The Kramer TP-574 HDMI, Bi-Directional RS-232 & IR over Twisted Pair Receiver is a device for receiving converted HDMI plus control commands via twisted pair (e.g. Cat 5) cables and converting them back to HDMI, RS-232, and IR signals for output to a display device. Used with a Kramer TP-573 transmitter (not included), the TP-574 receiver extends the range of an HDMI source so that it can feed a display across a facility, for instance. While HDMI cables have an approximate range of 50', Cat 5 cables can carry pristine HDTV video and associated audio signals over hundreds of feet.
The range of the system's transmission varies based on the signal resolution, graphics card, display, and cables used. Kramer has tested the device with their own cables. The device receives signals from up to 295' away at 1080i, or up to 98' at 1080p using a shielded BC-DGKat524 cable. With a shielded BC-DGKat623 cable, the range extends to 295' at 1080i or up to 230' at 1080p. Using a shielded BC-DGKat723 cable the range is up to 330' at 1080i or up to 295' at 1080p.
The TP-574 supports bi-directional RS-232 and infrared signals, which means that a computer source, for example, can be used to control and receive data from a display device hundreds of feet away. Control signals are received with converted video and audio signals over the twisted pair cable and outputted to the display device. By supporting HDMI, the TP-574 outputs video and multi-channel audio to an HDMI display such as a plasma or LCD flat-panel TV set or a computer display.
Note: The use of shielded twisted pair cables is required.
Powered from the optional transmitter end, so a power supply is not required
HDMI 1.4 includes within the spec support for 3D pass-through, Deep Color, x.v.Color, Lip Sync, HDMI Uncompressed Audio Channels, Dolby TrueHD, and DTS-HD. HDMI supports existing high-definition video formats (720p, 1080i, and 1080p60), as well as standard definition formats such as NTSC or PAL
Passes EDID and HDCP signals from source to display
Passes Hot Plug Detect (HPD) signals from the display device to the source
Power Connect feature allows both the receiver and the transmitter (not included) to be powered from the transmitter's 12 VDC power source when the devices are within 150 ft (50 m) of each other, as long as the cable can carry power
TP-573 / TP-574 system goes into standby mode when the HDMI input is not connected
Three similar-sized units can be rack mounted side-by-side in a 1U rack space, using an optional RK-3T adapter (not included)
