INTRODUCTION The BNC series of signal connection boxes have been designed as universal interfaces for the DAS family of analog I/O boards. The BNC-08DI accepts up to 8 differential pairs of analog inputs while the BNC-16SE and the BNC-16DI can accept up to 64 single ended or 32 differential analog inputs. For user convenience, a variety of I/O signals from the DAS board are brought out to a 37 pin D connector at the front of the enclosure.
BNC-08DI The BNC-08DI incorporates 16 front panel mounted BNC connectors providing up to 8 differential analog inputs to the CIO-DAS family of data acquisition boards. B1-B16 The 16 front panel mounted BNC connectors B1-B16, are routed through the enclosure to the rear panel-mounted 37 D connector P2.
EXTERNAL TRIGGER The EXTERNAL TRIGGER BNC connectors B17 and B18 are provided for applications that require external digital triggering of the data acquisition board. These connectors could also be used in applications requiring synchronization to the digital trigger signal. The digital trigger signal is available on connectors P1-P4 as illustrated in the following diagram.
BNC-16DI The BNC-16DI incorporates 16 front panel mounted BNC’s allowing connection of up to 8 differential analog inputs to the CIO-DAS and PCI family of data acquisition boards. The BNC-16DI can accommodate boards with either 37 or 50 pin I/O connectors; with connector P2 used to interface to data acquisition boards utilizing a 37 pin, D type I/O connector, while connectors P3, P4 and P5 are used to interface to data acquisition boards utilizing a 100 pin I/O connector.
. . P1 The front panel mounted DB37 connector P1 provides a variety of I/O signals, not including the 16 analog input signals from BNC’s B1-B16. Please refer to the P1 CONNECTOR MAP section for a detailed explanation of P1’s connection scheme and signal availability.
EXTERNAL TRIGGER The EXTERNAL TRIGGER BNC connectors B17 and B18 are provided for applications that require external digital triggering of the data acquisition board. These connectors could also be used in applications requiring synchronization to the digital trigger signal. The digital trigger signal is available on connectors P1-P4 as illustrated in the following diagram.
Headers P6 and P7 are factory set to the “1-2” position, pre-configuring B15 and B16 as analog input BNC’s. For those applications which require D/A outputs along with B15 and B16 to be used in the analog input mode; the user can leave B15 and B16 in the analog input mode and access the D/A outputs at connector P1. The following diagram illustrates the connection scheme used to route the D/A output signals from P2-P4 to B15, B16 and P1.
BNC-16SE The BNC-16SE incorporates 16 front panel mounted BNC’s allowing connection of up to 16 single-ended analog inputs to the CIO-DAS and PCI family of data acquisition boards. The BNC-16SE can accommodate boards with either 37 or 50 pin I/O connectors; with connector P2 used to interface to data acquisition boards utilizing a 37 pin D type I/O connector, while connectors P3, P4 and P5 are used to interface to data acquisition boards utilizing a 100 pin I/O connector.

The following diagram illustrates the connection scheme used to route the D/A output signals to from P2-P4 to B15, B16 and P1.
P1 CONNECTOR MAP Connector P1 provides the user with a variety of I/O signals, not including the 16 analog input signals from B1-B16. The following diagram illustrates the connection scheme used to route these signals among connectors P2, P3 and P4 to connector P1. These signals are labeled “PASS” signals (except for the trigger and D/A options as shown) and the user should consult their DAS manual’s I/O connector pin assignment section to verify the actual signals available at the P1 connector.
