Analog Inputs Setup

The optional analog-to-digital converter inputs are ordered either through Option-12 on the baseboard or Option-2 on the axes expansion board. Each option provides two 12-bit analog inputs with a ±10Vdc range. The M-variables associated with these inputs provided a range of values between +2048 and –2048 for the respective ±10Vdc input range. The following is the software procedure to setup and read these ports.

Baseboard Analog Inputs

I903 = 1746	;Set ADC clock frequency at 4.9152 MHz
WX:$C014, $1FFFFF	;Clock strobe set for bipolar inputs
M105->X:$0710,12,12,S	;ADCIN_1	on JMACH1 connector pin	45
M205->X:$0711,12,12,S	;ADCIN_2	on JMACH1 connector pin	46

Acc-1P Analog Inputs

I907 = 1746	;Set ADC clock frequency at 4.9152 MHz
WX:$C034, $1FFFFF	;Clock strobe set for bipolar inputs		pin	45
M305->X:$0714,12,12,S	;ADCIN_1	on JMACH1 connector (Acc-1P)	pin	45
M405->X:$0715,12,12,S	;ADCIN_2	on JMACH1 connector (Acc-1P)	pin	46
