Chapter: 3. Installation
Options
Repeaters/Slaves
Graphic CRT (VGA), LCD displays or digital depth slave repeaters may be connected to the system. The
graphic repeaters may require the installation of line driver units dependant on the distance between the
main system and the repeater. See “Fig. 3.5. Data Communication Interfaces.” on page 42 and “Fig.
3.6. Data Communication Interfaces.” on page 43.
Remote Keyboard
The unit may optionally be operated from a remote keyboard. If you have combo terminal PCB version
E (or higher), a jumper is provided (JP900) for 12 V. See “Fig. 3.8. Terminal board connections” on page
48. Otherwise modications must be made (contact SKIPPER).

Remote Sounding Control
This option lets the GDS102 being controlled remotely in continuous/edge/level/single ping modes.
If installed, these options are accessible on screen 3. See “Fig. 2.4. Screen 3. Power adjustment and
options.” on page 16, “Fig. 3.8. Terminal board connections” on page 48, “Fig. 3.9. Input/Output
Circuitry 1” on page 49 and “Fig. 3.10. Input/Output Circuitry 2” on page 50 for more details.

Optocoupler 2 output
J100 Symbol J100 # Description
OPT2DC 18 Direction Collector.
OPT2VC 17 Velocity Collector.
OPT2EE 16 Common Emitter.
The “silent” (non-transmitting) and “sounding” (transmitting) modus is indicated by the change of the state
of optocoupler OPT2VC/OPT2EE (J100 pin 16 and 17).
• When in “sounding” (transmitting) modus, the light emitting diode inside the opto coupler is ON and
the “switch” is closed.
• Alternatively, when in “silent” (non-transmitting) modus, the light emitting diode inside the opto coupler
is OFF and the “switch” is open.
• When the sounder is turned o, the described “switch” will remain open, indicating no transmission.
