SystemQ MOD300 Digital HD Modulator
Overview
The MOD300 converts an HDMI output from a DVR (or other equipment such as a
Satellite box) into a digital RF signal or “Digital TV channel”. It can then
be viewed on a DVB-T equipped TV.
Note:
The MOD300 has to process and digitize the HDMI input and this creates a
delay or “latency” in its output, this is typically in the region of 1
second.
- Remove all the power to the modulator when connecting or removing cables.
- Connect an HDMI cable from the DVR / NVR (or other video equipment) to the HD IN of the MOD300.
- When combining the RF signal of a TV aerial and the MOD300, connect the TV aerial coax (f-connector) to the RF.IN port. If using a masthead amplifier, see the full manual.
- Connect a coax (f-connector) to the RF.OUT port direct to a TVs aerial socket or to a distributor to multiple TVs.
- Connect the 12V DC power supply to the MOD300, then re-tune the TVs.
LED Indicators
- Power = On when the power supply is connected
- HD / AV = Indicates the source which it is set (HD is on as default)
Controls
- Increase or decrease the selected parameter/menu
- Move to the next or previous digit/character
- Enter the menu system / select parameter / confirm selection
- Return to the previous menu / cancel selection
The MOD300 has been designed for use in the UK, as standard the channel appears as “SBox” and channel 800 on the TV. Settings will need to adjust if using multiple MOD300s or if the default channel is already in use or to change the channel name. For menu configuration see the full manual.
