  • Page 14: Xpress Dr-Iap Industrial Device Server

    Note: This section is for the XPress DR-IAP only. The Lantronix Industrial Automation Platform (IAP) family of device servers allows a single network and protocol to connect multiple serial devices from many vendors. IAP provides the automation industry with a network-enabling solution using TCP/IP and standard Ethernet networks that is vendor-independent.

  • Page 15: Protocol Support

    IP Address Every active device connected to the TCP/IP network must have a unique IP address. This IP address is used to reference a specific device, for example, to build a connection to XPress DR’s serial port. See for a complete description of IP E: Alternative Ways to Assign an IP Address Addressing.

  • Page 16: Port Number

    IP address/port number combinations must be different. In the XPress DR, a port number can be configured on the channel (port). The XPress DR uses this port number for outgoing messages and incoming connections, or UDP datagrams, which are addressed to its port number.

    C: Connections and Pinouts Power Requirements The XPress DR device server is normally powered by the same 12 VDC or 24 VDC supply that powers other devices in your panel. Many AC-powered industrial controllers also supply 24 VAC for use by field devices. The XPress DR is not shipped with a separate power supply, but any power supply with a Limited Power Source (LPS) between 9-30 VDC or 9-24 VAC can be used.

  • Page 91: E: Alternative Ways To Assign An Ip Address

    Provided a DHCP server exists on the network, it will assign the unit an IP address, gateway address, and subnet mask when the unit boots up. The XPress DR has acquired an IP address if the red LED stops flashing and the green Status LED is on continuously. (If no DHCP server exists, the unit responds with a diagnostic error: the red Diagnostic LED blinks continuously, and the green Status LED blinks five times.

    B, C. A netmask defines how many bits from the IP address are to be taken as the network section and how many bits are to be taken as the host section. When the number of host bits is entered, the XPress DR calculates the netmask. The netmask is displayed in standard decimal- dot notation.

    E: Alternative Ways to Assign an IP Address BOOTP Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific duration of time. ARP and Telnet If the unit has no IP address, you can use Address Resolution Protocol (ARP) method from UNIX and Windows-based systems to assign a temporary IP address.

  • Page 95: F: Binary To Hex Conversion

    F: Binary to Hex Conversion Many of the device server’s configuration procedures require you to assemble a series of options (represented as bits) into a complete command (represented as a byte). The resulting binary value must be converted to a hexadecimal representation. Converting Binary to Hexadecimal The following are two simple ways to convert binary numbers to hexadecimals.
