User Interface
Control Panel
Figure 2-3 shows a view of the 848733907 user interface control
panel used with the J85501M-1 List 1 and List 2. This assembly
interfaces with the BUJ1 connection board via a 14 pin cable
attached to J9, and a 12 pin flex-cable (keypad) to J6. The
848733907 provides a comprehensive user interface to the
controller. It is used to view plant voltage and load, configure
thresholds and other system parameters, view active alarms and
to initiate system operations. This interface consists of a 4 line x
20 alphanumeric character LCD, a nine key keypad, and three
status LEDs. A contrast control potentiometer is located just
behind the display on the BUJ1 board.
J4 (Local Port) A standard DB9 connector (J4) is provided on the BUJ board for
local terminal access. This local port is referenced to the battery
side of the power system. Connecting non-isolated (earth
ground referenced) terminal may cause damage. Laptop
computers running on battery can typically be connected to the
local port. AC line powered terminals, as well as some AC/DC
supplies for computers and laptops are referenced to earth
ground. For these applications isolation is required between the
terminal device and the controller's local port. For cases
requiring isolation a commercially available external port
isolation device, connected through J4 (local port), is required,
or a Lineage Power BSM4 can be purchased and connected
through J5.
J5 (Option Port) A 14 pin connector (J5) provides RS-232 connection to option
boards which provide remote access. These are: optional
network interface card EBW1 Gateway or a BSM3 modem
board. It should be noted that the BSM3 modem board also
provides an isolated RS-232 port.
See Appendix A for more specific details about connecting to
these ports.
