INSTALLATION
Inspection
Please examine your Switcher Sentinel® 3 carefully for any damage that may have
been sustained during shipping. If any damage is noted, please notify the shipper
immediately and retain the packaging for inspection by the shipper. The package
should contain the Switcher Sentinel® 3, this manual and/or CD, 7 foot BLUE
straight-through CAT 5 cable, 7 foot GRAY crossover CAT 5 cable, and the 7.5 to
9.0 VDC wall transformer. Manuals may also be downloaded from our web site.
Installation
The Switcher Sentinel® 3 interfaces to external equipment through removable
euroblock screw terminals. The terminals accommodate wire sizes from 16 - 28
AWG solid or stranded wire. Before installing a wire, remove the euroblock screw
terminal plug and turn each capture screw fully counterclockwise. Strip each con-
ductor to a length of 0.25” and insert the conductor fully into the terminal. Turn the
capture screw fully clockwise to secure the conductor.
CAUTION!
If this product is to be used for other than analog audio switching, the
silence sensor circuitry MUST be disabled. By disabling the circuitry, automatic
switching, along with the web VU meters will not function. To disable the silence
sensor, disconnect all connections and power. Remove the cover by unscrewing the
two capture screws on the bottom. Locate and remove RN1, the 14 pin, 1K ohm
resistor network and stow it for future use. Re-assemble the product, re-attach all
connections and apply power.
CAUTION!
Installation of the Switcher Sentinel® 3 in high RF environments
should be performed with care. The station ground should be connected to the des-
ignated chassis ground terminal using a 20 to 24-gauge wire.
Surge Protection
The Switcher Sentinel® 3 has built-in resistance to voltage changes; we recommend
that you use a power surge protector or line conditioner on the incoming AC line.
Lightning strikes and/or other high voltage surges may damage your Switcher
Sentinel® 3 and connected equipment if it is not properly protected. For lightning
protection devices, check out www.polyphaser.com and www.itwlinx.com.
UPS Standby Power System
We recommend that you connect your Switcher Sentinel® 3 to a UPS system. A
UPS helps minimize the risk to the Switcher Sentinel® 3 and provides power dur-
ing a power outage.
NOTE: During a power outage, the signal is routed from input one to the output.
“NET” network RJ45 connector
Connect one end of the supplied CAT5 (straight or crossover) cable to the desired
ETHERNET (WAN/LAN) or PC network port.
