Appendix A: 24/7 Data Acquisition Wildcard Pin-outs

Pin-outs of the two connectors on the 24/7 Data Acquisition Wildcard are presented below. To locate the connectors on the board, consult the white silk-screened labels located near each connector. Pin 1 and pin 24 are identified on each side and on each connector.

Several signals on the Wildcard Bus have compound names to suggest multiple functions. For example, SEL0/XMIT+ is a signal that can be used as a Wildcard select line or the RS485 positive transmit line. The underlined signals are used by the 24/7 Data Acquisition Wildcard while the signals with an asterisk are not.

You will generally not need to concern yourself with the Wildcard Bus signals. You will need to connect your input signals to the Field Header. Signals FIELD0 through FIELD7 provide the four fully differential or seven pseudo-differential inputs. DIN-1, DIN-2 and DIN-3 are the three digital inputs.
