OBM100 DESCRIPTION
The OBM100 is an out of band data modulator for use with
the SCT2X4 headend satellite to cable transcoder. The
purpose of the OBM100 is to provide a one way data
channel from the headend to a universe of set top boxes that
are being served by the headend. Usually program guide
and conditional access control information will be sent
through this channel.
The OBM100 provides two functions in the data management process. First of all it accepts an ASI transport stream
from the SCT2X4 data output connector. This is data that is
sent over the satellite path to the headend. The OBM100
takes this low data rate stream and without making any
changes to the data, outputs the data through an Ethernet
connection to the headend control PC.
After the headend PC constructs a complete data stream for
the set tops, derived from the satellite delivered data and
from locally generated data, the resulting stream is output
from the headend control PC back to the OBM100 on the
same Ethernet cable that is passing the satellite delivered
data in the other direction. The OMB100 accepts this incoming data and performs its second function – transmitting this
data stream to the set top boxes.
The OBM100 generates a QPSK modulated signal, modulated by the data stream from the headend controller, at a
data rate of approximately 3 Mbps. This signal is upconverted
to any operator selected frequency between 70 and 130 MHz
for transmission throughout the cable plant.

Setup and Programming / Software Flow Chart
GENERAL
Programming and viewing of the various setup and operating
parameters are accomplished using the front panel back lit,
two line, sixteen character wide LCD along with the LEFT,
RIGHT, UP, DOWN and ENTER buttons. Generally, the name
of the parameter is on the top line of the display and the
setting value is on the bottom line. For some parameters,
both the parameter name and value are on the bottom line.
To observe a certain parameter setting without intending to
change its value, just use the LEFT and RIGHT arrow
buttons to navigate through the menus shown in the software
flow chart below. Generally, the current setting for each
parameter is shown on the bottom line of the display. Note
that depending upon certain settings, some screens are not
needed and will be skipped.
To make a change in the displayed parameter and its setting
and if this is the initial setup, you will want to enter the ‘adjust’
mode. To do this, press the ENTER button that is located in
the center of the four arrow buttons and hold in for several
seconds until a flashing “^” appears in the upper right hand
corner of the display. After you are in the adjust mode, use
the LEFT and RIGHT arrow buttons to navigate among
screens and use the UP and DOWN arrows to change the
parameter setting.
When certain numerical values are to be adjusted, one or
more asterisks ( ) will appear above the digits to be ad* and DOWN keys to change the value
justed. Use the UP
of the digit, and the LEFT or RIGHT keys to move to another
digit. Note that the astrisk(s) will not appear when scrolling
through adjustable parameters using the LEFT arrow key
unless it has already been activated using the RIGHT arrow
key.
When ENTER is pressed, the new settings will be loaded
and stored and the unit will exit the ‘adjust’ mode. You may
wish to not press ENTER until you have gone through all
screens and settings and then press ENTER to save and
load all changes in one step, OR you can store just one or
several parameters at a time and reenter adjust mode to set
the next. Either method is acceptable.
The OBM100 has displays that show the number of frames
per second that are input from the ASI inputs and are being
sent to the RF output. Each frame that comes from the ASI
inputs contains seven packets of 188 bytes each (1316
bytes). If a connection to the headend (as defined by the
destination address) has not been established through an
ARP reply, then the characters that display the number of
frames per second for the ASI input is replaced with a "NC"
display.
The frames being sent to the RF output contain between one
and seven packets of 188 bytes, depending upon what is
being sent to the OBM100 from the headend controller. The
headend controller will need to send frames with seven
packets in each frame to allow the unit to function properly
when high data rates are being sent through the RF output.

SETTINGS
Frequency: Set the output frequency of the OBM100 as
required by the system map design. The frequency range is
from 70 to 130 MHz, adjustable in .05 MHz steps.
Output: Set the desired RF output signal level. The available range is from 30.0 to 52 dBmV in .5 dBmV steps. The
output accuracy is ± 1 dB.
OUTPUT MODE: For normal operation, select NORMAL.
For system level set up, choose CW to provide a CW carrier
at the center frequency of the output channel for use in
leveling a system when a QAM power meter is not available.
In the CW mode, the CW carrier can be measured on a
spectrum analyzer without a need to apply a bandwidth
correction or it can be measured with an analog meter tuned
to channel center. The CW power measured will equal the
channel QAM power when the modulator is returned to
normal output mode. Usually QAM signals are set 5 dB
below analog NTSC channels when balancing a system.
The PRBS menu entry is used for testing purposes only and
should normally not be selected by the user.
Symbol Rate: This setting allows selection of the output
symbol rate. Set as required by the set top boxes. The
choices are .772, 1.024, and 1.544 MHz.
Setup and Programming (cont) / Additional Information
Dest MAC: The MAC (Media Access Control) number for the
PC based Headend Controller is displayed. This number will
automatically be set once the Headend Controller has
returned an ARP reply to the OBM 100.
Dest addr: Set the IP address of the Headend Controller
here. If the Controller uses a Windows based system,
typing in “ipconfig” from the Controller command window
should reveal this address.
Dest Port: This menu entry is used to enter the desired port
address of the Headend Controller. The address range is
from 00000 to 65535.
DHCP enable: This menu entry allows DHCP (Dynamic Host
Configuration Protocol) to be enabled (ON) or disabled
(OFF). When enabled, and if the Headend Controller is
DHCP capable, the OBM100 IP address, Gateway address
ADDITIONAL INFORMATION
The OBM100 display showing the version number can also
display additional unit status and error conditions. A “c” will
appear to the right of the version number if the Headend
Controller has returned an ARP reply to the OBM100
indicating a connection being made to the OBM100. If this
“c” does not appear, the OBM100 will not send UDP packets
out the Ethernet connector. In the upper right hand corner of
the display and “E” will be displayed when an overrun error is
detected, a “P” will be displayed when an Ethernet UDP
message pacing violation is detected, an “R” will be displayed when an Ethernet receive error is detected or a “T”
will be displayed when an Ethernet transmit error is detected.
NOTE: Ethernet UDP frames sent from the Headend
Controller to the OBM100 must be paced at a consistent rate
when sending near the maximum rate for the selected
Symbol Rate to avoid dropped packets.

and Subnet mask address will be set automatically. In this
event, the next menu step will be back to the “Freq” screen in
adjust mode, or the “MAC” screen in normal mode.
IP addr: This menu entry allows the user to set the OBM100
IP address if DHCP enable is turned off. This screen will not
appear of DHCP enable is turned on.
GATEWAY addr: This screen will only appear if DHCP
enable is turned off. It allows the user to set the OBM100
gateway address. If DHCP is enabled, this address is set
automatically by the Headend Controller.
SUBNET mask: This screen will be visible only of DHCP
enable is turned off. It allows the user to set the subnet
mask for the OBM100. If DHCP enable is turned on, this
parameter is set automatically by the Headend Controller.
To update the OBM100 Application & FPGA by loading
through the Ethernet:
1) Create a folder with a name of the OBM100 current
version number and copy to this folder the latest
“OBM100.srec” and “OBM100.rpd” files.
2) Plug in the Ethernet to have the DHCP get an IP Address
or manually enter an IP Address.
3) Press and hold the left, up and store buttons on the front
panel until “Load Memory” message appears.
4) With a web browser (Internet Explorer), select the IP
address from step 2 and enter.
5) For Application press “Browse” and select file
“OBM100.srec”.
6) For FPGA press “Browse” and select file “OBM100.rpd”.
7) Press “Send”. OBM100 should display “Loading”. After
about 1 minute the display should show “Successful Load”
for about 5 seconds followed by the “OBM100” display.

Many of the products that are sent to us for repair are in
perfect working order when we receive them. For these
units, there is a standard checkout fee that you will be
charged. Please perform whatever steps are applicable
from the installation sections of the Owner's Manual
before calling or writing—this could save unnecessary
phone charges. Please do not return the unit without
contacting R.L. DRAKE first: it is preferred to help
troubleshoot the problem over the phone (or by mail) first,
saving you both time and money.
Inside the carton, enclose a note with your name, address, daytime phone number, and a description of the
unit’s problem.
The unit must be sent to the following address:

shipping damage upon receipt.
You will need to send proof of purchase to receive
warranty service. Typically, a copy of the invoice from an
R.L. DRAKE dealer will suffice. The warranty is for the
original owner only and is not transferable.
