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

[USB-208] USB Analog Multiplexer 4:1 Under development

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 side panel

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.

*Second and subsequent images are CG models

* Image with optional accessories

Features

• 4 channel analog signals, RS-232C, RS-422/485 and others, can be switched automatically
• Supports analog signal up to ±25V
• Supports max. 20Mbps
• Switch by sending simple commands from a PC via USB
  You can use our free Application or general purpose terminal software such as TeraTerm.
• Switch by External input
  no-voltage dry contact input or 5 to 24V DC input
• Manual switching by using the switch on the main body of the unit
• Controllable from embedded Linux devices
  It operates as a device of the standard CDC-ACM class.
  For Linux distributions with embedded CDC-ACM device drivers, you can use them without installing the drivers.
  We do not support the use of Linux itself.
