5.6 AUXILIARY FUNCTIONS
The Coaxitron receiver is capable of operating up to
four (4) remotely activated auxiliary functions. Each
auxiliary output may be individually converted at the
receiver for momentary or latching operation. Refer to
Figure 15 for the desired jumper location. When in the
latching mode, activating the same AUX function will
toggle the function from on to off.
The AUX outputs are buffered to provide a continuous
10 VDC at 25 mA to drive small relays, lamps or some
other external device. Refer to Figures 16 and 17 for
Figure 15. Jumper Settings, Receiver/Driver Mother Board
