The fourth generation of Com Port Redirector has been completely redesigned. 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.Ĭom Port Redirector (CPR) v4 and TruPort® Technology A device server attached to the network receives the data and transfers it from its own serial port to the attached equipment.Ĭonversely, 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. Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. It redirects application data destined to an attached device via the PC’s local serial (COM) port. Mapping COM Port-based Serial Applications Over EthernetĬom Port Redirector (CPR) is software that maps ‘virtual COM’ ports on a PC platform. That’s where Com Port Redirector comes in. But, the moment the device is placed on an Ethernet network and direct serial connection is broken, the ability of the application software to communicate with the device is lost. Equipment ranging from POS bar code scanners, to medical equipment, to surveillance cameras, to RFID readers typically use COM Port-based application control software.Īs long as the attached device is within the limited distance reach of the PC, this works great. Serial-based communication is used almost everywhere to access and control devices.
