OM20 Universal Outdoor Modem OM20 Initial Configuration

MN-OM20– Revision 5 3–3

3.2 Initial Configuration and Setup Process

The following descriptions assume that the OM20 is installed in a suitable location with prime

AC power and supporting equipment available.

CAUTION

Before initial power up of the OM20, it is a good idea to disconnect the

transmit output from the operating ground station equipment and terminate

the port into a properly sized load. This is especially true if the current

Modulator Configuration Settings are unknown, where incorrect settings

could disrupt the existing communications traffic. New units from the

factory are normally shipped in a default configuration which includes

setting the transmit carrier off.

3.2.1 Initial Power-Up and Configuration Verification

Turn on the unit by connecting the power cable to J1 of the OM20 and plugging the power cord

into the appropriate AC Mains power source. Upon initial and subsequent power-ups, the OM20

Microprocessor will test itself and several of its components before beginning its Main

Monitor/Control Prog. Upon successful completion of the powerup, the LED’s on the front of the

unit will be Green. If a failure is detected, the Fault LED will illuminate on the web browser

interface and on the front Status LED.

3.2.2 M&C Setup (IP Configuration & RS232 Interface)

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 6 for a

complete description of the GUI Interface operation and parameters. The factory set defaults for

the Ethernet port Browser are:

IP Address Mask: 255.000.000.000

Modem IP Address: 010.000.000.001

Server IP Address: 010.001.001.001

Router IP Address: 010.000.001.001

The initial field checkout of the modem can also be accomplished from the Terminal Mode. The

Terminal Mode has the advantage of providing full screen access to all of the modem’s

parameters, but requires a separate terminal or computer running a Terminal Program such as

Hyper-terminal and connection to the applicable pins on the unit M&C connector J2. The

recommended terminal setup is as follows (These settings can be changed via the Web Browser):

Emulation Type: VT-100

Baud Rate: 19.2 K

Data Bits: 8

Parity: No Parity (Fixed)

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 219 220
