The preamplified signal feeds one Format-A pair, A, B or C, selected with a rear switch, so other single-pair senders can share the cable. Signal and power pass through on RJ45 jacks, and power arrives remotely or from a fused local terminal block input fed by a 24 Vdc supply such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX power supply\u003c\/a\u003e (the international version of RDL's recommended 24 Vdc supply).
