If you need to disconnect the cable, carefully grasp the plug by the knurled metal outer shell and pull it straight backwards. Use only encoders/sensors supplied by ACS. Please refer to an ACS representative for information about available devices. -
Page 20: Control Connector
CONTROL connector (Fig. 1 Pos.5) is used in user-specific device variants that are out of the scope of the products descri- bed in this manual. Please do not connect any devices to the CONTROL connector until advised by an ACS representative. 5.6 INSTRUMENT FIRMWARE UPGRADE BUTTON The A1560 can be switched to device firmware upgrade (DFU) mode with the DFU (Fig.2 Pos.6) key. - Page 21 Please refer to the A1560 Advanced Configuration document for further information. Use only the included antenna or an an- tenna approved by ACS. Common “router” antennas won’t provide a stable connection despite their connector visibly matching with FIGURE 3 A1560 IN THE LIST OF AVAILABLE WI-FI the A1560 connector.

Page 26: Principle Of Operation
A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT 6.1 ULTRASONIC TRANSMITTER The ultrasonic transmitter of the A1560 is capable of generating pulses of adjustable amplitude, period and duration. The resulting pulse is available on either the OUT or IN connector, depending on current instrument configuration (Transducer Type parameter). Period Amplitude PRINCIPLE OF... -
Page 27: Received Signal Conditioning
A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT In a double-crystal or double-transducer configuration (Double Transducer Type) the pulse is present at the OUT connector, whereas in a single-crystal configuration (Single Transducer Type), the pulse is generated at the IN connector. A transmitter pulse generated by the A1560 is shown in Fig.5. -
Page 28: Time Or Position Related Pulse Generation And Digital Data Acquisition
A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT Figure 6 shows a 2048 sample-long data vector acquired at ADC Frequency = 100MHz and contains information about the first 20.48 microseconds of a pulse-echo sequence. In this case, a SINGLE Crystal Transducer was selected, causing the initial pulse to occur at the same IN input where the acquisition took place. - Page 29 A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT Figure 7 shows three pulses initiated by the A1560’s internal timer with a ~400uS interval. Simultaneous with each pulse, an acquisition was started, and one digital data vector was sent to data acquisition software for each corresponding pulse/ acquisition sequence.
- Page 30 A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT A safe pulse repetition rate (PRR) of 3000 pulses per second should not be exceeded. It is calculated as [Pulse duration in periods] * [Pulses per second] * [Averaging Factor]. If the PRR is exceeded in user-defined parameters, it might be limited internally without any user notification. Acquisition Fixed User...

Page 31: Signal Averaging
A1560 SONIC - OEM ULTRASONIC PULSER/RECEIVER FRONT-END UNIT 6.5 SIGNAL AVERAGING In order to increase SNR, the A1560 can perform several pulse/acquisition sequences over a short period of time to calculate a single averaged data vector and send it to the data acquisition software. The period between pulses shown on Fig.8 is only 50.5 microseconds. -
