IO581: RS-232/RS-422/RS-485 Serial I/O Module

4-port serial I/O module supporting RS-232, RS-422 and RS-485, with Simulink driver blocks

IO581 is a very versatile asynchronous serial module which supports RS-232, RS-422, and RS-485 on each of its 4 ports. The module also supports very high baud rates, especially for RS-422 and RS-485. The Simulink Real-Time driver blockset for this module offers a composite Send/Receive block as well as low-level setup, send, receive, FIFO, status, and utility blocks.

4 independent serial ports
Supports RS-232, RS-422 full-duplex, RS-485 half-duplex
RS-232 baud rates up to 1Mb/s
RS-422/RS-485 baud rates up to 10Mb/s
RS-422/RS-485 termination resistors can be installed for each port pair on request

20581X	IO581	1 x IO581 I/O module Driver block library for Simulink Real-Time™ Installation into real-time target machine Note: the default configuration is for RS-232 on all four ports (no termination resistors installed). For RS-422 or RS-485, the user must install the corresponding termination resistors externally. Alternatively, Speedgoat can install the termination resistors for each channel pair during assembly. In this case, the serial communication protocol must be defined prior to order.

Key to X in Item ID
