Title: Streamlining Access Control Connectivity: Strategies for network-enabling serial-based peripheral devices for access control applications

Abstract: This paper provides strategies for using device networking technology to expand serial connectivity options in access control systems. It begins by discussing the technologies involved, then provides several examples of how this technology can be used in the field. The paper ends with a list of key features to consider when purchasing device networking products for access control systems.

Title: Expanding Kiosk Connectivity: Strategies for incorporating multiple serial-based peripheral devices into self-ticketing and other point-of-sale kiosk applications

Abstract: This technical paper provides strategies for expanding serial connectivity options in POS kiosks. It begins by discussing the technologies involved, then provides several real-life application examples of how this technology is currently being used in the field. The paper ends with a list of key features to consider when purchasing serial connectivity expansion products for POS kiosk systems.

Title: Cutting the Cord: Advantages of Network-Enabling Serial Devices

Abstract: This technical paper explains how wired and wireless serial device servers can “cut the cord” between device and computer, thereby allowing serial devices to be remotely accessed via any computer. This provides tremendous savings by both eliminating the need for on-site data collection, and enabling remote monitoring and servicing of equipment. The paper covers advanced Ethernet device server networking modes including wireless 802.11b connectivity, IP broadcasting/multicasting and Client modes, and serial tunneling. Detailed application examples are provided.

Title: Goodbye RS-232? Not So Fast!: Serial Port Expansion Can Preserve Existing RS-232 Peripherals

Abstract: This technical paper shows that RS-232 communication is alive and well and at the heart of many I/O intense applications in a broad variety of industries from banking to manufacturing to industrial monitoring and control. Due to the tremendous expense involved in replacing this equipment, it is not likely, or cost effective, to change any time soon. While it is true that RS-232 serial ports are no longer standard equipment on most off-the-shelf computers, it is also true that serial port expansion is available for every system type from PDAs to laptops to desktops to servers. In fact, connectivity innovators continue to work to enhance RS-232 communication adapters to provide RS-232 ports that are faster and more flexible than ever before. This paper provides detailed application examples and explanations of new enhanced RS-232 serial port technologies.

Title: Choices in Serial Connectivity: Technologies for Retail, Banking, Industrial, and other Networking Applications

Abstract: This technical paper explains the busses (PCI, cPCI, PCMCIA, USB, ISA) and platforms (RS-232, RS-422, RS-485) used for serial communication. It provides detailed application examples for a wide variety of implementations such as POs systems, KIOSKs, ATMs, and automated manufacturing systems. In addition to an in-depth discussion of the pros and cons of each interface and protocol, the paper provides a step-by-step worksheet that helps you to choose the technology that is the appropriate choice for a given application.
