Kramer Intros New HDMI Over Twisted Pair System
Kramer Electronics introduced the TP-573 and TP-574 twisted pair transmitter and receiver for HDMI, bi-directional RS-232, and IR signals.
Kramer recently introduced a similar new solution for transmitting DVI over twisted pair.
The TP-573 transmitter converts the input signals into signals that can be run over shielded twisted pair cables. The TP-574 receiver then converts the input signal back to HDMI, RS-232, and IR signals. The TP-574 receiver is an adjustment-free product, featuring automatic calibration that adjusts the line level and EQ control as needed. Both units feature bandwidth of up to 1.65Gbps, HDTV as well as HDMI 1.3 compatibility, and HDCP compliance.
With the TP-573 and TP-574 an HDMI signal can be transmitted up to 295 feet at 1080i resolution and up to 98 feet at 1080p resolution when using Kramer's shielded BC-DGKat524 cable, company officials said. Kramer's shielded BC-DGKat623 cable extends the 1080p distance capability to 230 feet and Kramer's next-generation BC DGKat7a23 shielded cable should have a range of 295 feet at 1080p, according to the company.
The company did not offer performance characteristics for non-Kramer cables.
The TP-573 and TP-574 each incorporate LED status lights to indicate power on, input signal detection, and output device detection. The TP-573 and TP-574 pass the HPD and CEC signals from the source to the display device over the twisted pair cable. The TP-573 employs Kramer's Power Connect feature in which a single connection to the transmitter powers both units. The required 12V DC is transmitted through the twisted pair cable, along with the other signals, to the receiver.
The TP-573 and TP-574 are housed in compact DigiTools enclosures and are available for $295 per unit.
