could cause damage and invalidate the manufacturer’s warranty.
DO NOT connect the power cord to the device if the power cord or unit is damaged.
DO NOT cut the power cord.
DO NOT plug the power cord into an AC outlet until all cables and connections to the device have
been properly connected.
The device should be installed in an environment consistent with its operating temperature
specifications. Placement next to heating devices and ducts is to be avoided as doing so may cause
damage. The device should not be placed in areas of high humidity.
DO NOT cover any of the device’s ventilation openings.
If the device has been in a cold environment allow it to warm to room temperature for at least 2 hours
before connecting to an AC outlet.
IMPORTANT
ALWAYS remove any network/ethernet connection from the HD Encoder after configuring it to

Use high quality cables and connectors and insure all connections are tight
Test the coaxial cable RF output at the TV to insure the levels are well within the TV input range
Use Google Chrome, Microsoft Edge, or Mozilla Firefox as the web browser when configuring the
HD Encoder. Google Chrome is preferred.
During the web browser Admin Reboot process, use a new Google Chrome “Incognito Window” to
eliminate caching-related confusion and issues.
The factory Default is for J.83B RF output. If ATSC output is desired (example: for LATAM
installation) then the RF Setup Menu > Channel Type must be changed to ATSC, etc.

3.2.1 VCN RELATED NOTES:
VCN is the Channel number to be shown by the TV. The VCN Modes which will be available depend on
whether the output is selected as J.83B or as ATSC.
VCN Mode: Auto (two-part) - VCN will be set based on the Channel output selected in “RF Output
Menu: RF”.
Example: Output Channel set to 2. VCN for device will be set at 2.1
This is automatically set by the CH output set in the RF Setup section.
VCN Mode (Manual two-part) - VCN Manual 2-part- will allow the installer to control VCN channel
regardless of the CH/freq. selected on the RF Output Setup page of the device.
Examples:
RF CH VCN Channel
57 55.1

Step 8: Changing Password
Step 9: Hardware Installation and Connections
It is highly recommended that the highest quality cables and connectors be used for all video and audio
source connections.
1. Ensure the video Source has output.
2. Connect the HDMI cable to the HD Encoder from the Source.
3. Connect the included AC power adapter cord to the HD Encoder’s 12VDC Power receptacle at the
rear.
4. Connect the AC adapter to an appropriately rated AC power outlet.
5. Test the RF output with a CATV meter to ensure that it is within the input range of the connected
TV’s
6. Connect to the coaxial distribution using the “F” connector at the rear of the HD Encoder. Use a
high quality 75Ω coaxial cable with compression-type “F” connectors from the HD Encoder’s RF
Output. Ensure that all connections are tight.
7. When the HD Encoder configuration is complete –disconnect the HD Encoder from the
network/Ethernet to insure its security and highest performance

Step 10: Use the TV’s AutoScan to add the new modulated channel(s) to the available
TV channels
1. Make sure the correct input type is selected from the TV menu: J.83B requires the TV to be set to
“Cable”. ATSC requires the TV to be set to “Antenna” or “Air”.
2. Perform a full channel scan from the TV menu to detect all HD Encoders
4. Frequently Asked Questions (FAQ)/Troubleshooting
Most issues can be resolved by insuring the cabling is correctly and tightly connected and that the correct
parameter settings are selected in the HD Encoder and the TVs.
No Display on TV
HD Encoder or TV not setup
completely or not correctly
1. Ensure the source and the HD
Encoder are powered on
2. Ensure that there is output
from the video source (direct
connect the source with a
HDMI to a TV)
3. Ensure that there is output
from the HD Encoder –
output bit rate should be
shown on LCD
4. Ensure that the correct HD
Encoder output is selected in
RF OUTPUT SETUP, i.e.
J.83B or ATSC.
5. Ensure that the TV is set on
the correct input type: J.83B
QAM requires “CABLE”.
ATSC requires “ANTENNA”
or “AIR”.
6. Ensure that the RF level at the
coax cable is within the TV
input range
7. Ensure that the TV has
performed the full Channel
scan to detect and setup the
new HD Encoder channels.
8. Ensure the TV has been tuned
to the correct channel
detected from HD Encoder

accept unencrypted HDMI
input, i.e. user generated
video files which do not have
restricted content with HDCP
protection
No Display/Error Message on
TV with DVD/ Blu-Ray Player
Occasionally “No Input”
message will appear on TV. HD
Encoder output will stop output
if no Player input is available
1. See note above about HDCP
content restrictions
2. Player output will stop when
it is overly slow to read data
(old/dirty player)
3. Make sure the DVD/Blu-Ray
media is clean, no scratches,
no fingerprints, etc
Noise on TV
Occasionally compression
artifacts appear
1. Ensure that the source is
without noise and
compression artifacts
2. Ensure that the RF input
levels to the TV are within
range
Rebooting
Occasionally HD Encoder
reboots
1. Ensure that the HD encoder is
disconnected from the
ethernet cable to insure it is
secure from the internet,
hackers, viruses, traffic, etc
