6.Connection
⑴ Connecting SDI IN/HDMI IN interface of FLOW2000 transmitter with SDI OUT/HDMI OUT interface of
camera or video output device. Connecting SDI loop out interface of FLOW2000 transmitter with SDI IN
interface of monitor or switcher.
5. Pairing

Tips:
1. The menu content of transmitter and receiver is different: Quality mode and wall through
mode can only be selected in transmitter, see fig.8
2. The“MULTI CAST” should change to“ON” in both transmitter and receiver to open one-to-multi
mode.(Both transmitter and receiver need to choose “MULTI CAST ON”)
3. Support firmware upgrading via USB interface.
4. Both transmitter and receiver support manually switch frequency channel.
5. Factory setting is “MULTI CAST OFF”.
6. Choose “MULTI CAST ON”(The transmitter need to pair with every receiver before using
one-to-multimode）
⑴ Switch on both FLOW2000 transmitter and receiver; The “POWER” indicator light in every
receiver should light up when there are multiple receiver, Waiting for jumping to main interface.
⑵ Right pushing the joystick to “PAIR” interface and choose “YES” in both transmitter and
receiver, the“LINK”indicator flashing quickly during pairing(Every receiver should pair with
the transmitter separately when using one-to-multi mode) .
⑶ “LINK” indicator will stop flashing after pairing successful. Device in encrypted transmission
state.

YES
1. Transmitter and receiver should pair in the same time. Every receiver should be paired with the
transmitter separately when using one-to-multi mode.
2. Make sure every receiver have already paired successful before using one-to-multi mode.
3. The paired receiver and transmitter, automatically connected after boot, no need to pair again.
4. Keep 1-2 m distance between transmitter and receiver when pairing to avoid pairing failure.
5. Do not using more than 4 group wireless transmission device to avoid disturbing.
Tips:

⑵ Connecting SDI OUT interface of FLOW2000 receiver with SDI IN interface of monitor or switcher.
When using one-to-multi mode, every SDI OUT interface of receiver should be connected with
SDI IN interface of monitor or switcher.
⑶ Switch on both FLOW2000 transmitter and receiver, “Power”indicator light up，OLED screen
show“WAIT�”then jump to initial interface，see fig.1 or fig.3;Wait until “Link” and “Video”
indicator light up, the transmitter and receiver have identifiable signal inputs and connected
successfully. If the transmitter and receiver have identifiable signal inputs but fail to establish a
connection, the "link" indicator will flash.
Tips:1. After powering the FLOW2000 transmitter and receiver, dial the power switch on the
product to "on""
2. FLOW2000 transmitter support SDI video signal input and HDMI video signal input, the
system automatically identify input video interfaces. System will choose SDI video signal
when both HDMI and SDI interface is connected.
3. When multiple receivers are used simultaneously in the same environment, ensure that
multiple wireless devices have identifiable signal input.
7.High quality mode & Wall through mode
⑴ Connecting SDI IN/HDMI IN interface of FLOW2000 with SDI OUT/HDMI OUT interface of camera
or video output device. Connecting SDI loop out interface of FLOW2000 transmitter with SDI IN
interface of monitor or switcher.
⑵ When using one-to-multi mode, every SDI OUT interface of receiver should be connected with
SDI IN interface of monitor or switcher.
⑶ Switch on both FLOW2000 transmitter and receiver, every receiver should be switch on when
using one-to-multi mode. “Power”indicator light up，OLED screen show“WAIT�”then jump to
initial interface, see fig.1 or fig.3;Wait until “Link” and “Video” indicator light up, the transmitter
and receiver have identifiable signal inputs and connected successfully, right push the joystick
to“PREF”interface, see fig.11.
⑷ It is recommended to choose high quality mode for wireless devices under normal operating
conditions, such as better environment, stronger signal, or more than one
set of wireless devices under the same scene.
⑸ Wall through mode is recommended for wireless devices under complex
operating conditions, such as poor on-site environments, high distance
barriers and only 1-2 sets of wireless devices in the same scene.
(If more than one set is used in the same scene, it is recommended
to use a high quality mode to reduce interaction)
Tips：1. When wireless devices under normal operating condition, choose High quality mode can
get a better video quality, but transmission distance will be cut.
2. When wireless devices under complex operating condition, choose Wall through mode
can get a long transmission distance, but the video quality will be cut.

⑴ Set the antenna on both transmitter and receiver vertically straight up.(See Fig.12)，Set the receiver
faces the transmitter to extend the transmission distance and stabilize the transmission quality.
⑶ Avoid walls, trees and water to reduce signal attenuation.
⑵ Set the receiver as high as possible to avoid interference.
