IP-BiSerial-NG4 Dynamic Engineering Bi-Directional Serial Data Interface

The Dynamic Engineering IP-BiSerial-NG4 Bi-Directional Serial Data Interface is part of the IP Module family of modular I/O components. The IP-BiSerial-NG4 is capable of providing multiple serial protocols. The standard protocol implemented provides a Data, Clock and Strobe interface with Ready control. The –NG4 version is a custom modification featuring two protocols, the use of synchronization signals, 32 bit data with programmable parity, delays and edge definitions.

The IP-BiSerial-NG4 supports both 8 and 32 MHz IP Bus operation. The IP Clock and on-board oscillator are used to derive the reference clocks for the serial operation. Please be sure to select the proper clock divisors and source selector after reset to insure proper operation. Both single ended and differential I/O are available on the serial signals. The differential drivers and receivers conform to the RS-485 specification (exceeds RS-422). The RS-485 input signals are terminated with 180Ω. The single ended driver signal is characterized as an open drain driver with 24 mA of sink. For convenience A 2KΩ pull-up is supplied on board, for faster termination a second pull-up can be added at the receiving end of the circuit. Single ended signals are received through 33Ω resistors. Care should be taken with the single ended signals, as transients can damage the board.

The IP-BiSerial-NG4 conforms to the VITA standard. This guarantees compatibility with multiple IP Carrier boards. Since the IP maintains plug and software compatibility while mounted on different form factors, system prototyping may be done on one IP Carrier board, with final system implementation done on a different one.
