Introduction

Xtreme/104 Opto adapters are high performance multi-port serial adapters for PC/104

stacks that enable you to connect up to four serial devices per board. Each port is optically

isolated from each other and from the board up to 3.0 kV AC, RMS.

Features

 Two or four asynchronous serial ports

 RS-232 and/or RS-422/485 electrical interfaces

 Interfaces are jumper selectable for each port

 Each port is individually optically isolated up to 3.0 kV AC peak to peak

 Industrial temperature model operates between -40 and 85 degrees Celsius (-40 to 185 degrees

Fahrenheit)

o Industry Compatible model is -40 to +85 Celsius.

 Multiple Xtreme/104 Opto adapters may reside in a system

 16C2850 dual UARTs control each port. The 16C2850 has 128 byte transmit and receive FIFO

buffers for each port and automatic software/hardware flow control

 Each port has independent baud rate selection offering baud rates from 50 bps – 230.4 Kbps

(RS-232) and 50 bps – 460.8 Kbps (RS-422/485), with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop

bits, odd or even parity

 On-board jumpers allow the selection of 8 predefined I/O address sets

 On-board jumpers allow the selection of 1, 2 or 4 IRQ lines. Choose from interrupts 3, 4, 5, 6,

7, 9, 10, 11, 12, 14 and 15

● Driver support for Windows 9x, Windows CE/CE .NET, Windows XP and Windows NT/2000,

Windows 7, Linux, Solaris, SCO Unix, QNX 4, 6 (Neutrino) and VxWorks

Optical Isolation

The Xtreme/104 Opto uses opto couplers and isolated DC to DC converters to achieve

optical isolation. The board provides 3.0 kV AC RMS isolation between each port and also

between each port and your system. There are some considerations to note.

 Optical isolation can degrade if the board is subjected to high humidity, especially conditions

that are right for condensation to occur.

 Optical isolation can degrade if airborne dust is allowed to accumulate on the surface of the

board.

 An electrical shock hazard could exist depending on what equipment is connected to the

Xtreme/104 Opto. Under these circumstances the wiring and/or cabling leading to the serial

port connections may have high voltages on them. You must use appropriately insulated cables

in these situations.

 Please contact your Connect Tech Technical Support Specialist for any questions related to the

application of optical isolation.
