 TCP mastersWork mode: RTU Slave, RTU Master, ASCII Slave, and ASCII MasterLED IndicatorPower (PWR)Ethernet port connect status (Link)Serial port data indicator: TX1~TX2, RX1~RX2;Power requirementsInput voltage: 9~48VDCNo-load consumption: 0.90W@9VDCFull-load consumption: 1.25W@9VDCEnvironment limitsWorking temperature: -40~75℃Storage temperature: -40~85℃Relative humidity: 5%~95%（non-condensing）MechanicalShell: IP30 protection, metal shellInstallation: Wall mountingWeight: 250gSize (L×W×H): 100mm×69mm×22mmStandardEMI: EN 55022 Class A, FCC Part 15 Subpart B Class AEMS: EN 61000-4-2 (ESD), Level 3Shock: IEC 60068-2-27Free fall: IEC 60068-2-32Vibration: IEC 60068-2-6 WarrantyWarranty time: 3 yearsCertificatesCE, FCC, RoHS, UL508 (pending)Packing List1.
