COMNet

System for remotization of serial local communication in standard RS-232, RS-485 or CAN-bus.

COMNet system allows users to connect remotely with devices equipped with RS-232, RS-485, CAN-bus, replacing traditional serial communication which is commonly performed locally (i.e. between peripherals and custom boards or between a PC-based proprietary application and a lift controller board).

Setting up a COMNet system requires installing the COMNet PC Client software in the PC which will be used for remote-monitoring and connecting a GSM500.net / 3G.next / 4G.next / 4G.Router gateway to the serial port of the remote device to be controlled.

The COMNet system allows to set up a remote two-way data communication. The data flow coming out of the remote device will be sent to the same application commonly used for local wired communication or to the a physical COM port of the computer.  

The connection procedure simply requires to enter the SIM card telephone number associated with the remote GSM500.net into the COMNet PC Client. This eliminates any difficulties in locating remote devices not assigned to static IP addresses.

The data connection is established by the system on demand and the data are transferred via GPRS over an esse-ti proprietary server (COMNet Server).  

The GSM500.net / 3G.next / 4G.next / 4G.Router connected to the remote device to be monitored, may also be used as a standard GSM gateway for voice transmission, by means of the dedicated plug or connector (i.e. it can be connected with the elevator emergency phone dialer) and the same SIM card needed for remote monitoring. Due to the characteristics of the GPRS network, the voice call is always privileged over the data transmission, therefore in case of a voice emergency call, the ongoing data connection will be automatically cut off.
