(2) Antenna (3) LED (4) 8-pin ConnectorThe CR Series radios are available in the following bands: 450 MHz and 900 MHz. These products share a common housing and electrical interface in order to simplify the machine installation and integration.The 450 MHz and 900 MHz band radios are used to receive GNSS data in Compact Measurement Record (CMR) format. This data is received from a reference receiver. The data is transmitted to one or more roving receivers for precise machine positioning. These radios can also communicate 2-way data between an office computer and the machine.These radios are offered in the following configurations:Single Band Radio - 900 MHzDual Band Radios - 900/2400 MHz 450/2400 MHzThe CR Series radio has antenna connections on the top, an electrical connector on the bottom, and a LED on the front. Refer to Table 5 for the LED states.

Illustration 16 g01569877
The AS400C angle sensor is a highly accurate sensor that is capable of measuring up to +/- 45 degree slopes.The AS400C angle sensor is mounted on the bowl. The angle sensor measures the cross slope of the cutting edge of the bowl.Contact Description of the Angle Sensor
Illustration 17 shows the pinout information for the 6-Pin socket receiver on the angle sensor.

The AccuGrade system is an RTK rover configuration. The system requires a GPS base station somewhere near the project.Note: GPS base stations are not supplied by Caterpillar.A GPS base station consists of the following components:
GPS Receiver
GPS Antenna
Radio
Cables
Power SupplyThere may also be a tripod or mast for the GPS antenna and the radio, depending on the particular site. For construction sites where work can continue for a long time, use a semi-permanent location such as the roof of the site office. A reliable power supply is needed.Make sure that the base GPS antenna is clear of obstructions, reflected GPS signals (multipath), and sources of electro-magnetic interference such as power lines.The base station's data radio must be elevated several meters off the ground in
