Chassis and I/O Controls
The single front-panel button powers the ES820 Bridge ON
and OFF.

If the Bridge is off, press the Power button to turn it on.
The Power LED will slow-flash green while the Bridge
boots, then light solid green for normal operation.
or

If the Bridge is on, press the Power button to turn it off.
The Power LED will go dark.
Reboot (hard boot) the ES820 by powering it off and back on
again (described above).
The power button is tied to pin 33 or the Bridge’s 37-pin I/O
connector, which is a power control line. Both switches must be
OFF to power the ES820 off.
There are four control lines in addition to Power, described in
Section 4, below.
Radios
The ES820 Bridge contains two radios:
Radio 1 Radio 2 -
802.11a/b/g/n radio
high power 802.11a/n radio
The antenna ports on the ES820 back panel correspond to
these radio numbers as shown in Figure 1.
The last two LEDs on the right of the ES820 front panel
correspond to the radios as shown in Figure 2.
ES820 Bridge: Hardware
37-Pin Input/Output Connector
The connector on the rear panel of the ES820 provides all nonradio input/output for the unit. In order to connect to the ES820,
a cable with a matching connector must be made, using the
required to connector type:
Amphenol MILDTL-D38999 / 26MD35PN

MIL-DTL-38999 Series III TV Shell/Insert 15-35 (socket)
Table 1 defines the pin-out required for the ES820 cable
connector. Most definitions are standard (ex., Ethernet, serial,
and USB). Five pins are unique to the ES820:

Power

Blackout (pin 24 - active lo) - controls blackout mode, which
turns all chassis LEDs OFF. When this pin is held lo, all of
the LEDs on the box are dark at all times. When the pin is
not held lo, LEDs revert to normal operation. This pin would
commonly be tied to a toggle switch.

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
(pin 33 - active lo) - powers the ES820 on and off.
When this pin is toggled lo, the unit is permitted to power up
and boot. The switch state is tied to the chassis ON/OFF
switch: both switches must be OFF to turn the unit off. Tie
this pin to a toggle switch.
ES820 Bridge: Hardware
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.
