Configure a Push-on/Push-off Function Key
Each of the OIT’s function keys can be configured to send two ASCII strings to the host
controller; each a maximum of 40 characters. One ASCII string is sent to the host
controller whenever the function key simulates an “on” state, the other whenever the
function key simulates an “off” state. The predefined ASCII strings can contain any
ASCII character from 0 to 255.
This step walks you through the configuration of Function Key 1 as a push-on/push-off
function key that sends the predefined ASCII string “on
CR LF
” when simulating an “on”
state, and the predefined ASCII string “off
CR LF
” when simulating an “off” state. The
predefined ASCII strings are sent to the host controller and to the OIT’s display.
