PIKE/STINGRAY GOF connectors
PIKE/STINGRAY voltages
The inputs can be connected directly to +5 V. If a higher voltage is used, an
external resistor must be placed in series. Use at +12 V a 820
Ω resistor and
at +24 V a 2.2 k
Ω resistor.

Special warning for all PIKE/STINGRAY models with GOF
connectors:
GOF connectors are very sensitive. Any dust or dirt may
cause damage.
• Always keep the GOF connector and optical fiber plug
clean.
• If GOF connection is not in use, keep GOF dust cover on
the GOF connector.
• Reduce mating cycles to a minimum to prevent abra-
sion.
• Please note that optical fiber cables have a very limited
deflection curve radius.

Voltages above +45 V may damage the optical coupler.

GUPPY
If using voltages higher than + 5 V the input of the cam-
era will be damaged.
To avoid damage of the input, use an external resistor in
series (outside of the camera).
Recommendations for resistors by voltages higher than + 5 V:
• Use at +12 V a 18 k
Ω resistor.
• Use at +24 V a 47 k
Ω resistor.
