USING THE SERIAL PORT
The Multi-Station Remote Alarm is equipped with an RS-232 Serial Port. The Serial Port can be connected to
a standard PC to expand the communication features of the Alarm.
Communication between the Alarm and the PC is Asynchronous, Full Duplex. System Bank Pressure Status
along with test information can be sent to the PC. In addition, this port is used to receive commands from the
PC.
Baud Rate is 9600. No Parity bit is used.
Each time the status of a System changes the Alarm will make this information available to the Serial Port
as an 8 bit word. The data is organized such that each bit represents the status of a BANK Pressure Switch.
Table 5 shows the bit assignments.. A value of “0” in a bit indicates IN-ACTIVE or NO ALARM condition.
A “1” in a bit indicates an ACTIVE or ALARM condition.
