VME ATM card

ATM-to-RS232 VME Card

The AtA-4RS232 is a single-slot 6Ux160 VME card which provides four RS232/485 channels, voltage, temperature,and humidity monitors, and a signal generator with interfaces to an ATM network. The card functions include an AAL processor, 155 Mbit/s ATM-SONET OC-3c fiber optic interface, selectable RS-232/485 serial ports, programmable signal generator, temperature sensor, humidity sensor, and VME backplane voltage sensors. The card can be used for general purpose interface, control, system monitoring, and calibration in sensor networks and data acquisition systems. The card includes an embedded diagnostic signal generator for card and network test, status LEDs, and a timing input port for optional synchronization or time-tagging. The card is compatible with commercially available ATM switches, interface cards, and test equipment.

The PSI ATM-to-FPDP Card provides a data bridge between an ATM-SONET OC-3c network port and an FPDP bus. The card can be configured to move data from FPDP to ATM (FPDP-IN) or from ATM to FPDP(FPDP-OUT). When configured as FPDP-IN, the card captures FPDP frames with a FIFO/RAM memory buffer, formats the data into AAL5 PDUs with a processor, and transmits the data via an ATM-SONET OC-3c fiber optic interface. When configured as FPDP-OUT, the card does the reverse process: it receives ATM-SONET AAL5 PDUs from the network and puts the data into memory, formats the data into FPDP frames, and transmits the frames via the FPDP bus.

TAXI-FPDP VME Card

The TAXI-to-FPDP Card is a single slot 6U VME card which converts TAXI fiber optic telemetry to FPDP data. FPDP output data can be received on any one of the TAXI RX ports or inverse multiplexed across 2 or 3 RX ports. The TAXI TX ports can be used for transmitting controls or timing. A hardware sync pulse output, synchronized to RX port data, provides an optional mechanism to synchronize external systems or multiple TAXI-to-FPDP cards. An Ethernet network interface provides a TCP/IP link to an embedded web page server which provides HTML web-based monitoring and control of the card. The web page functions include monitoring of TAXI-link errors, data-format errors, and command errors, as well as card control.

The PSI Timing Transmitter (AtA-TTX) VME card provides for fiber optic distribution of timing signals in applications such as sensor networks and remote data acquisition. The card has two clock inputs (T1, T2) on BNC connectors for connection to a master clock source (e.g., GPS Clock Receiver) and up to 8 fiber optic outputs for the transmission of the clocks. On-board programmable logic, phase-lock-loops, and selectable delay elements provide custom frequency synthesis and clock edge crafting.

The Timing Receiver (AtA-TRX) VME card provides a high-performance solution for fiber optic distribution of timing clocks in applications such as sensor networks and data acquisition. Intended for use in conjunction with the AtA-TTX card and Analog-to-ATM TM (AtA) A/D cards, the Timing Receiver card provides  2 fiber optic receiver ports, low jitter phase lock loops, clock multiplication, clock frequency synthesis, and three timing port outputs. On-board programmable logic, phase-lock-loops, and selectable delay elements provide custom frequency synthesis and clock edge crafting.
