1. QTI/CRI MODULE

Description:

The QTI/CRI module performs the function of the CAIS Bus remote Data Acquisition Unit (DAU) base module. The unit interfaces to the CAIS bus, to an RS232 interface for local programming and to a Module Bus so the user can attach modules for specific data acquisition purposes. The QTI/CRI module contains the power supply for any attached modules. The CAIS DAU_ID is strap programmable at the J1 connector. This base module also provides 24 Bilevel discrete channels as inputs for data acquisition. The unit contains an EEPROM for non-volatile program storage. The unit can be programmed from the CAIS bus remotely or from the RS232 port with a Personal Computer. Windows 95, 98 and, NT software is available.

The QTI/CRI module EEPROM is used to store;

1. Information as to what the attached modules are (Configuration ID's) and how many,
2. Programming values for attached programmable modules (module channel gains, filter cutoffs, etc.),
3. Gains and offsets that can change for each CAIS normal mode address or page command (see QTI/CAD module).

1. QTI/CAD MODULE

Description:

The QTI/CAD module performs 12 bit A/D conversion of the DAU's multiplexed analog bus. The QTI/CAD module provides 2 programmable gain amplifiers and one programmable offset generator. The 2 programmable gain amplifiers and one programmable offset generator are updated on a per sample basis (the module is rated at full CAIS bus speeds). The offset is inserted after both programmable amplifiers, which are in series. The figure below illustrates:

QTI/CAD MODULE

MODULE		PGA1	PGA2	OFG
GAINS:		GAINS:	GAINS:	OFFSETS:
1, 4, 40, 400		1, 0.5, 0.25,	1,	-5.0V,
		0.7247259,	1.25,	-2.5V,
		0.4301597,	1.5,	-1.25V,
MODULE		0.4117136,	1.75,	0V,
OFFSETS:		0.3129751	2,	+0.625V,
See module			2.25,	+1.25V,
Description			2.5,	+2.5V,
			5,	+5.0V

 

The overall channel gain is (MODULE GAIN)*(PGA1 GAIN)*(PGA2 GAIN). The maximum gain is 2000 and the minimum gain is 0.25. There are 224 possible gains, however some are redundant. There are preferred gain setups. For example, a gain of 1 can be achieved by (MODULE GAIN=1)*(PGA1 GAIN=0.5)*(PGA2 GAIN=2) or (MODULE GAIN=1)*(PGA1 GAIN=1)*(PGA2 GAIN=1). The software defaults to the preferred gain setup. Offset and gain possibilities allow for signal levels of up to +- 10 volts.

CONFIGURATION ID:

C000 hex

2. QTI/CDI32 MODULE

Description:

The QTI/CDI32 module performs the multiplexing of 32 high level differential analog inputs and provides overvoltage protection of +- 30 volts on each input. Signals of up to +- 10 volts can be input to this module. The module can be ordered with 2 standard fixed gains of 1 and 4. This module provides a maximum number of high-level signal inputs at a minimum cost per input. The tradeoff is that any channel must be driven with low source impedance. For high source impedance driving use other available modules.

MODULE BUS ADDRESSING:

The module address is defined as:

0, 0, 0, 0, 0, 0, MA_9, MA_8, MA_7, MA_6, MA_5, MA_4, MA_3, MA_2, MA_1, MA_0

NOTE: MA_9, MA_8, MA_7, MA_6, and MA_5 are strapped at the connector

(Connect to MA_STP for a 1, don't connect for a 0)

The module's base module address is strap programmable at the connector (5 bits). The Module Address (MA) can be strap programmed to any 16 bit address which a DAU implements in the CAIS normal mode address space on page's 0 or 1 only (This means the 6 MSB's of the 16-bit address are not strapped and assumed zero). The five LSB's of the module address are not strapped so that the possible base module address's occur at integer multiples of 32. The five LSB's define which of the 32 analog inputs is selected.

During data acquisition, 32 addresses are used in the CAIS normal mode address space starting at the strap programmable base module address. For each address, one high level differential analog input is multiplexed onto the DAU's analog bus for A/D conversion.

CONFIGURATION ID'S:

For gain=1: 80C1 hex

For gain=4: 80C4 hex

3. QTI/CSE64 MODULE

Description:

The QTI/CSE64 module performs the multiplexing of 64 high level single ended analog inputs and provides overvoltage protection of ±30 volts on each input. Signals of up to ±10 volts can be input to this module. The module can be ordered with 2 standard fixed gains of 1 and 4. This module provides a maximum number of high-level signal inputs at a minimum cost per input. The tradeoff is that any channel must be driven with low source impedance. For high source impedance driving use other available modules.

Module Bus Addressing:

The module address is defined as:

0, 0, 0, 0, 0, 0, MA_9, MA_8, MA_7, MA_6, MA_5, MA_4, MA_3, MA_2, MA_1, MA_0

NOTE: MA_9, MA_8, MA_7, and MA_6 are strapped at the connector (Connect to MA_STP for a 1, don't connect for a 0)

The module's base module address is strap programmable at the connector (4 bits). The Module Address (MA) can be strap programmed to any 16 bit address which a DAU implements in the CAIS normal mode address space on page's 0 or 1 only (This means the 6 MSB's of the 16 bit address are not strapped and assumed zero). The six LSB's of the module address are not strapped so that the possible base module address's occur at integer multiples of 64. The six LSB's define which of the 64 analog inputs is selected.

During data acquisition, 64 addresses are used in the CAIS normal mode address space starting at the strap programmable base module address. For each address, one high level single ended analog input is multiplexed onto the DAU's analog bus for A/D conversion.

4. QTI/CSE16F6 MODULE

Description:

The QTI/CSE16F6 module performs the multiplexing of 16 high level single ended analog inputs and provides 16 anti_alaising 6 pole low pass filters on each input. Filter frequencies are available from 10 Hz to 20 kHz. The module can be ordered with standard filter frequencies of 10 Hz, 20 Hz, 50 Hz, 100 Hz, 200 Hz, 500 Hz, 1 kHz, 2 kHz, 5 kHz, 10 kHz, and 20 kHz. Filter frequencies are fixed. Filter frequencies can be set unique on 2 banks of 8 inputs. The module can be ordered with standard fixed gains of 1 or 4. Gains can be set unique on 2 banks of 8 inputs. Signals of up to +- 10 volts can be input to this module. Overvoltage protection of +- 30 volts on each input is provided.

MODULE BUS ADDRESSING:

The module address is defined by:

0, 0, 0, 0, 0, 0, MA_9, MA_8, MA_7, MA_6, MA_5, MA_4, MA_3, MA_2, MA_1, 0

NOTE: MA_9, MA_8, MA_7, MA_6, and MA_5 are strapped at the connector

(Connect to MA_STP for a 1, don't connect for a 0)

The module's base module address is strap programmable at the connector (5 bits). The Module Address (MA) can be strap programmed to any 16 bit address which a DAU implements in the CAIS normal Mode Address space on page's 0 or 1 only (This means the 6 MSB's of the 16 bit address are not strapped and assumed zero). The five LSB's of the module address are not strapped so that the possible base module address's occur at integer multiples of 32. The five LSB's define which of the 16 analog inputs is selected. Note that the LSB of the 16-bit address, which a DAU implements in the CAIS normal mode address space is, assumed zero. This causes a 32-address space to be used where only the 16 even addresses are valid within this space. This was done to save an extra decoding chip since the board layout was tight.

During data acquisition, 32 addresses are used in the CAIS normal mode address space starting at the strap programmable base module address. For each even address, one high level filtered analog input is multiplexed onto the DAU's analog bus for A/D conversion.

Description:

The QTI/CBI96 module excepts up to 96 bilevel inputs.

Thresholds: 3.3 Volt CMOS with ± 25 Volt overvoltage protection,

5 Volt CMOS with ± 50 Volt overvoltage protection, or

10 Volt CMOS with ± 100 Volt overvoltage protection.

A floating input is encoded to a logical zero.

MODULE BUS ADDRESSING:

The module's base module address is software programmable (not strapped at the connector). The module uses its CONFIGURATION ID as its module address during power up initialization to receive its software programmable module address to be used during data acquisition. For this reason, each module attached to a DAU's module bus must have a unique Configuration ID. Sixteen Configuration ID's are provided from 0010 to 001F hex.

The Modules Address (MA) can be software programmed to any 16-bit address which DAU implements in the CAIS normal mode address space. However, the three LSB's of the module address must be zero so that the possible module address's occur at integer multiples of eight.

During data acquisition, eight addresses are used in the CAIS normal mode (module bus) address space starting at the software programmable base Module Address. For each address, sixteen Bilevel inputs are sampled and latched. The eight addresses and inputs are defined below:

MA BI [15:0] 16 Bilevel bits, BI15 down to BI0

MA+1 BI [31:16] 16 Bilevel bits, BI31 down to BI16

MA+2 BI [47:32]

MA+3 BI [63:48]

MA+4 BI [79:64]

MA+5 BI [95:80]

MA+6 BI [35:32], BI [19:16], BI [3:0], 0,0,0,0

MA+7 BI [83:80], BI [67:64], BI [51:48], 0,0,0,0

Notes: 1) MA means Module Address (Software Programmable).

2) For 12 bit CAIS BUS reply words, the 4 LSB's are truncated.

6. QTI/CITIMB MODULE

Description:

The QTI/CITIMB module provides IRIG B timing capability. The IRIG B electronics synchronizes with an external IRIG B input after the signal has been applied to the input for a maximum of 10 seconds. When the external signal is removed the unit will maintain IRIG Time consistent with the drift rate specifications of the internal oscillator. A reset time signal is available at the J1 connector (Grounding this pin will reset the time).

MODULE BUS ADDRESSING:

Several addresses in the CAIS normal mode are reserved for dedicated address decoding. The IRIG Time module uses dedicated addresses. The dedicated addresses are all at the end of page 1. The IRIG B module dedicated addresses are tabulated below:

*NOTE:

1. Freeze indicates to the DAU to latch the free running IRIG time value. the IRIG B time word is 64 bits long and latching all 64 bits allows for multiple CAIS bus reads of time value that occurred when latched.
2. Timecode Bits read depend on CAIS Bus reply bits per word
3. The 64 bit timecode word is defined as TIMECODE[63:0] below:
