R96XFER

The Rockwell eXtended FAXENGINETM R96XFER Set consists of a Rockwell extended Facsimile Controller with reduced drive (XFCR) device and a Rockwell MONOFAX@ Modem device. This family of eXtended FAXENGINE (XFER) devices provides upgradability via its hardware and software compatible controllers. Starting with the basic eXtended Facsimile Controller (XFCR-B), combinations of voice page memory plain paper support and full-duplex speakerphone(- S) support of R96XFER can be added. Voice operation provides minutes of digital telephone answering machine (DTAM) recording. Telephone line rates up to 9600 bps (R96) or 14400 bps (R144) are supported. The XFER R96XFER Set models and the supported major functions are listed in Table 1. Each extended FAXENGINE Device Set, including supplied firmware, comprises a complete facsimile machine controller-needing only a power supply, scanner, printer and paper path components to complete the machine. The FAXENGINE Development System including the FAXENGINE Evaluation System (FEES-X) and the MC24 ROM Emulator (McFERE) provides an effective development environment.

The features of R96XFER can be summarized as (1)microprocessor and bus interface: - Enhanced MC24 central processing unit (CPU) - 10 MHz CPU clock speed - Memory efficient input/output bit manipulation - 24-bit internal address bus - 8-bit data bus; (2)external bus:- address, data, control, status, interrupt, and decoded chip select signals support connection to external ROM, RAM, and optional peripherals - 24-bit external address bus (XFER-B: 20-bit); (3)chip selects:- ROMCSn for ROM support - CSOn for SRAM - CS1n for external peripherals - MCSn for modem - Optional general purpose: CS2n, CS3n, CS4n and CS5n (CS5n is unavailable on the XFCR-B); (4)DRAM Controller (except XFCR-B, XFCR-P) - Supports external page memory - battery-backed refresh with separate battery power; (5)DMA Controller:- Three to six dedicated internal channels for scanner, printer, and T.4/T.6 access of internal and/or external memory- External DMA channel (XFCR-P, XFCR-VP and XFCR-MVP only) - Internal RAM (1K X 8) for shading correction, line buffers and CPU (XFCR-MV, XFCR-MVP only) - external ram up to 1 (XFER-B) or 14 (other) Mbytes - External ROM up to 1 (XFER-B) or 3 (other) Mbytes; (6)interrupt controller; (7)T.4/T.6 compression and decompression in hardware - MH/MR (exceptXFCR-B) - MH/MR/MMR (XFCR-MV, XFCR-MVP only) - alternating compression/decompression (XFCR-MV, XFCR-MVP); (8)motor control for scanner, and printer - four outputs to external current drivers for the scanner motor and four for the printer motor - motor outputs can be programmed as general purpose outputs (GPO) for application with a single motor or plain paper machines; (9)scanner and video control - CCD and CIS scanners supported - six programmable control signals: - four programmable scanner control signals - two video output control signals support external signal pre-processing; (10)B4/A4 scanner support; (11)5 ms minimum line time; (12)line lengths to 4096 pixels; (13)scanner flash A/D Interface - Internal 6-bit flash A/D converter - A/D reference inputs enable external control - video processing - per-pixel and per eight-pixel shading correction - edge enhancement and dynamic background and contrast control - Up to 8x8 programmable dither table - image data processing port allows access to scan data prior to video processing - multi-level B4 to A4 size reduction (except XFCR-B); (14)programmable resolution conversion (see Table 1) - two-dimensional bi-level resolution conversion provides expansion to 200%; reduction to 33% - vertical line ORing - scanner output bit order reversal.

The absolute maximum ratings of R96XFER are (1)operating temperature:0°C to 70°C; (2)storage temperature: -40°C to 80°C; (3)relative humidity: up to 90% noncondensing, or a wet bulb temperature up to 35°C, whichever is less.
