Terminals running an operating system on them, and Simple Host Controlled RF Terminals. RF Readers. that Emulate Terminals These readers started. IBM 3. 27. 0 or 5. To emulate an IBM mainframe terminal. There were also units made that emulated PC workstations. Symbol Technologies and Intermec on Local. Area Networks. RF Terminals. Running an Operating System. Many modern RF readers are essentially small handheld personal computers running complex operating system like Windows CE, Windows Mobile, Linux, or any other application driven operating system. They require lots of memory. They are relatively. LAN or WAN, require larger batteries, have short battery life, and are large in size weight to accommodate the extra electronics needed to run the complex operating system and the individual programs. Some even work as web based terminals using web browser based applications for data gathering operations. These terminals almost always require. C program to be written on the terminals, host programs. IT personnel are also required for each. Host Controlled RF Terminals A host controlled RF Terminal is a simpler reader to install and develop applications for, plus it is generally a less expensive piece of electronics since you dont need a powerful operating system with lots of memory to run applications on the individual portable readers instead you have a much smaller unit with long battery life all using simple host generated commands for real time input that is controlled and directed exclusively by the host computer. All of the power of the host computer is controlling each RF Terminal dynamically. These readers require programming on the host computer only and any application that can read. USB port or TCPIP address can control the operation of a host controlled RF Terminal. Such programming is relatively trivial. Existing. application packages can be more easily modified to use these simple RF. The. amount of programming effort is considerably less than with a terminal emulation reader, or even a Windows Mobile or CE based device. Windows mobile based devices require both host programming and programming on the terminals. Plus, with the Worth Data 7. RF Terminals there are no expensive site surveys, or complex IT integration issues with existing LANs or WANs typically a user will just plug in the B5. Base Station access point, running their software on the host computer, and they are up and running in a matter of minutes. RF Terminals that are host controlled and communicate. Terminal Emulators, Windows Mobile, and Windows CE based devices. PC could easily drive a host controlled terminal system, using a RS 2. COM port, at maximum speed. They are far simpler thus less costly, BUT. Even though you can run them in One Way mode. Event Driven Applications. Spread Spectrum. Terminals vs. Narrow Band Terminals. Narrow band refers to. Spread spectrum most commonly.
