Modulator / Modulateur MOD 103T
Introduction
The MOD103T modulator has an HDMI input with local loop through, and a COFDM output which is combined with the RF input. The HDMI input content can be supplied by a number of sources, Blu-ray player, Satellite Set top box, CCTV etc. The input signal is modulated as a COFDM output and can be distributed to a number of TV’s over an existing private coaxial network. It has an HDMI loop through, to connect to the local TV, and can also combine existing RF with the modulated output channel on RF Out 1 and RF Out 2. The modulator has adjustable level control to balance the COFDM channel with the incoming RF channels. The source Set top box can be controlled from another TV location, via the IR remote control over the coaxial cable, using an IR transmitter and a digital link. The coaxial network must be connected to the RF Out, with the 9vdc able to pass through the network, to remotely power the digital link. The MOD103T Modulator can be set up, via the front panel and LCD screen. Please see below for full instructions.

Connect more modulators
Connecting of 2 or more modulators together
Two, or more modulators can be combined together and the signal can then be distributed over the TV distribution network. There are a few parameters that have to be changed on the modulators to enable the TV’s to see all the channels.
- Each modulator must have a different output channel/frequency.
- Each modulator must have a different Local Channel Number (LCN).
- Each modulator must have a different Service ID Number.
Note: if IR control is required, use RF2 out
