777590-02 VME-PXI8015, XP/2000/NT/Me/98, PXI-8320, VME-MXI-2, MXI-2 Cable National Instruments PXI-8320 Circuit Board is a 32-bit 3U style CompactPCI compatible module that connects the user’s PXI/CompactPCI-based PC to the MXIbus. It can function as the MXIbus System Controller, provide ending resistor networks for daisy-chaining, and share up to 16 MB of DRAM with the MXIbus and VXI/VMEbus.
777590-02 VME-PXI8015, XP/2000/NT/Me/98, PXI-8320, VME-MXI-2, MXI-2 Cable National Instruments PXI-8320 Circuit Board is a 32-bit 3U style CompactPCI compatible module that plugs into a PXI or CompactPCI frame's peripheral slot. This board connects the users PXI/CompactPCI-based PC to the MXIbus and vice versa. It can also function as the MXIbus System Controller and can end the MXIbus signals specifically on the PXI-8320. Additionally, it allows for up to 16 MB of locally available DRAM to be shared with the MXIbus and VXI/VMEbus or used as a dedicated data buffer. The PXI-8320 features a locally available EEPROM with factory and user configuration halves, enabling customization while preserving default settings. To properly terminate the MXIbus daisy-chain, the first and last devices need an end configuration, which the PXI-8320 can provide with ending resistor networks. For those who need the PXI-8320 as the first or last device in the MXIbus daisy-chain, internal resistor terminators should remain in place. Despite being announced as obsolete by National Instruments, the PXI-8320 will continue to be available for purchase and repairs through Apex Waves.

Distribution Cache Shipping Info and Options
Shipping Carriers: Here at Distribution Cache we ship using UPS, FedEx, DHL, or TNT. In most cases we get very competitive rates based on our volume and will be happy quote shipping cost to your location upon request. We also know that many customers would prefer to ship collect on their own account numbers and welcome this option.
Shipping Blind: We recognize that many of our customers intend to re-sell the product to their end user. We respect our customer’s relationships with their clients and offer blind shipping as an option to ensure that the package arrives in the most clandestine way possible.
Shipping Process: We take pride in the way we package your order and spare no cost in making sure that it arrives safely at your facility. In the case of new parts, we are always sure to package the factory box inside another larger box for safe transit. For reconditioned parts we often use Distribution Cache customized packaging that is specially made to protect the products from the bumps and falls present during shipment.
Shipping Options:
Next Day Air Early AM - This service is the fastest overnight delivery option available. For most locations the package will be guaranteed by 8:30AM.
Next Day Air – This service guarantees delivery by 10:30AM and is the most frequently used option for overnight shipments.
Next Day Air Saver – This cost saving overnight alternative guarantees delivery by 3PM the next day.
2nd Day Air – For domestic shipments that would take 3-5 days if shipped via Ground, sometimes having the order in 2 days is a great way to go
Ground – Ground is the most inexpensive shipping option provided. Please ask if we are doing a “free domestic ground” shipping promotion on your order. We often provide free ground shipping on larger orders.
Emergency Courier – At times we can help work with a courier service to get the part to your facility during downtimes scenarios. We prefer that the customer sets up the courier but we can be there to make sure the product is handed off to the driver. Please give us a call to see if this is an option on your order.
Please Note: Products listed as “ships today” can ship same-day if an order is placed before 4PM. For larger drives and motors we ask that notification for same-day shipments be provided by 2PM at the latest. For any products listed as “ships in 3-5 days”, please give us a call to see if this can be expedited.
Question:
What is the model number and main function of the described National Instruments circuit board?
Answer:
The model number is 777590-02, and its main function is to serve as a 32-bit 3U style CompactPCI compatible module that connects a PXI/CompactPCI-based PC to the MXIbus and vice versa. It can also function as the MXIbus System Controller.
Question:
What types of memory are available on the PXI-8320 circuit board?
Answer:
The PXI-8320 circuit board features up to 16 MB of locally available DRAM that can be shared with the MXIbus and VXI/VMEbus or used as a dedicated data buffer. It also has a locally available EEPROM with factory and user configuration halves.
Question:
How does the PXI-8320 terminate MXIbus signals and why is this important?
Answer:
The PXI-8320 can terminate the MXIbus signals with ending resistor networks. This is important because to properly terminate the MXIbus daisy-chain, the first and last devices need an end configuration to prevent signal reflections.
Question:
What should be done with the internal resistor terminators on the PXI-8320 when it is used as the first or last device in the MXIbus daisy-chain?
Answer:
When the PXI-8320 is used as the first or last device in the MXIbus daisy-chain, the internal resistor terminators should remain in place to provide proper termination.
Question:
Although the PXI-8320 has been announced as obsolete, can it still be purchased or repaired?
Answer:
Yes, despite being announced as obsolete by National Instruments, the PXI-8320 will continue to be available for purchase and repairs through Apex Waves.
