The ModBus RTU GPRS IOT Gateway is a fully plug and play IOT device which enables any ModBus slave device(s) to be connected to cloud server in minutes. There is no coding needed. It comes with inbuilt ModBus master capability and also other intelligence needed to communicate with any cloud server. It is remotely configurable via our Web configuration portal for user settings such as slave id, register addresses, data type, server url, data transfer rate etc. Even a technician can configure and get the automation running in minutes. If Tangent Cloud IOT platform is selected as the server, the user can visualise the modbus data in Tangent cloud dashboard in form of graphs, widgets, alerts etc.

Modern communication requirements require the use of cellular network with PBX devices and GSM gateways have come as a blessing for the enterprises having GSM non compatible PBX’s. SIMADO GFX44 connects existing telephony devices with the via FXS interface. It is a fixed configuration voice GSM Gateway.

GSM FCT for Mobile SIM (All 4G SIM Supportex except RELIANCE JIO) i.e. VOLTE not supported. Converts your mobile number to wireline phone Allows you to connect telephone handset or can connect to EPABX Compatible with All Korecall phone recorders   GSM FCT (Fixed Cellular Terminal) is a compact fixed cellular terminal used to make and receive calls over GSM network while retaining the existing infrastructure. GSM FCT eliminates interconnection charges and provides substantial cost savings by turning all calls into mobile-to-mobile calls. It easily integrates with any PBX or telephone via GSM network. GSM FCT is ideal for small offices, remote project sites and retail shops for cost-effective and reliable communication.   Features:   Make and receive mobile calls from conventional analog phones Quad-band GSM and Tri-Band network operation Caller ID presentation on analog extension Due to intense competition in the mobile network market, mobile providers offer lower tariff rates compared to landlines for Subscriber Trunk Dialling (STD), International Subscriber Dialling (ISD) and Closed User Group (CUG).

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
