3.13 :DISPlay subsystem
The display subsystem controls the display of the Model 2002 and is summarized in Table 3-5.
:TEXT commands
:DATA <a>
:DISPlay[:WINDow[1]]:TEXT:DATA <a> Define message for top display
:DISPlay:WINDow2:TEXT:DATA <a> Define message for bottom display
<a> = ASCII characters for message
Types: String ‘aa...a’ or “aa...a”
Indefinite Block #0aa...a
Definite Block #XYaa...a
where; Y = number of characters in message:
Up to 20 for top display
Up to 32 for bottom display
X = number of digits that make up Y (1 or 2)
:DATA? Query the defined text message
These commands define text messages for display. A message can be as long as 20 characters
for the top display, and up to 32 characters for the bottom display. A space is counted as a char-
acter. Excess message characters results in an error.
An indefinite block message must be the only command in the program message or the last com-
mand in the program message. If you include a command after an indefinite block message (on
the same line), it will be treated as part of the message and is displayed instead of executed.
PRINT #1, "output 16; :disp:text:data ' Model 2002';data?" ' Define and query
message
PRINT #1, "enter 16" ' Get response mes-
sage from 2002
:STATe <b>
:DISPlay[:WINDow[1]]:TEXT:STATe <b> Control (on/off) message; top display
:DISPlay:WINDow2:TEXT:STATe <b> Control (on/off) message; bottom display
<b> = 0 or OFF Disable text message for specified display
= 1 or ON Enable text message for specified display
:STATe? Query state of message mode for specified display
These commands enable and disable the text message modes. When enabled, a defined message
is displayed. When disabled, the message is removed from the display.
A user defined text message remains displayed only as long as the instrument is in remote. Tak-
ing the instrument out of remote (by pressing the LOCAL key or sending LOCAL 16), cancels
the message and disables the text message mode.
