Frequently Asked Questions
Before You Buy
Virtual COM port
One of the most common applications of a network serial device is to use it to make a standard serial device accessible on a network. To do this, you need to connect a standard serial device to the DB-9 port on the network serial device. Next you need to connect the network serial device to a TCP/IP network using an Ethernet connection, and then install software on a client machine in order to access the network serial device. The software on the client machine communicates with the network serial device and creates (maps) a virtual COM port on your computer system. The virtual COM port is identical to a physical COM port and can be used in the same way.
Serial IP extender
You can use two network serial devices to extend a serial connection over a TCP/IP network. To do this, you need to configure one serial device as a client and the other as a server. The client and server are configured to transmit and receive data to their respective IP addresses and TCP ports. The serial settings must match for all connected serial devices, including the UART on both units. Depending on the serial device that you are using, you can use the provided software or the web interface to set the configurations.
UDP to serial adapter
You can use a network serial device to translate UDP data to a standard serial connection. The serial device is configured to listen for UDP traffic from specific IP addresses and ports, and will asynchronously transmit the data out of the serial port on the device. To do this, you need to configure UART on the network serial device to match the specifications of the serial receiver.
