3.2.8.5 Key Zeroize
The encryption keys can also be manually erased by holding down the monitor and emergency
buttons during radio power-up. These two button inputs both connect to a dual transistor Q5001,
which will release the Key_ZEROIZE signal sensed by MACE's TPRO (U5003-M2). Once this
condition is sensed (floating high), the encryption keys will be erased.
To troubleshoot the encryption circuitry, refer to the flowcharts in
Chapter 5 “Troubleshooting Charts”
.

Bluetooth Module Interface
A 60-pin connector (J3001) contains various interfaces from the Vocon Board that are made
available to the Bluetooth Option Board.
Table 3-15
shows the various groups of interfaces available at J3001. The interface groups are
described in the next section.
3.2.9.1 Bluetooth Option Board Signal Groups
From
Table 3-15
, the Bluetooth Interface is divided into 10 signal groups: Power, Ground (GND),
One-Wire, GPIO, Camera, I2C, SDIO, SSI, USB, and Type 1/GPIO.
3.2.9.2 Power / Ground
The power supplies available at the Bluetooth Interface are , SW_B+, VCC_2.8, and
VCC_1.8 (see DC Power Supplies section for details). is routed to pin 30 (J3001-30),
SW_B+ is routed to pins 27,29, and 31 (J3001-27, J3001-29, J3001-31), VCC_2.8 is routed to pin 23
(J3001-23), and VCC_1.8 is routed to pin 24 (J3001-24).
The ground pins are pin 1, 2, 25, 26, 28, 34, 37, and 59 at J3001.
