Foundation Processor RS-232 Feedback

OVERVIEW
The Foundation Processor is equipped with a system that can report back its operational status via the RS-232 port. The
system reports it's operational status by transmitting a block of status data. The block is configured as 18, 8 bit words. The
first and last word always contains hexadecimal code 55 to facilitate message framing and synchronization. When the data
block is sent through an RS-232 port, each 8 bit word transmitted will also have 1 stop bit associated with it.
The Status can be activated in 2 ways. The first way is to ask for status to be sent by sending the RS-232 command "STAZ".
The second way is to enable auto status by sending the RS-232 command "ASTEZ", Once this command is sent, the S-1200/
1200U will transmit a status block whenever the status changes. Auto Status is disabled by sending the RS-232 command
"ASTDZ". Auto Status remains enabled until AC power is removed or turned off.
