RF Kill (pin 22 - active lo) - controls the RF Kill feature,
which turns all radio transmission OFF. When this pin is
held lo, all RF emissions are suppressed. When the pin is
not held lo, radios revert to normal operation, as defined by
the current configuration of the ES820. This pin would
commonly be tied to a toggle switch.
Reset (pin 23 - active on falling edge) - reboots the box.
Resetting is equivalent to power cycling the ES820. The
reset function is immediate: all current operations are
stopped and the ES820 restarts from the initial power-on
state. This pin would commonly be tied to a push button.
Zeroize (pin 32 - active on rising edge) - restores the
configuration to factory defaults. This pin activates on the
rising edge of the signal. The zeroize function is immediate
when the ES820 is powered on. If the ES820 is powered off
when the zeroize is pressed, the function is executed as
soon as power is applied. This pin would commonly be tied
to a push button.
The 37-pin connector provides support for six LEDs, five
controls, two Ethernet ports, one USB port, and one RS232
COM port.
