Description

This LPC FMC card has eight channels, RS-xxx interfaces. The Channels are factory-defined/built when ordering the board.
Possible combinations/interfaces are: X * RS232 + Y * RS422 + Z * RS485 where X+Y+Z = 8 ( for 8 channels ).
When ordering FMC-RSxxx-8, a customer needs to define X, Y, and Z.

The module can also be used as a PMOD interface. Please see the 4 block diagrams for potential combinations.

There is a breakout board and cable assembly that allows the ports to be accessed via DB9 connector.

Features

  • RS422 or RS485 or RS232 input interfaces – orderable option, separate for each channel;
  • All output interfaces are ESD protected, ESD protection built-in IC;
  • THE main IC is SP339EER1-L;
  • Total eight channels of RSxxx interfaces routed to Samtec right angle ERF8-020-01-L-D-RA-L-TR connector;
  • Can order breakout board and cable assembly for easy access to channels via DB9 connectors.
  • Supported VADJ levels 1.2V – 3.3V;
