Both switches must be OFF to power the ES820 off.There are four control lines in addition to Power, described in Section 4, below.4RadiosThe ES820 Bridge contains two radios:The antenna ports on the ES820 back panel correspond to these radio numbers as shown in Figure 1.

ES820 Bridge: Hardware35 37-Pin Input/Output ConnectorThe connector on the rear panel of the ES820 provides all non-radio 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 / 26MD35PNFigure 3. 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 (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.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 121 3111
ES820 Bridge: Hardware4when 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.Table 1.
