2.2 System Description
The MRC CodeRunner 2 transmitter is designed to be both an
analog and digital transmitter for ENG portable applications.
CodeRunner 2 can accommodate a variety of analog and digital
inputs, and apply either analog or digital modulation.
CodeRunner 2 is an integrated, flexible solution consisting of:
• A rack mounted Indoor Unit (IDU), typically mounted
inside an ENG vehicle.
• A mast mounted Outdoor Unit (ODU), also called the RF
Unit (RFU).
A typical installation is shown in Figure 2-1.
PowerOptionsThe CodeRunner 2 can be operated from
115 V / 220 V AC mains power, or from 18-36 V DC vehicle
power. Power is supplied to the IDU, which in turn powers the
ODU via the cable harness between them.
Analog/DigitalOptionsThe CodeRunner 2 is digital-ready,
which means it can be ordered and installed as a full-featured
analog radio. Then later, it can be upgraded just by adding the
digital MPEG/COFDM Module.
Band&FrequencyOptionsThe CodeRunner 2 is designed to
cover the bands below. It can be ordered as a single-band unit or
in a dual-band configuration to cover any two of these bands.
• 2-3 GHz
• 6-7 GHz
• 12-13 GHz
Band and frequency information is stored in the ODU, which
means switching bands after installation is very simple: just plug
in the RFU for the new band, and the IDU will automatically
configure itself for the new band.
