Xtend Fixed Cellular Terminal (FCT) is a telecommunication equipment that can be used to connect a Telephone or EPABX to the GSMCDMA Mobile Network. Xtend FCT provides instant phone connections similar to landlines; even in remote areas, construction sites, project offices, offshore oilrigs, and ferries. They can also be used to provide emergency backup phone lines when conventional phones fail during road repairs, floods, etc. Xtend FCT is a boon to call centres and other organisations with a large number of outgoing calls. Organisations with one or more branches can benefit from the facility of making interoffice calls and calls to field staff using Xtend FCT.

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
