5. Safety
Please avoid exposure to water and do not install unit in
high humidity areas. Make sure all connectors (optical
and copper) are properly secured.
Please verify that power supplied is matching the input
required for operation:
- for AC adapter input
：
100~260V, 50~60Hz
- for DC input
：
5V/3A
Stop using devices if they have been exposed to water or
mechanical shocks affecting the physical form of the
units.
For outdoor installation please consider installing surge
protectors/lightning protection devices for the SDI
copper side interfaces.
6. Troubleshooting
The RB-3GSDI-01 series converters are simple plug and
play devices. There are very few adjustments to be made
for proper operation. Check below list for potential
adjustments:
- no light on POWER LED: please check power sources,
make sure AC power is available and properly connected.
Replace AC adapter with a similar one
-
no light on SDI LED: please check copper SDI
connectivity: each SDI LED reflects local copper
connection; make sure each SDI LED is ON, the end
without SDI LED
“
ON
”
should be reset with a power cycle.
If connectivity is proper and LED is not turning on, please
use a different RB-3GSDI unit
- noise seen as

”
effect on video quality: too much
fiber attenuation or weak/improper copper SDI
connectivity. Multiple potential causes:
▪
normal fiber attenuation due to too long fiber
circuit or improper high attenuation fiber
splicing: please measure total fiber attenuation
with an OPM (optical power meter) and OLS
(optical laser source) to determine the level of
optical attenuation on your fiber circuit. If local
splicing is bad, replace or redo the fiber splices
▪
fiber attenuation caused by fiber overbending:
please observe fiber path and reduce bends in
the fiber run
▪
fiber attenuation caused by dirty optical
connectors: clean connectors with a fiber
cleaning pen (female) or fiber cleaning cassette
(male)
▪
improper copper SDI connectivity: please check
quality of copper wiring
▪
improper copper coaxial cable used: make sure
impedance of the video coaxial cable for SDI
interface is 75 Ohms
▪
AC power interference: please avoid running AC
lines over or under the fiber extenders. Make
sure the AC power lines have proper grounding.
