VXI
VXI stands for VME eXtensions for Instrumentation. It is an open standard first developed by five leading Test and Measurement companies in 1987 to standardise a backplane capable of developing open, interchangeable instrument modules that could be used to build Automatic Test Equipment (ATE).Data Patterns designs and markets a wide range of VXI modules, some of which are listed below. Due to the use of the latest technologies, Data Patterns VXI modules offer the highest I/O density available in the industry today.Further enhancements of functional capabilities are achieved by the use of VXI IP carriers and VXI M Module carriers. This extends standard functions available from Data Patterns in these mezzanine architectures to the VXI platform.

128 Channel Isolated Digital Input / Interrupt Module
DP-VXI-3117
DP VXI 3117 provides 128 isolated channel digital inputs for sensing DC levels and edge transitions of upto 48VDC. The input level selection for 5 (TTL / CMOS compatible), 12, 24 or 48V is made through on-board jumper selection. The debounce feature is programmable for a period of 2msec to 2147 sec. in binary increments. Channel groups 1 to 32, 33 to 64, 65 to 96 and 97 to 128 can each have a unique programmed debounce period, provided the ratio of clock period between groups does not exceed 32,768.

80 Channel Relay Multiplexer
DP-VXI-4017
DP-VXI-4017 is an 80 Channel Relay Multiplexer constructed using ‘2 Form A’ (DPST) relays. It is a ‘C’ size 1 slot register based VXI module. This 80 Channel Relay Multiplexer module is highly configurable. As an 80 channel multiplexer, one input can be multiplexed to any of the 80 outputs or vice versa. The 80 channel multiplexer is divided into 8 banks of 10 channels each. This combination allows the board to be used as one group of 80x1 or two groups of 40x1 or four groups of 20x1 or eight groups of 10x1 differential multiplexer. The banks are isolated from each other by tree switches. 8 tree switches are used, one tree switch for each bank. A common tree switch is used to group all the eight banks. For short circuit protection resistors are provided for all the common terminals.

80 Channel Relay Switch
DP-VXI-4503
DP-VXI-4503 is a 80 channel, one Form C (SPDT) relay switch designed as a C size VXI module. This high density switch module is designed with a register based interface occupying only one VXI slot. This module uses two Form ‘C’ relay switches. Out of the two contacts in each relay, one is used to provide the status of the relay through read back and the other is used for switching purpose.The user can write the command for the selected channels on to the primary latch of the FPGA section. Readback is available to confirm the selected commands. On command, the data from the primary latch is transferred to the secondary latch. The relay driver section provides the necessary drive to switch ON the relays. The buffers in this section drive the relay coils.This module features a back plane trigger for VXI triggered operation. On receipt of the back plane trigger the programmed relays will be energised/de-energised. Alternatively, software trigger can be used.

32 Channel Analog Comparator Module
DP-VXI-5106
DP-VXI-5106, is a 32 Channel Analog Comparator Module with 32 channels of differential analog window comparators. Each channel is provided with a window comparator as well as a Level Comparator , software selectable on an independent channel basis. All the 32 channels have been grouped into four groups of 8 channels each. This allows the user to configure the comparator module based on the application to initiate alarm action to exactly meet application requirements. Each Comparator channel can be programmed to generate a VXI bus interrupt or can be masked through software. An Interrupt is generated on an individual channel basis or on a group basis. Front panel outputs of buffered TTL and a 2-CO relay contact is available for every group (4 outputs total each). Also, a common buffered TTL interrupt output and a common 2-CO relay contact is also available at the facia providing extensive flexibility in application engineering.This module is an ideal device for GO / NO-GO testing in Test Stand Automation where important signals must be continuously monitored for system shut down purposes and safety inter-lock implementation. The hardware implementation in the Comparator module provides high-speed throughput and reliable inter-lock implementation. The interrupt out signal can be further wired as trigger signals for pre and post trigger analysis of signal data for post acquisition detailing.Each channel provides a Window Comparator implementation and a Level Comparator implementation. The configuration is programmable through software and the alarm can be generated if the signal is within the window or outside the window. Similarly, a high and low limit can be set and a trigger is generated if the signal exceeds the high limit or drops below the low limit.
