Termination of TP cable

Figure 2-10 details the recommended termination of TP cables in accordance with the TIA/EIA T 568A wiring standards.

CAUTION	Connect the sleeve to ground (Gnd). Connecting
	the sleeve to a negative (-) terminal will damage the
	audio output circuits.

If only an audio signal, no video, is received, connect a ground wire between the chassis ground and an earth ground in the equipment rack or other grounded device. If the receiver is not grounded, a crackling sound may be heard in the audio output.

TP R BNC AV — Plug a standard IEC power cord into this connector to connect the TP R BNC AV to a 100 to 240VAC, 50 Hz or 60 Hz power source.

If the distance between the transmitter and receiver is too great for the receiver to power the transmitter, the video image will be missing, distorted, or noisy, or the receiver’s Manual/Auto LED will flash. The transmitter
