ADAM-4561 User Manual 2
Chapter 1 Overview
1.1 Introduction
Advantech’s ADAM-4561 allows PC users to connect their serial devices
to systems that use USB interface. By attaching the ADAM-
4561 to a PC, it will no longer be necessary to open the chassis or turn off
the PC to install the hub. With the ADAM-4561, the user instantly gets one
extra high-speed RS-232/422/485 ports. In addition, since the power is
derived from the USB port, there are not any cumbersome power adapters.
This makes the ADAM-4561 especially suitable for printers, POS system
and industrial control devices.
Compliant with USB v1.1, the ADAM-4561 features a lot of powerful func-
tions such as high-speed 115.2 Kbps, support for various operat- ing sys-
tems, independent RS-232/422/485 port and more. By simply plugging in a
USB hub, the ADAM-4561 eliminates configuration issues associated with
expensive, antiquated card solutions. This eliminates the need to remove
the PC cover and or to reboot the operating system during installation.
The user only installs the driver, and follows the on-screen instructions.
This reduces a lot of program- ming time.
The USB interface, now standard on virtually all new PCs, offers signifi-
cant advantages over earlier bus types. A signal USB interface can con-
nect up to 127 devices at data rates up to 12 Mbps. This kind of easy and
convenient connectivity means that your network can grow with your
needs.
