GDS101 is a one channel
echo sounder. You can
set one draught value for
each frequency. DBS,
DBT and DBK values are
transmitted from active
(displayed) frequency.
External Printer Operation
The optional external printer is started and stopped by the PRINT button in screen 1 and 2. The printer may
be used for continuous printing over a period of time or the current screen contents may be dumped to the
printer for reference if something interesting is observed.
• The PRINT button switches continuous printing on and off.
• The MARK button(s) will write a line mark on the paper if it is pressed whenever the printer is
running.
• If the MARK button is pressed when the printer is online, this will initiate a screen dump of the
present screen contents. If printer is switched off, or not connected, the PRINT button is “dimmed”.
Alarm Settings
Water depth alarm settings are performed from screen 1. Alarm limits are referred to the indicated depth.
The local alarm buzzer may be disabled from screen 9, but the external alarm relay will always operate. The
only way to disable the alarms completely, is to reduce the shallow water alarm to zero depth and increase
the deep water alarm to maximum range. An active shallow water alarm limit must be less than an active
deep water alarm limit. Alarm limits are enforced with hysteresis. A depth alarm may automatically start the
optional printer, if this function is enabled on screen 4.
