Connector Panel Overview
The image below shows the connector panel located on the rear of the Chirp 3200 Series Echosounder. This image
is for a Chirp 3202 Dual Channel system with the possible expansion ports to upgrade to a Chirp 3204 Quad
Channel system.
3.3.1
Input Power
The Chirp 3200 needs to be powered from a AC source. The input voltage range is 90-264 VAC (nominal
120VAC). The power consumption of the Chirp 3202 is 60W and the Chirp 3204 is 100W.
3.3.2
Analog Output
These are standard BNC connections which provide direct access to the analog signal after bandpass anti-aliasing
filters. This interface is useful for oscilloscope viewing of the output signal. The expected signal levels are between
0-5 volts.
3.3.3
Sync In / Out
The Sync In allows the output transmit of the Chirp 3200 to be synced to another piece of equipment. The SYNC
IN looks for a high-to-low-to-high transition with a low cycle hold time of at least 1ms but less than 50ms (min
ping rate). The transmit will occur on the rising edge on the sync signal. The SYNC OUT will provide a signal
from Channel 1.
3.3.4
Transmit (TX) Output
The TX Output connection transfers the high voltage transmit output signal to the transducer as well as the return
echo to the echosounder. CAUTION: Make sure that the Chirp 3200 is not transmitting while connecting or
disconnecting the transducer to the Tx Output connection.
