3.3 Flatness adjustment mechanism
3.3.1 Three-axis and six-way adjustment(Cabinet)
When the stitching between the cabinets is not smooth and needs to be adjusted, the
position can be fine-tuned by the flatness adjustment screw. The positions of adjusting screws
are designed on the top (2 pcs), side (2 pcs) and back (4 pcs) of each cabinet (red circle in the
following picture). Use flatness adjustment screw and 3mm L-shaped hexagon adjustable
wrench to fine tune the cabinet position.

4. Product Cabling
Preparation before cabling
Before applying power and signal source to the screen, please check power and data cables
connections carefully and make sure they are wired correctly. Use a multimeter to test the L, N
and PE lines in AC power input port and make sure the three lines are not short-circuited.
Power cable connection instructions: Please calculate and select the appropriate model of
distribution cabinet or socket according to the maximum power consumption. Please consult your
electrician or distribution cabinet manufacturer for specific selection scheme. The input voltage
of the cabinet is 100-240V/AC. The 3×1.5 mm2power cable is used from the distribution box to
the cabinet. Please confirm the input voltage, the number of cabinets loaded on each power cable
will be different upon different voltages and product models. (Please feel free to contact our
after-sales service department if you cannot confirm).
4.1 Power Supply Wiring
Taking a [4x4] HC1.2 Ⅱcabinet for example, data and power wiring schematics are shown
below:
The total power of 16 HC1.2 Ⅱcabinets is 16 x 0.6 x 0.3375 x 520W=1.7kW. First, connect the
cabinets in series with connecting power lines, and the 3×1.5 mm2power cable is used for
connecting from the cabinet of bottom layer to the distribution box or socket.
NOTE:WHEN THE INPUT VOLTAGE IS 220V, EACH 3×1.5 MM
2POWER CABLE CAN CARRY UP TO 16 CABINETS.WHEN THE INPUT
VOLTAGE IS 110V, EACH POWER CABLE CAN CARRY UP TO 8CABINETS.

- 18 - New HC Series User Manual
4.2 Signal Cable Wiring
The signal cable of standard version uses RJ45 CAT5 network cable(The HC0.7 Pro Ⅱuses CAT6A
network cable or above), and the network cable interface of the cabinet can be used for input and
output. For the "S" type of up down connection, please calculate the resolution according to the
pixels of each cabinet and connect the signal cables according to the loading range of the sending
card.
When the cabinet is single-card version, DATA1 is in use and DATA2 is vacant.
When the cabinet is dual-card version, If signal backup is required, DATA1 port is the signal
network port on the main card and DATA2 port is the signal network port on the backup card.
Note: The range of loaded pixels of each net port cannot exceed 655360 points(except HC0.7 Pro
Ⅱ).
