F1, LCD Display – This display presents the selected menu
screen and the parameter settings. The backlight in the
display is on when power is applied.
When not in adjust mode the firmware version number is
displayed on the top line, and the unit’s IP address, if
programmed, is displayed on the bottom line. If DHCP has
been enabled but the unit has not been connected to an
appropriate DHCP enabled PC based controller,
“DHCP............” will be displayed instead of an IP address.
Pressing the UP or DOWN buttons cycles the display
through the firmware version screen, the data rate screens,
and the MAC number screen.
F2,
Left and
Right Buttons – Use the LEFT and
RIGHT arrow buttons to navigate from screen to screen to
view a parameter setting. These buttons are operational in
the normal mode or the adjust mode. Using only these
buttons will not change any parameter setting.
F3,
Up and
Down Buttons – Use the up and down
arrow buttons to change the value of a viewed parameter
setting. The unit must be in the adjust mode in order for
these buttons to become active for changing a parameter
setting.
F4, ENTER Button - Use the ENTER button to enter the
adjust mode or to save and load a new setting or settings
after adjustment. Hold for approximately 2 seconds until a
flashing “^” appears in the upper right hand corner of the
display to enter the adjust mode. After entering the adjust
mode, momentarily pressing the ENTER button again will
load and save any settings that may have been changed
using the UP and DOWN buttons, and will exit the adjust
mode. Note that the adjust mode cannot be entered from the
firmware version number or MAC number screens.

R1, RF OUTPUT – This type "F" connector is the high level
(+52 dBmV), 70 to 129.95 MHz, output from the OBM100
upconverter section.
R2, ASI INPUTS - These four BNC type connectors accept
ASI transport streams from the data output connectors of up
to four SCT2x4 Transcoders.
R3, ETHERNET - This Ethernet connector provides two way
communication between the OBM100 and a PC based
headend controller. It is recommended that the headend
controller has a separate Ethernet card so that a crossover
cable can be used to connect directly to the OBM100.
If a network connection is used, the OBM100 must be
connected to a firewall device that restricts the Ethernet
communications to be only Ethernet frames to and from the
headend controller.
R4, RS232 - This DB9 serial connector is for factory use only.
R5, AC Line Cord – For connection to the nominal
120 VAC power source. This unit is designed for use in
countries with 120 VAC power standards with a power line
frequency of 60 Hz. The maximum power consumption is 10
watts.
