4. TROUBLESHOOTING
a. Make sure all component and cable connections are tight and not loose.
b. When connecting a computer to the ST-POE-S16-200W if the Link/ACT LED turns on
but the 100Mbps LED remains off the computer’s connection speed is 10Mbps.
c. If unable to share files once the computer is connected to the ST-POE-S16-200W (i)
check to see if the Link/ACT LED is on; (ii) measure the network cable to ensure the
minimum and maximum lengths are respectively 5 feet and 328 feet; (iii) disable any
software firewall program and (iv) verify that file sharing is enabled via the computer’s
operating system.
d. Ensure the CAT wire connections on the switch and connected devices are using the
same pins and the data wires the correct polarities.
e. The quality of CAT cables has a major effect on the usable distance of transmission
lines and the quality of the displayed signal. Therefore, the actual transmission length
is subject to the quality of the CAT cables being used. Professional grade
transmission lines should be used.
f. If your device is not displaying a video signal check to be sure the transmitter and
receiver each have power. Then check all wire connections for tight fit and correct
polarity.
g. If interference appears on the image check all system connections including camera,
housing, monitor, DVR, etc. as well as ensuring all devices are property grounded.
h. If the image appears twisted or wobbly make sure the wire connections on the
transmitter and receiver have the same polarities. Also check the CAT cable
connections to the RJ-45 connectors are in the correct order.
i. If power is getting to the remote camera but PTZ controls are not functioning correctly
(i) make sure all control cables have tight connections at the remote camera and
controller and (ii) ensure the polarities for the control wires are consistent among the
between the remote camera and controller connections.
