Introduction
UD100 is designed for 4k projector warp, stacking and curved screen edge blending with the flexibility
to provide multiple processing modules to control from 1 to 4 projectors. UD101 is integrated with one
processing module to control one projector, UD102 for 2 projectors, UD103 for 3 projectors and UD104 for 4
projectors. One UD104 can execute 4 projector edge blending with projectors and signal source without any
additional equipment or splitter. Multiple UD100 can be cascaded for large scale display.
Each processing module has 4 input ports, 1 loop through port and 1 HDMI output port. All inputs
support up to 7680*2160 @30Hz, 5760*1200 @60Hz/4096*2160 @60Hz input resolution with 4:4:4 full color
sampling. DisplayPort input can support up to 7680*4320 @30Hz. Output supports up to 4096*2160 @60Hz.
It is integrated with 10-bit high end processor, motion adaptive de-interlace, low angle smooth algorithm,
3:2/2:2 pull-down and supports non-VESA standard input timings. Programmable EDID can optimize input
timing to get the best video result.
Advanced warp technology is embedded in UD100. User can use front panel keypads, IR controller,
USB, WebGui and Ethernet to perform edge blending and sophisticated geometry alignment up to 17x17
control points. Linearity Grid Line Adjustment for compete line movement and Corner Wall image adjustment
for mapping image at 90 degrees corner are new functions in geometry alignment. Separate R, G, B gamma
correction for edge blending region color fine-tune, individual color correction for each output and 9 regions
black level uplift to compensate light leakage in the projector are also standard functions in UD100. Users can
see real time geometry and color adjustment to get optimized result.
HDMI loop out supports daisy chain connection up to 8k/2k @30Hz / 4096x2160 @60Hz and allows
large display with multiple units cascaded. Video wall function is to crop and allocate source image for each
projector and set overlap pixels for edge blending. Complete curved edge blending can be achieved through
remote controller, USB and Ethernet without additional device except for signal source and projectors.
PIP (picture in picture), POP (side by side) and 3/4 split view MultiViewer are standard functions. PIP
image size is from 320*180 up to 1920*1200. In one UD104, user can display up to 16 different input contents
on the screen. Image 90/180/270 degrees rotation and flip are embedded in UD100. It provides flexible
system configuration.
UD100 is an ideal solution for simulation. It can connect with inputs from multiple PCs and combine
them into one seamless image. Unnecessary image can be masked out. It also provides flexible displays in
edge blending system. For a 3x projector edge blending system, user can configure as 1+1+1 independent
display, 1+2 (two projectors blended) and all-in-one (three projectors blended). User can also execute edge
blending with projector at portrait position without rotating source image to increase image height. It is a good
fit with laser projector without the limitation in installation angle.
Using UD100, users can replace high end projector with low-cost projector without lens shift, warp and
edge blending. It provides easy configuration, low entry barrier, cost effective, reliable and flexible solution.

2.5. HDMI Loop Out for daisy chain connection
➢HDMI Loop Out is for daisy chain connection. It is not an input port. Loop Out provides the same
unprocessed source signal from HDMI-1/HDMI-4/HDMI-7or HDMI-10 inputs. All the other input
signals will not be looped out. If user wants to execute edge blending through other input signal,
please add video distributor and feed signal to all channels.
➢User can connect any Loop Out signal to any HDMI input port in other channel or other GeoBox.
No specific connection sequence is required. Once the signal can be fed to all channels, user can
execute edge blending.
➢Normally user can connect up to 10 stages through daisy chain connection under 4k signal. The
daisy chain connection number is related to the quality of HDMI cables and signal source
resolution. Good cable or lower source resolution can connect more channels. User can also use
multiple outputs PC or HDMI splitter at the front end to increase system resolution or the
connection number for large scale display.
➢If loop out port is not connected, user can connect to a monitor for signal source monitoring
purpose.
2.6. How to use IR Remote Controller
➢IR remote controller has full functions for the operation of UD100.
➢IR receiver is on Front Panel. One 3.5ø mm audio connector for IR extender is located at Back
Panel of UD100. 1.8m IR extension cable is equipped in the packing. User can add audio cable to
extend the distance up to 20 meters.
➢IR remote control system is possible to be interfered by the environment and cause abnormal or
discontinuous operation. Under this condition, Ethernet operation may be the best choice.

2.7. System settings: Box ID, RS232, Ethernet
➢Box ID, RS232 and Ethernet settings shall be executed through CH-1. The setting result will be
applied to complete unit. It can be changed through OSD menu, WebGui or PC Tool.
➢Default IP address is 192.168.0.100.
➢When multiple units are used at the same time, user can set different IP address in each UD100 so
that each UD100 can be controlled independently.
➢For multiple channel operation, user can select channel directly for further operation. It is nothing
to do with Box ID and IP address.
2.7.1. Box ID
➢The range of Box ID is 0 ~ 99 for RS232 command.
➢If user uses remote controller to execute individual box operation, the Box ID range is 0 ~ 9.
2.7.2. RS232 settings
➢RS232 is designed with DB-9 connector. User can select baud rate between 11520 and 9600.
➢UART protocol for the control from RS-232 or Ethernet is available in the website.
2.7.3. Ethernet
➢User needs to connect GeoBox to WiFi Router or switch/hub through RJ45 to LAN port. Then user
can control the system through Ethernet.
➢Crossover UTP cable can be used for direct connection between PC and GeoBox. User needs to
set PC TCP/IPv4 with the same domain segment as GeoBox (for instance, to set IP address at
192.168.0.105) and subnet mask at 255.255.255.0). In some PC, normal UTP cable can be used.
