Installing multiple digi-MOD’s in an installation

Please ensure each digi-MOD has different settings in the categories below if you are installing 2 or more in 

an installation.

NOTE: 

correctly.

CHANNEL NAME

 can be changed by using the Scroll “UP” key until you reach “ENCODER SETUP”.      

Select the Encoder you want to adjust (1,2,3,4), Scroll to “CHANNEL NAME”. Use the UP/DOWN scroll 

LCN

channel number (e.g. 4, 5, 6, 8) by scrolling UP/DOWN in the ENCODER SETUP, Select the Encoder you 

want to adjust (1,2,3,4),  Scroll to LCN. Once selected, press the “OK” button to lock your LCN Number.

NOTE: Repeat this process for each Input of your digi-MOD Modulator.

1.  Connect the RCA cable from the video source (eg: Cable TV, Pay TV, DVD, VCR, Camera) to the yellow 

RCA Video Input       (Video) on the rear of the RL-DM4000D Modulator.

2.  Connect the RCA cable from the audio source to the red/white Audio Inputs       (Audio  L  & R) on the 

rear of the RL-DM4000D Modulator. 

3.  Connect the RF Output       from the RL-DM4000D to the Modulator Input on the RF Distribution Module 

RL-RF380. Alternatively connect the RF Output        to an existing distribution system or directly to a 
television set.

4.  Connect the supplied 12V DC Switch Mode Power Supply to the Power Input       .
5.  Repeat steps 1 - 3 for connection of other sources to AV Inputs IN2 - IN4. 
6.  Slide the Remote Power Switch       to “ON” if connecting the Modulator to a  RL-RF380 Video Hub.
7.  Connect IR emitters RL-IR700/800 to the outputs       on the rear of the RL-DM4000D Modulator.  Place 

the other end within 25mm of the IR receiver on the AV source (depending on environmental conditions).

Safety Precautions

 

Do not

 apply power to the DVB-T Digital IR Modulator until all components have been installed and all wiring has 

been properly terminated. Failure to do so may result in damage to the product and void manufacturer’s warranty

 

Do not

Adapter from the DVB-T 

Digital IR Modulator

 

Do not

 expose any component to moisture. Doing so can create electrical hazards or render the component 

unusable. Exposure to moisture will also void the warranty on the system.

 

This modulator is powered with a voltage of 12 VDC. The power supply voltage must not exceed this, otherwise this 
modulator could suffer irreparable damage and subsequent invalidation of the warranty.

       

Note:

      - 

Do not

 replace the power supply with a voltage greater than 12 VDC.

       - 

Do not

 connect the modulator to the power if the power cord is damaged.

       - 

Do not

 plug the modulator into the mains supply until all cables have been connected correctly.

       - 

Do not

 cut the cord.

 

Avoid placing the modulator next to central heating components and in areas of high humidity.

 

Do not

 cover any modulator elements that could obstruct the ventilation slots and cause overheating.

 

If the modulator has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before 
plugging it into the mains.

 

Do not

 place digi-MOD on top or underneath a PVR Device, as this could cause overheating.
