Description
The X2-Series X2BS10X424 Quad RS-422 / RS-485 expansion board is designed for the Strato Pi Max.
It provides four serial ports individually configurable as full-duplex RS-422 or half-duplex RS-485. The four ports are interfaced to the Compute Module via an integrated FTDI FT4232H hi-speed USB 2.0 converter.
Features
- Four high-speed RS-422/RS-485 interfaces with electrostatic discharge protection, individually configurable via I2C
- Configurable full-duplex (RS-422) / half-duplex (RS-485) modes
- Configurable line termination resistors
- Configurable slew rate limiter
- Configurable local TX echo on RS-485 interfaces
- Front panel LEDs show board power status and channels RX/TX activity
