Figure 2.1: If several Ndigo boards are connected to work in sync , the boards must be connected

using a ribbon cable as bus for synchronization and trigger signals. At both ends of

the cable, proper termination is required.

2.2 Ndigo5G External Inputs and Connectors

2.2.1 Connectors

The inputs of the Ndigo5G are located on the PCI bracket. Figure 2.3 on page 5 shows the

location of the 4 analog inputs A to D and the two digital inputs G (GATE) and T (Trigger).

Furthermore, two board interconnection connectors can be found at the top edge of the Ndigo5G,

as displayed in Figure 2.3 on page 5. Connector C1 is used for a board-to-board connection (e. g.

to link a HPTDC8-PCI and a Ndigo5G via a Ndigo Extension board, see chapter 2.3). Connector

C2 is used as a bus interface between multiple Ndigo boards distributing clock, trigger and sync

signals. Proper termination must be placed at both ends of the bus interconnection ribbon

cable.
