OSMAC Base User Manual 2 Local Operation 2.1 Overview The OSMAC Base is a desk top system that provides paging and wireless two-way communications. With an Intel 32 bit processor at its core, and 4 megabytes of FLASH memory, the OSMAC Base can handle the wireless communications needs of the small office or a large plant. OSMAC Base features: Ö Stand-alone operation with built-in keypad and LCD display. Ö Two built-in RS-232 serial ports for advanced paging applications.
OSMAC Base User Manual To facilitate sending pages to a large number of different pagers, groups of pagers may be set up in the OSMAC Base. A group is first assigned a number, and the members of the group are programmed into the group pager database. Once a group is set up, a page may be sent to all the members of the group simply by sending the page to the given group. 2.2 Keypad The built-in keypad is used to program the unit, and to manually enter pages.
OSMAC Base User Manual IMPORTANT NOTE: Some keyboards are extremely sensitive to the high RF fields present when an antenna is connected directly to the rear of the OSMAC Base . The keyboard may stop functioning properly after the OSMAC Base transmitter is turned on. If this situation occurs, it is recommended that the antenna be mounted at least several feet from the OSMAC Base or that a different brand of keyboard be used. 2.4 Display There is a two-line, twenty-character LCD display on the OSMAC Base.
OSMAC Base User Manual Typically it takes a second or more to send a page to a pager. If the page is intended for a group of pagers, it may take longer. A group consisting of 10 pagers may take 5-10 seconds to transmit, and a group of 100 pagers may take 50-100 seconds to transmit. 2.6 Group Page The OSMAC Base can send a page to a group of pager numbers through the entry of a single group number.
OSMAC Base User Manual 3 Two-way Radio and Telephone Operation The OSMAC Base has a built-in radio transceiver enabling it to communicate with other two-way radios and to receive over-the-air commands to generate pages, connect to the telephone system, dial phone numbers and answer incoming telephone calls.
