6.3 Getting to Know the TP-2xl Video Line Receiver
The Kramer
TP-2xl is a high performance composite video to twisted pair receiver, designed to receive video signals
over long distances using common twisted pair cable. Combined with the
TP-1xl this set of machines is an upgrade of
the
TP-1N/TP-2N pair (now discontinued). Using good quality cable, the system can maintain the bandwidth of an
industrial color video signal up to 4000 ft. (1.3km) vs. 1000ft of the old version, and broadcast quality (up to 12 MHz)
for as much as 750 ft. (250 meters.) At shorter distances, bandwidth of 100 MHz is easily achieved. The set provides
gain and high frequency compensation controls to optimize levels in extremely long runs. Kramer twisted pair
adapters solve remote monitoring requirements without using more costly fiber or wireless transmission systems.
Using the
RK-50R kit, a set of TP-1xl/TP-2xl can be mounted in a standard 19” rack.
NOTE
For Installation, operation, maintenance and troubleshooting instructions please refer to sections 8-13.
