IndustryPack Compatible Bi-Directional Serial Data Interface

Please refer to the IP-BiSerial-IO page for the base card description. IP-BiSerial-IO

The standard interface offers Ready, Data, Clock and Strobe. The programmable output rates and a user oscillator position allow for flexible frequency selection. RS422/485 and TTL compatibility will interface to a variety of systems. If your situation demands a custom application then we will update the Xilinx FPGA. Send us your timing and we will send you the interface.... email us your wish list or call today!

The NG4 version of the IP-BiSerial-IO is designated IP-BiSerial-NG4. The -NG4 has a custom Xilinx implementation which allows the user to control the width of the synchronization pulse, the time delay after the sync and the start of data, and the time between data words. The word transfer has an associated Word Sync signal to provide for framing and error checking. The Frame sync signal provides for message level synchronization. In addition to the programmable delays, the base frequency is also programmable. The NG4 is an update from the NG2. The new features include a 50 MHz reference oscillator, no parity option, receive all option, 3 and 4 wire modes. 4 Wire mode with parity checking/generation enabled and odd selected with 512 KHz is the NG2 standard mode.

IP-BiSerial-ENG-1..........Engineering Kit includes Board level Schematics [PDF], Reference Software [PCI3IP, WIN NT, WinRT, Visual C environment - ZIP file], IP-DEBUG-BUS, IP-DEBUG-IO. Purchase this kit once to support IP-BiSerial and other IndustryPack development. Ask about our -3 and -5 kits which include a PCI carrier.

Frame and Word sync plus the synchronous clock control data flow. T1, T2, and T3 are programmable: Frame asserted, Frame to Word, and the inter-word gap. The delays are based on the transmitter reference rate.

A range of frequencies is available based on the on-board oscillator or IP clock references [50 MHz]. A programmable divider is provided to support frequency selection. Programmable active edge of clock. For more details please download the manual.

The data is transmitted in 32 bit data packets with or without parity appended. The MSB is transmitted first, parity last. Programmable received word count with the option for all words independent of count. The transmitter sends data until the FIFO is emptied for "any length" messages. At the end of transmission, or when the programmed number of words is received interrupts can be generated. The Programmable Almost Full Flag and Programmable Almost Empty Flag interrupts can be used with the Receiver and Transmitter to support long transfers. 32K x 16 FIFO receive and transmit on the -NG4 model.

The receive channel checks for Parity, Frame, and Over-run errors. Parity is programmable Odd, Even, or none. The Frame detector checks the Frame and Word sync signals to determine if the channel has lost synchronization. Only Word Sync is used in 3 wire mode. The error is asserted if sync is lost. The over-run error occurs if the Receive FIFO is full when it is time to write data to that port.

The NG4 version of the BiSerial board supports both 8 and 32 MHz IP Bus operation. The FIFO can be written with IO or Mem space accesses. With a carrier supporting 32 bit conversion the FIFOs can be loaded and unloaded at 32 MHz using 32 bit data transfers. See the PCI3IP and PCI5IP.
