[USB-208] USB Multiplexer 4:1 - USB Switching Device HuMANDATA LTD.

Overview

USB-208 is a multiplexer that can switch one common port to one of four channels. 
RS-232C, RS-422/485, and other analog signals can be switched by the following three ways.

• Sending simple commands from a PC via USB
• External input, no-voltage contact input or DC input can be selected
• Switching manual switch on the main body

It supports analog signal voltage range of ±25V and data rate up to 20Mbps.
The system can also be used to save labor in the inspection process. 
It allows four units in a single setting during automatic equipment inspection.
