The DVR2000E is an electronic, solid-state, microprocessor-based control device. The DVR2000E regulates the output voltage of a brushless, ac generator by controlling the current into the generator exciter field. Input power to the DVR2000E is from a multi-pole, high-frequency, permanent magnet generator (PMG). The DVR2000E is supplied in an encapsulated package designed for behind-the-panel mounting. The DVR2000E is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate regulator status and system conditions. DVR2000E connections are made through quarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the DVR2000E and an IBM compatible PC
COMMUNICATION PORT A communication port is located on the rear panel and consists of a female RS-232 (DB-9) connector. The communication port serves as an interface for programming (setup) of the DVR2000E. Figure 2-2 illustrates the location of the communication port. Programming requires a standard 9-pin serial communication cable connected between the DVR2000E and an IBM-compatible PC or handheld computer operating with MARATHON-DVR2000E-32 software. MARATHON-DVR2000E-32 is a Windows® 98/NT based communication software package that is supplied with the DVR2000E. A detailed description of MARATHON-DVR2000E-32 software is provided in Section 5, MARATHON-DVR2000E-32 Software.
