IP520

Octal Serial 232

Communication

These modules provide eight asynchronous serial

communication ports from a single IP carrier slot.

Software-conguration helps you quickly set baud

rates, character-sizes, stop bits, and parity. Signal sup-

port for RTS/CTS handshaking is also included.

For more ecient data processing, each serial port is

equipped with 64-character FIFO buers on the

transmit and receive lines.

The data ports generate individually controlled

transmit, receive, line status, and data set

interrupts. Since unique interrupt vectors may

be assigned to each port, it is easy for you to

identify and locate the interrupt source. Also,

a priority shifting scheme prevents continuous

interrupts from one port from blocking inter-

rupts from another.

Features

■

64-byte receive FIFO buers

■

Interrupts with unique vectors for each port

■

Programmable baud rate (up to 230Kbps)

Benets

■

High-density design lowers per-port costs and

saves IP carrier card slots for other functions.

■

64-byte FIFO buers minimize CPU interaction for

improved system performance.

■

Each serial channel provides handshake support to

simplify interfacing with modems.

Specications

RS232E Serial Ports

Conguration: Independent, non-isolated serial ports with a

common single return connection and congured as a

DTE device.

internal baud rate generator.

Max. cable length: 15 meters (50 feet) typical, limited to a

cable capacitive load of 2500pF.

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 buers: Double buered or 64-byte FIFO bu-

ered, mode selectable.

Interrupts: Receiver line status (overrun, parity, framing error,

or break interrupt); received data available

(FIFO level reached) or character time-out; transmitter

(FIFO level reached); or modem status (CTS).
