SBS IP-Universal Serial IndustryPack Module With Two High-Speed Multiprotocol Serial Ports

The GE Fanuc / SBS / Greenspring IP-Universal Serial IndustryPack Module With Two High-Speed Multiprotocol Serial Ports implements two EIA-232/422/485 high speed multiprotocol serial ports, each with a full set of handshake and clock signals. Protocols include SDLC, HDLC, BiSync, NRZ, NRZI, and Biphase. The IP-Universal Serial incorporates the Zilog Z16C30 Universal Multi-Protocol Serial Controller (USC) which includes four 32 byte FIFO buffers. The two channels within the USC are completely independent. Each channel has a baud rate generator, a digital phase-locked loop, a vector register, an interrupt controller, and a protocol controller.

Additional capabilities include 16 and 32-bit CRC generation and checking, one to eight bits per character, one address/data bit, MIL STD 1553B protocol support, sync stripping, preamble generation, and digital phase-locked loop circuits for clock recovery. The IP-Universal Serial includes an on board 3.6864 MHz oscillator to provide all of the standard baud rates. A separate location is provided on the IndustryPack for a user-supplied oscillator to allow non-standard baud rates. The I/O interface provides four external clock lines to permit full duplex synchronous operation on both channels. The interface includes an external transmit or receive clock on one channel. Independent interrupt vectors and controls are provided for each IP-Universal Serial channel.
