The
CBT-610 transmitter is a
car-based L-band RF transmitter for telemetry data. Data is transmitted as an approx 2MHz wide
signal in the L-band. Three different
frequency ranges are available, 1310-1490MHz, 1450-1650MHz and 1510-1710MHz. The unit has 48MB internal memory to
support probability based re-transmission strategies.
Telemetry
data is primarily transferred to the CBT-610
unit from the on-car host unit via HDLC or ARCNET. Payload RF telemetry data rates of up to
2Mbps are supported. Retransmitted
data handshaking for improved lap coverage is not required at many circuits,
but may be provided using a small companion UHF modem (the CBX-450).
