These modules provide an asynchronous serial communication interface for your system. The IP502 has four asynchronous, half-duplex RS485 serial ports. It provides a cost-efficient interface to RS485 multi-driver networks which support up to 32 nodes. However, for full handshaking support, use the full duplex IP501.

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-character FIFO buffers on the transmit and receive lines.

Specifications

RS485 Serial Ports

Configuration: Four independent, non-isolated RS485 serial ports with a common single return connection.
Data rate: Programmable up to 512Kbps using internal baud rate generator and carrier 8MHz clock. Consult factory for custom baud rates up to 1M baud.
Interface: Asynchronous serial only.
Max. cable length: 1200 meters (4000 feet) typical. A signal repeater can extend this limit.
Character size: 5 to 8 bits, software-programmable.
Parity: Odd, even, or no parity; software-programmable.
Stop bits: 1, 1-1/2, or 2 bits; software-programmable.
Data register buffers: 16-byte receive FIFO buffers and 16-byte transmit FIFO buffers.
Interrupts: Receiver line status (overrun error, parity error, framing error, or break interrupt); received data available (FIFO level reached) or character time-out; transmitter holding register empty. Multiple ports share the IntReq0 line according to a shifting priority scheme based on the last interrupting port serviced.

UART

UART: Texas Instruments TL16C554FN.

IP Compliance (ANSI/VITA 4)

  • Description

    These adapters repeat field I/O connections on Acromag’s carrier cards for front or rear exit from the card cage.

    Transition modules provide a solution for controlling the location of your cabling within the card cage.

    TRANS-200: Transition module
    Transition module for AVME9670 board. See AVME9670 manual for more information.

    VPX4500-RTM-LF: Rear transition module used with both the VPX4500E-LF and the VPX4500-CC-LF carriers to provide access to the slot C AcroPack field I/O signals. See carrier card user manual for more information
