DESCRIPTION:
This high density intelligent DSP-based VME card incorporates four separate transformer isolated Digital-to-Synchro
converters with 1.2 VA drive capability, wrap-around self-test, and signal/reference loss detection. Either one
common or four separate reference inputs can be specified. This card offers two-speed configuration and constant
rotation that includes a start and a stop angle. Transformer isolation enables user to ground one of the outputs
without effecting performance. External amplifiers, to handle 30 VA from 50 Hz to 400 Hz, can seamlessly be
integrated. If Geographical Addressing is part of the overall system, this card will respond, otherwise the board DIP
switches will be activated to set base address. A watchdog timer is provided to monitor the processor. This model
will drive passive loads such as CT's etc. A green LED is provided on front panel "F" models only, to visually indicate
proper card performance. Analog outputs can be specified either via P2, front panel or both. Part #, S/N, Date Code,
and Revision are located in permanent memory locations.
Major diagnostics are incorporated
to
offer
substantial improvements to system reliability, because the user is alerted
(within 5 seconds) to channel malfunctions. This approach reduces bus traffic, because the Status Registers do not
require constant polling. See Programming Instructions for further details.
The D2 Test
initiates automatic background BIT testing that compares the output of each channel against the
commanded input to a test accuracy of 0.05
°
and monitors each Output and Reference. A failure triggers an Interrupt
(if enabled) and results are available in Status Registers. The testing is totally transparent to the user, requires no
external programming, has no effect on the standard operation of this card and can be enabled or disabled via the
bus.
The D3 Test
starts
a BIT test
that generates and tests 72 different angles, to a testing accuracy of 0.05
°
. Results can
be read from Status Registers. External reference is required. Testing requires no external programming, and can
be Initiated or terminated via the bus. CAUTION: Outputs are active during this test. Check connected loads for
possible interaction.
Power-On Self-Test
(POST),
if enabled, initiates the D3 Test upon turn-on and is enabled/disabled via the bus.
The "C" version operates from 0°C to +70°C and is populated with standard high quality commercial semiconductors.
The "M" version, used for severe environmental conditions, operates from -55°C to +85°C and is populated with high
quality extended temperature semiconductors. Conduction cooling, using a thermal plane and wedge locks, can be
specified. A stiffener improves vibration response. Both sides of the board can be conformally coated. All “M” boards
are burned in for 24 hours and cycled from -55°C to +85°C.
