MDC-370 DEPOSITION CONTROLLER
Example: To instruct the controller to send the source setup parameter list the
computer would send:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(18)+Chr$(0)+Chr$(237)
20. Receive source setup (Code #19)
Instructs the controller to enter the incoming source setup parameters into
memory. A description of the source setup parameter list is given above.
21. Send sensor setup (Code #20)
Instructs the controller to send the sensor setup parameter list for all sensors. A
description of the sensor parameter list is as follows:
Parameter Name Length
(bytes)
Decimal Pt.
Position
Range Units
Number of crystals 1 * (1-8) None
Shutter Relay Type 1 * 44=Normally open,
45=Normally closed,
46=None,
47=Dual None
Control 1 * 68=Direct,
69=BCD,
70=Indiv,
71=Manual None
Drive 1 * 60=Up,
61=Down,
62=Fast,
63=Inline,
64=Sngl Step,
65=Dbl Step None
Feedback input type 1 * 8 =Individual,
9=BCD,
10=Single Home,
11=In Position,
12=No Feedback
Rotator Delay 1 * (0-99) Seconds
Total 6 bytes
There are a total of six sensors with 6 bytes per sensor for a total of 36 bytes. All
36 bytes are sent in the same message starting with sensor #1.
Example: To instruct the controller to send the sensor setup parameter list the
computer would send:
Chr$(255)+Chr$(254)+Chr$(1)+Chr$(20)+Chr$(0)+Chr$(235)
22. Receive sensor setup (Code #21)
