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.)
