MDS 05-3627A01, Rev. D LEDR Series I/O Guide 43

This menu is used to enable (key) or disable (dekey) the transmitter or

to verify that the radio is keyed and the transmitter is active. The radio

is normally keyed and transmitting whenever power is applied.

This menu displays the bandwidth setting of the radio. The bandwidth is

set at the factory and cannot be changed by the user. Refer to Table 10

on Page 23 for allowable combinations of bandwidth, data rates, and

modulation types.

This menu displays the modulation type and the aggregate link data rate.

The available modulation types are QPSK, 16 QAM, and 32 QAM. The

data rate can be changed, but is dependent on the modulation type. See

“Bandwidths, Data Rates and Modulation Types” on Page 23.

6.0 CONFIGURATION AND CONTROL

VIA THE CONSOLE PORT

6.1 Introduction

The CONSOLE Port on the front panel provides full access to configura-

tion and diagnostics information. It is the most common way to access

the LEDR radio for its initial configuration. The

CONSOLE Port is an

EIA-232 connection that provides ASCII text communications to a con-

nected terminal.

Most of the commands listed on the following pages are available

through other communication channels as well. These include Ethernet,

IP, Telnet and the rear panel Service Channel.

Refer to I/O Connector Pinout Information on Page 127 for connector

wiring details.

NOTE: It is important to use a terminal or terminal-emulator that

supports 80 characters-per-line and 25 lines-per-screen. The

display will be distorted if terminals with different line charac-

teristics are used.
