It acts as a communication link between the store’s host computer and one or more Portable TeleTransaction Computers (PTCs). The Connection Manager can send data to and receive data from the host and the PTCs. The Connection Manager is wired to the host computer via an RS-232 serial cable or can be connected to an Ethernet network to which the host is connected. The Connection Manager establishes wireless communication links with PTCs used throughout the store. The PTCs, which can consist of any combination of up to eight PTC-921 DOS and/or PTC-960LE units, and the Connection Manager communicate with each other via their internal MiniNet 2.4 radio modules. Light-emitting diodes (LEDs) on the Connection Manager’s front panel indicate the status of power input, error conditions, and communication connections. Processor The Connection Manager’s 66-MHz AMD Elan SC400 processor is fully IBM PC compatible. It provides exceptional processing speed and is designed for low power consumption. Operating system The Connection Manager uses the MS-DOS 6.22 operating system (ROM version). 11 Memory The Connection Manager has two types of memory: read-only memory (ROM) and random access memory (RAM). ROM The Connection Manager comes with 256 kilobytes (KB) of flash BIOS programmable read-only memory. It is used to store the operating system, BIOS, and flashing kernel. RAM The Connection Manager has 4 MB of random access memory. RAM is used to store data the Connection Manager needs while it is running. One MB of RAM is reserved for running the operating system and your application. Data stored in RAM can be easily read, written, and changed. It is also volatile. All data in RAM will be lost if power to the Connection Manager is terminated. Radio The Connection Manager contains a MiniNet 2.4 low-power frequency-hopping radio module. This radio allows the Connection Manager to interactively communicate in real-time with PTCs on a radio-based local area network. It provides secure, interferencefree communication and does not require a license for operation. 12 Entering data Data can be entered into the Connection Manager via its MiniNet 2.4 low-power frequency-hopping radio module or through its RS-232 COM1 and COM2 serial ports or Ethernet port. Storing data Data entered into the Connection Manager can be stored in the PTC’s RAM, on the internal 4-MB IDE-compatible solid-state hard drive, or on 3.5-inch, 1.44-MB, high-density floppy diskettes (if your Connection Manager was ordered with the optional floppy drive). 13 Getting started Unpacking the Connection Manager Any additional accessories are shipped separately.
