TRIAX TDSCR 512 Way Sky Qâ„¢ Multiswitch

There was a minor design flaw in some of the 1st batch of dSCR switches…… when the termination switch was set to “ON” it also switched off the DC power on the trunk lines (input and output). If the switch is used as end of line, or stand-alone, this may be a problem. The solution is to leave the termination switch to “OFF” and fit DC block terminators to the trunk outputs.


Triax TdSCR 512 dSCR / Legacy Multiswitch
- Designed to support a wide range of new and existing multiswitch installations

5 Inputs - 12 Outputs - (16 User bands or Legacy)

- 4 cascadeable LNB inputs from 1 universal Quattro LNB
- 2 Wideband LNB inputs (Vertical, Horizontal) for a 2 satellite installation
- 1 cascadeable terrestrial trunk input
- 1 level adjuster for terrestrial signals 0 - 20dB
- 4 SCR/Legacy outputs
- 1 DC input (for switch, line and LNB powering)

- Each output can support a wide variety of satellite receivers:
~ In legacy mode, the outputs can be used as a standard multiswitch
~ In SCR mode, each output supports up to 16 User Bands with all versions of the single cable technology. This includes OLT, SCR, CSS, SKY UK, EN50494 and EN50607
- As all outputs are independent, the installation can be a mix of legacy and dSCR connections
- The terrestrial input supports any services that operate between 47 - 790MHz, which includes terrestrial TV, DAB and FM reception
- The trunk outputs allow the cascade of multiple switches to support large installations and have a 75Ω self-termination toggle switch
- Can be used as a Cascade, Standalone or Terminated Multiswitch
- The DC power can be inserted into the switch on the F connector, or at any point in the system. In cascaded systems multiple power supplies might be required
