SA-USB Interface Card
Installation Sheet
Description
The SA-USB Interface Card provides a USB connection to a supported
printer or a connection to a PC. The card can be used for connecting a
printer to the control panel to print system events. The card can also
be used for PC communications, including the configuration utility (CU)
and Firmware update utility (FUU).
The default printer baud rate is 9600.
SA-USB connectors and LEDs
Refer to Figure 1 and Table 1 for a description of the SA-USB
components.

Installation
Install and wire this device in accordance with applicable national and
local codes, ordinances, and regulations.
Caution: Equipment damage hazard. This product is sensitive to
electrostatic discharge (ESD). To avoid damage, follow accepted ESD
handling procedures.
Note: The SA-USB is installed in the same location as the SA-232,
therefore the SA-232 card must be removed prior to installing the
SA-USB card.
To install the SA-USB:
1. Power down the panel and disconnect the batteries.
2. If installed, remove the SA-232 card from the panel. Refer to SA-
232 RS-232 Interface Card Installation Sheet, P/N 3101095 for
details.
3. Locate the SA-USB card location on the plastic assembly behind
the main circuit board and connector J3 on the main circuit board
(at the top-left of the main board).
4. Attach the SA-USB to the plastic assembly using two #6 plastite
screws as shown in Figure 2.
5. Connect one end of the ribbon cable (P/N 7140187) to connector
J1 on the SA-USB card and the other end to connector J3 on the
main circuit board as shown in Figure 2.
6. Connect the applicable USB cable to the SA-USB. See “Wiring.”
