5. WIRING CONNECTIONS
a. The UTP connections to the ST-CCTV-VBAC16 is done using the unit's RJ45
connectors. The advantage of using the RJ45 connector is up to 4 devices can be
share a single UTP cable. If using the RJ45 connector the wiring order follows the
TIA/EIA-568B specification. All UTP wiring should correspond to the figure below:
Note there are four RJ45 connectors each assigned to a bank of channels: one for
Channels 1 – 4, a second for Channels 5 – 8, a third for Channels 9 – 12, and the
fourth for Channels 13 – 16.
When connecting multiple input devices with a single UTP cable you must follow the
connection pattern described below for each RJ45 jack:
Device 1 uses Pins 1 (+) and 2 (-)
Device 2 uses Pins 3 (+) and 6 (-)
Device 3 uses Pins 4 (-) and 5 (+)
Device 4 uses Pins 7 (+) and 8 (-)
b. If connecting a passive balun to the CCTV camera use the ST-CCTV-VB passive
video balun to transition the camera's unbalanced output (BNC coax) to balanced
UTP.
c. If connecting an active balun to the CCTV camera use the ST-CCTV-VBAC-TX active
video balun to transition the camera's unbalanced output (BNC coax) to balanced
UTP.
d. Make a UTP cable connection between each passive/active device's balanced
connector and the ST-CCTV-VBAC16's RJ45 input connectors. Up to 16 devices can
be connected. Be sure to follow the polarities and connection patterns described
above in bullet "a".
e. Using
quality
ST-CCTV-VBAC16's BNC output connector to a display device. Note that each
channel has 2 BNC video output connectors allowing simultaneous imaging of a
channel to two devices (e.g., DVR and monitor).
f.
Connect the ST-CCTV-VBAC16's AC power cable to the unit then plug into an
appropriately rated AC outlet.
