MDC-260 DEPOSITION CONTROLLER
COMPUTER INTERFACE 11-11
11.8 INSTRUCTION DESCRIPTIONS
The following section describes all of the valid instructions and shows examples
of how they are used. Each example is show in decimal [Dec] and hexadecimal
[Hex]. Each successful command will immediately prompt the MDC-260 to send
a transmission receipt, as described previously. If the message asked the MDC-
260 to transmit data back to the host computer, an example of that data is also
shown. Assumptions about the status of the MDC-260’s parameter data are
explicitly stated.
In parameter data tables, entries in bold represent the factory default values. In
the instruction examples, entries in bold represent variable fields that may change
depending on the data transmitted. If a checksum is provided in the example, it
will need to be re-calculated if any of the variable data changes.
Note: All examples assume the target controller’s USB Interface Address is 01.
