The RMQ-230 Series quad split, LCD video monitors are highperformance 23" professional LCD monitors that support advanced
10-bit digital processing technology and also 3D comb filter and
de-interlace, accurate scaling engine, GAMMA correction and color
temperature adjustment to achieve the best possible image display.
The RMQ-230 Series supports 4-channel 3G/HD/SD-SDI/CVBS signal
and a single HDMI signal input. They can simultaneously display four
signal inputs, with three typical display modes including one full
screen display, one big-with-three small screen displays and four
uniform size screen displays.

Technical Function Overview26
1.Read, keep, and follow all of these instructions; heed all warnings.
2.Do not use this equipment near water, rain or moisture.
3.Use only a dry cloth to clean the equipment.
4.Do not install near any heat source such as a radiator, heat register,
amplifier, or stove.
5.Do not attempt to plug the unit into a two-blade outlet (with only
two prongs of equal width).
IMPORTANT:
By design, these monitors will only plug into a three-prong outlet for
your safety. If the plug does not fit into your outlet, contact an
electrician to replace the obsolete outlet.
6.Protect the power cord from being walked on or pinched,
particularly at plug’s source on the equipment and at the socket.
7.Use only the attachments/accessories specified by the
manufacturer.
8.Unplug the equipment during lightning storms or when unused
for long periods of time.
9.Use of a cart is neither recommended nor approved by Wohler.
10.Refer all servicing to qualified service personnel. Servicing will be
required under all of the following conditions:
•The equipment has been damaged in any way, such as when
the power-supply cord or plug is damaged.
•Objects have fallen onto the equipment; or the equipment has
been exposed to rain or moisture, or liquid has been spilled
onto the equipment.
The symbol to the left warns of electric shock hazard inside the unit.
Disconnect the power cord before removing access panels when
installing upgrades. Only qualified service personnel are to operate the
equipment with covers removed, and are to exercise caution to avoid
personal injury.
Installation Recommendations
Heat Dissipation
The ambient temperature around the unit should not exceed 40°
Celsius (104° Fahrenheit). Allow plenty of space around the unit for air
circulation.
Mounting/Bracing
Stands for desktop mounting are provided. The fixed desktop stand
resists tipping over. The adjustable stand may need bracing when
raised to its higher positions.
Wall mounting kits (not provided) are available for semi-permanent
installations. Ensure that the lock hardware will resist movement from
mobile vehicles or seismic vibrations.
Connections and Cable Recommendations
We recommend that you limit the length of the cables that you use for
feeding HD-SDI signals sources to the HD-SDI inputs of the RMQ
Series units and that you use a Belden 1694A cable (or equivalent). The
HD-SDI inputs (IN1 and IN4) can be up to 150 meters (492 feet) in
length for 1.5 Gbps (HD), more for 270 Mbps (SD) and less for 3Gbps.
HDMI 1.3 or 1.4 cable lengths of 2m (6 feet) are guaranteed
to work well. Four meters (12 feet) lengths of high quality
cable should work well enough, but is not guaranteed for all
situations. Longer HDMI cables often degrade signal
quality. Active extender transmitter/receiver pairs can be
used to cover long distances.
Electrical Interference
Be careful to properly terminate/ground signals and avoid
mismatched cable types and other similar causes of undesired
reflections in digital signal systems. If severe enough, such reflections
can result in corruption of the digital data stream. As with any audio
equipment, maximum immunity from electrical interference requires
the use of shielded cable. The internal circuitry ground is connected to
the chassis.
Power
The unit comes with a standard 19VDC/4.7 A external power adapter
and connects an A/C mains power source (65W, 100 to 240 VAC, 50/
60Hz) through the IEC connector provided on the power adapter.
When the mains plug or appliance coupler is used as the disconnect
device, the disconnect device connection should remain accessible to be
operable.
