DMD1050 Satellite Modem Board Theory of Operation

Connect an Ethernet cable between the unit and a computer that has web browser capability.

Access the browser and enter the default web address for the unit. Refer to Section 4 for a

complete description of the GUI Interface operation and parameters. Refer to Appendix C and

Appendix D for proper setup of the TCP-IP interface and Web Browser Setup.

3.6 M&C Default/Reset Plug Settings (JP5 & JP6)

If the user is experiencing difficulty accessing the Web Browser or the Terminal Interface, the

user can reset the interface settings by utilizing the supplied default plug CNRSHUNT. on the

JP5 and JP6 connectors. Refer to Figure 4-5. By installing the default plug onto pins 1 & 2 of

JP5 and JP6 and cycling power, the unit communication parameters will be reset to the following

settings:

� TCP-IP BOOT MODE will be set to IP TEST. (Refer to TCP-IP Setup Appendix)

� Remote Control Mode will be set to Terminal

� Terminal port will be set to RS232

� Web Browser Names and Passwords are Reset: (Refer to Web Browser Setup Guide,

Appendix D)

Once default settings have been activated, remove Jumpers.

3.7 Ethernet Data Interface – (J11)

If the Ethernet Data Interface is selected, then the Tx Clock Source will default to SCTE and the

Clock Polarity will default to Normal. The Ethernet Bridge Interface makes connecting LAN's via

satellite easy to do. Simply select Ethernet as your terrestrial interface and plug your LAN into

any of the two RJ-45 connectors on the unit. With its multi-port interface, automatic Learning

and Aging, Auto-Crossover, Auto-Polarity, Auto-Negotiation and embedded Quality of Service,

the Enhanced Ethernet Interface offers true Plug-n-Play connectivity.

The DMD1050 Ethernet Interface maintains backward compatible with the

DMD20/20LBST/DMD50/DMD2050 and the OM20. It Allows for all higher level protocols like

DHCP, UDP, TCP, HTTP, and FTP, etc. to pass transparently. And with it’s line speed learning

capability, traffic is forwarded immediately to the appropriate ports without any unnecessary

startup delay.

For users who desire more control over their traffic, the Ethernet interface provides additional

QOS controls and new features such as port based priorities, strict priority queuing, and the

ability to operate in a FIFO like mode.

When it comes to performance, the full duplex capability of the standard 10/100 interface allows

it to pass up to 20 Mbps in each direction over the satellite.

The DMD1050 supports Radyne HDLC and Comtech HDLC modes,

offering compatibility with the SLM5650A Bridge Interface.
