2.1 Installing the Board

The Ndigo250M-14 board can be installed in any PCIe slot with eight or more lanes. If the slot

electrically supports less than 8 lanes, the board will operate at lower data throughput rates.

Using a single Ndigo250M, no further connections need to be made. For applications that

require more than four ADC channels, several Ndigo boards can be operated in sync. Any

board of the Ndigo product line can be synced to other Ndigo boards, allowing, for instance, for

a combination of high speed ADCs (Ndigo5G) and slower high resolution ADCs (Ndigo250M-14)

or the upcoming Ndigo TDC.

The signals used for board synchronization and inter-board triggering are transferred on a

bus between the boards. Join all C2 connectors (see Figure 2.3 on page 5) on the boards using

a ribbon cable. Both ends of the bus need to be terminated properly. If using a Ndigo Crate,

connectors providing the termination are located on the crate mainboard next to the PCIe slots

to the extreme left and right. For more details, please refer to the Ndigo Crate user guide. In

applications that use only a few Ndigo boards installed directly inside a PC, termination PCBs

available from cronologic can be used.

Ndigo250M’s standard device driver can be used to read out any number of boards and acquire

data. For more complex scenarios, using the cronoSync-library, which is part of cronoTools, is

recommended. The cronoSync library is provided with the Ndigo device driver. Please refer to

the cronoTools user guide for more information.
