Proper Operation Mode Real COM Mode NPort W2004 comes equipped with COM drivers that work with Windows 95 98 ME NT 2000 XP systems The driver establishes a transparent connection between host and serial device by mapping the IP Port of the NPort W2004 s serial port to a local COM port on the host computer One of the main conveniences of using Real COM Mode is that Real COM Upon directly with data transmission connection Mode allows users to continue using request not required RS 232 422 485 serial communications software that was written for pure serial communications applications The driver intercepts data sent to the host s COM port packs it into a TCP IP packet and then redirects it through the host s Ethernet card At the other end of the connection the NPort W2004 accepts the Ethernet frame unpacks the TCP IP packet and then transparently sends it to the appropriate serial device attached to one of the NPort W2004 s serial ports ATTENTION Real COM Mode allows several hosts to have access control of the same NPort W2004 The driver that comes with your NPort W2004 controls host access to attached serial devices by checking the host s IP address Refer to Accessible IP Settings in Chapter 5 for more details NPort W2004 I 4 4 5 Web Console Configuration The Web Console is the most user friendly method available to configure NPort W2004 Series This chapter introduces the Web Con
