UBD-1053A provides four signal output with DC power supply for CSP products. The INPUT RJ-45 jack receives a single pair of UTP CAT5 cable from one or more CSP Transceivers. The LOOP OUT RJ-45 jack allows the input signal to pass through to another UBD-1053A or other CSP products. Up to 10 distributors daisy-chain together is recommended. Three sets of Dual-LED meters are provided on the front panel of UBD-1053A. One meter monitors the audio level on each of the three CSP audio pairs.
There are two DC power input jacks on the front panel, provides the DC power to one of DC input jacks. And then uses power jumper cable provides a simple method of interconnecting one distributor module to the next, so multiple modules can be operated from a single power supply.
UBD-1053A module could be powered from a 24VDC power supply by using terminal block or DC jack on the front panel, and the power also could be provided to all the connected modules by Pair D. When the power is supplied to this module, front panel LED will light on.
