A-Port: Connection for Satellite dish
B-Port: Connection for Terrestrial antenna, UHF and FM
C-Port: Connection for a modulated signal (10MM-MT67/68) so it can combine with A and B ports and be available on all outputs
TER Powering: The TER 14V power switch allows powering of a masthead amplifier connected to B/TER-port, if no masthead amplifier used switch to "0"
SAT Powering: All DDA/MST products produce 18VDC from A/SAT1 ports to power a satellite dish, LNB
SAT/TER Combine: When your UHF aerial is connected to B/TER port then switch is set to SEP (separate). When Satellite and Terrestrial are combined on same cable they connect to A/SAT1-TER port and switch set to COMB (combined). Regardless of this setting SAT/TER/BACK-feed are combined on output
SAT1: Used on the MST range and designed to connect to the main satellite dish looking at Optus D1 Horizontal for SKY and FreeView satellite
SAT2: Used to connect to a second satellite, this port produces 13VDC to select Vertical on the satellite. If the 13MM-KF15 LNB is used then Vertical and Horizontal can be received at the same time.
Outputs: The amount of outlets that can be connected to switch
Wall Friendly: Best used on a wall with inputs on left and outputs down the bottom
Hub Friendly: The 30MM-MST316 and 10MM-MST308 are designed to mount within a hub with all ins/outs on top for ease of cable management. The DDA-4-port units are small enough to still be mounted in a hub
Rack Friendly: Designed specifically to mount in a 19" communications rack. It occupies 1RU and has adjustable mounting frames so depth can be adjusted.
Powering: All DDA/MST products come complete with 1AMP 18VDC regulated power supply. All units can be powered locally or powered remotely over the coax from any of the outlets connected to any of the outputs.
All DDA/MST products come complete with a power injector, except the DDA14C, for this purpose.
