Installing the Card

PCIe, cPCI, VPX, PMC: Card Installation

Caution: Always work at an ESD protected workstation, wearing a grounded wrist-strap.

  1. Shut the computer down, then turn OFF its power switch, and unplug the line cord. Open the computer chassis.
  2. Remove the TSync card from the shipping envelope.
  3. Remove the blank computer bracket from the empty slot, and insert the TSync card instead. Attach the top of the TSync bracket with the screw from the metal plate.
  4. PMC:

    Position the card with the standoffs facing the host (carrier) board, and with the I/O-connector oriented toward the front panel. Align the two PCI connectors located at the end of the TSync card opposite the I/O-connector with the mating connectors on the host board, and carefully press the card into position on the host. Verify that the PCI connectors have mated completely and that the standoffs are seated against the host board.

    Attach the card to the host with four 2.5 x 6.5 mm panhead screws. Pass the screws through the back of the host into the four mounting holes on the board. Tighten the screws carefully to complete the installation. Do not overtighten.

  1. Close the computer, plug in the line cord, and start the computer. Depending on which operating system is used, a message that identifies new hardware may appear. This message may indicate that the hardware is of "unknown type". This is normal. Exit the "Found New Hardware" dialog box.

Note: Once an external GNSS receiver is connected to a cPCI or PCIe card, it will be reset to factory default settings.
If you are replacing an existing legacy board-level product, be aware that your GNSS receiver will no longer operate with legacy board-level products once it has been used with a TSync-cPCI or PCIe board.

PCI-104: Card Installation

Caution: Always work at an ESD protected workstation, wearing a grounded wrist-strap.

  1. Turn off power to the PCI-104 system.
  2. Select the stand-offs for the desired stack height, and install them (not included).
  3. Remove the TSync PCI-104 card from its anti-static bag.
  4. Check that the pins of the bus connector are properly positioned.
  5. Verify the stacking order. Make sure all of the buses used by the peripheral cards are connected to the CPU-module.
  6. Hold the card by its edges and orient it such that the bus connector pins line up with the matching connector on the stack.
  7. Carefully and evenly press the card onto the PCI-104 stack.
  8. If other cards are to be stacked on top of this unit, install them.
  9. Attach any necessary cables.
  10. Set the DIP switch in accordance with the card's stack position (see PCI-104 Configuration (DIP Switch)).
  11. Re-connect the power cord and apply power to the stack.
  12. Boot the system and verify that all of the hardware is working correctly.


The TSync card operates automatically as soon as the host computer system performs the power-on reset. To change the operating parameters or read data, consult the available Application Programmer’s Guide for this product.
