2 ADAM-4561 User's Manual
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
functions such as high-speed 115.2 Kbps, support for various operat-
ing systems, 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-
mingtime.
The USB interface, now standard on virtually all new PCs, offers
significant advantages over earlier bus types. A signal USB interface
can connect 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.

2.1 Hardware Installation
2.1.1 Network Architecture
Traditional serial port communication uses a COM port board that
slides into one of the slots at the back of your PC. With the ADAM-
4561, you can access the COM port from USB ports. The ADAM-4561
can be integrated into the network architecture of any protocol.
Note: all the operating systems on your host must
support USB v1.1 standard, such as Windows 98/ME/
2000.USB devicesareused in“Master-Slave”
architecture.Before you use ADAM-4561, you must
determinethe masterPC.
The following illustration shows the network architecture:

2.1.2 Network Connection
When using the ADAM-4561, you will simply plug one end of USB
cable (included in package) into ADAM-4561, and the other end into
the USB hub or your host PC.
2.1.3 Serial Connection
The model of the ADAM-4561 that you purchased has 10 pin connec-
tor for connecting serial ports on the bottom of module. Only one set
of twisted-pair cables is required to transmit both Data and RTS
signalsfor RS-485interface.
Note: In USB v1.1 standard, If you have used the COM3, COM4…..
COMn of host PC. When you plug ADAM-4561 in the host PC, the
COMport willbe COMn+1.

2.1.4 Jumper Settings
Jumper JP1 sets the driver enable mode selection. If jumpers JP1 is set
at “AUTO,” the driver automatically senses the direction of the data
flow and switches the direction of transmission. Handshaking is
unnecessary. If jumper JP1 is set to “On,” the driver is always enabled,
and always in high or low status. The user must select a mode before
beginning RS-422 applications.
