Switches 1-4 and LEDs 1-2 mount on the front panel. The toggle power switch, SW4 is the only switch
that will have 12 volts on it. The LEDs just push through holes. Note the polarity of the LEDs, the flat side
should go to ground. You may want to use some silicon RTV or glue to help hold in the LEDs.
Use the stand offs to mount the PC board in the box. Use the six mounting holes provided on the PC
board. If you are worried about RF getting into the system, you may want to connect an additional ground wire
from one of the mounting bolts to the chassis.
Once everything is mounted and wired, apply power again to make sure everything is still working.

Menu Functions:
This section will provide an overview of each menu and an explanation of the data presented on the LCD
module.
Current Voted:
The Current Voted menu displays which site is currently selected by the voter. The LCD will show only
one of the eight numbers in its position when selected (site one is in position one, site two is in position two,
ect.). On power up, site one will be chosen for the default. The display is updated when a new site is chosen as
the current voted. A site can not be selected as the current voted site if it has been disabled by either hardware
or software.
There are no user inputs for this menu.

Current CORs:
The Current COR shows which sites have active CORs. The LCD will show all site numbers in their
position when active. The LCD will update the display in real time. That is, if the COR for site one becomes
active, the display will show site one. If the COR becomes inactive, the display will immediately (within 50
mSec.) remove site one. A site will not be shown if it has been disabled by either hardware or software. The
display is updated when any COR input has changed.
There are no user inputs for this menu.

Channel S/N:
The Channel S/N menu will display the signal to noise ratio of the selected channel. There are two modes
of displaying the S/N ratio. The first is the internal number (0 to 255) used to represent the S/N ratio of each
channel (a higher number represents a higher signal). The second is a bar graph that approximates an “S-
meter” reading according to the S/N ratio. The select switch can be used in either mode to cycle through each
site. The data switch is used to toggle between number and bar graph mode.
