2015590-001
Peripheral Devices: Model 115-Compatible Communications Protocols
NOTE:
Refer to “Requested Data Format” later in this document for information
about the response data format. The format is the same for both the 115
Update mode and the 115 Transmit/Receive mode.
115 Transmit/Receive Mode
Once a valid request for data is received, the 120 Series Monitor will send only the
information that is requested. The selection of this information is done by sending a
request stream to the 120 Series Monitor. After processing the request, the 120
Series Monitor will then send only the
selected parameters to the external computer.
The information selected by the external computer will be transmitted following the
same criteria described for the 115 Update Mode. The requested parameters may be
changed at any time by the host computer by sending a new request sequence.
NOTE:
Refer to “Requested Data Format” later in this document for information
about the response data format. The format is the same for both the 115
Update mode and the 115 Transmit/Receive mode.
Requested Data Format
The format of the data requested by the external computer from the monitor is
shown in Figure 11-2 .
NOTE:
This applies to 115 Transmit/Receive mode only.
The definitions of the bytes are as follows:
Monitor Type
This field contains a 1-byte ASCII value indicating the type of monitor from which
information is being requested. The 120 Series Monitor is set to a fixed value of 9
(39H).
Data Field
This field of 1 to 8 bytes indicates which parameters the external computer wishes to
receive. The values for the bytes are given in
Table 11-2 .
End of Text
This 1-byte field contains the value 03H. If this byte is sent immediately following
the Monitor ID, then the 120 Series Monitor will cancel transmission of all data.
