correct, The DSTS-5A control panel program will open as shown. The input
frequency, width, period, and amplitude display zero until a pulse is received from the
depth sounder. To verify the connection, click the "reset" button. If the connection is
good, the software version will appear briefly in the input frequency display box.
4 CONNECTING A DEPTH SOUNDER TO THE DSTS-5A
4.1 Connect a depth sounder to the IN/OUT connector. Do not connect depth
sounder to the Trig Out connector or the DSTS-5A will be damaged. If the
depth sounder has a balanced output, one of the two inner wires will need to be
connected to the shield and grounded. Consult the manufacturers manual to determine
if one wire and the shield can be used as ground without damaging the depth sounder.
If you are unsure of the correct
connections for a balanced output,
use the EDI BAL-550 accessory.
The BAL-550 is a balanced-to-
unbalanced transformer that has
connections for the shield and two
wires. The output of the BAL-550
connects to the DSTS-5A.
4.1.1 Apply power to the depth
sounder. When the sounder
transmits, the red status LED
will blink indicating that a
pulse has been received.
4.1.2 The input characteristics of the received pulse are displayed on the upper group
of boxes and transmitted echo signals are displayed in the lower group. The results
are updated each time the DSTS-5A receives a pulse or once a second if no pulse
has been received. If the depth sounder is disconnected, the input pulse
characteristics will still display and will not change until a new pulse is received.
Pressing the "reset" button will reset the DSTS-5A and clear the input group of
displays.
