2: Introduction The UDS2100 is a 2-port device server that provides a quick, simple, and costeffective way to bring the advantages of data accessibility and remote management to devices not currently connected to a network. Applications The UDS family of Device Servers allows serial devices, such as those listed below, to connect and communicate over Ethernet networks using the IP protocol family (TCP for connection-oriented stream applications and UDP for datagram applications).
2: Introduction Figure 2-1. Serial Tunneling Example The Com Port Redirector software included on the product CD simplifies the integration process by extending the functionality of COM-port-based Windows™ applications. Virtual COM ports, mapped to remote device servers on the network, can replace direct serial connections. Figure 2-2.
2: Introduction Protocol Support The UDS uses the Internet Protocol (IP) for network communications and the Transmission Control Protocol (TCP) to assure that no data is lost or duplicated and that everything sent to the connection arrives correctly at the target. Supported protocols include: ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network communications. TCP, UDP, and Telnet for connections to the serial port. TFTP for firmware updates.

A: Mounting Brackets The following drawings provide dimensions of the brackets for mounting the UDS2100.
B: Alternative Ways to Assign an IP Address Earlier chapters describe how to assign a static IP address using DeviceInstaller, Web Manager, and Setup Mode (through a Telnet or serial connection). This section covers other methods for assigning an IP address over the network. DHCP The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit boots up.
B: 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. To assign a temporary IP address: 1.
C: Binary to Hexadecimal Conversions Many of the unit’s configuration procedures require assembling a series of options (represented as bits) into a complete command (represented as a byte). Convert the resulting binary value to a hexadecimal representation. Converting Binary to Hexadecimal Following are two simple ways to convert binary numbers to hexadecimals. Conversion Table Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A (for 10), B (for 11), etc.
C: Binary to Hexadecimal Conversions Scientific Calculator Another simple way to convert binary to hexadecimals is to use a scientific calculator, such as the one available on Windows’ operating systems.
