UR2212A module is designed to provide RCA jacks on the front panel, and receives the signal from Pair B, C of UTP CAT5 cable. The signal from Pair B routs to RCA(L) and Pair C routs to another RCA(R). There is an additional RJ-45 jack on the back panel, to connect with other CSP receiver modules, so all three audio pairs A,B,C and power pair D could pass through both RJ-45 jacks. And the system allows the chain connection up to 10 receiver modules.
UR2212A module could be powered from a 24VDC power supply by using the rear panel terminal block, and the power also could be provided to all the connected modules by Pair D of UTP CAT5 cable. When the power is supplied to this module, the front panel LED will light on.
