Analog multiplexer with 8 switchable channels
Switch RS-232C, RS-422/485 signals by USB, external input or manual switch
Overview
USB-404 is a multiplexer that can switch one common port to one of eight 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 eight units in a single setting during automatic equipment inspection.
Features
- 8 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. - Uses high-retention industrial grade USB connector
- USB line has ESD protection
- Includes a USB A-B cable (1.8m)
- Includes an AC adapter
- Non-use of 10 Restricted substances of RoHS directive
- MADE IN JAPAN
Pinouts and Wiring between COMMON port and each channels
