Switch 2. Fiber -- Transmit All Ones
Up - Disables the Transmit All Ones
function on the fiber interface.
Down - Transmits an “all ones” pattern on
the fiber interface when the signal detect on
the coax interface is lost.
Switch 3. Not in use
Installation
-- Continued
Set the Configuration Switches
The configuration switches are located on the side of the Device.
Use a small, flat-blade screwdriver or a similar device to set the recessed switches.
Transmit All Ones
(switches 1 & 2)
The Transmit All Ones function allows the insertion of an “all ones” pattern on the
interface when the signal detect is lost, creating an alarm condition at the device
connected to the interface.
Switch 1. Coax -- Transmit All Ones
Up - Disables the Transmit All Ones
function on the coax interface.
Down - Transmits an “all ones” pattern on
the coax interface when the signal detect
on the fiber interface is lost.

Troubleshooting
If the Device fails, isolate and correct the failure by determining the answers to the
following questions and then taking the indicated action:
1.
Is the PWR
(Power)
LED illuminated?
NO
•
Is the power adapter the proper type of voltage and cycle frequency for
the AC outlet.
•
Is the power adapter properly installed in the Device and in the outlet?
•
Does the grounded AC outlet provide power?
•
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
•
Proceed to step 2.
2.
Is the SDC
(Signal Detect / Copper)
LED illuminated?
NO
•
Check the coax copper cables for the proper connection.
•
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
•
Proceed to step 3.
3.
Is the SDF
(Signal Detect / Fiber)
LED illuminated?
NO
•
Check the fiber cables for proper connection.
•
Verify that the TX and RX cables on the local Device are connected to
the RX and TX ports, respectively, on the remote Device.
•
Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
•
Proceed to step 4.
