18 Connection TB8100 Installation Guide© Tait Electronics Limited June 2005Reciter Auxiliary DCInput from PMU The system interface board in the reciter has an auxiliary DC inputconnector. DC from the auxiliary DC output on the PMU can be suppliedto the +AUX_V pin on the system interface connector via this input (see“PMU Auxiliary DC Output” on page 16).The pin allocations for the auxiliary DC input on the system interface boardare given in the following table. Older boards use the 4-way connector,while the TaitNet RS-232 board and all other boards manufactured afterMarch 2005 use the 2-way connector. Note that pins 1 & 3 and pins 2 & 4on the 4-way connector are linked. Refer to “System Connections” onpage 20 for the pin allocations for +AUX_V on each system interface board.The DC output from the PMU is 13.65VDC, 27.3VDC, or 54.6VDC(depending on the model). Although this power output is isolated, thenegative side of the supply is grounded on the system interface board to givea +V output.2.2 12V PA Power Saving Control ConnectionTo enable Power Saving in the 12V PA, you must connect digital out 1 onthe reciter’s system interface connector to pin 1 of the Power Saving controlconnector on the rear panel of the PA. Once this connection is made, thePA will shut down whenever the reciter goes into Deep Sleep mode. Formore information on the operation and configuration of Power Saving, referto “Power Saving” in the Installation and Operation Manual.Note When a base station with a 12V PA is configured for Deep Sleep,digital out 1 is dedicated to Power Saving control and should notbe used for any other Task Manager function.Two ways of making the Power Saving control connection between the 12VPA and reciter are described below. The circled numbers in the followinginstructions refer to Figure 2.2 on page 19.Method 1 1. Connect one end of the Power Saving control cable b (Tait partnumber 219-02971-00) to the Power Saving control connector c atPin Description Links1 +V input2 ground3 +V input4 ground2-way connector - external view1234124-way connector - external view
