  • Page 6 UHP Software 3.0 User Manual USB (Universal Serial Bus) is a specification to establish communication between devices and a host controller (usually personal computers). VLAN A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location.

  • Page 7: Hardware Overview And Functions

    Power connector (DC IN) UHP-1000 router is powered with 24 VDC. AC Power supply adaptor is supplied with the set. The router can be powered from a DC power source (batteries, DC-DC converter), but the specific power supply mode should be agreed upon with the Manufacturer.
  • Page 8 There are double-frequency (wideband) converters containing two LOs with different frequencies. These converters are switched over using frequency 22 KHz. UHP-1000 routers do not support 22 KHz control signals and cannot switch LO in such converters. If converter switches the LO using voltage of 13/18 V, the router will be capable of switching LO frequency.
  • Page 9 UHP Software 3.0 User Manual Warning: Any operations with TX IF cable should be performed with 24 V supply voltage turned off. Otherwise, self- induction across a long cable can damage the transmitter and/or UHP. TX out output can feature 24 VDC with a high short-circuit current.

    UHP Software 3.0 User Manual Transmission of such packets via a satellite is extremely inefficient with respect to bandwidth usage, hence use is made of compression of protocols headers based on the fact that only few fields change from placket to packet, and furthermore this change can often be predicted.

  • Page 41: Multicast

    UHP routers support IGMP version 1-3, as well as static routing of multicast traffic. Static routing of multicast traffic is implemented in UHP-1000 routers as follows: To collect Multicast traffic from LAN to specified address you have to assign a map for this traffic on the modulator. The router will itself understand that the address (network) belongs to the Multicast range and will tune LAN to receive it.
