IP502: Serial Communication, 485 Half-Duplex Industry Pack Modules
Please sign in or register to see model options and to add products to your cart.
Product short description:
- Four asynchronous EIA-485 serial ports
- 16-byte FIFO buffers
- Interrupt support
- Programmable baud rate (up to 512Kbps)
Not recommended for new designs. Limited availability - please contact sales department.
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)
Meets IP specifications per ANSI/VITA 4-1995.
IP data transfer cycle types supported: Input/output (IOSel*), ID read (IDSel*).
Access times (8MHz clock):
ID PROM read: 1 wait state (375nS cycle).
Channel register read/write: 2 wait states (500nS cycle).
Interrupt select read: 2 wait states.
Environmental
Operating temperature: 0 to 70°C.
Storage temperature: -40 to 125°C.
Relative humidity: 5 to 95% non-condensing.
Power:
+5V (±5%): 300mA maximum.
±12V (±5%) from P1: 0mA (not used)
MTBF: 7,642,747 hrs at 25°C, MIL-HDBK-217F, Notice 2.
- Four asynchronous, half-duplex EIA-485 serial ports
- 16-byte FIFO buffers
- Programmable baud rate (up to 512Kbps) (Consult factory for custom rates up to 1M bps)
- Individually controlled interrupts (unique vectors for each port)
- Line-break and false start-bit detection
- Industry-standard 16C550 family UART includes software-compatible 16C450 mode
- 0 to 70°C
- Failsafe receivers guarantee a high output state when the inputs are left open or floating.
- Internal diagnostics help detect communication faults.
- 16-byte FIFO buffers minimize CPU interaction for improved system performance.
