LEDR Series I/O Guide

MDS 05-3627A01, Rev. D

Login

The login menus allows you to log in to the radio’s operating system and 
gain access to configuration and diagnostics functions permitted for 
your assigned access level.

The username menu is where you specify the user name assigned by the 
user access administrator.

The password screen is where you specify the password associated with 
your user name to gain access to the login account. A maximum of eight 
characters is allowed.

Logout

The logout menu allows you to terminate your session with the LEDR 
radio. When this screen is displayed, press 

 

to finish your session.

Modem

This menu indicates whether the receiver demodulator has detected a 
signal, acquired the carrier, and data rate, as well as achieved a Forward 
Error Correction (FEC) lock.

This screen shows the frequency offset of the LEDR radio as measured 
in Hertz. 

This menu shows how many bytes have been corrected by the radio’s 
FEC capability.

This menu shows how many frames (blocks) could not be corrected by 
the radio’s FEC capability. 

This menu shows the current bit error rate (BER) of the LEDR radio.
