Alpha Data Product : XRM-RS485

XRM-RS485 Overview Block Diagram Specification Ordering Info

Product Features

Multiple RS485 Interface
No software required.

Product Summary

The XRM-RS485 is an I/O Module which provides a Front Panel RS485 Interface.

Enables the FPGA board to communicate with external devices through the RS485 protocol.

Note: To ensure XRMs and XRM2s cannot be inadvertently installed on non-compatible FPGA platform boards the XRM2 connectors are mounted rotated 180° from those on XRM IO Modules. Most photographs of our mature XRM IO Modules are of the XRM version.

XRM I/O

RS485 Data Port

type:	I/O	channels:	19
Information:	provides simple RS485 functionality 19 differential pair I/Os

Battery

The battery is needed for the "AES Bitstream Encryption" capability of the Xilinx^® Devices. It is required to maintain the AES encryption key such that the FPGA can be loaded with an encrypted bitstream. For all applications using this function either the FPGA board or the attached XRM must have the battery facility.

The XRM provides holders for a back-up battery. Uses SR60 or equivalent batteries.
