OVERVIEW
2.1 INTRODUCTION
The ACU1700A is a 4K Extender that distributes uncompressed 4K @ 60 Hz UHD
video, analog stereo, power, RS-232, and USB 2.0 up to 328 ft. (100 m) over a
single CAT6 or above cable.
The transmitter passes through USB 2.0 and connects to a USB host. The
receiver connects to a USB device. The extender pair enables remote users to
control PC sources with a keyboard and mouse where interactive display
operation, data transmission, or USB streaming device over distance is
required. The extender also supports audio (bI-directional 3.5-mm stereo
passthrough).
With 48-V PoH integrated inside, the extender just needs one power supply
connected to the transmitter to power both units. The 12-V power supply is
secured with a screw-on connector to prevent the power from being accidentally
disconnected. The extender has LEDs to indicate when power is on to the units
and to show signal status when a connection is established to devices.
2.2 FEATURES
- Supports high-speed USB 2.0, up to 480 Mbps, and passthrough over the RJ-45 interconnect up to 328 feet (100 m).
- Offers bi-directional Analog Stereo, and RS-232 pass-through over the RJ-45 interconnect.
- Via CAT6/6A/7 cable, supports 4K x 2K @ 60 Hz or 1080p @ 60 Hz output up to 328 ft. (100 m)
- Via CAT5e cable, supports 4K x 2K @ 60 Hz or 1080p @ 60 Hz output up to 288 ft. (90 m) or 1080p @ 60 Hz output up to 32(100 m)
- Complies with HDMI 1.4 with 4K @ 60 Hz (chroma sub-sampling 4:2:0 8-bit only).

INITIAL INSTALLATION
- Using quality HDMI cables, connect an HDMI source (such as Blu-ray, games console, satellite/cable TV, media server, etc.) to the HDMI IN connector of the Transmitter.
- Connect a good-quality, well-terminated CAT5e or better cable between the RJ-45 OUT connector of the Transmitter to the RJ-45 IN Input port of the Receiver. Using quality HDMI cables, connect the HDMI display device (LED/LCD display or projector) to the HDMI OUT port of the Receiver.
- Connect the included 12-V power supply to the Transmitter. The PoH function carries power along the length of the cable one way to power the Receiver. No additional power supply is required for the receiver.
- Power on all devices. Check the status of indicators on the front panel. The Power and Link LEDs will light ON solid while the Status LED should be blinking.
- Most USB devices are supported, however, some are not. Gaming controllers and keyboards are not compatible with this extender.
