Once the Model 1094ARC is properly configured and installed, it
should operate transparently. These sections describes functions of
the LED status indicators, and the use of the built-in loopback test
modes.
5.1 LED STATUS INDICATORS
The Model 1094ARC features twelve front panel LEDs that moni-
tor power, the DTE signals, network connection and test modes.
Figure 11 (below) shows the front panel location of each LED.
Following Figure 10 is a description of each LEDs function.
TD & RD
glows yellow to indicate an idle condition of Binary
“1” data on the respective terminal interface
signals. Green indicates Binary “0” data.
CTS
consists of 2 LEDs, 1 yellow, 1 green. CTS glows
green to indicate that the Clear to Send signal
from the modem is active. Yellow indicates inac-
tive CTS.
CD
consists of 2 LEDs, 1 yellow, 1 green. CD glows
yellow if no carrier signal is being received from
the remote modem. Green indicates that the
remote modem’s carrier is being received.
DTR
glows green to indicate that the Data Terminal
Ready signal from the terminal is active.
Notice!
Any modular twisted pair cable connected to
the Model 1094ARC must be shielded cable, and the outer
shield must be properly terminated to a shielded modular
plug on both ends of the cable.
