MODEL 852 DIGITAL ECHO SOUNDER
WIN852.EXE
c/w External Trigger Option
Special Notes:
Before using the external trigger feature, ensure that your 852 Echo Sounder has been
supplied with the External Trigger Hardware Option. The external trigger must be a 0 to
5 volt TTL pulse with a minimum length of 100 microseconds.
To enable the Model 852 echo sounder for external trigger mode, the WIN852.INI
provides the following control:
[ES Settings]
ESExternalTriggerControl
Bit 0: Trigger Edge: 0 = NEG, 1 = POS
Bit 1: Trigger Enable: 0 = Disable, 1 = Enable
Bit 2: Trigger Mode: 0 = Manual, 1 = Automatic
When enabled for external trigger, the echo sounder will transmit as soon as it detects the
external trigger pulse. If a trigger pulse has not been found after a period of 100
milliseconds, it will transmit as normal.
Please refer to Imagenex Document "852 echo sounder spec.pdf" for more information.
