Line driver cards plug into line driver card racks and provide a variety of data protocols: Polling Radio, RS-422/485, audio, fiber optics, RS-232, Ethernet and high level line drivers.
Line drivers provide line-to-line isolation so that all DGMs are not on the same line. This is important when the multiplexing system is used for campus wide monitoring.
Any combination of up to 32 line drivers may be installed in one line driver rack. Four line driver card racks can be installed on a single System 3505 for a total of 128 line driver cards. Other options that utilize line driver cards and the line driver rack include: the Network option, Q-MUX™ options, and the Remote Line Printer option.
