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
(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.

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.
Connector Data
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.

Notice — If this board is used with VMIC’s Intelligent
I/O Controller (IIOC) product line (VMIVME-9015,
-9016A, -9017, -9027, -9065, -9066, -9067, and -9068), a
quad-channel S/D board (VMIVME-4911) and SRTbus is
required for Built-in-Test. 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.
4. External ±15 V power supply required.
