VeCOAX Micromod 3+ SDI Instructions
If you are installing Multiple Micromods together
Please see the MULTIPLE UNIT INSTRUCTIONS
below on this page
Single Unit Quick Installation
IF you are merging the Micromod 3+ SDI
with other coaxial TV channels,
FIRST find out a FREE CHANNEL
not used on your TV channel list
so channels will not jam each other.
Look on your TV channel list
for an UNUSED channel number.
1) THIS IS MOST IMPORTANT FOR A PERFECT SETUP
At first, connect the Micromod 3+ SDI DIRECTLY on your TV with a short piece of coaxial cable
2) No need to connect the HDMI input
3) Check on the Micromod 3+ SDI Display it shows the CORRECT Channel Name & Numbers you want.
Click here for how to set the channel
4) Rescan Your DIGITAL TV Channel List on your TV Menu to find the Micromod 3+ SDI Channel on your TV.
You will see a Test Pattern as this here below

5) If you see the Color Bars Test pattern on your TV means the Micromod 3+ SDI channel has been found and works correctly.
Click here to troubleshoot if the channel is not found
6) Disconnect the Micromod 3+ SDI from the TV
7) Connect the TV back to the regular coaxial cable
8) Move the Micromod 3+ SDI to the first Coaxial junction box splitter near the TV
Connect the Micromod 3+ SDI to the splitter so the channel signal will go to all your TVs via the splitter
Something like this picture...

9) Turn On the Micromod 3+ SDI connected to the coaxial splitter
10) Check on the same TV if you can still see the Micromod 3+ SDI color bars signal.
- IF YES, then Re-Scan all your other TVs to find the Micromod 3+ SDI channel, same as on the first TV
- IF NO, click here to troubleshoot the coaxial splitter
11) Disconnect the Micromod 3+ SDI from this splitter and connect to the next ones, one by one, repeating the same test from STEP #8
12) Connect The Micromod 3+ SDI to the Main TV Coaxial Splitter, from where you serve all TVs and check again STEP #10
14) Connect your SDI source to the Micromod 3+ SDI input and watch your SDI source as channel on all your TVs

Multiple Units Quick Installation
IF YOU USE A COAX AMPLIFIER
READ THIS FIRST:
otherwise skip this note
If you combine multiple Micromod 3+ SDI then feed an amplified splitter, and when you connect more than one unit all channels stop working β probably the signal from the combined units to your coax amplifier is too strong.
Solution-1:
On the Micromod 3+ SDI COLOR DISPLAY: MAIN MENU > CHANNEL SETUP > RF OUT LEVEL β reduce the RF OUT LEVEL of every unit to the minimum. This will reduce the MIXED signal to your amplifier so it should not have signal distortion. If needed use a Coaxial attenuator connector of 10 decibels between the mixed outputs and the amplifier input.
Solution-2:
Bypass your amplifier and go direct from the combined Micromod 3+ SDI to the TVs. The signal is already very strong and usually does not require an amplifier.
Solution-3:
Try using HIGHER FREQUENCIES, starting from 500 MHz up. This usually fixes issues with older combiners. You can use higher channels and still set your MAJOR/MINOR NUMBERS for the TV remote control to 1/2/3... Used channels on the coax (frequencies) and Channel number on the TV remote control are not related. You can always set the TV program number with MAJOR/MINOR numbers on the Micromod 3+ SDI MAIN MENU > CHANNEL SETUP > MAJOR Number & MINOR number.
IF you are merging the Micromod 3+ SDI
with other coaxial TV channels,
FIRST find out FREE CHANNELs
not used on your TV channel list
so channels will not jam each other.
Look on your TV channel list
for UNUSED channel numbers.
(A) Prepare your Micromod 3+ SDI ON Different Channels
To merge multiple Micromod 3+ SDI over the same coaxial each must be set to a different channel so they do not jam each other
Click here for how to set the Micromod 3+ SDI channels
(B) Install Your Micromod 3+ SDI one by one
1) THIS IS MOST IMPORTANT FOR A PERFECT SETUP
At first, connect each Micromod 3+ SDI DIRECTLY on one TV with a short piece of coaxial cable
2) No need to connect the SDI input
3) Check on the Micromod 3+ SDI Display it shows the CORRECT Channel Name & Numbers you want.
Click here for how to set the Micromod 3+ SDI channel
4) Rescan Your DIGITAL TV Channel List on your TV Menu to find the Micromod 3+ SDI Channel on your TV.
You will see a Test Pattern as this here below

5) If you see the Color Bars Test pattern on your TV means the Micromod 3+ SDI channel has been found and works correctly.

12) Connect The Micromod 3+ SDI to the Main TV Coaxial Splitter, from where you serve all TVs and check again STEP #10
14) Connect your SDI source to the Micromod 3+ SDI input and watch your SDI source as channel on all your TVs
Click here to troubleshoot HDMI video sources
15) Leave this Micromod 3+ SDI connected to your coaxial cables and proceed to the next Micromod 3+ SDI
Repeat from step 1 for each Micromod 3+ SDI, one by one, so if there is an issue you'll be able to troubleshoot that easily
16) When all the Micromod 3+ SDI are connected, all your TVs will be able to select and display any of the Micromod 3+ SDI channels
