OVERVIEW
The 701 Digital Link (701-DL) provides an interface between a computer running EdgeTech's Discover
sonar acquisition software, and EdgeTech towfish. The 701-DL is self-contained with all interface and
power supply electronics housed within. Communication between the computer and the 701-DL is an
Ethernet LAN connection using TCP/IP protocols. The data and control interface between the 701-DL and
the towfish is via TCP/IP protocols over the ADSL link using the 701-DL Ethernet connection and ADSL
modem. A Sync Trigger port provides an interface with an external TTL trigger. EdgeTech Discover
software interfaces with the 701-DL, monitors and controls the attached towfish and displays and records
acquired sonar and sensor data. The 701-DL fits a 19-inch rack and is delivered mounted independently
in a rugged 2U-SKB case or mounted with an EdgeTech provided computer in a rugged 6U case.
