Section 5

5.2.1 - Listen/Talk Structure

Interactions between the Model 9002 and a remote controller should follow the command structure shown below:

5.3 - Key-Push Commands

Key-push codes instruct the unit to perform as if commanded by the front panel thus allowing the remote controller

to perform all functions available under local operation. Each Key-push codes is independent and instructs the

Model 9002 to perform front panel functions, one step at at time.

Table 5.1 lists the hex codes for the front panel function keys. These keys are described in Section 4.3.

Note

Key-push codes that control a toggled function are indicated by an asterisk [*].

Care should be taken to empty these codes only when previous system status has been defined earlier in the

program lest they inadvertently switch important functions ON or OFF.
