5. To obtain maximum protection from static, connect the CHASSIS terminal to earth ground.
6. For connections to DB37 connectors:
• P1 connects to an analog DBK card or module’s P1 connector via a CA-37 cable.
• P2 connects to a Digital DBK card or module’s P2 connector via a CA-37 cable.
• P3 connects to a Pulse/Frequency DBK card or module’s P3 connector via a CA-37
cable.
7. In regard to Screw-Terminal Block Connections:
• When tightening terminal block screws, tighten them snug, but do not over-tighten.
• The DBK206 includes 12 terminal blocks. Each block contains 10 screw-terminal
connectors.
• The DBK206 silkscreen provides labels for each terminal block (TB1 through
TB12) and for each of the block’s associated screw-terminals.
• TB9, TB10, TB11, and TB12 are used for ANALOG IN and provide a connection
option to the P1 (DB37) connector.
• TB5, TB6, TB7, and TB8 are used for DIGITAL I/O and provide a connection
option to the P2 (DB37) connector.
• TB1, TB2, TB3, and TB4 are used for Pulse/Frequency/Digital I/O and provide a
connection to the P3 (DB37) connector.
• The following pages correlate the DBK206 terminal block connectors with the
associated pins of the P1, P2, and P3 DB37 connectors. Note that the
System Connections and Pinouts chapter contains additional pin-outs, and includes
references to the 100-pin P4 connector.
