VTX module Overview:
HCL-DLB VTX module was designed for video data wireless
transmission with two way wireless data link. This OFDM radio
module works at 800MHz, 1.4GHz and 2.4GHz bands, with frequency
hopping technology (FHSS) to make sure better stability signal
communication.

strong. |
Wireless Networking with HCL-DLB module:
DLB VTX module supports two operating modes: Access Node or Central
Node. It can be managed through Web UI or AT command via uart3. DLB
module supports features of maximum 16 Access Nodes connected to a
Central Node. All of the Nodes are in a same wireless LAN and share
the whole transmission bandwidth (maximum 30Mbps@20MHz throughput).
Data from Central Node to Access Node, we call downlink, and data
from Access Node to Central Node, we call uplink. Uplink and
downlink stream ratio can be controlled through web UI or AT
command. When using DLB module for Point-to-Point transmitting,
uplink and downlink share the whole transmission bandwidth (maximum
30Mbps@20MHz throughput) too. DLB module supports networking mode:
Point -to-Point, Point-to-Multipoint, Relay, and Mesh (specify mesh
version when order).
Point-to-Point networking type:
Point to Multipoint networking type
Relay networking type
Mesh networking type (Specify)

FAQ
Q1. This VTX module seems to support IP camera, what if I want to
use a camera with HDMI or SDI video output?
A: Yes, the default video input is IP RJ45 Ethernet port, if your
camera only has HDMI, SDI, AHD or AV output, you need to buy our
mini encoder device to encode the video and audio signal into
digital data for transmission. At the receiver end, you can connect
it directly to your computer or NVR. If you want to output to an
HDMI monitor, you can also buy our decoder device to convert the
digital data back into HDMI video and audio signals.
