Network Gateways Dealers in Chennai

In the busy world we have to do more calls in high networks for this it is used as SIMADO GFX44 is a fixed configuration GSM3G-FXS voice gateway. It connects with the existing telephony devices via FXS interface. Up to 4 SIM cards can be placed inside the SIMADO GFX44 gateway allowing up to 4 concurrent calls. The calls to mobile numbers are placed via the GSM3G SIM cards, reducing higher fixed-to-mobile interconnection charges.

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.
