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
www.DataSheest4uUpp.coormts 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
(SRTbus™) 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.

* 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)
*** Contact VMIC for availability of transformer-coupled outputs and higher voltages.
Notes
1. All synchro/resolver boards require external ±15 V power supplies. Power and
reference inputs can be connected to P2 or P3 (front panel). Power input connectors
are available on VMIC's synchro/resolver backplane (SRTbus).
2. The reference input voltage can be jumper-selectable (by the user) for 1.3, 26, or
115 VRMS. Contact VMIC for other reference input voltages.
3. To 10 kHz with reduced accuracy.
