8-11 Strobe Address Operation
Another method of reading the status of a unit
with either a RS232 or RS422 option is by means
of a separate strobe address and a 3 bit data
request code. The strobe address method does
not allow changes of set points. Theoretically
hundreds of units could be linked together to
transmit data from The Unit over a serial
transmit line. The units could be assigned any
code number except "00".
The 3 bit data request code would be latched in at
the positive edge of a 3 to 30 VDC strobe input
that remained high a minimum of 25
milliseconds. Requests are processed on a non-
priority basis. Normally data will begin to be
transmitted from The Unit over the RS232 or
RS422 serial transmit lines within 5 msec unless
interrupted by a keypad entry or other signal
input.
Note: No other unit should be brought on line
until data requested has been transmitted.
