Overview Industio—The Industrial Multiport Async Solution Moxa Industio products are smart, multiport serial I/ O solutions for industrial applications. The Industio CP-134U Series boards , includi ng CP134-UI and CP-134UL , are de signed for a 32-bit PCI bus with the Plug and Play and Universal PCI feature.
Introduction PCI BIOS. This means that th e board MUST be pl ugged into the com puter first before installing the driver so ftware. For more PCI information, refer to the Technical Reference Appendi x. Universal PCI The 32/64-bit PCI local bus sp ecification specifies both 3.
Features The Industio CP-134U Series includes the following products: CP-134U 4 RS-422/485 po rts, Universal PCI inte rface with embedded Surge Protecti on and Isolation P rotection (16 KV ESD, 2 KV I.
2 2 2 Hardware Installation You will need to install both hardware and so ftware for Industio CP-134U Series boards. The hardware install ation procedure is given in this chapter, and the next chapter deals wi th software installation for vario us operating system s.
CP-134U Series Block Diagrams Industio CP-134U Series boa rds’ hardware config uration for IRQ num ber and I/O address is automat ically assigned by t he PCI BIOS. This m eans that the boa rd MUST be plugge d in first before installing the driver software.
Hardware Installation CP-134U The Industio CP-134U Seri es has two 30-pin jumpers and t wo sets of four DIP Switches on the board that allow the us er to set the seri al interface for each of t h e board’s four ports. Ports 1 and 2 c an be set to RS -232, RS-422, RS-485 (2-wir e), or RS-485 (4- wire).
Jumper Settings The two on-board 30-p in jumpers are us ed to select between the RS-23 2 and RS-422/485 serial interfaces. If you select RS-422/485, th en you will also need to set the DIP Switches to select between RS-422 , RS-485 (4-wire), an d RS-485 (2-wire).
