IP501: Serial Communication, 422/485 Full Duplex Industry Pack Module

IP501: Serial Communication, 422/485 Full Duplex Industry Pack Module Description

These modules provide an asynchronous serial communication interface for your system. They have four asynchronous, full-duplex RS422B serial ports. Since the transceivers are compatible with the RS485 standard, you can also use a full-duplex RS485 interface for multiple driver support. However, for true half duplex RS485 operation, use the IP502.

Software-configuration quickly sets the baud rate, character-size, stop bits, and parity.

For more efficient data processing, each serial port is equipped with 16, 64 or 128-character FIFO buffers on the transmit and receive lines.

Update to AcroPack mezzanine modules into your host system, they maintain the same functionality and memory map of Acromag’s existing Industry Pack (IP) modules. Learn More >

IP501: Serial Communication, 422/485 Full Duplex Industry Pack Module Features & Benefits

• Four asynchronous, full-duplex EIA/TIA-422B serial ports (full-duplex EIA-485 )
• 16, 64, or 128-byte FIFO buffers
• Programmable baud rate (up to 512Kbps) (Consult factory for custom rates up to 1Mbps)
• Individually controlled interrupts (unique vectors for each port)
• Handshake control signals (RTS, CTS) for each channel
• Extended temperature option (-40 to 85°C)
• Industry-standard 16C550 family UART includes software-compatible 16C450 mode
• 0 to 70°C (IP501-16/64/128) or -40 to 85°C (IP501-16E/128E/4861-xE/5024-xE)
•  Failsafe receivers guarantee a high output state when the inputs are left open or floating.
• Internal diagnostics help detect faults.
• FIFO buffers minimize CPU interaction for improved system performance.
