Analog Inputs Setup
The optional analog-to-digital converter inputs are ordered either through Option-12 on the base board or
Option-2 on the axes expansion board. Each option provides two 12-bit analog inputs with a ±10 VDC
range. The M-variables associated with these inputs provided a range of values b2048 and –
2048 for the respective ±10 VDC input range. The following is the software procedure to setup and read
these ports.
Base Board 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:$0711,12,12,S
; ADCIN_2 on JMACH1 connector pin 46
ACC-1P Analog Inputs
I903 = 1746
; Set ADC clock frequency at 4.9152 MHz
WX:$C034, $1FFFFF
; Clock strobe set for bipolar inputs
M505->X:$0714,12,12,S
; ADCIN_1 on JMACH1 connector pin 45
M205->X:$0715,12,12,S
; ADCIN_2 on JMACH1 connector pin 46
