Industry Pack Modules Industry Pack Modules IP501-x Serial 422/485 Communication 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 Large, 128-byte FIFO buers reduce the processing burden on the CPU to increase the overall system performance. standard, you can also use a full-duplex RS485 interface for multiple driver support. However, for true half- Specications Ordering Information duplex RS485 operation, use the IP502. RS422B Serial Ports Industry Pack Modules Conguration: Four independent, non-isolated RS422B serial Software-conguration quickly sets the baud rate, IP501-16: Four serial ports with 16-byte FIFOs. ports with a common single return connection. character-size, stop bits, and parity. IP501-16E: Same as IP501-16 plus extended temp. range Data rate: Programmable up to 512K bits/second using IP501-64: Four serial ports with 64-byte FIFOs internal baud rate generator. Consult factory for custom For more ecient data processing, each serial port is baud rates up to 1M baud. IP501-128: Four serial ports with 128-byte FIFOs equipped with 16, 64 or 128-character FIFO buers on Interface: Asynchronous serial only. IP501-128E: Same as IP501-128 plus extended temp. range the transmit and receive lines. Character size: 5 to 8 bits, software-programmable. Acromag oers a wide selection of Industry Pack Carrier Cards. Parity: Odd, even, or no parity; software-programmable. Features Stop bits: 1, 1-1/2, or 2 bits; software-programmable.  Four asynchronous, full-duplex RS422B serial ports Software Interrupts: Receiver line status (overrun error, parity error, IPSW-API-VXW (full-duplex RS485 ) framing error, or break interrupt); received data available ® VxWorks software support package (FIFO level reached) or character time-out; transmitter  16, 64, or 128-byte FIFO buers IPSW-API-WIN32 holding register empty; or modem status (CTS). Multiple ® 32-bit Windows DLL driver software support package  Programmable baud rate (up to 512Kbps) ports share the IntReq0 line according to a shifting priority IPSW-API-WIN64 scheme based on the last interrupting port serviced. (Consult factory for custom rates up to 1Mbps) ® 64-bit Windows DLL driver software support package UART  Individually controlled interrupts Accessories IP501-16: Texas Inst. TL16C554FN or equivalent. (unique vectors for each port) See www.acromag.com for more information IP501-64: Startech ST16C654CJ68.  Handshake control signals (RTS, CTS) IP501-128: Exar/Startech XR16C854 for each channel IP Compliance (ANSI/VITA 4)  Extended temperature option (-40 to 85°C) Meets IP specications per ANSI/VITA 4-1995. IP data transfer cycle types supported:  Industry-standard 16C550 family UART includes Input/output (IOSel*), ID read (IDSel*). software-compatible 16C450 mode Access times (8MHz clock): ID PROM read: 1 wait state (375nS cycle). Channel register read/write: 2 wait states (500nS Benets cycle).  Failsafe receivers guarantee a high output state when Interrupt select read: 2 wait states. the inputs are left open or oating. Environmental  Internal diagnostics help detect faults. Operating temperature: 0 to 70°C (IP501-16/64/128) or -40 to 85°C (IP501-16E/128E/4861-xE/5024-xE).  FIFO buers minimize CPU interaction for improved Storage temperature: -40 to 125°C (all models). system performance. Relative humidity: 5 to 95% non-condensing. Power: +5V (±5%): 650mA maximum. ±12V (±5%) from P1: 0mA (not used). MTBF: 7,150,212 hrs at 25°C, MIL-HDBK-217F, Notice 2.. All trademarks are the property of their respective owners.
