RGBlink MSP 315-4 TX

The RGBlink MSP 315-4 TX is the HDBaseT transmitter of the MSP 315-4 set, sold separately. It sends the HDMI 1.4 signal from the source over a Cat 5e or Cat 6a cable to the MSP 315-4 RX receiver: 1080p up to 70 m, 4K at 30 Hz up to 40 m. The cable also carries bi-directional IR and RS-232 and PoE power. The receiver is sold separately.

The transmitter serves as a replacement for or addition to the MSP 315-4 set: it connects to the HDMI source, and a single network cable links it to the MSP 315-4 RX receiver.

Transmitter ports

The transmitter has an HDMI 1.4 input (type A), an HDBaseT output (RJ45), a DC 12 V / 1 A power input, IR input and output (3.5 mm jack), an RS-232 terminal block, an HDCP indicator and a DIP switch to choose between RS-232 control and firmware update.

Works with the MSP 315-4 RX receiver

The transmitter sends the picture to the MSP 315-4 RX receiver, which is sold separately or in the MSP 315-4 set. Thanks to PoE (12 V, max. 125 mA) one unit powers the other, so a power adapter is needed at one end of the line only.
