The 4100 system consists of the 272 towfish and the 560 control PC, running Edgetech Discover software.
Notes: See Analog Sidescan driver and Appendix A to configure analog inputs. Online Sonar Control: Identical to Edgetech 4100 driver. Control is via RS232 COM port.Ĭonnection: Select COM port through which the control messages are output.Īnalog inputs are configured in the ASCAN.EXE program (Analog Sidescan Monitor) which runs minimized when this driver is used. Sidescan input is via A/D card (see analog sidescan above). Interface is via the ACI (Analog Control Interface).
If trouble persists, stop the program, cycle power at the CM-2 control box, then restart the program.Ī USB driver, available through C-MAX, is required for this interface.ĭriver for Edgetech 272 sidescan. Notes: If having trouble starting up, stop the sidescan survey program for When deselected, reverts to auto-auto-gain. Gain Hold: When selected, holds the current towfish gain settings. Sidescan Sonar driver using USB interface for control and data.Ĭonnection: No configuration is needed for the USB interface. Shallow Mode: Allows towfish operation in 1.5m water or less.
Online Sonar Control: The standard control functions (ping on/off, range, SV and frequency selection) are available under Tools Menu, Sidescan Device Control.
Refer to the CM-2 manual for further details. Hypack expects the following message: S,RangeFreqCode,Altx0.1m Other information exchange (control / status ) is through a COM port - 4800 baud, 8 data bits, 1 stop bit, no parity.ĬOM offset is configurable within the CM-2. Sidescan signal and trigger use the analog interface (See Analog Sidescan above). Sidescan Sonar driver using COM port for control and analog interface for input.Ĭonnection: There are two connections. This is displayed in the towfish sensor window, but is also converted to depth. Notes: The telemetry data stream may include pressure.
The pulse type, length, and frequency can be changed as well as hardware and software gain (on the Benthos side). Online Sonar Control: The control functions are available under Tools Menu, Sidescan Device Control. Sonar Head Offsets: For towfish, enter 0, 0 as offsets are applied to the tow cable driver (TOWCABLE.DLL) in Hypack survey. The driver is hardcoded to these ports so the port field in setup is ignored. It uses port 5009 for ping data and 5010 for telemetry. According to Benthos documentation, the IP address of the system should always be 192.168.0.17. Notes: See Appendix A: Analog Sidescan Interfacing.ĭriver for 1624/1625 sidescans with control.Ĭonnection: Uses a TCP network connection. For towfish, enter 0, 0 as offsets are applied to the tow cable driver (TOWCABLE.DLL) in Hypack survey. Sonar Head Offsets: Forward / Starboard: For hull mount, enter offsets relative to boat origin. The device is plug and play no configuration required in Sidescan Hardware.
Test: Simulate data provides a dummy amplitude time series for each channel.Ĭonnection: Connected via a National Instruments multifunction I/O device PCI board, PCMCIA card or USB. Threshold: This is the A/D count level at which trigging occurs. Gain: Gain constant (voltage multiplier).
Trigger: Ping is on low to high or high to low transition of the trigger signal. Input: Select one of the voltage range options.
The NI USB-6221 is a USB device which should work in all Windows versions supported by HYPACK.Īdditional Setup: Clicking Analog Sidescan Monitor (on the taskbar) during Sidescan Survey will show the following form for sidescan configuration on the fly. The NI 6024E is a PCMCIA device which works fine in Windows XP and earlier but is not supported by National Instruments in Vista, and therefore can not be used in HYPACK under Vista. Setup Form: The setup form allows you to select the analog input device. The digitized data are passed to Sidescan Survey through shared memory. A separate program (Ascan.exe) is run automatically to sample the ping trigger and digitize the analog inputs. Add CMAX CM-2 Notes.ĭriver providing 2-channel sidescan information from analog input. Added GeoAcoustics DSSS and Benthos 1624/1625 sections. Internal trigger option for USB analog sidescan.
