Switches on the D9131A assign the address to the printer. The address determines if the printer is supervised, the printer's scope, and the area to which the printer is assigned. See Printer Parameters in the D7212G Program Entry Guide (P/N: 4998138538) for a complete description of addresses.
Table 15 shows the correct switch setting for Address 17.

11.3.2Supervision
Supervision includes proper operation of the SDI bus, proper connection of the printer cable between the printer and the D9131A, printer paper supply, printer selected
The panel sends an SDI failure report to the receiver if it fails to communicate with the printer interface, and
SERVC PRINTER displays at the command center. The report to the receiver includes the address of the troubled D9131A to indicate which printer needs service.
If an SDI device is supervised and SDI A becomes disconnected, the device may still operate normally, depending upon environmental conditions.
