1.1 Power requirements

The power requirements and the need for an external power supply depend on the particular card.

TimeTagger4 (all variants)

No external power supply is necessary. Power is supplied by the USB4 port.

xTDC4

An external power supply providing 14–15 V DC @ 45 W is necessary.

xHPTDC8

An external power supply providing 14–15 V DC @ 60 W is necessary.

If a power supply is necessary, we recommend the MeanWell GST60A15-P1J (15 V DC, 60 W, 4 A) power supply. However, any power supply providing sufficient power at 14–15 V DC with a plug as depicted in Fig. 1.2 is sufficient.

Note

No external power supply is provided with the TBT variants of our TDC cards.

1.1.1 Power-up sequence

The below only applies to the xTDC4-TBT and xHPTDC8-TBT card.

For a proper boot sequence, it is important to:

  • First connect the power supply.

  • Then, the EXT PWR LED will light up green (unless the supplied power is not sufficient).

  • Only now establish the the USB4 connection.

Attention

The xTDC4-TBT and xHPTDC8-TBT cards will only work with the correct power-up sequence.

In case you did not follow the above procedure and the TBT card is not recognized by your device, remove the USB4 and power supply connections, then follow the correct procedure. If afterwards the TBT card is still not recognized, a reboot of your system is necessary.

1.2 LEDs

The back panel features two LEDs:

USB-C

This LED indicates a sufficient power supply by the USB-C port if green. It is only relevant for the TimeTagger4.

EXT PWR

This LED indicates sufficient (green) or insufficient (red) power supply. If it is red, the connected power supply does not provide enough power. It is only relevant for the xTDC4 and xHPTDC8.

1.3 Inputs and connectors

For the front-panel connectors, refer to the main User Guide of the particular TDC card in your device.
