The DW4000 DIRECWAY system communicates with a geostationary satellite in a "two-way" manner; i.e. the receive (or downstream) data and the transmit (or upstream) data signals both operate through the system's antenna, over the satellite, and via the DIRECWAY Network Operations Center. No phone line, no dial-up connection. And with the DW4000 your DIRECWAY services are always-on.
And that's not all. DW4000 system can be configured with an optional dual-LNB for receiving DIRECTV® digital satellite television service. DIRECTV receivers and service are sold separately. Now the excitement of broadband Internet AND the quality choice of digital satellite television can be received on a single satellite system....DirecDUO.
Equipment Details
The DIRECWAY DW4000 systems consist of a oval satellite antenna, matching integrated outdoor electronics, and the indoor units (see below for further descriptions).
Indoor Equipment
The indoor equipment consists of one or two USB satellite adapters:
- ITU (Indoor Transmit Unit, Model DW4000 only)
- IRU (Indoor Receive Unit, Models DW3000/4000)
The DW4000 indoor equipment package is shown in Figure 1. Include are the ITU, IRU, power supply, USB cable, and ITU-IRU interconnection cable.
The IRU is a DVB compliant satellite adapter that can be used alone, in the one-way configuration, or together with the ITU for two-way operation.
The DIRECWAY ITU is designed to be an add-on capability to a standard receive-only DIRECWAY IRU. When the ITU is installed and configured, the user will have the ability to select the satellite instead of the modem as the outbound route. When this option is selected and the ITU is available, the system is essentially "always on". This means you never have to wait for your PC to connect, or worry about ISP busy signals. And because the ITU is connected to the IRU through the ITU-IRU interconnection cable, only one USB port on your PC is required to operate the DIRECWAY indoor equipment.
Outdoor Equipment
The DIRECWAY antenna is equipped with the following:
- A single LNB to receive DIRECWAY data from the satellite (Models DW3000/4000)
- A radio unit to transmit DIRECWAY data to the satellite (Model DW4000 only).
In addition each DIRECWAY system can be optionally equipped with an additional dual- LNB to receive DIRECTV using the same antenna. This configuration is called DirecDUO. Figure 2 shows the DIRECWAY antenna configured without the DirecDUO option. The outdoor equipment is connected by two RG-6 coaxial cables to the indoor equipment.
Installation
The two-way DW4000 system, as well as the DW4000U transmit upgrade, are installed by a professional installer. (That's a requirement, and it's the rule by the FCC. Sorry all you do-it-yourselfers!) Most household installations are easily made to the side of the home with a universal mounting bracket.
