4.6.12 CONTROL PORT ANALOG INPUTS
Spec: Each input measures 0, 5, and 10 VDC within
10%.
Procedure:
Inject 10 VDC into the odd Control Port Analog Inputs.
Inject 5 VDC into the even Control Port Analog Inputs.
Use the following commands to verify the odd analog
inputs are between $FF and $E6:
DA DT CT 81 54 0A CS; Get Control Port Analog Input 9
Return String: DA DT AK CT 81 54 0C IN9 CS
Send: DA DT CT 81 55 0A CS; Get Control Port Analog
Input 11
Return String: DA DT AK CT 81 55 0C IN11 CS
Send: DA DT CT 81 56 0A CS; Get Control Port Analog
Input 13
Return String: DA DT AK CT 81 56 0C IN13 CS
Send: DA DT CT 81 57 0A CS; Get Control Port Analog
Input 15
Return String: DA DT AK CT 81 57 0C IN15 CS
5.13.4. Use the following commands to verify the even
analog inputs are between $98 and $66:
Send: DA DT CT C1 54 0A CS; Get Control Port Analog
Input 10
Return String: DA DT AK CT C1 54 0C IN10 CS
