Installation - Settings
There are 3 ways you can change the settings:
Front Panel. Press the SETUP button use the Up/Down buttons to move through menus, Left/Right to
change settings, then press SELECT to store the changes at each step.
o Select a menu group (Quick, A, B, QMOD), then SELECT to view that group’s menus
o Press SETUP to move back to other menu groups
o Pressing the left and right buttons together will reboot the unit
Ethernet. Access the onboard Web pages. Helpful for remote access when system is fully integrated
with site Ethernet.
USB-Web. Access Web pages from front-panel USB port, simplest solution for full setup, requires no IP
setup or connection, connect from the front of the equipment rack
Front Panel Menus
There are four groups of menus you can choose from:
Quick Setup supplies just the few steps needed to output the source as a channel.
Program A goes deeper in to all the options for the first source
Program B does the same for the second source, if that option is enabled
Common menus set the core values for the entire channel, such as IP address, level, cable plan, and
other options
Quick Setup Menus
This series is designed for a quick setup for testing and integration.
Sets the physical channel, 2-135
Sets the RF level for the channel
29 | 25 | 21 | 17 | 13 | 9
Selects the video input for Program A
SDI 1 | SDI 2 | Video 1| Video 2
Selects the audio input for Program A (SDI group follows input)
None | SDI G1 | SDI G2 | SDI G3 | SDI G4 | Coax 1| Coax 2 | Analog 1| Analog 2
Selects the video input for Program B
None | SDI 1 | SDI 2| Video 1| Video 2
Selects the audio input for Program B (SDI group follows input)
None | SDI G1 | SDI G2 | SDI G3 | SDI G4 | Coax 1| Coax 2 | Analog 1| Analog 2
At this point, you should be able to view the QMOD channels on a test TV. Note that setting Video B input to
None will automatically put the encoder in to single-channel mode, and revert to 2-channel mode when inputs
are selected for Program A and B.
A QMOD Channel, or any QAM Channel, can include two video streams, called Programs. It’s really one stream
that contains both videos. The TV figures out which to play using the channel ID, typically something like
channel IDs 2.1 and 2.2, 3.1 and 3.2 and so on. For marketing purposes we use the popular term “2-Channel”
the general public understands, for integrators we use the more correct term “2 Programs”.
