VMIVME-4905 High Power Digital-to-Synchro/Resolver Converter Board * 14-bit converter with an accuracy as high as 1 arc minute (4 arc minutes is standard) * 3- or 4-wire output for driving synchros or resolvers * Internal transformers (400 Hz options) * Front panel fail LED * Amp D-type (no. 206584-1) * 5 VA, 2 VA (transformer output), or 0.024 VA options * Nonprivileged or supervisory short I/O * Supports off-line and on-line fault detection and isolation * Compatible with Intelligent I/O Controllers DESCRIPTION -- The VMIVME-4905, a digital-to-synchro or resolver converter (DSC/DRC) board, utilizes the NATEL-HSDR 2514 converter module. It supports a wide variety of options which are supported by configuring jumpers on the basic printed circuit board and by installing optional parts (see the Ordering Options). The VMIVME-4905 board, with supported Built-in-Test VMIC hardware, features both offline and online fault detection and isolation. The Built-in-Test features require a VMIC quad-channel synchro-to-digital converter (SDC) board (VMIVME-4911) or a single channel SDC board (VMIVME-4910) and a standard synchro test backplane (SRTbusTM) installed in the P2 position of a standard VME chassis (refer to VMIC's Synchro/Resolver (Built-in-Test) Subsystem Configuration Guide, Document No. 825-000000-004). The board accepts a 14-bit digital output word (shaft angle), a reference excitation voltage, and produces a synchro or resolver output. The board is ideally suited for computer-based systems in which digital information is processed, such as simulators, robotics, and other control-oriented systems. The DSC/DRC is provided with several options and is capable of interfacing with most standard synchro or resolver devices. FUNCTIONAL CHARACTERISTICS Compatibility: VMEbus specification compatible. Double height form factor. Output Connector Type: AMP no. 206584-1 Output Organization: Two ports, 16 bits wide. Addressable to any address within short supervisory or short nonprivileged I/O map. Address Modifier Codes: Jumper selectable for short supervisory or short nonprivileged I/O access. Factory configured for short supervisory I/O access. Addressing Scheme: Two ports individually addressable on 8- or 16-bit boundaries. Two eight-position DIP switches provide unlimited short data I/O address map selection.

The IIOC firmware is not compatible with the VMIVME-4910. Built-in-Test DESCRIPTION -- The VMIVME-4905 supports fault detection and isolation when used with the VMIC SRTbus and the model VMIVME-4911. The SRTbus is a synchro/resolver test bus that utilizes the user I/O pins on the P2 VMEbus connector. Programming the proper control bits in each output word of the VMIVME-4905 allows field disconnect and/or real-time loopback testing via the SRTbus and the VMIVME-4911. The user should refer to the VMIVME-4905 functional block diagram and the synchro/resolver (Built-in-Test) Subsystem Configuration Guide for a thorough understanding of the Built-in-Test operation. Notice -- The VMIVME-4905 is an enhanced version of the VMIVME-4900 series with different programming requirements. The VMIVME-4905 is not software compatible with the VMIVME-4900 series. Caution -- When driving instruments with one or more phase connections grounded, transformer isolation is required. Built-in-Test requires one synchro/resolver-to-digital converter board for wrap-back testing of the digital-to-synchro/resolver converter board. Refer to the VMIC Synchro/Resolver (Built-in-Test) Subsystem Configuration Guide (Document No. 825-000000-004) for a detailed discussion. ** Reference to accuracy 4 = 4 arc minutes (standard stock item) 2 = 2 arc minutes (long lead time is typical) 1.5 = 1.5 arc minutes (long lead time is typical) 1 = 1 arc minute (long lead time is typical) *** Line-to-Line voltage for synchro outputs.
