5.8 Equipment Terminal Services
This capability enables factory operators to exchange messages with the host. It is particularly
useful for passing instructions to the operator.
When the host sends a terminal message to a DEK printer, an indication of a message is
displayed at the equipment console. This indication message will remain displayed until either,
the operator presses a button indicating it has been read or, the host sends a new zero length
text. When the operator presses the read complete button, an event report CEID is sent to the
host.
The operator can enter a terminal message, at the equipment console, which will then be sent to
the host.
For Operator procedures see Appendix B.
Terminal Services State Model:
The terminal services state model is implemented on the DEK printer.
State Diagram:
State Definitions:
Idle - No host text is displayed on the terminal.
Not Acknowledged - Host text is displayed and not yet acknowledged by the operator.

5.9 Error Messages
This capability provides reporting of communications link errors to the host. All of the stream 9
messages as define in SEMI standard E5 are supported. The message structures are included in
section 4.9.
5.10 Clock
The DEK printer maintains an internal, host viewable, clock that is used for event report time
stamps. In order to differentiate between near simultaneous events, the clock has a precision of
0.01 seconds. It is not guaranteed to be accurate to the same level.
Note that the host must use the set time message S2F31 to synchronise the equipment. This
message contains the TIME variable defined in the machine variables, which has a precision of
1 second when the 12 byte format is used. When the 16 byte format is used it has a precision of
0.01 of a second. The format that is in use depends on the value of variable TimeFormat.
Scenarios:
Host requests that the equipment time is set:
