Product Overview

Null-modem emulator
Null-modem emulator

Description: A null-modem emulator is a software program that emulates a null-modem cable connection between two serial ports on the same computer. This allows applications that expect a direct serial connection to communicate with each other locally.

Type: software

Pricing: Free

Serial to Ethernet Connector
Serial to Ethernet Connector

Description: A serial to Ethernet connector is a device that converts serial communications from a device like a PLC or instrument into Ethernet, allowing the device to connect to a network. It acts as a bridge between legacy serial devices and modern TCP/IP networks.

Type: software
