Front Panel Indicators and Switches
The front panel LED indicators associated with each sub-channel identify the active
port. A green POWER ON LED indicates when AC voltage is applied. Two adjacent
green LED indicators illuminate in union with individual port activity and identify
Transmit Data (TXD) and Receive Data (RXD) activity.
Positive latching type switches are provided for each DTE port. These switches allow
you to isolate or remove a streaming terminal. The switch is GREEN when the
channel is active. To disable a sub-channel, push in the switch and it will click to the
out position, and turn BLACK.
