What makes Edgar unique?
- Power output - Edgar can power an external device using its VOUT terminal. The Voltage Output can be 5, 9, 12 or 24 V. It is possible to switch it on or off via a web browser. (Power supply voltage must be greater then required Vout voltage)
- HTTP GET communication allowing an easy access to the serial port from a WEB server.
For the communication, TCP server, TCP client or UDP can be used.
A pair of Edgar's can be set up in Client-Server mode where they will send serial data between each other without any PC intervention.
Edgar can send packets from / to the serial line via HTTP GET. From a web server, the data packet can be sent as an HTTP GET request. Similarly, if the data on a serial line - for example, from a connected barcode reader - comes in, the converter can send the data to the web server as an HTTP GET request.
How does HTTP GET work in an Ethernet converter to a serial port?
This feature allows data from the serial port to be sent as HTTP GET requests to a remote server. In the reverse direction, the data from the remote server can be sent to the serial line directly by replying to the GET request sent by the converter.
The connection can also be initiated from remote server side. The server sends HTTP GET to the set.xml script in the converter. Data can be sent as an ASCII character string or using hexadecimal form as binary data. GET communication can be optionally secured with 128bit AES encryption.
Power Output VOUT
Power output VOUT is mostly used in situations where the converter is powered from PoE. VOUT power output can power the connected device as well. Therefore no additional power supply is needed for the device connected to it.
Power output is DC and the voltage is determined by the switches on the side of the converter. Power output can be switched on or off using the web interface. The output voltages can be selected using a DIP switch on the side of the device. You can chose from the following options:
- 5 V / max. 630 mA
- 9 V / max. 350 mA
- 12 V / max. 260 mA
- 24 V / max. 130 mA
Com Port Redirector
Com Port Redirector (CPR) is software that maps ‘virtual COM’ ports on a PC platform. It redirects application data destined to an attached device via the PC’s local serial (COM) port. Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. A device server attached to the network receives the data and transfers it from its own serial port to the attached equipment.
Conversely, data sent from the networked equipment to the serial port of the device server is transmitted back to the application software on the PC via Ethernet. Com Port Redirector receives the data and presents it to the control application as if it came from a COM port via a local serial connection.
