The boards include a convenient Auto-RTS feature, which makes half-duplex RS-485 communications effortless. The 104-COM-8SM and 4SM are feature-rich and allow for the connection of multiple serial devices-ideal for a variety of applications such as POS, gaming systems, machine monitoring and control, military, high-density networking applications or any other application requiring the connection of RS-232/422/485 serial devices to a PC/104 compatible system.

The 104-COM-8SM and-4SM were designed using type 16780 UARTS and include 64-byte transmit/receive FIFO buffers to protect against lost data in multi-tasking systems while maintaining 100% compatibility with all operating system COM port drivers. A crystal oscillator located on the board permits baud rate capability up to 921.6K. ACCES offers the 104-COM-8SM and 4SM in both standard and extended temperature versions ideal for outdoor applications or harsh industrial surroundings.

Other features of the Model 104-COM-8SM and -4SM include:

Operating temperature range: 0 to +70°C (Optional extended temp -40° to +80°C)

Humidity: 5% to 95% RH, non-condensing

Low power required: +5VDC at 80mA typical, (0.4W) No +/-12V required

Field selectable RS-232, RS-422 and RS-485

Programmable individual non-volatile COM base addresses with shared IRQs allow for flexible and easy universal system integration.

Fixed bias and jumper-selectable termination provided on each transmit-and-receive channel

The 104-COM-8SM and -4SM are supported by all operating systems and include a free DOS, Linux and Windows 95/98/Me/NT/2000/XP compatible software package. This includes sample programs and source code in "C" and Pascal for DOS, and "C," Delphi, C++ Builder, and Visual C++ for Windows.
