Black Box IC113C, RS-485, IC175C manual Introduction, Features

CHAPTER 2: Introduction

2.3 Features

Listed below are the special features your Serial Interface offers.

•Each port is independently addressable.

•Eleven interrupt options, including AT interrupts, for simple integration into existing systems.

•IRQs (2 [9], 3, 4, 5, 6, 7, 10, 11, 12, and 15) supported.

•IRQs can be shared or individually set for each port.

•Supports Interrupt Sharing—only one interrupt line required for multiple ports.

•Supports any character set defined by binary notation.

•16550 UARTs on the IC113C help ensure against data loss. This chip features programmable baud rate, data format, interrupt control, and a 16-byte FIFO. The IC175C uses 16950 UARTs, which feature a 128-byte buffer for even better performance.

•Faster baud rates—up to 115.2 Kbps (IC113C) or 460.8 kbps and above (IC175C).

•Addressable as COM1: through COM4: or any other address up

to 3FF Hex.

•Support for non-standard baud rates available. These baud rates (such as 31.25K or 76.8K baud) are supported by installing a different oscillator at location Y1. Call Technical Support for more information.
