3.5 AUXILIARY FUNCTIONS
The Coaxitron® receiver, using a Revision J or newer receiver/driver PC board, is capable of operating up to four remotely activated auxiliary functions. Each auxil- iary output may be individually converted at the receiver for momentary or latching operation. Refer to Figure 4 to set jumpers for auxiliary functions. When in the latch- ing 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 other external devices. Refer to Figures 5 and 6 for examples of typical circuits used for auxiliary functions.
Figure 5 shows a typical connection using the latching command to operate an external device for auto iris or manual iris operation (AUX 1 latches manual iris and AUX 2 latches auto iris.)
