The ZPR68-10 will respond to any IR command by returning data via the serial port. The
response occurs approximately one second after the last IR command is received. Data
is returned only for the zone or zones which have received an IR command. Global IR
commands will cause data to be returned for all zones. An "empty" global IR command
consisting of the GLOBAL button followed by the ADJ-OFF button will cause data to be
returned for all zones without causing anything to change.
DATA FORMAT
Data is sent as a string of ASCII characters. The first string in any group of strings, is
preceeded by a line-feed (0Ah), a carraige-return (0Dh) and a bell (07h) and each string
is followed by a line-feed (0Ah) and a carraige-return (0Dh). If more than one string is
sent, the second and subsequent strings are preceeded by a bell (07h) and each string
is followed by a line-feed (0Ah) and a carraige-return (0Dh).
Each string consists of 13 data fields. Each data field consists of one, two or three ASCII
data characters followed by a tab (09h).The order of the fields in each string is as
follows:
