连接BNC-2090和M系列板卡

硬件: Multifunction DAQ (MIO)>>Connector Blocks>>BNC-2090, Multifunction DAQ (MIO)>>M Series

问题: M系列板卡引脚是如何对应BNC-2090支架式附件？

解答: 以下的信息对于80通道M系列板卡的第二个连接端子并不适用。对于80通道设备，仅使用0号连线端子通过SHC68-68-EPM与BNC-2090连接就可以了。

	BNC-2090前面板标签	对应的M系列0号接线端	对应的M系列1号接线端
BNC	ACH<0..15>	AI<0..15>	AI<16..31>
	DAC0OUT	AO0	AO2
	DAC1OUT	AO1	AO3
	EXTREF	APFI0	APFI1
	PFI0/TRIG1	PFI0	P0.16
	USER1	User Selected	User Selected
	USER2	User Selected	User Selected
接线端子	DIO<0..7>	P0.<0..7>	P0.<8..15>
	DGND1	DGND	DGND
	USER1	User Selected	User Selected
	EXSTRB	PFI10/P2.2	P0.26
	SCANCLK*	PFI11/P2.3	P0.27
	+5 V	+5 V	+5 V
	GND	GND	GND
	PFI<1..9>	PFI<1..9>	P0.<17..25>
	DGND2	PFI15/P2.7	P0.31
	USER2	User Selected	User Selected
	FREQOUT	PFI14/P2.6	P0.30
	CTR1OUT	PFI13/P2.5	P0.29
	CTR0OUT	PFI12/P2.4	P0.28

*SCANCLK对应NI-DAQmx术语中的AI HOLD COMP。

有两个接线端的M系列板卡与两个BNC-2090对应能够访问的I/O
