UBR1211A module is designed to receive a single pair of Audio signal from CSP products, and transfers the signal to the Balanced or Unbalanced Audio Output on the front panel. Set the switch on the front panel to determine which pair of UTP CAT 5 cable to receive the signal and goes to the output of this module.
UBR1211A module only receives one pair of CAT5 cable by setting the switch, this means UBR1211A accepts 3 pairs of signals from other CSP transceivers to RJ45 Input jack, the additional CSP Receivers could be chained to the LOOP OUT jack. The other two single pair of CSP receivers could be chained together with UBR1211A, or a single two pair of receiver could be connected. By using same pair of CAT5 cable, the additional CSP receivers could be chained together to distribute same signal to different locations.
UBR1211A 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. UBR1211A may be powered from other modules through the Pair D of TP CAT5 cable. When the power is supplied to this module, front panel LED will light on.
