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 75ohm coaxial cable with BNC connectors connect the
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.
