FUNCTIONAL DESCRIPTION

The USB-COM-2SM is a two-port asynchronous serial communication adapter designed for use with any computer system equipped with a USB port.

Multiple peripherals such as POS, barcode scanners, scales, date-entry terminals, data acquisition modules, and automation equipment can now be

recognized and used on a single USB port. Simply install the included software and connect the unit to your USB port. It instantly provides two RS-

232, RS-422, or RS-485 serial ports which can be selected on a port by port basis. It is now easier than ever to add serial ports and serial devices to

any application along with easy plug-and-play and hot-swapping features. The unit enclosure is 4 inches wide by 4 inches deep by 1.8 inches high.

The adapter is supplied with a 6 foot USB cable and has two male DB9 connectors with jack-screws for secure cable connections. The DB9 connec-

tors are conveniently located at the front of the unit and feature easy-to-read LEDs indicating serial port activity. The USB connector is located at the

back of the unit and also features a LED for USB status. The USB-COM-2SM is fully compatible with both USB 1.1 and USB 2.0 ports. The OEM

(board only) version provides just the board without the enclosure and is ideal for a variety of embedded OEM applications. An additional USB input

header is provided on the board for OEMs along with a downstream USB port for connecting additional USB devices.

SERIAL

Type FT232 UARTs are used as asynchronous communication elements. This includes 384-byte receive / 128-byte transmit FIFO buffers for high

data throughput and to protect against lost data in multitasking systems. Crystal oscillators located on the card permit precise baud rate capability up

to 230.4K for use in RS-232 mode, using ICL3243 type drivers. Speeds up to 921.6K are achievable using RS-422 & RS-485. The driver/receivers

used are type SP491 which are capable of driving long communication lines at high baud rates. They can drive up to ±60 mA on balanced lines and

receive inputs as low as 200 mV differential signal superimposed on common mode noise of +12V to -7V. In case of communication conflict, the

driver/receivers feature thermal shutdown.

OEM USB/104 FORM FACTOR

What makes the OEM option unique is that its PCB size and mounting holes match the PC/104 form factor (without the bus connections). This allows

our rugged digital/serial board to be added to any PCI-104 or PC/104 stack by connecting it to a simple USB port usually included on-board with

embedded CPU form factors such as EBX, EPIC, and PC/104 - especially important since many newer CPU chipsets do not support ISA and have

plenty of USB ports. Future stacks will be using the extremely fast PCI Express bus which is essentially overkill for simple digital monitoring and con-

trol. The USB-COM-2SM OEM board can also be added into many pre-existing standard PC/104 based systems and enclosures.

ACCESSORIES

The USB-COM-2SM is available with optional DIN rail mounting provision.

SOFTWARE

The USB-COM-2SM is plug-and-play which allows quick connect or disconnect whenever you need additional serial ports through your USB port. The

USB-COM-2SM is supported for use in most USB supported operating systems and includes a free Linux and Windows 98se/Me/2000/XP/2003

compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for

Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard DLL interface usable from the

most popular application programs. Embedded OS support include Windows Xpe. For serial communications the package includes an easy to use

terminal program for testing out your COM ports. Use in other operating systems may also be supported, contact Factory.
