Description
779891-03 NI 9870 is a C Series Serial Interface Module that adds four RS232 ports to CompactRIO frameworks, offering flexibility for communication with serial devices. With individual buffers on each port, this module saves FPGA space and rearranges programming, while supporting baud rates up to 921.6 kbit/s for fast data transfer speeds.
779891-03 NI 9870, 4 Port RS 232 Serial Module, Conformal Coating National Instruments NI-9870 C Series Serial Interface Module adds serial RS232 ports to CompactRIO frameworks. With individual 64 B buffers on each port that save CompactRIO FPGA space and rearrange programming, this module offers users flexibility when communicating with serial devices. The device features four full-featured, independent RS232 DTE ports that are isolated from other modules in the system, each fully compatible with ANSI/EIA/TIA-232 standards. This C Series module supports standard settings and baud rates up to 921.6 kbit/s per port, allowing data transfer speeds of up to 2 Mbit per second between modules and CompactRIO. With a power consumption of 0.5 W maximum when active and 50 µW in sleep mode, the NI 9870 also comes with 4 RS232 (TIA/EIA-232) or 4 RS485/RS422 serial ports, baud rates from 14 bit/s to 921.6 kbit/s, and a PC-MF4-PT cable included. Running on NI-RIO driver software, the NI 9870 is compatible with software packages like LabVIEW development system, LabVIEW FPGA module, Visual C#, or Visual C++. Weighing 5.4 oz, the device has a recommended operating temperature range of -40 °C to 70 °C, a storage temperature range of -40 °C to 85 °C, and random and sinusoidal operating vibration of 5 grms and 5g, respectively, at a frequency range of 10 to 500 Hz.

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.
