RSP1 Radar Processor

Datasheet

7.2.2 Control Outputs

Digital outputs are high active push-pull circuits with typically 10mA driving power.

Pin

Function, if high (3.3V)

Remark

LED_BUSY

RSP is busy and is not detecting

Active during power-on learning

LED_DETECT

Active, as long as movement is detected

including hold time

DETECT_OUT

same signal as LED_DETECT

use for driving external hardware output

LOW_BANDWIDTH

set according to parameter S08

optional use for external amp bandwidth limitation

CMD_TX_ENABLE

reserved for future RS-485 expansion

active during serial transmission

CMD_TX

Command interface UART Tx

see chapter 7.3 Host Command Interface

CMD_RX

Command interface UART Rx

see chapter 7.3 Host Command Interface

DETECT_SIGNAL

same signal as DETECT_OUT

optional use for digital signaling to host device

7.3 Host Command Interface

This is a 3.3V asynchronous UART interface:

Pins:

Input: CMD_RX, output CMD_TX

Physical data: 38'400Baud, 8 databit, 1 stopbit, no parity, no handshake

Protocol:

Client-Server protocol. RSP1 acts as server. See 8 Software Parameter Settings

This interface is supported by the RSP_Terminal tool.

7.4 SPI / IO Interface

This interface is reserved for future versions of RSP1.
