Special String Characters:
Within the strings there are nine ‘special characters’ which can be used. They are defined as follows:
END-o-STRING: (00): This special character tells the FSK/RTU that it has reached the end of the cur-
rent string it is sending.
LaserSearch: (01): Not used by the FSK/RTU.
PB: (02): Not used by the FSK/RTU.
BLUE: (03): Not used by the FSK/RTU.
GREEN:(04): Not used by the FSK/RTU.
STOP: (05): When found in a string, this character causes the FSK/RTU to close the STOP relay out-
put. It will then reopen at a later time as set by the TAPE DECK PULSE setting. When running a
tape deck from the FSK/RTU, this would normally be used to stop the tape deck at the end of
each show.
PLAY: (06): When found in a string, this character causes the FSK/RTU to close the PLAY relay out-
put. It will then reopen at a later time as set by the TAPE DECK PULSE setting. When running a
tape deck from the FSK/RTU, this would normally be used to start the tape deck at the begin-
ning of each show.
REWIND: (07): When found in a string, this character causes the FSK/RTU to close the REWIND relay
output. It will then reopen at a later time as set by the TAPE DECK PULSE setting. When running
a tape deck from the FSK/RTU, this would normally be used to rewind the tape deck at the end
of the last show on the tape.
DON’T CARE: (80): This character is used when you need to get a character returned from the se-
rial port, but just don’t give a damn what it is that you receive. The FSK/RTU will simply wait until
it gets any character through the serial port. This is the only one of the ‘special characters’
which is used when receiving characters from the serial port.
