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 dis-

played 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.
