The following signals are located atthe connector:AIN0- 37 19 AIN0+AIN1- 36 18 AIN1+AIN2+ 35 17 AGNDAIN3+ 34 16 AIN2-AIN4+ 33 15 AIN3-AIN5+ 32 14 AIN4-CJC+ 31 13 AIN5-AIN6- 30 12 AIN6+AIN7- 29 11 AIN7+AIN8- 28 10 AIN8+AIN9- 27 9 AIN9+AIN10+ 26 8 AGNDAIN11+ 25 7 AIN10-AIN12+ 24 6 AIN11-AIN13+ 23 5 AIN12-+13V 50mA 22 4 AIN13-AIN14- 21 3 AIN14+AIN15- 20 2 AIN15+1 EXT_TRIGDB-37 (female)37-pin connector:• AIN0± – AIN15± input channels, differential modeThe AI-207 measures inputs between AIn+ and AIn-as long as common mode voltage is within limits. Forsingle ended connections, AIn- should be connectedto AGND• +13V 50mA provides current• CJC+ cold junction compensation return line from DNA-STP-AI-U• AGND board analog ground, isolated from system ground• EXT_TRIG accepts an external trigger signal to the board
