10 Monitoring & Controlling a PSI
The Pocket Serial Interface (PSI) is a portable, battery-powered IQ interface. It also contains a DSPI and a
standard IQ AUX port which can be monitored and controlled by the IQ System. Its AUX port output makes it very
handy for controlling remote non-IQ devices. And the sensing capability of the AUX port input can be used to sense
an external signal. The PSI Control Block screen is shown below in Figure 10.1:

10.1 Initializing a PSI Control Block
The first step in initializing a PSI control block is to set the IQ address and Crown Bus loop number. This is normally
done automatically during a roll call. However, you can set them manually if you need to configure a system off-
line.
IQ Address & Crown Bus Loop: The IQ address number you enter must match the physical IQ address
switch setting on the PSI. The Crown Bus loop number must match the physical loop to which the PSI is wired.
On Line: The phrase “On Line” will appear in the upper right corner of the information area when a PSI is
actively connected to and in communication with the IQ System.
Model, Location & Purpose: These three text lines are available for you to include relevant notes about
the unit. Up to 15 characters can be entered on each line.
