The Abaco Systems IP-Universal Serial is a single-wide IndustryPack module delivering dual high-speed multiprotocol serial communication interfaces. Each port independently supports EIA-232, EIA-422, and EIA-485 standards, enabling flexible connectivity across industrial and embedded platforms. The module uses dual Zilog Z16C30 Universal Multi-Protocol Serial Controllers (USC), each with four 32-byte FIFO buffers per channel to optimize throughput and stream management.

Technical Specifications

• Ports: 2 independent high-speed multiprotocol serial ports
• Serial Standards: EIA-232, EIA-422, EIA-485
• Protocols: SDLC, HDLC, Bisynchronous (BiSync), NRZ, NRZI, Biphase, MIL-STD-1553B
• Controller: Zilog Z16C30 USC with independent baud rate generators, phase-locked loop circuits, vector registers, and interrupt controllers per channel
• FIFO Buffers: Four 32-byte buffers per channel
• Data Rates: Up to 10 Mb/s synchronous with external clock
• Oscillator: On-board 3.6864 MHz; supports user-supplied oscillator for non-standard rates
• External Clock Lines: Four available for full-duplex synchronous operation
• Transmit Clock: Programmable input or output; Receive Clock: input-only
• Error Detection: 16-bit and 32-bit CRC generation and checking
• Character Configuration: 1 to 8 bits per character plus one address/data bit
• Synchronous Features: Sync stripping, preamble generation, digital phase-locked loop for clock recovery

– Key Features

• Dual independent channels enable simultaneous, distinct operations on each port
• RS-485 compatibility via software-controlled transceiver switching on TxD lines
• Full handshake and clock signal sets on each port
• Configurable transmit clock direction accommodates various synchronous topologies

– Typical Applications

Multiprotocol serial I/O in avionics, military systems, telecommunications, industrial automation, and embedded defense platforms requiring deterministic, simultaneous dual-channel communication.
